If y=kx, where k is a constant, and y=24 when x=6, what is the value of y when x=5?A. 6B. 15C. 20D. 23

Marizza181 [45]

First, we will find the value of k

We can do this by sybstituting y=24, x=6 in;

y=kx and then solve for k

24= k(6)

divide both-side of the equation by 6

24/6 = k

4 = k

k=4

Then when x = 5, we will substitute x=5 and k=4 in; y=kx and then solve for y

y= (4)(5)

y = 20

joja [24]

The side length of the square is a rational.

What is the area of the basement?

Any lower storey of a structure that is partially or completely below the lowest contiguous proposed ground level is referred to as a basement floor, provided that the portion of the storey above ground level does not exceed 75 cm.

Given: Taylor uses tape to mark a square play area in the basement for her daughter.

The area measures 28 ft2.

We know that the area of square is side length square.

As the area measures 28 square feet, so the side length of the square is, 28 feet.

Since 28 is a rational number.

Therefore, the side length of the square is a rational.

Find an equation for the surface consisting of all points p for which the distance from p to the x-axis is 5 times the distance

guajiro [1.7K]

Distance from P to the x-axis = 2x distance from P to the yz-plane

Distance to the x-axis of a point P=(x,y,z) is (y^2+z^2)^1/2 
Distance to the yz-plane of a point P=(x,y,z) is x 

So your equation is: 
(y^2+z^2)^1/2 = 2x 
=> y^2 + z^2 = 4x^2 
=> y^2 + z^2 - 4x^2 = 0

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Write an equation of the perpendicular bisector of the segment with endpoints G 9,8       and H 3,2      .

Norma-Jean [14]

Answer:

y = -x + 11

Step-by-step explanation:

The equation of a straight line is is given by:

y = mx + b; where m is the slope and b is the y intercept

The equation of the line joining G(9, 8) and H(3, 2) is given as:

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-8=\frac{2-8}{3-9}(x-9)\\\\y-8=x-9\\\\y=x-1$

The perpendicular bisector of the line joining G(9, 8) and H(3, 2) is perpendicular to the line joining G(9, 8) and H(3, 2) and passes through the midpoint of line joining G(9, 8) and H(3, 2).

Let (x, y) be the midpoint of the line joining G(9, 8) and H(3, 2). Hence:

x = (9 + 3)/2 = 6

y = (8 + 2)/2 = 5

The midpoint = (6, 5)

Two lines are perpendicular if the product of their slopes is -1.

The line joining G(9, 8) and H(3, 2) has a slope of 1, hence, the slope of the perpendicular bisector would be -1.

This means that the perpendicular bisector has a slope of -1 and passes through (6, 5). Using:

$y-y_1=m(x-x_1)\\\\y-5=-1(x-6)\\\\y-5=-x+6\\\\y=-x+11$

The equation of the perpendicular bisector is y = -x + 11
