Answer:
x = -1
Step-by-step explanation:
to find axis of symmetry, use the following equation:
x = -b/2a
in this problem, a = 3, b = 6, c = -12
x = -6/2(3)
x = -6/6
x = -1
Answer:
A. 30
Step-by-step explanation:
The interquartile range for a box and whiskers plot, is the value from the right side of the box minus the value of the left side of the box.
In this case at the far right side of the box it is at 130, at the far left side of the box it is at 100.
130-100=30
Answer:
D
Step-by-step explanation:
Given
- 5x³ + 10x² ← factor out - 5x² from each term
= - 5x²(x - 2) → D
Answer:
a >2
Step-by-step explanation:
n = 3a-6
n must be positive
3a > 6 for n to be positive
Divide by 3
3a/3 > 6/3
a >2
<span>10x+4=7(6x-14)
10x+4=42x-98
-4 -4
10x=42x-102
-42x -42x
-32x=-102
/-32 /-32
x=</span>3.1875
I'm almost positive that this is correct if I multiplied wrong please do it right but this is a more general idea of how to solve it.
