Answer:

Step-by-step explanation:

This is a y=x plot/line shifted by 7 units.

This can also be verified plugging in the values of x=0,y=-7 and x=7,y=0. The only equation which satisfies these points in Equation B. These points have been chosen as they're the intercepts of this plot.

Answer:

-7x+7y=-49

Step by step Explanation:

This can be verified by giving x=0 and y= -7; x=7 and y=0. The second equation only assures this. Therefore the second equation is correct.

A page should have perimeter of 42 inches. The printing area within the page

Tamiku [17]

Overall dimensions of the page in order to maximize the printing area is page should be 11 inches wide and 10 inches long .

<u>Step-by-step explanation:</u>

We have , A page should have perimeter of 42 inches. The printing area within the page would be determined by top and bottom margins of 1 inch from each side, and the left and right margins of 1.5 inches from each side. let's assume width of the page be x inches and its length be y inches So,

Perimeter = 42 inches

⇒ $2(x+y) = 42\\x+y = 21\\y = 21-x$

width of printed area = x-3 & length of printed area = y-2:

area = $length(width)$

$area = (x-3)(y-2)\\area = (x-3)(21-x-2)\\area = (x-3)(19-x)\\area = -x^{2} + 22x -57$

Let's find $\frac{d(area)}{dx}$ :

$\frac{d(area)}{dx}$ = $\frac{d(-x^{2}+22x-57)}{dx} = -2x +22$ , for area to be maximum $\frac{d(area)}{dx}$ = 0

⇒ $-2x+22 = 0\\2x =22\\x=11 inches$

And ,

$y = 21-x\\y = 21-11\\y = 10 inches$

∴ Overall dimensions of the page in order to maximize the printing area is page should be 11 inches wide and 10 inches long .

Solve this please, FIND THE UNKOWN ANGLES WITH STEPS

vazorg [7]

Answer:

A: 70 degrees B: 60 degrees C: 40 degrees D: 65 degrees and 65 degrees E: 60 degrees F: a= 30 degrees

Step-by-step explanation:

To find the missing angle you will have to use the angles that are provided for you so if there is a square in any of the corners that automatically equals 90 degrees, once you add that with the other number degrees just subtract their sum from 180 degrees. BUT if that is not the case and i only gives you on angle that you will just need to use critical thinking to see what is left in the equation and see how it plays out with the angle given and the other angle that you need to find to see if it gives you 180 degrees.
