Answer:
D. x > -4 or x < -8
Step-by-step explanation:
5.2 is the y-intercept of the regression line 5.2 + 13.5x
Answer:
∠1 = 51° ∠2 = 39°
Step-by-step explanation:
ok since the picture is a right angle put it equal to 90
like this:
3x + x + 22 =90
4x + 22 = 90
4x = 68
x = 17
now we plug it in:
3(17)= 51°
(17) + 22 = 39°
*a straight line is equal to 180, a right angle is 90
does that make sense?
Answer: f(x) = -3 if -4 ≤ x ≤ -1
Explanation: The filled in circles mean that solution is possible, so you use the equal to sign.
Hope this helps!
