Answer:
17/12 or 1 and 5/12
Step-by-step explanation:
Answer: Choice B
y = (x+3)^2 - 1
==================================================
Recall that vertex form is y = a(x-h)^2 + k with the vertex being (h,k)
From the given graph, it shows that (h,k) = (-3,1) is the vertex. So we plug this pair of values into the general function above to get
y = a(x-h)^2 + k
y = 1(x-(-3))^2 + (-1)
y = (x+3)^2 - 1
which is the final answer
note: a = 1 is the case for all four answer choices, so we don't have to worry about the value of 'a'
Answer:
x=3.52 y=66.88
Step-by-step explanation:
x+y=70.4
y=19x ---(1)
using (1)
x+19X=70.4
=> 20x= 70.4
x=3.52
y=66.88
