Answer:
y = 100 - 2.5 x is the equation that represents her total profit from
the project
Step-by-step explanation:
The given is:
1. An electrician earns 100 dollars for a project installing light fixtures
2. She must pay for the light fixtures herself and they cost 2 dollars
and 50 cents each
3. x represent the number of light fixtures and y represent her
total profit
Her profit is the amount of money she has left over after paying for
the light fixtures
∵ The cost of each light fixtures is 2 dollars and 50 cents
- Let us change the cents to dollar
∵ $1 = 100 cents
∴ 50 cents = dollar
∴ 2 dollars and 50 cents = $2.5
∵ Her profit = The money she earns - The money she pays
∴ The cost of each light fixtures = $2.5
∵ She installs x light fixtures
∴ She pays 2.5 x dollar
∵ She earns $ 100 for installing x light fixtures
∵ Her profit is $y
∴ y = 100 - 2.5 x
y = 100 - 2.5 x is the equation that represents her total profit from
the project

Answer:
(20x30)= 600
that's the area of rectangular plot
3ft wide sidewalk means both +3 on left and +3 on right, also both +3 up and +3 down
which means u have to do 26x36=936
then subtract
936-600=336 square feet

Answer:
1. 15 grapes eaten per minute.
Step-by-step explanation:
We have been given a table that shows the number of grapes eaten over several minutes. We are asked to find the rate of change of our given function.
Since we know that rate of change of a function can be found by vertical change of the function divided by horizontal change of the function.
=Difference between two y-coordinates.
=Difference between corresponding x-coordinates of y-coordinates.
Upon substituting coordinates of any two points in above formula we will get,
We can see that rate of change of our given function is 15 grapes eaten per minute and 1st option is the correct choice.
Step-by-step explanation:
Yes, the statement is true "A state becomes good if its people are good". Government is one of the most important body for the good future of any country. The difference between a good and bad country occurs due to its government and governance. Similarly, citizens plays a vital role for the difference between good and bad state.
