Answer:
The car would be worth 1200.
Step-by-step explanation:
Okay, the way to solve this type of question is quite simple,
you would start with the amount is lost per year being $325 a year, then multiply that by the 4 years grandpa waited and then subtract the overall amount lost in worth of the car from the original price and you got your answer.
The math: 2500-(325*4)=1200
Answer:
a. (-∞, ∞)
b. (-∞, 4]
c. (-4,0) and (4,0)
d. (0, 1)
e. x = -∞ to x = 2, x = 0 to x = 3
f. x = x = 2 to x = 0, x = 3 to x = ∞
g. relative maximum at points (-2, 4) and (3, 2)
h. relative maximum of f is 4. There is an other relative maximum at xf = 2
f.

Answer:
C. 10
Step-by-step explanation:
Let x and y represent push-ups and pull-ups, respectively.
x + y = 24 . . . . . . combined total of push/pull-ups
2x +4y = 68 . . . . time required for the exercise
We can divide the second equation by 2 and subtract the first:
(1/2)(2x +4y) -(x +y) = (1/2)(68) -(24)
x +2y -x -y = 34 -24 . . . . . eliminate parentheses
y = 10 . . . . . . . . . simplify
Malia did 10 pull-ups.

She did 14 push-ups.
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
You know:
m = 2 So substitute/plug it into the equation
y = mx + b
y = 2x + b To find b, plug in the point (1, 3) into the equation, then isolate/get the variable "b" by itself in the equation
3 = 2(1) + b Subtract 2 on both sides to get "b" by itself
3 - 2 = 2 - 2 + b
1 = b
y = 2x + 1
