Answer:
2x^2 + 4x+2
Step-by-step explanation:
f(x) = 2x^2 + x and g(x) = 3x + 2
f(x) + g(x) = 2x^2 + x + 3x + 2
Combine like terms
= 2x^2 + 4x+2
Answer:
The total cost of the petrol is 2.075 cents.
Step-by-step explanation:
The cost of per gallon petrol = 0.83
Drive per gallon = 8 miles
Here, total distance traveled = 20 miles.
So, the total petrol used for 20 miles = (20 / 8) gallons
= 2.5 gallons
Now, cost of petrol per gallon = 0.83 cents
So, total cost of petrol = 0.83 x 2.5 = 2.075 cents
Hence, the total cost of the petrol is 2.075 cents.
Answer:
f ( - 2 ) = - 12
Step-by-step explanation:
f ( - 2 ) = - 3 ( -2 )^2
then you do the exponent first so
- 3 ( 4 )
now you multpily the - 3 and 4
you get - 12
Answer:
(3, 1)
Step-by-step explanation:
Let the coordinates of B be (x, y)
Since, M is the midpoint of AB.
Therefore, by mid point formula:
You can take two of the x and y on the table to find the slope:
y2 - y1 / x2 - x1
Lets use (3, 12) and (4, 15)
15 - 12 / 4 - 3
3/1
The slope is 3
Now you can use the point-slope formula to find the equation: y - y1 = m(x - x1)
y - 9 = 3(x - 2)
y - 9 = 3x -6
y = 3x + 3
So you are correct with choice B.
