15 plus the difference of 10 and a number X is 15 (X=?)

15+(10-x)=15 would be your equation if that is what you are looking for.

Find the average rate of change over the interval [-1,2] (from x = -1 to x = 2) for the graph below

Lyrx [107]

Hello!

Find the coordinate where x = -1:

At x = -1, y = 1, so the coordinate is (-1, 1).

Find the coordinate where x = 2:

At x = 2, y = -2, so the coordinate is (2, -2).

Find the rate of change between the points using the slope formula:

$slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Plug in the coordinates above:

$slope = \frac{-2-1}{2-(-1)}$

Simplify:

$slope = \frac{-3}{3} = -1$

Thus, the rate of change between the points is -1.

Find MO and PR ............................................................

ddd [48]

MO = 12 and PR = 3

Solution:

Given $\triangle M N O \sim \Delta P Q R$ .

Perimeter of ΔMNO = 48

Perimeter of ΔPQR = 12

MO = 12x and PR = x + 2

If two triangles are similar, then the ratio of corresponding sides is equal to the ratio of perimeter of the triangles.

$$\Rightarrow \frac{\text{Perimeter of }\triangle MNO}{\text{Perimeter of }\triangle PQR} =\frac{MO}{PR}$

$$\Rightarrow \frac{48}{12} =\frac{12x}{x+2}$

Do cross multiplication.

$$\Rightarrow 48({x+2})= 12(12x)$

$$\Rightarrow 48x+96= 144x$

Subtract 48x from both sides.

$$\Rightarrow 48x+96-48x= 144x-48x$

$$\Rightarrow 96= 96x$

Divide by 96 on both sides, we get

⇒ 1 = x

⇒ x = 1

Substitute x = 1 in MO an PR.

MO = 12(1) = 12

PR = 1 + 2 = 3

Therefore MO = 12 and PR = 3.
