If x equals 7, then find the matching value for y.<br> -2x-2y=-2
mihalych1998 [28]
Y = -6.
-2(7)-2y=-2

-14-2y=-2

you need to move -14 to the other side by canceling out -14 with +14, and add +14 to -2, giving you -2y=12. -2/12=-6

A brass ornament has a volume of 24cm^3.
dedylja [7]

For this case we have that by definition, the density is given by:

d = \frac {M} {V}

Where:

M: It is the mass

V: It is the volume

According to the data of the statement we have:

V = 24 \ cm ^ 3\\d = 8.7 \frac {g} {cm ^ 3}

So, the mass is given by:

M = d * V\\M = 24 \ cm ^ 3 * 8.7 \frac {g} {cm ^ 3}\\M = 208.8 \ g

Thus, the mass of the brass ornament is208.8 \ g

Answer:

208.8 \ g

For the graphed exponential equation, calculate the average rate of change from x = −3 to x = 0.
iragen [17]

Answer:

-\frac{7}{3}

Step-by-step explanation:

To solve this, we are using the average rate of change formula:

m=\frac{f(b)-f(a)}{b-a}

where

m is the average rate of change

a is the first point

b is the second point

f(a) is the function evaluated at the first point

f(b) is the function evaluated at the second point

We want to know the average rate of change of the function f(x)=0.5^x-6 form x = -3 to x = 0, so our first point is -3 and our second point is 0. In other words, a=-3 and b=0.

Replacing values

m=\frac{f(b)-f(a)}{b-a}

m=\frac{0.5^0-6-(0.5^{-3}-6)}{0-(-3)}

m=\frac{1-6-(8-6)}{3}

m=\frac{-5-(2)}{3}

m=\frac{-5-2}{3}

m=\frac{-7}{3}

m=-\frac{7}{3}

We can conclude that the average rate of change of the exponential equation form x = -3 to x = 0 is -\frac{7}{3}
