Answer:
The vertex of this equation is (2, -7)
Step-by-step explanation:
In order to find the vertex of this equation we start with the base form of the vertex form.
y = a(x - h) + k
With this equation (h, k) is the vertex. You can see that 2 lines up with h and -7 lines up with k. This shows that (2, -7) is the vertex.
Answer:
the slope should be 5
Step-by-step explanation:
y = 5x - 10
Answer:
44
Step-by-step explanation:
f(x) = -7x + 5x^2 + 10
f(-2) = -7(-2) + 5(-2)^2 + 10
= 14 + 20 + 10
= 44
Answer:
-4, 2, 3
Step-by-step explanation:
Centre: (-4,2)
Radius: 3
(x - h)² + (y - k)² = r²
(x - -4)² + (y - 2)² = 3²
(x + 4)² + (y - 2)² = 9
Answer:30
Step-by-step explanation:6 times 4 is24 and to the nearest 100 it will be 30
