Answer:
x=-50
Step-by-step explanation:
31/25x=-62
x=-62/(31/25)
x=(-62/1)(25/31)
x=--1550/31
x=-50
Answer:
The table represents a function.
What is the value of f(-1)?
f(-1) = - 3
f(-1) = -1
f(-1) = 0
f(-1) = 6
Step-by-step explanation:
Answer: a = 23 ft.
Reasoning:
The question asks for the value of the leg a, given the tangent of the opposite angle and the length of the adjacent-leg, b.
The ratio that relates the three parameters is:
tan(A) = opposite-leg / adjacent-leg = a / b = a / 23 ft
Solve for a, wich is the unknown:
a = 23ft * tan(A) = 23ft * 1.0 = 23 ft
Answer: 23 ft.
Point- Slope form is
y - y1 = m (x - x1)
m = slope, (x1, y1) = point
Slope intercept form is y = mx + b
m = slope, b = y-intercept
In order for two lines to be parallel, they must have the same slope, so in this case our slope, m = 2. Now use point-slope form to insert the point and solve.
y--2 = 2 (x --5)
y + 2 = 2x + 10
y = 2x + 8
