Hello,
y+9=(x-10)*(-2)
==>y=-2x+11
Answer D if you put an "+" betheen y and 9 !!!!!!
Answer:
(-2.2, -1.6), (3, 1)
Step-by-step explanation:
You don't have to go far to find the equations. They are right there in your problem statement. Perhaps you want to find the solutions to the equations.
Use the first equation to write an expression for x, then substitute that into the second equation:
x = 2y +1
y^2 -3(2y+1)(y) +8 = 0
-5y^2 -3y +8 = 0
-(5y +8)(y -1) = 0
y = -8/5 or y = 1
The corresponding values of x are ...
x = 2(-8/5)+1 = -11/5
x = 2(1) +1 = 3
The solutions are (x, y) = (-2.2, -1.6) and (3, 1).
It would be e, because it went down 10 instead of 5

Answer: 70.00$
Step-by-step explanation:
The question states that it takes 20 gallons of gas to get there, and the cost of three gallons of gasoline is $10.50.
so
20/3 * 10.50=70$
