Answer:
$88 in total
Step-by-step explanation:
x = number of hours
y = total cost to rent the snowboard.
$25 is already guaranteed
25 + 15.75x = y
since it is 4 hours from 8:30 a.m. to 12:30 a.m. you put 4 into x.
25+15.75(4) = y
88 = y
Answer:
x = 1 y = -4
Step-by-step explanation:
- Plug the value of y into the other equation.
x + 3y = -11
x + 3(-4x) = -11
x - 12x = -11
-11x = -11
x = 1
- Now substitute the value of x into any equation.
y = -4x
y = -4(1)
y = -4
The anwser would be -15
3 x (-5) = -15
Answer:

Step-by-step explanation:
Given




Required
Find x
The area is calculated as thus:

Substitute values




Multiply through by 2


Remove absolute sign

Add 6 to both sides

Divide by 3


<em>So, the coordinates are (-8, 11) or (12,11)</em>
