Answer:
x = 1, y = -2
Step-by-step explanation:
- 2x + 10y = -22 _______(1)
-2x - 4y = 6 _______(2)
From (1),
10y + 22 = 2x
x = (10y + 22) / 2
x = 5y + 11 .______(3)
Substitute (3) into (2),
-2 ( 5y + 11) -4y = 6
-10y - 22 - 4y = 6
-14y = 6 + 22
-14y = 28
y = 28/ -14
y =-2
Substitute y = -2 into (3).
x = 5y + 11
x = 5(-2) + 11
x = -10 + 11
x = 1
Therefore, the solution is x = 1, y = -2.

Answer:
6
Step-by-step explanation:
We need to find the slope
We have 2 points
(0,0) and (1,6)
m = (y2-y1)/(x2-x1)
= (6-0)/(1-0)
= 6/1
= 6
y = 6x
The constant of proportionality is 6
Answer:Yes, he is correct
Step-by-step explanation:Plug 6 in as your x-value in the equation y=-275x+3500 and you will get y=1850
multiply the 2 numbers
9 1/2 * 1 3/4 =
19/2 * 7/4 = 133/8 = 16 5/8 miles
