Which is not labeled correctly
X^2+34=74
minus 34 from both sides
x^2=40
sqrt both sides
x=+/-√40
x=+/-2√10
the values 2√10 and -2√10 are soltuions for x
Step-by-step explanation:
all the equations x could be perpendicular to the equation y.
so, the anawer :
B. x = 8
D. x = -2
Step-by-step explanation:
a) The total cost C is given by

b) If the total cost is $400, then we can solve for the number of hours as

Solving for n, we get

Answer:
y = 3x = 1
Step-by-step explanation:
