F(x)=-3.25x +22.41
f(-4.2)= 3.25(-4.2)+22.41 = 8.76
Let’s make an equation 5x=15.25. We should get x by itself by dividing both sides by 5. Which should leave x=3.5, which would mean he’d have to run faster, so no. It’s not reasonable
Answer:
21:24
Step-by-step explanation:
7:8 is your ratio
so if _:24 is equivalent, you have to figure out what 24 is divisible by to equal 8
8×3=24
so now we have to multiply 7 by 3
7×3=21
so your answer is 21:24 = 7:8
hope this helps :)
The value of x=8 because that symbol between the 2 two's is cubed so that means 2x2x2=8
Just to look unnecessarily neat
2
x
2 Because when the the symbol "cubed" is involved it will be
x multiplied 2x over itself as you would do to find the area of
2 A cube
_
8
