-3s -5=4 what is this problem
Darina [25.2K]
-3s-5=4    First add 5 to both sides of the equal sign to cancel out -5
    +5 +5   You're left with -3s=9

-3s=9        Divide by -3 on both sides. This cancels out the -3s. 9 divided by -3                      equals -3. The answer would be s=-3

Hannah is participating in a marathon. She can run 4 miles in 50 minutes. At this rate, how long will it take Hannah to run 30 m
ra1l [238]
The answer is c


Because if it takes 50 minutes to run 4 miles you need to divide 50/4 and you will get 12.5 and then multiply that by 30 cause she is trying to run 30 miles and that will get you 375 and then divide that by 60 cause their are 60 minutes in a hour and you will get 6.25

F(x)=(5x+1)(4x−8)(x+6)f, left parenthesis, x, right parenthesis, equals, left parenthesis, 5, x, plus, 1, right parenthesis, lef
andrey2020 [161]

Answer:

x=-\frac{1}{5}  \:or \: x=2 \:or\: x=-6

Step-by-step explanation:

Given f(x)=(5x+1)(4x-8)(x+6)

The zeros of the polynomial function are the point where the function f(x) equals zero.

f(x)=(5x+1)(4x-8)(x+6)=0

If abc=0, then a=0 or b=0 or c=0

Therefore:

(5x+1)(4x-8)(x+6)=0 \:means\\5x+1=0 \:or \: 4x-8=0 \:or\: x+6=0\\5x=-1 \:or \: 4x=8 \:or\: x=-6\\x=-\frac{1}{5}  \:or \: x=2 \:or\: x=-6

I WILL MARK YOU BRAINLIEST!!
Butoxors [25]

Answer:

Yes

Step-by-step explanation:

There is a proportional relationship between x and y it's 5.

Think about it when x is 1 y is 5

When x is 2 y is 10

When x is 5 y is 25

When x is 7 y is 35

To get this for this question all you have to do is multiply x by 5 to get y.

That's how you know it's proportional.

Hope this helps!!!
