8x-4=2x+35
8x-2x=35+4
6x=39
X=39/6
Answer:
y = -5x - 23
Step-by-step explanation:
Write it in point - slope form:
y - 7 = -5(x + 6)
rearrange:
y - 7 = -5x - 30
y = -5x - 23
Answer:
(0,-2)
Step-by-step explanation:
First we find the equation of the line passes through 
and 
.
The slope of the line is
So by the point slope formula the equation of the line is
When 
we have 
.
Therefore the line joining the two points cuts the y-axis at (0,-2).
Answer:
The width is 8 units
Step-by-step explanation:
This is a variation problem we are to work with.
Length is inversely proportional to width, let length be l and width be w
modeling the statement mathematically, we have lw = k where k is the proportionality constant
Now let’s get k from l = 12 and w = 6
k = 12 * 6 = 72
Now for the second rectangle also;
lw = k given l = 9
9w = 72
w = 72/9
w = 8
