Answer:
x=3, y=5
Step-by-step explanation:
To find x:
Because opposite sides of a parallelogram are congruent, we can set up the equation 2x+5=12x-25. Solving the equation will show that x=3.
To find y:
Using the same method as x, we can find that y=5.
Hope this helped!
Answer:
The x intercept is (7/5,0)
Step-by-step explanation:
y=−5x+7
To find the x intercept, set y=0 and solve for x
0 = -5x+7
Subtract 7 from each side
0-7 = -5x+7-7
-7 = -5x
divide each side by -5
-7/-5 = -5x/-5
7/5 =x
The x intercept is (7/5,0)
Ok so t=1.95p for each cost of pound
