Answer:
D. ax-b<-c or ax-b>c is the correct answer.
Step-by-step explanation:
Answer:
It will take 21 years.
Step-by-step explanation:
First, find what x would be for it to equal 40 feet. This can be done with the equation 4.5 + 1.75x = 40.
4.5 + 1.75x = 40
Subtract 4.5 from both sides. This cancels out the +4.5.
1.75x = 40 - 4.5
Subtract 4.5 from 40 to get 35.5.
1.75x = 35.5
Divide both sides by 1.75. This cancels out the *1.75.
x = 35.5/1.75
Expand 35.5/1.75 by multiply both the numerator and denominator by 100.
x = 3550/175
Reduce 3550/175 by canceling out 25.
x = 142/7 = 20 2/7
Go up by one from 20 to get the answer of 21 years.
They are complementary because they add up to a 90 degree angle
Answer: h(-9)=4*(-9)-2=-36-2=-38
-38 is ur answer
xy - -4x²
Step-by-step explanation:
(2x - 3y)(4x -y)
2x( 4x -y) -3x( 4x - y)
8x² - 2xy - 12x² + 3xy
8x²- 12x²- 2xy + 3xy
-4x² + xy
xy - -4x²
