Answer:

x = 42

Step-by-step explanation:

$\frac{18}{15}$ = $\frac{x}{35}$ ⇔ $\frac{6}{5}$ = $\frac{x}{35}$ ⇔ $\frac{6*7}{5*7}$ = $\frac{x}{35}$ ⇒ x = 42

Jeffrey calculated the slope between two pairs of points. He found that the slope between -5, 6 and -3, 2 is -2. He also found t

Cerrena [4.2K]

Answer:

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope between -5, 6 and -3, 2

substitute the values in the formula

$m=\frac{2-6}{-3+5}$

$m=\frac{-4}{2}=-2$

step 2

Find the slope between (-1, -2) and (0, -4)

substitute the values in the formula

$m=\frac{-4+2}{0+1}$

$m=\frac{-2}{1}=-2$

step 3

Find the slope between (-3, 2) and (0, -4)

substitute the values in the formula

$m=\frac{-4-2}{0+3}$

$m=\frac{-6}{3}=-2$

therefore

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2

What is the area of a pizza with a diameter of 12 inches?

nikdorinn [45]

The formula for area of a circle is π × radius², and the radius is half of the diameter, which means that your final expression is π × 6² = 36π = 113.1 inches². I hope this helps!

Only answer if you're very good at Math.

Shalnov [3]

Answer:

Solution given:

f(x) = x +1 and g(x) = x²,

now

(gºf)(x) =g(fx)=g(x+1)=(x+1)²

D) (gºf)(x) = (x + 1)^2
