Answer:
y = -1 x = 4
Step-by-step explanation:
(X+3y=1) 5 Multiply this equation by 5 to cancel out the x
-5x+4y=-24
-5x + 4y= -24
+ 5x + 15y = 5 Add both equations together
19y = -19 Divide both sides by 19
y = -1
Plug -1 for y into one of the equations
x + 3(-1) = 1 Multiply 3(-1)
x - 3 = 1
+ 3 + 3 Add 3 to both sides
x = 4

Answer:
B
Step-by-step explanation:
2x = log3 (y - 1)
y - 1 = 3^2x
y = 3^2x + 1
(x - h)^2 + (y - k)^2 = r^2
h = -2
k = -2
r = 6
(x - (-2))^2 + (y - (-2))^2 = 6^2
(x + 2)^2 + (y + 2)^2 = 6^2
(x + 2)^2 + (y + 2)^2 = 36. your answer
hope this helped, blessings! :)
So, 27=30 and 18=20 rounded
so what you would do now is multiply 30 x 20 and you get $600
1 gallon ...........23 miles
59 gallons..........x miles
x=23*59=1357 miles
