Answer:
E
Step-by-step explanation:
1+2+2+1
Answer:
2(3x+y=4)
1(x+2y=-2)
6x+2y=8
<u>(-) x+2y=-2</u>
<u>5x=10</u>
5
x=2
x+2y=-1
2+2y=-1
<u>-</u><u>2</u><u> -</u><u>2</u>
<u>2y=-</u><u>3</u>
2
y=-3/2
Step-by-step explanation:
- multiply the first equation by 2 to make y equal to each other.
- subtract to eliminate y
- divide by 5 to get x
- take one of the equations
- replace x by 2 to solve for y
Y = 1/3x + 3....slope is 1/3. A parallel line will have the same slope.
y = mx + b
slope(m) = 1/3
(2,0)...x = 2 and y = 0
now we sub and find b, the y int
0 = 1/3(2) + b
0 = 2/3 + b
-2/3 = b
so ur parallel equation is : y = 1/3x - 2/3
Answer:
13 years old
Step-by-step explanation:
2x - 4
11-5=6
6 x 2 = 12
12 - 4 = 8
8 + 5 = 13
CHECKING JUST TO MAKE SURE:
13 - 5 = 8
11 - 5 = 6
6 x 2 = 12
12 - 8 = 4
You can now tell that it is correct.

thus, the best car is car B,because it can tavel 29 miles with only one gallon,andcar A can only travel 28 miles with one gallon.
