If the value a is positive in the linear equation y = a x ( for example: y = 2 x ) then the line ( from the left to the right ) must go up and to the right. It also passes through the origin ( 0, 0 ).           For x = 1: y = 2 * 1 = 2, so that point is ( 1, 2 ),  x2 > x1,  and y2 > y1.Answer:A. goes up and to the right.

Solve the system by substitution<br> 10x=y<br><br> 2x+y=-24
masha68 [24]

Answer: x=-2

Y= -20

Step-by-step explanation

You replace the y in the second equation with 10x. This is because it says 10x=y

2x+10x=12x so you put that

12x=-24

To get x by its self you divide by 12.

-24 divided by 12 is -2.

Now you plug in -2 to either equation as y. I chose the first one because it's easier.

10(-2)=y

-20=y

Juanita ran 8.3 miles in Week 1 and 12.09 miles in Week 2. She used the subtraction below to determine how much farther she ran
AfilCa [17]

Step-by-step explanation:

12.09 - 8.30 = 3.79

The reason why her answer was wrong is because when the '2' gets slashed into a '1' during carry over, it would have been 11 - 8 = 3 instead of a 4. (the 1st column)

The error that Juanita made is that she made a computational error when subtracting.

How much was your loan
leonid [27]

Answer:

Your loan was for $16,000.  

Step-by-step explanation:

The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.

If i = prt, then p = i / (rt)

Here, p = ($1200) / 0.075 = $16,000

Your loan was for $16,000.
