A truck can be rented from company A for $100 a day plus $0.20 per mile. Company b charges $80 a day plus $0.30 per mile to rent
Fittoniya [83]

Answer:

2000

Step-by-step explanation:

A(m) = 100 + 0.20m

B(m) = 80 + 0.3m

For company A to have a better deal, the truck must be driven more than __ miles per day.

Solve::

100 + 0.2m < 80 + 0.3m

-------

20 < 0.1m

m > 2000/1 = 2000 miles

---------------

2500 mi

Which equation shows a y- intercept of -5
Assoli18 [71]

Hi there!  

»»————- ★ ————-««

I believe your answer is:

Option B) y=x-5

»»————- ★ ————-««  

Here’s why:  

  • Most options (Second, Third, and Fourth) are in slope intercept form.

⸻⸻⸻⸻

\boxed{\text{Slope-Intercept Form}}\\\\y=mx + b\\\\\boxed{\text{Key:}}\\\\m - \text{The Slope}\\\\b- \text{The Y-Intercept}

⸻⸻⸻⸻

  • We are looking for the equation where '-5' is in b's place.

⸻⸻⸻⸻

\boxed{\text{Which equation shows a y-intercept of -5?}}\\\\---------\\\text{A}) -5y = x\\\\\text{This equation in slope-intercept form is  }y=\frac{1}{5}x.\\\\\text{The 'b' part is not shown. This means that the line passes through the}\\\text{origin.}\\\\---------\\\\\text{B})\text{ }y = x-5\\\\\text{This option shows a slope of one and a y-intercept of -5.} \\\\\text{Therefore, \boxed{\text{option B is the correct answer.}}}\\\\----------\\\text{Option C has a y-intercept of 5, and Option D has a}\\

\text{y-intercept of 1.}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
