Answer:

y = 20x + 40

Step-by-step explanation:

Given that the rental rate for a cement mixer has a flat rate of $40 plus $20 for each day of the rental.

That means fixed one time cost is $40 which doesn't changes with time.

If number of days is represented by "x" then rental cost for "x" days will be 20 times x or just 20x.

So the final cost will be sum of fixed cost and the rental cost per day which is:

20x+40

Now if "y" represents total rental cost over time then final cost equation can be written as:

y = 20x + 40

Hence final answer is y = 20x + 40y = 20x + 40.

Talja [164]

Answer:

x = -3

y = -8

Step-by-step explanation:

2y = x - 13

3x = y - 1;  let y = 3x + 1

substitute to solve for 'x':

2(3x + 1) = x - 13

6x + 2 = x - 13

5x + 2 = -13

5x = -15

x = -3

solve for 'y':

3(-3) = y - 1

-9 = y - 1

-8 = y

Answer is D the last one

if the equation is y= 3 lx + 2l

if you solve for x then the zero is x= -2

if y intercept .. so x = 0 

then point is (0,6)

hope that helps
