About how far apart do aesha and Josh live

Vesnalui [34]

Answer:

D. about 8.5 mi

Step-by-step explanation:

To go from Aesha to Josh, you go 6 units right and 6 units up.

Each unit is a mile, so you go 6 miles right and 6 miles up.

Think of each 6 mile distance as a leg of a right triangle, and the direct distance from one place to the other as the hypotenuse of the right triangle. Use the Pythagorean theorem to find the length of the hypotenuse.

a^2 + b^2 = c^2

The 6-mile legs are a and b. c is the hypotenuse.

(6 mi)^2 + (6 mi)^2 = c^2

c^2 = 36 mi^2 + 36 mi^2

c^2 = 72 mi^2

c = sqrt(72) mi

c = sqrt(36 * 2) mi

c = 6sqrt(2) mi

c = 6(1.4142) mi

c = 8.5 mi

HELP PLZZ ASAP !! a. The value of x is 6 , what is the value of y?

erastovalidia [21]

Answer:

a). y = 4.5

b) Scale factor = $\frac{3}{4}$

Step-by-step explanation:

a). Since, polygon Q is the scaled copy of polygon P

Both the figures will be similar.

Therefore, their corresponding sides will be proportional.

$\frac{x}{y} =\frac{4}{3}$

If x = 6,

$\frac{6}{y} =\frac{4}{3}$

y = $\frac{3\times 6}{4}$

y = 4.5

b). Since, polygon Q is the scaled copy of polygon P,

Polygon Q will be the image of preimage polygon P.

Scale factor = $\frac{\text{Length of a side of the image}}{\text{Length of a side of the preimage}}$

= $\frac{3}{4}$

Four points from a line are shown in the table below.

Dvinal [7]

Answer:

Correct choice is D. $y=-x+3$ .

Step-by-step explanation:

pick any two points from the table say (0,3) and (1,2)

Now we we can use both points to find the equation of line.

slope $m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-3}{1-0}=\frac{-1}{1}=-1$

now plug slope m=-1 and any point say (0,3) into point slope formula

$y-y_1=m\left(x-x_1\right)$

$y-3=-1\left(x-0\right)$

$y-3=-1\left(x\right)$

$y-3=-x$

$y=-x+3$

Hence correct choice is D. $y=-x+3$ .
