write the slope-intercept form of the line that passes through the point (1,0) and is parallel to x-y=7. type your answer in the
Brilliant_brown [7]
  • Parallel lines have the same slope but different y intercepts.
  • turn x-y=7 into slope intercept form by isolating y which would be -y=-x+7
  • divide the equation by -1 in order to make y positive and you get y=x-7
  • So rewrite the equation with the same slope but this time solving for b
  • y=x+b
  • plug in your coordinates
  • 0=1+b
  • subtract 1 from both sides
  • -1=b
  • so your equation would be
  • y=x-1

HELP PLEASE SHOW STEPS I HAVE NO IDEA WHAT TO DO. I HAVE BEEN TRYING TO FIGURE IT OUT BUT I CAN’T.
weqwewe [10]

Answer: x^{2} +23x+49

Step-by-step explanation:

To find the area of the shaded region, you must find the area of the larger rectangle [(x+10)×(2x+5)] and subtract the area of the smaller rectangle [(x+1)×(x+1)] from it.

First, you simplify the larger rectangle's area:

(x+10)×(2x+5) = 2x^{2} +25x+50

Then, simplify the smaller rectangle's area:

(x+1)×(x+1) = x^{2} +2x+1

Finally, subtract the smaller rectangle's area from the larger rectangle's area:

(2x^{2} +25x+50) - (x^{2} +2x+1) = x^{2} +23x+49

Therefore, the final answer is x^{2} +23x+49.

I hope this helps!

Question #7
Sever21 [200]

Answer:

The area is 56.7 square inches

Step-by-step explanation:

Given

See attachment for corner shelf

Required

The area

The corner shelf is a quadrant with radius;

r = 8.5in

The area of a quadrant is:

Area = \frac{\pi r^2}{4}

So, the area of the corner shelf is:

Area = \frac{\pi * 8.5^2}{4}

Area = \frac{\pi * 72.25}{4}

Area = \pi * 18.0625

Take \pi as 3.14

Area = 3.14 * 18.0625

Area = 56.7 -- approximated
