X=number of miles
stars cost is 35+price for driving
price for driving=cost per mile times number oof miles
starts=35+0.25x
express is 17+0.4x
when will prices be equal?
set eaqual to each other
35+0.25x=17+0.4x
subtract 0.25x from both sides
35=17+0.15x
subtract 17 from both sides
18=0.15x
divide both sides by 0.15
120=x
answer is 120 miles
answer is D
The goal is to get the inequality into the form Ax+By > C or Ax+By < C
First multiply both sides of the inequality by 2 to clear out the fractions
y > (3/2)x - 7/2
2*y > 2*( (3/2)x - 7/2 )
2y > 2*( (3/2)x ) + 2*( -7/2 )
2y > 3x - 7
Now get the x and y terms to one side; move the 7 to its own side
2y > 3x - 7
2y+7 > 3x - 7+7 ... add 7 to both sides
2y+7 > 3x
2y+7-2y > 3x-2y ... subtract 2y from both sides
7 > 3x-2y
3x-2y < 7 ... flip the two sides and the inequality sign
We finally have the inequality into the form Ax+By < C where
A = 3
B = -2
C = 7
---------------------------------------------
The answer is 3x-2y < 7
Answer:
Step-by-step explanation:
-6x + y = 4
<u>6x - 2y = -2 </u>+
-y = 2
y = -2
.
Substitute the value of y to the one of equations
6x - 2y = -2
6x -2(-2) = -2
6x + 4 = -2
6x = -2 - 4
6x = -6
x = -1
