Answer:
7.2% increase (rounded up to the nearest tenth of a percent)
Step-by-step explanation:
The price of the notebook today is $3.70
The price of the same notebook (original price) yesterday was $3.45
Increase in price = $3.70 - $3.45 = $0.25
Percentage increase = (Increase ÷ original price) × 100
Percentage increase = × 100 = 7.2% (rounded up to the nearest tenth of a percent)
Answer:
(x, y) = (6, 1) is the solution
Step-by-step explanation:
Each of the equations is written in "slope-intercept" form:
y = mx + b . . . . . . . . where m is the slope and b is the y-intercept
<u>First equation</u>
The y-intercept is +7 and the slope is -1. That means the line goes down 1 unit for each unit it goes to the right. It will go through the points (0, 7) and (7, 0).
<u>Second equation</u>
The y-intercept is -2 and the slope is 1/2. That means the line goes up 1 unit for each 2 units it goes to the right. It will go through the points (0, -2) and (4, 0).
The lines will intersect at the point (6, 1), which is the solution found by graphing.
