Set the equations equal to each other since the x will be the same. Get like terms on the same side and solve.
2x-5=-2/3x+3
2x-5+5=-2/3x+3+5
2x=-2/3x+8
2x+2/3x=-2/3x+2/3x+8
2 2/3x=8
8/3x=8
(3/8)8/3x=8(3/8)
x=3
x=3
Answer:
y = 2/5x - 3
Step-by-step explanation:
Rearrange the equation to get y by itself.
5y = 2x + 5
y = 2/5x + 1
Using y = mx + b and knowing that parallel lines have the same slope plug in the coordinate points given.
-1 = 2/5(5) + b
-1 = 2 + b
b = -3
y = 2/5x - 3
Answer:
a) He substituted 0.8 instead of 0.08.
b) $264
Step-by-step explanation:
- The full question is: a. What did Peter do incorrectly? b. What is the correct amount of interest?
- Using the equation
, we can substitute the given values. - I = 275 x 0.08 x 12
- I = 264
