Answer:

You would start your graph at (1,7.5) (2, 15) (3, 22.5) (4, 30) (5, 37.5)  

Step-by-step explanation:

What you do is for every hour you add 7.50. I don' know how many hours you need to graph so I just gave you the first five, But you should start to see a pattern, just continue with the pattern and you will get it right! Hope this helps!

I don’t understand can someone please explain how to work this out and what the answer is
joja [24]

When you see an equation with parenthesis around it, you can use this:

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

Otherwise known as PEMDAS.

We can see that in the equation, there are parenthesis, so we can open those. We open parenthesis by taking the number right next to the parenthesis (or outside the parenthesis) and we multiply that number by everything inside. So this is what it would look like:

-2x^2 - 10x + 8

See how the signs changed? This rule only applies when you multiply something, but here is how I think of it:

+ and + always equals +.

- and - always equals +.

- and + always equals -.

+ and - always equals -.

So that's it! Just to be clear, the answer is:

-2x^2 - 10x + 8

Hope I helped, sorry if I'm wrong!

Explain why receiving a 15% discount is the same as finding 85% percent of the original cost of an item. Then, explain how the m
Lisa [10]

Answer:

15% discount means you're paying 85% of the marked price because total is 100% and 100-15 = 85%

Let X be the naked price

Paid = marked price - discount

Paid = X - (15/100 × X)

Using distribution property,

Paid = X(1 - 15/100)

Paid = X[(100-15)/100]

Paid = X(85/100)

Which is 85/100 × X

Hence 85% of X

Find the equation of a line that is parallel to the line x equals negative 1x=−1 and contains the point left parenthesis negativ
sineoko [7]
The equation of the line is given as y-x=-1

A straight line equation is given in the form y=mx+c where m is the gradient and c is the y-interest.

We need to rearrange y-x=-1 to make y the subject. 
y= x-1 ⇒ from here we can read the gradient and the y-intercept. The gradient, m=1 and c=-1.

<span>A line that is parallel to y=x-1 will have the same gradient, m=1 but different y-intercept. One example of equation of a line that is parallel to y=x-1 is y=x+3
