Answer:
69
Step-by-step explanation:
to find f(3), we'll have to substitute x with 3
therefore,
f(3) = 19 × 3 + 12
= 57 + 12
= 69
Answer:
- -28y^4 - 7y^3 + 62y^2 + 5y - 30
Step-by-step explanation:
<u>Opening the parenthesis and simplifying by combining like terms:</u>
- (6 - y - 4y^2)(-5 + 7y^2) =
- 6(-5) +6(7y^2) - y(-5) -y(7y^2) -4y^2(-5) -4y^2(7y^2) =
- -30 + 42y^2 + 5y - 7y^3 +20y^2 -28y^4 =
- -28y^4 - 7y^3 + 62y^2 + 5y - 30
Answer:
x = 47
2x+6 = 100 which is the angle measure
Step-by-step explanation:
The angles are vertical and vertical angles are equal
2x+6 = 100
Subtract 6 from each side
2x+6-6 =100-6
2x = 94
Divide by 2
2x/2 = 94/2
x =47
Now to find the measure of 2x+6
We know that it is equal to 100
so 2x+6 = 100
