Evaluate the following linear equation for the given values y= -3x+1 and x is -5, -2, -1 and 4.
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.

Find x. Round to the correct number of decimal places.
Step-by-step explanation:
Using Trigonometry,
Let the height be AD, angle containing 90° be B and the angle containing 65° be C, respectively.
cos 30° = AD/40
AD= 40√3/2 = 20√3.
<DAC = 25°.
cos 25° = AD/AC

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°

What is the height of a triangle that has an area of 24 in.2 and a base with a length of 8 in.?
Answer:⬇️⬇️⬇️⬇️
Step-by-step explanation: Area of a triangle = ½base times height⇒ A = ½bh
Given that the area is 24 and the base is 8, we would have this equation
24 = ½(8)h
24 = 4h divide both sides by 4
6 = h So the height of the triangle is 6 feet
CHECK
A = ½bh
24 = ½(8)(6)
24 = 4(6)
24 = 24√
Express 8mm as a percentage of 4mm

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

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.

Given: AD, What statements are true regarding the given statement and diagram? EB bisects LAEC IZCED is a right angle. ZCEA is a right angle. a mZCEA = 1 2 (mZCEB) C mZCEB = m_BEA B mZ DEB = 135° MZAEB = 35° A E
The option first, option second, option fourth, and option fifth are correct.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
We have:
AD
EB bisect angle AEC
From the figure:
Angle CED is a right-angle triangle
So,
Angle CEA is also a right-angle triangle
Angle CEB = Angle BEA = 90/2 = 45 degrees
Angle DEB = Angle CED + Angle CEB = 90 + 45 = 135 degrees
Thus, the option first, option second, option fourth, and option fifth are correct.

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 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.

If varies directly as y and y = 15 when = 25. If = 155 then y is
Answer:
y = 93
Step-by-step explanation:
I assume the other variable is x.
"If x varies directly as y and y = 15 when x = 25. If x = 155 then y is"
Direct variation:
x = ky
25 = k * 15
k = 25/15
k = 5/3
The direct variation equation is
x = (5/3)y
155 = (5/3)y
y = 155 * 3/5
y = 93
