Answer:
1. y+5=4x-40
2.y=4x-45
Step-by-step explanation:
To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4
Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45
Answer:
The answer is 9x-4.
Step-by-step explanation:
First calculate the area of the backyard. This is 13x-1. Then multiply the area of the patio so multiply x +3 by x+ 3. The answer to this is 4x+3. Next subtract the area of the patio from the area of the backyard. The answer is 9x-4.
Answer:
I think it is a but it is hard to see
Step-by-step explanation:
Using variable concepts, of dependent and independent variables, it is found that the dependent variable is the amount of sales dollars earned.
<h3>What is the relation between a function and the dependent and independent variables?</h3>
- A function has the following format: y = f(x).
- In which each value of y is a function of one value of x, and thus, <u>x is the independent variable and y is the dependent variable</u>.
- That is, the input of the function is the independent variable and the output is the dependent variable.
In this problem, the manager believes that the amount of sales dollars earned is a function of the number of contacts that the salesperson makes, hence:
- The number of contacts is the independent variable.
- The amount of sales dollars earned is the dependent variable.
