Solve the system of linear equations.<br> 15x - 5y = -20<br> -3x + y = 4
disa [49]

Answer:

Infinite solutions.

Step-by-step explanation:

Use the elimination method:

15x - 5y = -20

-3x + y = 4              Multiply this equation by 5:

-15x + 5y = 20         Now add this to the first equation:

0 = 0

So the 2 equations are the same and there are infinite solutions.

Ricky rides his bike 12 miles every day he stops 7 miles to rest write and solve an equation to find out how much further he has
kondor19780726 [428]
<h3><u>Question:</u></h3>

Ricky rides his bike 12 miles every day. He stops after 7 miles to rest. write and solve an equation to find out how much further he has to ride

<h3><u>Answer:</u></h3>

Ricky has to further ride for 5 miles

<h3><u>Solution:</u></h3>

Given that, Ricky rides his bike 12 miles every day

Let "x" be the remaining distance in miles he has to ride further

Total distance = 12 miles

Also, given that he stops after 7 miles to rest

Therefore, already covered distance = 7 miles

Therefore, we can frame a equation as,

remaining distance + already covered distance = total distance

x + 7 = 12

Solve the above equation for "x"

x = 12 - 7

x = 5

Thus Ricky has to further ride for 5 miles

The excel output is attached here.

Therefore, the equation of the linear regression is:

\hat{y}=21.9028+1.5736x

Where:

21.9028 is the intercept and 1.5736 is the slope.
