The first step for solving this expression is to move the variable -3m to the left side and then change its sign.
4 - 2m + 3m > 7
Now move the constant to the right side and change its sign.
-2m + 3m > 7 - 4
Collect the terms on the left side.
m > 7 - 4
Lastly,, subtract the numbers on the right side to get your final answer.
m > 3
Let me know if you have any further questions.

Range is the value of y
f(x)=-x²+5
when x=-1, f(x)=-(-1)²+5=4
when x=2, f(x)=-(2)²+5=1
so 1<y≤4
the second piece: f(x)=2x-3
when x=2, f(x)=2(2)-3=1
when x=5, f(x)=2(5)-3=7
so 1≤y<7
union of the two parts of y: 1≤y<7
[1,7) is the answer.
Answer:
2⁴ + r
Step-by-step explanation:
Change the sentence into a expression.
Note that r is a variables.
"Raise 2 to the 4th power..." means 2 to the 4th power, or 2⁴.
"...then add r to the result" means: + r
Combine the two terms:
2⁴ + r is your answer.

Simplify if need be.
2⁴ = 2 * 2 * 2 * 2 = 4 * 4 = 16
r + 16 is your answer.
