Answer:

Yes, all three of them are proportional

Step-by-step explanation:

First, let's simplify them all the way:

10/45 = 2/9

20/90 = 2/9

6/27 = 2/9

All three of these ratios simplified down to their simplest form are 2/9, meaning that they are all proportional.

Can someone find the points/coordinates of this graph?
BigorU [14]

Answer:

The x represents the value of the point on the x axis or the horizontal line, and the y represents the vertical line. Now, lets solve for the first point. We can first see that it only moves to the left by two from zero, which is basically -2. So, right now we have (-2,y). We then look for the y in which we see that it is down -6 from zero, so it will be (-2,-6). Time to look for the second point. We should get (2,-3). Now, with these two points, it is time to find the slope intercept form.

The system of equations can be solved using linear combination to eliminate one of the variables. 2x − y = −4→10x − 5y = −20 3x
tester [92]

Answer:

Option D is correct.

13x = 39

Step-by-step explanation:

The system of equation is given:

2x-y = -4             ....[1]

3x+5y = 59         .....[2]

Multiply equation [1] by 5 to both sides we have;

10x-5y = -20              .....[3]

Using elimination method:

Add [2] and [3] equations to eliminate y and solve for x, we have;

13x = 39

Divide both sides by 13 we get;

x = 3

Substitute x in [1] we have;

2(3)-y = -4

6-y = -4

Subtract 6 from both sides we have;

-y = -10

Divide both sides by -1 we have;

y = 10

⇒Solution: (3, 10)

Therefore, an equation can replace 3x+5y = 59 in the original system and still produce the same solution is,

13x = 39
