(f+g)(x) is equivalent to f(x) + g(x)
So that would be (7x-3) + (x²-4x) = x² + 7x - 4x - 3 = x² + 3x - 3
Hope this helps.
Answer:
See below
Step-by-step explanation:
Part 1 -
x: number of hours worked
y: total income
This is written as → y = f(x)
Part 2 -
y = 15*x
Part 3 -
f (35) = 15 × 35 = $525
f (29) 15 × 29 = $435
Week 1 - Ashley worked 35 hours with a total income of $525.
Week 2 - Ashley worked 29 hours with a total income of $435.
I do K12 7th grade and it has really brought my grades up! One thing I have noticed though is the work is more advanced then the work at a normal school. At first I had alot of trouble getting used to the system but after awhile it's very simple. I really like K12 because it let's you learn at your own pace. if you have any questions about K12 I would be happy to answer.
Answer:
- 10x - 11
Step-by-step explanation:
- 3x - 2 - 7x - 9
- 3x - 7x - 2 - 9
= - 10x - 11
hope it helps!
Answer:
Step-by-step explanation:
Calculate the length (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 3) and (x₂, y₂ ) = (0, 7)
d = 
= 
= 
= ≈ 4.1 ( to 1 dec. place )
