Answer: 5/4x
Step-by-step explanation:
To solve this you'll need to use the slope formula which is
Y2 - Y1 over
X1 - X2
You already have two points so that's what we'll use.
(4, 7) (12, 17)
17 - 7
12 - 4 = 10/8
10/8 can be simplified further to 5/4
Answer:
Draining rate is at 1.5 gallons per minute
That would be y = 1.5g / x.
From the function or the equation, here is the answer.
The range would be all real numbers such that 0 ≤ y ≤ 40.
Step-by-step explanation:
Answer:
a. x=-5
Step-by-step explanation:
|10x + 50| = 0
10x + 50 = 0
10x=-50
x=-5
really need brainliest!
First multiply both sides by 7
Your equation now looks like this:
x-28=0
Now move the constant to the other side causing it to change signs
The negative now becomes a positive
x=28
Now you are left with your answer:
x=28
Hope this helps! :3
Answer:
( -
, - 3)
Step-by-step explanation:
Given
19x = 15y and (x, - 3 ), that is y = - 3
Substitute y = - 3 into the equation
19x = 15(- 3) = - 45 ( divide both sides by 19 )
x = -
