17x +x to the second power
14x + 10y = 72
14x + 4y = 96
6y = -24
6 6
y = -4
14x + 10y = 72
14x + 10(-4) = 72
14x - 40 = 72
+ 40 + 40
14x = 112
14 14
x = 8
(x, y) = (8, -4)
Answer: Part A: Group p is called a cluster. Group T is called an outlier.
Part B: it seems that as the hours of exercise increases, their test scores increases.
Step-by-step explanation:
Answer:
-4.67
Step-by-step explanation:
first find f^-1(x)
let f(x)=y
y=3x+2
3x=y-2
x=y-2/3
Therefore f^-1(x)=x-2/3
Now f^-1(-12)=-12-2/3
=-14/3
=-4.67
Answer:
D
Step-by-step explanation:
=
Factor out 2 on the numerator and 2x on the denominator.
=
Cancel the factor (x + 2) on the numerator/ denominator
= ← cancel the 2 on numerator/ denominator
= : x ≠ 0
