Answer:

y = 1/7x -1

Step-by-step explanation:

1) Find the slope.

- In this case, the equation given is in simplest form so you can easily come to the conclusion that '-7' is the slope. But, since the math question wants a slope-intercept form in perpendicular form, the slope would actually be 1/7.

2) Use the point-slope form and substitute the values available. Then solve.

m (slope) = 1/7

(a, b) = (14, 1)

y - b = m(x - a)

y - 1 = 1/7(x - 14)

y - 1 = 1/7x - 2

y = 1/7x - 1

The result is your answer.

Hope this helped (please tell me if I made a mistake or if you have any confusion and I will resolve it under the comments) ^^

Can someone help me please

Llana [10]

Answer:

8: 50 hours

9: 6 inches

10: 43 cm

Step-by-step explanation:

I couldn't see the entirety of 7 because some of the page was folded, so I didn't answer it.

8: Make them equations of y=12x+450 and y=21x. Since both equal y, set them equal to each other so 21x=12x+450. Subtract 12x from both sides to get 9x=450. Divide by 9 on both sides to get 50.

9: The length equals 3w-6 and the width is just w. The perimeter would equal 2w+2(3w-6) which when factored is 2w+6w-12. Simplify to 8w-12. If P=8w-12 and we know P=36, then set the two equations equal to each other so that 8w-12=36. Add 12 to both sides to get 8w=48. Then divide both sides by 8 to get a final answer of w=6.

10. P=x+5x+8+4x-7. Simplify that to P=10x+1. We know that P=71, so set the two equations equal to each other to get 71=10x+1. Subtract 1 from both sides to get 70=10x. Divide both sides by 10 and x=7. Now substitute x in each side of the triangle and we get 7, (4*7-7), and (5*7+8). Solve all of those to get sides of 7, 21, and 43. The question asks what is the length of the longest side, so the answer would be 43.

Crazy boy [7]

Answer:

x = 40

Step-by-step explanation:

Since FG and HI are parallel and BC is a transversal, then

∠ GBE and ∠ GBE are same side interior angles and are supplementary, thus

3x + 20 + x = 180, that is

4x + 20 = 180 ( subtract 20 from both sides )

4x = 160 ( divide both sides by 4 )

x = 40
