What is the equation in vertex form of the quadratic function with a vertex at (-1,-4) that goes through (1,8)?

notsponge [240]

Answer:

Step-by-step explanation:

vertex formula = a(x-h)^2 + k

vertex is (h, k) so (-1, -4) means

y = a(x+1)^2-4

passes through (1, 8) so when x = 1 and y = 8

8 = a(1+1)^2-4 = 4a - 4

4a = 4

a = 1

What is four fifths plus eight ninths

Jobisdone [24]

4/5 + 8/9. First we have to find a common denominator for $\frac{4}{5}$ and $\frac{8}{9}$ . $\\ \frac{4*9}{5*9}= \frac{36}{45} \ and \ \frac{8*5}{9*5}= \frac{40}{45} \\$ Now we are going to add: $\frac{36}{45}+ \frac{40}{45}= \frac{76}{45}$ Make $\frac{76}{45}$ a mixed number: $\frac{76}{45}=1 \frac{31}{45}$ So the answer is $\boxed{1 \frac{31}{45}}$
