The graph shows equivalent Leah plots a point to show a fourth equivalent ratio. If the y-value of Leah’s point is 36, what is t
denis23 [38]
All you have to do is find the slope of the graph.

1) Pick 2 points: (8,9) and (16,18) for example
2) Use the slope formula (y2-y1)/(x2-x1)
3) Once you know the slope, you know how much the graph will rise for each x-unit. Find the x distance between 24 and the new point (36), and use can calculate how high the y value should be

Does that help?

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. (5 points)
Salsk061 [2.6K]
F(x)=(x-8)/(x+7). g(x)=(-7x-8)/(x-1). Plug in g(x) into f(x), f(g(x))=[(-7x-8)/(x-1)-8]/[-7x-8)/(x-1)+7], which can be simplified as (-7x-8-8x+8)/(-7x-8+7x-7)=-15x/-15=x. Plug in f(x) into g(x), g(f(x))=[-7*(x-8)/(x+7)-8]/[(x-8)/(x+7)-1]=(-7x+56-8x-56)/(x-8-x-7)=-15x/-15=x, as desired.

What is the perimeter of a rectangle with a length of 11.5 yd and a width of 5 yd?
Tems11 [23]
Answer = B - 33yd

Because the perimeter is all the sides added up so you do length + length + width + width = 11.5 + 11.5 + 5 + 5 = 33

Find the discriminant of 3x2 - 10X=-2.
lilavasa [31]

Answer:

76

Step-by-step explanation:

Given a quadratic in standard form : ax² + bx + c : a ≠ 0, then

the discriminant Δ = b² - 4ac

Given

3x² - 10x = - 2 ( add 2 to both sides )

3x² - 10x + 2 = 0 ← in standard form

with a = 3, b = - 10 and c = 2

b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76

I don' need sleep i need answers <br><br> x2+10x= -9<br><br> x2-14x+40=-5
soldier1979 [14.2K]

Answer:

x = -1, -9.

x = 5, 9.

Step-by-step explanation:

x^2 + 10x =  -9

x^2 + 10x + 9 = 0

(x + 1)(x + 9) = 0

x = -1, -9.

x^2 - 14x + 40 = -5

x^2 - 14x + 45 = 0

(x - 5)(x - 9) = 0

x = 5, 9.
