Answer:
The vertex is ( -4,1)
Step-by-step explanation:
The equation for a parabola can be written as
y = a( x-h)^2 +k where ( h,k) is the vertex
y = 2
(x + 4)² + 1
Rewriting
y = 2
(x - -4)² + 1
The vertex is ( -4,1)
Answer:
C
Step-by-step explanation:
given
x + 19 ≤ - 5 ( isolate x by subtracting 19 from both sides )
x ≤ - 24 → C
Answer:
Commutative property of multiplication
Step-by-step explanation:
Commutative property of multiplication basically means that the order in which you multiply numbers does not matter.
For exampe:
3 x 4 = 4 x 3
12 = 12
In your case:
5 x 7 x 4 = 5 x 4 x 7
140 = 140
If we break that down:
5 x 7 x 4 = 5 x 4 x 7
35 x 4 = 20 x 7
140 = 140
9514 1404 393
Answer:
1. proportional, 6
2. not proportional
Step-by-step explanation:
<u>Table 1</u>
Each y-value is 6 times the corresponding x-value, so the variables are proportional, and y = 6 times x.
<u>Table 2</u>
The ratios of y to x are 2, 4, 8, so are not the same. The values are not proportional.
