<em>The vertex for f(x) = 1/2 x2 + 3x +3/2 is:</em>
<u><em>(-3,-3)</em></u>
It hard for me too but I think I got it
Answer:
D
Step-by-step explanation:
The sum of supplementary angles is 180°
To find the supplement of 60° subtract it from 180°, that is
second angle = 180° - 60° = 120° → D
Answer: l = P/2 - w
Step-by-step explanation:
Perimeter formula for rectangle :
P = 2( l + w )
We have to write l in terms of P and W.
P/2 = ( l + w)
P/2 - w = l
Now, flip the equation and you'll get :
l = P/2 - w
Answer: 2-(2x+40) or (2x+40)-2
Step-by-step explanation: If you wanted to solve the problem, you have to do the stuff in the parentheses before you do the stuff out of the parentheses. In the parentheses, you will have to solve 2x before you do anything else. When you solve 2x, the answer to that, add it to 40. Then the answer in the parentheses, subtract it by 2 and you can get the answer.
