Step-by-step explanation:
$7.20 divided by 3.
<u>Answer:</u>
x = -4
<u>Step-by-step explanation:</u>
We are given the following word problem which we can solve by breaking it down into parts and translating it into numerical values:
Fourteen more than three times a number is 2.
1. Fourteen more than ---> + 14
2. three times a number ---> 3x (assuming the number to be x)
3. is 2 ---> = 2
So combining these, we get:
3x + 14 = 2
Solving this to get:
3x = 2 - 14
3x = -12
x = -12/3
x = -4
Answer:
x = 2/5
Step-by-step explanation:
Given:
7 + 5x = 3(y-2)
Rearrange this equation such that x is expressed in terms of y
7 + 5x = 3(y-2) (expand right side)
7 + 5x = y(3)-2(3)
7 + 5x = 3y-6 (subtract 7 from both sides)
5x = 3y - 6 - 7
5x = 3y - 13
we are given the y-value of the coordinate pair (? , 5)
simply substitute y=5 into the equation above
5x = 3y - 13
5x = 3(5) - 13
5x = 15 - 13
5x = 2 (divide both sides 5)
x = 2/5
Answer:
The Answer is: y = - 2x + 8.
the y-intersept is 8, and the slope is -2x
