Answer:
73
Step-by-step explanation:
Givens
d = 3
Equation 7d^2 + 10 = ?
Solution
7*3*3 + 10
7*9 + 10
63 + 10 = 73
9y + 2(y + 6) > 5y – 24
Solving for y:
Use distributive property on the left hand side:
9y + 2y + 12 > 5y - 24
Add like terms on the left hand side:
11y + 12 > 5y - 24
Subtract 5y from both sides:
11y + 12 - 5y > 5y - 24 - 5y
6y + 12 > -24
Subtract 12 from both sides:
6y + 12 - 12 > -24 - 12
6y > -36
Divide both sides by 6:
6y/6 > -36/6
y > -6
The solution in interval notation is:
(-6, ∞)
The range is 19-0=19 so therefore your answer is C.
The range is the largest number subtracted by the smallest number.
Answer:
A
Step-by-step explanation:
After the first step, which is to do the inverse by dividing both sides by 4.
The equation will look like x-3=48
You the have to do the second step, which is to add 3 (or do the inverse) on both sides (answer A)
