5. Write x^2 + 8x = -4y - 8 in standard form. Identify the vertex, focus, axis
1 answer:
Answer:
The answer to your question is:
Step-by-step explanation:
Data
x² + 8x = -4y - 8
x² + 8x + 16 = -4y - 8 + 16
x² + 8x + 16 = -4y + 8
(x + 4)² = -4(y - 2)
(x + 4)² = 4(-1)(y - 2)
Vertex = (-4, 2)
p = 1
Focus = (-4, 1)
Axis of symmetry x = -4
Directrix y = 3

The image is sideways.
But if your graph is like on the image, then the answer is: {y│-3 ≤ y ≤ 4}
Range is the set of y values
Least function value is -3 and greatest is 4

Answer:
18
Step-by-step explanation:
y=mx + b
m is the slope.
Therefore, 18 should be the slope
Answer: x=-5 or x=2
Step-by-step explanation:
x^2+3x-10=0
x^2+5x-2x-10=0
x(x+5)-2(x+5)=0
(x+5)(x-2)=0
x+5=0 or x-2=0
x=-5 or x=2
