Answer:

y = 3/8x + 1/8

Step-by-step explanation:

The slope of a perpendicular line is the opposite and reciprocal of the original slope.

-8/3 -> 3/8

Find the new y-intercept.

y = 3/8x + b

2 = 3/8(5) + b

2 = 1.875 + b

0.125 = b

y = 3/8x + 1/8

Answer:

slope of  line segment XY is -2.

Step-by-step explanation:

plz gve me points thank you

From the given graph, we have

coordinate of the point X is (-1,3)

coordinate of the point y is (1,-1)

The slope of a line through the point  is given by

Here, we have

On substituting these value in the above formula of slope, we get

Therefore, the slope of  line segment XY is -2.

Step-by-step explanation:

let the unknown be x

4(8 + x) = 32

32 + 4x = 32

4x = 32 - 32

4x = 0

x = 0 ÷ 4

x = 0

if you wanna check,

4(8 + 0)= 32

32 + 0 = 32

32 = 32

hope I got it right&^^,good luck!

Answer:

B.  12.43 ft

Step-by-step explanation:

cosine = adjacent / hypotenuse

cos 43° = y / 17

multiply both sides by 17

17 (cos 43°) = y

cos 43° = 0.7314 (use your calculator)

y = 17 x 0.7314

y = 12.43 ft.

Answer:

x = 20

Angle 1 = 120

Step-by-step explanation:

(4x + 40) = (2x + 80)

4x + 40 = 2x + 80

2x + 40 = 80

2x = 40

x = 20

2(20) + 80

40 + 80

120

Angle 1 is a vertical angle from (2x + 80) so they have the same measurement.

B, 0.625

Step-by-step explanation:

The constant of proportionality is y/x

from the equation y = kx ->  y/x = k

Answer:

c 1.6

Step-by-step explanation:

The constant of proportionality is what determines the relationship between y and x. If r is the constant of proportionality then an example is y = rx . The value of y is dependant on how the given value of x is effected by the constant of proportionality.

Answer:

The y-intercept is 4. The third option is correct

Explanation:

The equation of a line is written as:

y=mx+b

Where m is the slope and m is the y-intercept or the point where y crosses the x-axis.

The given function is f(x)=4-5x.

It can be rewritten as

f(x)=-5x+4.

We can recognize the slope m=-5 and the y-intercept b=4

First option: Incorrect. The y-intercept is not -5

Second option: Incorrect. The y-intercept is not -4

Third option: Correct. The y-intercept is 4

Fourth option: Incorrect. The y-intercept is not 5

The y-intercept of the equation f(x) = -5x + 4 is 4.

The y-intercept is the value of y when x = 0.

The slope intercept equation can be express as follow:

where

m = slope

b = y-intercept

Therefore, let's model the equation f(x)  = 4 - 5x to the slope intercept form.

f(x) = -5x + 4

Therefore, according to the slope-intercept equation, the slope is -5 and the y-intercept is 4.

The y-intercept is the value of y when x = 0.

Answer: B: 3(30-G)

Step-by-step explanation:

A following table titled Apples showing Pounds, Cost per Pound and Total.

This means that

1 pound of Fuji apples costs $3

(30 - g) pounds of Fuji apples cost  

The total is  3(30-G)

Given problem;

  A  = 4 π R²

  To solve for R, we have to make it the subject of the expression.

Since

      A  = 4 π R² , follow these steps to find R;

    Multiply both sides by [tex]\frac{1}{4\pi }[/tex]  

 A x [tex]\frac{1}{4\pi }[/tex]  =  [tex]\frac{1}{4\pi }[/tex] x 4 π R²

          [tex]\frac{A}{4\pi }[/tex]   = R²

Then find the square root of both sides

        √R²  = [tex]\sqrt{\frac{A}{4\pi } }[/tex]  

            R  = [tex]\sqrt{\frac{A}{4\pi } }[/tex]

The solution is [tex]\sqrt{\frac{A}{4\pi } }[/tex]

Step-by-step explanation:

Using translation concepts, it is found that function g(x) is defined by:

[tex]g(x) = \left|\frac{x}{5}\right|[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The absolute value parent function is defined by:

f(x) = |x|

When it is strecthed horizontally by a factor of 5, it means that the domain is divided by 5, hence the function is given by:

[tex]g(x) = \left|\frac{x}{5}\right|[/tex]
