Answer:
y = 100 - 5x
Step-by-step explanation:
Total amount of gift card = $100
Amount spent per day = $5
Number of days = x days
Write an equation to show the amount left on the card after x days
y = 100 - 5x
Where,
y = amount left on the gift card
x = number of days
For example,
Assume x = 2 days
Amount left on the gift card, y
y = 100 - 5x
y = 100 - 5(2)
= 100 - 10
= 90
y =$90
Answer:
the pythgorean theorem is
a^2 +b^2=c^2
Step-by-step explanation:
Answer: Part (a) 218.4 Part (b) 54.6
Step-by-step explanation: Part (a) you multiply all the numbers together, then you get 218.4, there is no need to round to the nearest tenth because the decimal is in tenths. (All you got to do is single digit multiplication and two digit multiplication :) Part (b) multiply 5.2 and 10.5, you get 54.6
You're welcome, hope this helps :)
The slope of the line that passes through the points, (3, 4) and (-4, -5) is: A. 9/7.
<h3>How to Determine the Slope of a Line?</h3>
The slope of a line can be calculated by using the slope formula, which is given as:
Slope (m) = change in y / change in x or rise / run.
Given that the following points lie on a line:
The slope of the line would be solved using the slope formula as explained below:
Slope (m) = change in y / change in x = (-5 - 4) / (-4 - 3)
m = -9 / -7
Slope (m) = 9/7.
Therefore, the slope is identified as:
a. 9/7.
