Answer:
Incorrect.
Step-by-step explanation:
6 + x = 19
Plug in when x = 12
6 + 12 = 19
18 = 19
It is incorrect, so 12 is not a solution.
Answer: D
<u>Step-by-step explanation:</u>
Vertex form is: f(x) = a(x - h)² + k where (h, k) is the vertex.
f(x) = (x - 3)² - 5
- the vertex is (3, 5).
- "a" is positive (+1), so it points upward.
The only graph that matches is the last one, <em>which I called graph D.</em>
Step 1 because looking at PEMDAS he multiples the 4 and 2 before the 2 and the exponent.
SinA /a = sin C / c
sin 60/9 = sin C / 10
(√3/2)/9 = sinC/ 10
√3/18 = sin C / 10
so c will be sin inverse ((10√3)/10)
