Answer:

AB = 55.25

Step-by-step explanation:

Set up an equation where the length of AB is equal to AC minus BC. This will allow us to solve for x, and then the length of AB.

AB = AC - BC

5x + 9 = 87 - (3x + 4)

5x + 9 = 87 - 3x - 4

5x + 9 = 83 - 3x

8x + 9 = 83

8x = 74

x = 9.25

Now plug  9.25 in for x in the equation for AB

AB = 5x + 9

AB = 5(9.25) + 9

AB = 46.25 + 9

AB = 55.25

Answer:

The box to the left will have the equation p(x) = 5x² and the box to the right will have the equation n(x) = \frac{1}{5} x^{2}

Step-by-step explanation:

The coefficient of the x² decides how wide or narrow a quadratic graph is. If the coefficient is a fraction of 1, the smaller the fraction the wider the graph gets. If the coefficient is a number bigger than 1, the bigger the number, the narrower the graph gets.

To find the distance b/t 2 points you need to use the distance formula. that is

distance = square root of (x2-x1)^2 + (y2-y1)^2


to fill it in, it is

(it doesnt matter which point you start with, as long as its consistent)

x1 = 9
x2 = 5
y1 = -8
y2 = -10

square root of (5-9)^2 + (-10-8)^2

lets do algebra!

square root of (-4)^2 + (-18)^2

square root of 16 + 324

square root of 340


Distance = 18.4391 units.

I hope this helps!
