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?
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.
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
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
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.
