The answer is to the problem is 120 °
Answer:
x = 12
Step-by-step explanation:
sqrt(x+4) - 3 = 1
First get the sqrt all by itself on one side of the equation. Add 3 to both sides of the equation.
sqrt(x+4) = 1 + 3
sqrt(x+4) = 4
To "fix" the sqrt, that is, "undo it" and get rid of it, you have to SQUARE both sides of the equation.
(sqrt(x+4))^2 = 4^2
x + 4 = 16
subtract 4 to finish up.
x = 12
Check:
sqrt(12 + 4) - 3 = 1
sqrt16 - 3 = 1
4 - 3 = 1
1 = 1 Check!
Answer:
C. 200 minutes, $260
Step-by-step explanation:
The equations would look like this
Lynn = y = 1.10x + 40
Heather = y = 1.15x + 30
Now just plug in.
Lynn
260 = 1.10(200) + 40
260 = 220 + 40
260 = 260
Heather
260 = 1.15(200) + 30
260 = 230 + 30
260 = 260
Hope this helps ya! Keep smiling!
