To solve the inequality -25 > -5(x + 2.5), first multiply -5 by the number and variable in the parentheses.
-25 > -5x - 12.5
Now add 12.5 to both sides of the equation.
-25 + 12.5 > -5x - 12.5 + 12.5
-12.5 > -5x
Now divide -12.5 by -5 to get the answer.
-12.5 ÷ -5 is 2.5
You would think the final answer is 2.5 > x, but that is not true because -5 is negative and when a negative number is divided to both sides of an inequality, the sign gets flipped.
So, the real answer is 2.5 < x, or x > 2.5.

The answers are...
h(-1) = 3
h(0) = 0
h(4) = -6
Step-by-step explanation:
In order to solve each of these, simply input the value of x into the equation.
f(x) = -3x
f(-1) = -3(-1)
f(-1) = 3
f(x) = -3x
f(0) = -3(0)
f(0) = 0
f(x) = -3x
f(2) = -3(2)
f(2) = -6
Answer:
128
Step-by-step explanation:
The area of the larger rectangle is \begin{align*}8(16)=128 \ \mathrm{units}^2\end{align*} and the area of the smaller rectangle is \begin{align*}5(10)=50 \ \mathrm{units}^2.\end{align*} If we compare the areas in a ratio, it is \begin{align*}50:128 \ = \ 25:64 \ = \ 5^2:8^2.\end{align*}
