Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
Answer:
A linear function is described below
Step-by-step explanation:
A linear function describes a proportional relationship in with 1 input has only 1 output, however more than one input may have the same output. There may be many steps to find the outcome of an input
Determine whether the equation 4x + y =6. If so graph the function
Answer:
4x + y = 6 is a function. The graph will cross the y-axis at point (0, 6) and crosses the x-axis at point (1.5, 0)
Step-by-step explanation:
Solve for y: 4x + y = 6
y = -4x + 6
Slope is -4 and the y-intersect is 6.
Now solve for x when y = 0. This action will give you the x-intersect.
4x + y = 6
4x + 0 = 6
4x = 6
x = 6/4 or 1.5
The graph will cross the y-axis at point (0, 6) and crosses the x-axis at point (1.5, 0)
Write the equation of the line in slope-intercept form The line is parallel to y + x =3 and passes through the point (-12, 0)
Step-by-step explanation:
The line is parallel to y + x =3
=> y = -x+3
the slope = -1
passes (-12, 0)
the equation would be :
y-0 = -1(x+12)
y = -x -12

Answer:68
Step-by-step explanation:
5+9*7=68
Write root 3 x root 6 in the form b root 2 where b is an integer.
3 root 2
root 3 x root 6 = root 18
to write it in its simplest form, we have to reduce the number to a situation, where we have a product that includes a perfect square and and another number
let me break that down
let us use another example;
root 8
we think of the largest perfect square that is also a factor of 8
then, we conclude to our answer; 4
next, we think of the number that multiplies with 4 to give is 8 and that is 2
so, we bring the 4 outside by square rooting it and everything gives us
2 root 2
to open this, we just square the 2 outside and multiply it by the 2 inside to give us root 8
if we apply this example to our question,
root 18 = root 9 * 2
this is because 9 is the largest square and factor of 18 and 2 multiplies with 9 which gives us root 9 * 2
then, we square root 9 to give us 3 and we bring this 3 out to give us
3 root 2
hope this helps.

To find the x-intercept, you need to see where the line intersects the x-axis, the horizontal line with numbers on it. The line intersects the x-axis at (2, 0). Therefore, the x-intercept is (2, 0).
To find the y-intercept, you need to see where the line intersects the y-axis, the vertical line with numbers on it. The line intersects the y-axis at (1, 0). Therefore, the y-intercept is (1, 0).
There are two ways to find the slope. The easiest one in my opinion is rise over run, but you can also use an equation too. I am going to be showing you the rise/run method, but you can also ask if you want the equation method as well. First of all, the line goes to the left, not the right, so we know that the slope is going to be negative. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x). All you need to do is calculate the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run). I am going to choose point (1, 0) if I go up by 2 and over by 4, I'll get to the point (-4, 3) that also lands on the line. 2/4 is 1/2. Therefore, the slope is -1/2.

After adding the ice, they noticed the soup became watery and did not taste very good. They wanted to figure out a way to quickly cool the soup but not water it down. They had two separate ideas. The older brother wanted to place the entire bowl into the freezer and let it sit for 2 minutes. The younger brother wanted to divide the soup into two smaller bowls and then place both of them in the freezer for 2 minutes. Describe how you could use science ideas and tools to decide which brother has the better method of cooling their soup. As you explain your answer, talk about energy and explain how it moved. You can include a diagram, but it must be explained with words.
Answer: This is your opinion and is probably graded for you stating your opinion.
Step-by-step explanation:
If you use the older brothers method, your soup would not cool down as fast in 2 minutes, because it's a lot of soup in one bowl, just like how a cup of water would freeze faster than a whole lake. If you want your soup to completely cool down in 2 minutes, use the younger brothers method.
Hope this helped.
One end of a wire is attached to the top of a 24-foot pole; the other end of the wire is anchored to the ground
18 feet from the bottom of the pole. If the pole makes an angle of 90° with the ground, find the length of the
wire.
Answer:
30 feet
Step-by-step explanation:
We can use Pythagorean theorem for this question because the pole and the wire that is anchored to the ground forms an right triangle because the pole makes an angle of 90 degrees.
One side of the right triangle formed is equal to 24 feet, and because the wire that is anchored to the ground is 18 feet from the bottom of the pole, another side is 18 feet.
Pythagorean theorem states that [tex]a^{2} +b^{2} =c^{2}[/tex]. With a and b being the sides of the right triangle and c being the hypotenuse. In this problem, the length of the wire is equal to the hypotenuse of the triangle.
a=24 and b =18. 24 squared is equal to 576, and 18 squared is equal to 324. We add 576 and 324, which is 900. This means that [tex]c^{2}[/tex] =900. To find c, we find the square root of 900, which is 30. Therefore, the length of the wire is 30 feet.
Answer:
30 feet
Step-by-step explanation:
1. The 24-foot pole and the 18 feet from the bottom of the pole form a right angle, meaning that when you add the length of the wire, a right triangle forms.
2. "24-foot pole" is the height, and "18 feet from the bottom of the pole" is the base. The length of the wire is the hypotenuse.
3. To find the hypotenuse of a right triangle, we can use the Pythagorean theorem to solve it: [tex]a^2 + b^2 = c^2[/tex], where a = leg of triangle, b = leg of triangle, and c = hypotenuse (or in this case, the wire).
4. Now, let's apply the formula:
[tex]18^2 + 24^2 = c^2[/tex]Step 1: Simplify both sides of the equation.
[tex](18*18)+(24*24)=c^2[/tex] [tex]324 + 576 = c^2[/tex] [tex]900 = c^2[/tex]Step 2: Take square root of both sides.
[tex]\sqrt{900} =\sqrt{c^2}[/tex] [tex]30 = c[/tex]Step 4: Check if solution is correct.
[tex](18*18)+(24*24)=(30*30)[/tex] [tex]324 + 576 = 900[/tex] [tex]900 = 900[/tex]Therefore, the length of the wire is 30 feet.

The next model of a sport car will cost 6.7%less than current model.the current model cost $46,000.how much will the price decrease in dollars?what will be the price of the next model
Answer:
$42,918
Step-by-step explanation:
There are basically a couple ways to do this
First way:
46,000 x 0.067 = 3,082
46,000 - 3,082 = 42,918
Second way
46,000 x (1 - 0.067)
46,000 x 0.933 = 42,918
Either way works; just use which one you prefer

Please help with geometry
Answer:
m∠2 = 68°, m∠3 = 112°, m∠4 = 68°
Step-by-step explanation:
m∠3 = m∠1 ( Vertically opposite angles )
m∠3 = 112°
m∠2 = 180 - m∠1
m∠2 = 180 - 112
m∠2 = 68°
m∠4
Solution 1:
m∠4 = m∠2 (Vertically opposite angles)
m∠4 = 68°
Solution 2:
m∠4 = 180 - m∠1
m∠4 = 180 - 112
m∠4 = 68°

if abc~ dec , what is the length of de? Please help
Answer:
B) 12
Step-by-step explanation:
Given:
ΔABC ~ ΔDEC
AB ~ DE
AC ~ DC
BC ~ EC
We will just use ratios and substitute DE as x:
[tex]\frac{AB}{AC} =\frac{DE}{DC} \\\\\frac{16}{20} =\frac{x}{15} \\\\20x=240\\\\x=\frac{240}{20} \\\\x=12[/tex]
DE = 12
The measure of the side DE of the triangle DEC will be 12. Then the correct option is B.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees. If two triangles are similar, then the ratio of the corresponding sides will remain constant.
The triangles ABC and DEC are similar triangles. Then the ratio of the corresponding sides will be the same.
DE/AB = CD/AC
From the diagram, AB = 16, AC = 20, and CD = 15. Then the measure of the side DE will be given as,
DE/16 = 15/20
DE/16 = 0.75
DE = 16 x 0.75
DE = 12
The measure of the side DE of the triangle DEC will be 12. Then the correct option is B.

Use the point and the slope to graph each line. Write the equation of the line. The line passes through point (2,-2) and is parallel to a line that has slope -1.
Answer:
y= -x
Step-by-step explanation:
slope- intercept form
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is -1, m= -1.
Substitute m= -1 into the equation:
y= -x +c
To find the value of c, substitute a pair of coordinates into the equation.
When x= 2, y= -2,
-2= -2 +c
c= -2 +2
c= 0
Thus, the equation of the line is y= -x.

Answer:
The Noble gases are the least reactive of any elements on the periodic table.
Explanation:
All of the elements in Group Zero are noble gases. The list includes helium, neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are also called inert gases because they do not react with other elements of periodic table. The reason behind their inertness is that their outermost shell is complete and they do not have the tendency to lose or gain electrons.
Answer:
The Halogens form acidic compounds with hydrogen
Explanation:
The non metals in group 7 of the periodic table are known as the halogens. When they react wit hydrogen their respective acid is formed For example, hydrogen chloride (HCl)is produced when hydrogen combines with Chlorine and in the same way Hydrogen Bromide is produced when Bromine reacts with hydrogen.
Answer:
The halogens are the most reactive among all the non metals
Explanation:
The non-metal elements in Group 7 are known as the halogens which consist of five chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They get less reactive as we go down the group. This is the opposite trend to that seen in the alkali metals in Group 1 of the periodic table which are reactive among metals.
