Answer:

One solution

Step-by-step explanation:

By inspection, you can see that adding either 3x or 4x to y yields the same result of 7, meaning that x must be 0. If x is 0, y must be 7, meaning that this equation has only one solution. Hope this helps!

Mabel is comparing the prices of two car rental companies. Company A charges $35 per day and an additional $15 as service charge

patriot [66]

Company A : C = 35D + 15....C is total cost and D is number of days
company B : C = 42D + 10...C is total cost and D is number of days
================
which company charges less for renting for 6 days
company A :
C = 35(6) + 15 = 225

company B :
C = 42(6) + 10 = 262

so company A charges less when renting for 6 days
=================
for 10 days...
company A :
C = 35(10) + 15 = 365

company B :
C = 42(10) + 10 = 430

so there would be (430 - 365) = 65 saved when using company A instead of company B

Decide whether the table represents a linear or exponential function circle with a linear exponential then write the function fo

Sergio [31]

This function starts at $(0,3)$ , so we have $f(0)=3$ .

Then, every time $x$ increments by 1, $y$ doubles. This is typical of exponential functions. In linear functions, every time $x$ increments by 1, $y$ increments by a fixed amount (the slope of the function).
