Answer:
B. 3x^2 - 2x - 1.
Step-by-step explanation:
(f + g)x = f(x) + g(x)
= -4x + 3 + 3x^2 + 2x - 4
Adding like terms we get the answer:
= 3x^2 - 2x - 1.
Answer:
y=-2x+3
Step-by-step explanation:
Slope intercept form is y = mx + b where m is the slope, b is the y-intercept, and y and x are their respective coordinates.
The questions gives us a coordinate pair and a slope so all we need to find is the y-intercept to find the equation.
Begin by plugging in what we know.
(3) = (-2)(0) + b
3 = 0 + b
3 = b
Plug in the y-intercept (b) and slope (m)
y=-2x+3
Answer:
25 rounds
Step-by-step explanation:
Let
x -----> the number of rounds of golf
y ---> total charges to play
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
<em>Membership</em>
----> equation A
The slope is m=$35 per round
The y-intercept b=$500 (annual membership fee)
<em>Non-Membership</em>
----> equation B
The slope is m=$55 per round
The y-intercept b=$0
Equate equation A and equation B

solve for x



For x=25 rounds the cost to be the same with and without a membership
Yes because it is a linear equation
