This is a trapezoid and the trapezoid formula is b1 plus b2/ 2 times height. 

17 plus 5 is 22. Divided by 2 is 11. 

Now, we have to multiply 11 by the height : 5. 

11 times 5 is 55 and that is your area. 55 units squared.

Ashton designs movie sets. For one scene, he has to hang a banner across an archway that takes the shape of a parabola modeled b
Crazy boy [7]
No question is asked so I'm not sure what you are looking for but below I calculated the point where the two equations intersect:
y - x = 4 → y = x + 4
y = - x² + 6x
x + 4 = - x² + 6x
x² - 5x + 4 = 0
(x - 4)(x - 1) = 0
 x = 4, x = 1

when x = 4, then y = x + 4 = 4 + 4 = 8 → (4,8)
when x = 1, then y = x + 4 = 1 + 4 = 5 → (1,5)

The line and parabola intersect at two points: (4,8) and (1,5)

Seven more than the product of a number and <br> 8<br> is equal to <br> 5
yuradex [85]
8x + 7 = 5

A "product" is the result of a multiplication operation.  So the product of a number, ( which we will call x,) and 8 would be 8x. (Or 8*"x" number) 7 more than that product would be 8x + 7 = 5

Hope that this helps!

a line is perpendicular to y - 5 = -1/4(x + 8) and goes through the point (-1,2). What is the lines y-intercept?
lisabon 2012 [21]

Answer:

y = 4x + 6

Step-by-step explanation:

Turn the equation we are given into slope-intercept form.

y - 5 = -1/4(x + 8)

y - 5 = -1/4x - 2

y = -1/4x + 3

The slope of a perpendicular line is the opposite reciprocal of the original line.

-1/4 -> 4/1 -> 4

Find the new y-intercept using the point given.

y = 4x + b

2 = 4(-1) + b

2 = -4 + b

6 = b

Fill in everything we solved for.

y = 4x + 6

Best of Luck!
