A. 7*4
because there are no parentheses or exponents so multiplication is next
The answer is -3. I just did it on a calculator
For this you have to get r by itself so you put 1 over 3 and move it to the other side and then you get 2/3 as an answer
Answer:
Axis of symmetry= 3
Step-by-step explanation:
f(x)= 2x^2 +12x-4
f(x)=ax^2+bx+c
x=12/2(2)
x=3
f(x)= 2(3)^2+12(3)-14
f(x)= 2(9)+36-14
f(x)=18+36-14
f(x)= 54-14
y=40
