You pay $34 for 8 gallons of gasoline and 2 quarts of oil at a gas station. Your friend pays $20 for 5 gallons of the same gasoline and 1 quart of the same oil. Write a system of linear equations that represents this situation. Use x to represent the price of a gallon of gas and y to represent the price of a quart of oil.

Step-by-step explanation:

slope but different y-int 30 they are parallel and have no solution. www . a. Write a system of linear inequalities represented by the graph ...

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
