4 0

$5x-5(6\cdot7x)=65\\\\5x-5(42x)=65\\\\5x-210x=65\\\\-205x=65\qquad\text{divide both sides by (-205)}\\\\x=-\dfrac{65}{205}\\\\x=-\dfrac{65:5}{205:5}\\\\\boxed{x=-\dfrac{13}{41}}$

If a graph of y=-4x +2 were changed to a graph of y=-4x+5, how would the y- intercept change?

Dmitry [639]

Answer:

So if y=-4x+2 was changed to y=-4x+5, then the y-intercept would increase by 3.

The y-intercept was (0,2) then it becomes (0,5) in the new line.

Step-by-step explanation:

The slope-intercept form a line is y=mx+b where m is the slope and the y-intercept is b.

Both of these equations given are in this form.

y=-4x+2 when compared to y=mx+b you see that m=-4 and b=2.

Since b=2 then the y-intercept is 2.

y=-4x+5 when compared to y=mx+b you see that m=-4 and b=5.

Since b=5 then the y-intercept is 5.

So if y=-4x+2 was changed to y=-4x+5, then the y-intercept would increase by 3.

The output with the y being -4

For this case we have a function of the form $y = f (x)$ , where $f (x) = - 4x$ . We must find the values of "and" according to the following function: $y = -4x$
