Answer:
x + y = 41
x - y = 13
------------------
2x = 54..............We divide 2 such that
x = 27
Then we plug 27 into the equation such that
27 + y = 54.................Subtract 27 to get
y = 14

4 because you’re finding sizes for multiple people while the other questions are just asking for one thing
Use the linear slope formula to solve for m:
m=(y2-y1)/(x2-x1)
using the points (-1,1) and (1,5) you can find the slope for the first interval:
m=(5-1)/(1-(-1))
m=4/2
m=2
you can double check by using the same formula on the second interval, which is (1,5) to (3,9).
m=(9-5)/(3-1)
m=4/2
m=2
therefore, the rate of change is 2.
Answer:
3
Step-by-step explanation:
Hello! I'm guessing you need someone to solve this equation!
4(5x-6)=2(8x+10)
20x-24=16x+20
Add 24 on both sides!
20x=16x+44
Subtract 16x on both sides!
4x=44
Divide 4 by 44
x=11
