Answer:

y – y 1 = m ( x – x 1 ) m = your slope ( x 1 , y 1 ) = your point y – ( − 5 ) = − 3 2 ( x – 1 ) y + 5 = − 3 2 ( x – 1 ) Now we need to do a little algebra to get the equation in standard form: A x + B y = C , where A, B and C are relatively prime integers. y + 5 = − 3 2 x + 3 2 3 2 x + y = 3 2 − 5 now let's multiply through with 2 to get rid if the fractions: 2 ( 3 2 x + y = 3 2 − 5 ) 3 x + 2 y = 3 − 10 3 x + 2 y = 7

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

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√

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)

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:

Step 1: Simplify both sides of the equation.

Step 2: Take square root of both sides.

Step 4: Check if solution is correct.

Therefore, the length of the wire is 30 feet.

The option first, option second, option fourth, and option fifth are correct.

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.

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°

Answer: 0

Explanation: Divide 2 and 11, and you get 2/11 and multiply that with 55 you get 10 and 10 - 10 equals 0! ^^

the answer of this question is B

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

0.90 = 20√3/AC

AC = 38.49. is the value of x.

please try to understand the marking accordingly.

Drive Rate Time Distance

Mr. Chandler's drive 35 4.5+x 35(4.5+x)

Mrs. Chandler's drive 65 x 65x

35(4.5+x)= 65x

157.5 + 35x= 65x

157.5 = 30x

Hope this helps! Pls give brainliest!

Answer:68

Step-by-step explanation:

5+9*7=68

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

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.

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.
