Answer:

x = infinite amount of solutions

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Algebra I

Solving systems of equations using substitution/elimination
Solving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

y = 2/3x + 4

2x - 3y = -12

Step 2: Solve for x

Substitution

Substitute in y: 2x - 3(2/3x + 4) = -12
Distribute -3: 2x - 2x - 12 = -12
Combine like terms: -12 = -12

Here we see that -12 does indeed equal -12.

Therefore, our x would equal infinite amount of solutions.

Step 3: Graph systems

Check the systems.

We see that the 2 lines are the same.

Answer:

If it is being dilated from (0,0) the answer is below.

Step-by-step explanation:

It depends on where it is scaled from. If you choose a point directly to that points left it will be pushed tot he right, and vice versa if it is on its right. Same for above and below

I am going to assume we are dilating from (0,0), but again, if there is another part of the question saying where it's from use this method for that as well.

So, from (0,0) the initial point is (-3, 11) Scaling by a factor of 3 means it gets pushes AWAY so it is 3 times as far away. (If it were a fraction or decimal it would be getting pulled closer)

Using (0,0) as the dilation point is the easiest because we just have to ask how far are the x and y coordinates away from (0,0) and any number is THAT number away from 0.

We break this into the two coordinates too. so how far is -3 from 0? -3. so we want a point 3 times as far away, so what is that? -9. Same for 11, 11 is 11 away from 0 so we want it 3 times as far, which is 33.

Now that we have the two coordinates that is the answer.

(-9, 33)

A student skipped a step when she tried to convert 15 hours to seconds, and she got the following incorrect result:

givi [52]

1hr/3600sec=15hr/x

(3600sec)(15hr)=(1hr)x

x=54000seconds

15 hours is 54000 seconds
