The x intercept is 2

<span>x = -5 - 2y.

</span>Because when you subtract 4y from both sides you end up with 2x = -10 - 4y. After that you divide both sides by 2 and get the answer x = -5 - 2y.

(This might be the answer and also, I might have not completely done it or something. But I'm pretty sure I did most of it right.)

Y=-4x-41 that passes through (-2,7)
dalvyx [7]

Answer:

Parallel: y=-4x-1

Perpendicular: y=-4x+13/2

Step-by-step explanation:

For the equation y=-4x-41, the slope is -4. Writing a line related to this equation has two options:

  • If the line will be parallel to it then this is the slope of the new line as well. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y-7)=-4(x--2)


y-7=-4x-8


y=-4x-1

  • If the line will be perpendicular to it then the slope is the negative reciprocal of the previous slope. It is 1/4.

(y-7)=1/4(x--2)


y-7=1/4x-1/2


y=-4x+13/2

If three pounds of coffee costs $22.56, what is the cost of 1
NeX [460]

Answer:

$7.52 = 7 dollars and 52 cents.

Step-by-step explanation:

Given that three pounds of coffee = $22.56

1 pound of coffee = $22.56/3

Thus, we would have:

\frac{22.56}{3} = 7.52.

A pound of coffee = $7.52

$7.52 = 7 dollars and 52 cents.
