Answer:
A) (2,20)
B) Yes, Because the line passes through the origin (0,0)
C.) In 10 hours, the cost of electricity is $100
D.) y=10x
Simplify the equation
f(x) = 2x + 8 - 8
f(x) = 2x
Now substitute the x values
f(24) = 2(24) = 48
f(8) = 2(8) = 16
f(2) = 2(2) = 4
f(-2) = 2(-2) = -4
The correct answer is 4. (-2,-4)
Answer:
$105
Step-by-step explanation:
assuming that it costs $35 dollars for renting 1 kayak per day:
3 * 35 = k 3 is for the # of kayaks and 35 is the cost
105 = k multiply 35 w/ 3 to get the answer
X - 2y = - 9
7x + 2y = 1
x - 2y = - 9
(+)
7x + 2y = 1
___________
8x = - 8
x = - 1
- 1 - 2y = - 9
2y = 8
y = 4
