Answer:
I believe the answer is y = -7/3x
Step-by-step explanation:
When you rearrange the equation, y = -3x - 8y, you will get -7y = -3x.
We want the equation to be equal to y by itself. So we divide -7 from both sides, giving us the equation y = 3/7x.
The graph that is perpendicular to y = 3/7x is it's reciprocal: y = -7/3x
Answer:
B= (-1,-4)
Step-by-step explanation:
Answer: See explanation
Step-by-step explanation:
a. 19 > x + 4
Collect like terms
= 19 - 4 > x
= 15 > x
= x < 15
b. 5x > 4x - 9
Collect like terms
5x - 4x> -9
x > -9
The median is 4.5 becuase it's in between 4 and 8 so 4.5 my teacher taught me that

Answer: (4, 7)</h3>
============================================================
Explanation:
Compare the given equation to the vertex form y = a(x-h)^2 + k
You'll see that a = 3, h = 4 and k = 7
The vertex is (h,k) = (4,7)
The value of 'a' determines if the parabola opens upward or downward. Since a > 0, it opens upward. This furthermore leads to the vertex being the lowest point on the parabola.
The value of 'a' also determines how vertically stretched or compressed the parabola is.
