Hello there!

The answer is 13 trust me. the answer should be 29 for no reason. but answer 13 and you'll get it right.

I don't know how to take a screen shot and post. but the easy way is to count . so 50 years old = 15. 60 years old = 8. 70 years old = 4. 80 years old = 2. add them.

Answer:

1.  Consistent independent.

2.  Coincident

3.  Inconsistent.

Step-by-step explanation:

4x + y = 8

x +  3y = 8   Multiply this equation by -4:

-4x - 12y = -32

Adding this to the first equation:

-11y = -24 giving y = -24/-11 = 2.18

Substituting in the first second equation:

x + 3(2.18) = 8 giving x = 1.46.

So this system of equations has roots (1.46, 2.18)  and is consistent independent.

2.

-4x + 6y = -2

2x - 3y = 1   Multiply this by -2:

-4x + 6y = -2

So these 2 equations are the same and will give the same graph on the coordinate plane, and so has:

Infinite solutions  and is coincident.

3.

5x - 2y = 4

5x - 2y = 6

We can see immediately that this system of equations has NO Solutions.

If we subtract the 2 equations  we get:

0 = -2 which is of course, absurd.

Classification Inconsistent.

Four times the difference of a number and 7 is 32
notka56 [123]
I'm not exactly sure but I think it might be but if you were to do 4(x-7) that would be 15 because fifteen minutes seven equals eight and eight time four is thirty two Hope this helps!

Complete the equation of the line through [1,4] and [2,2]
son4ous [18]

First find the slope of the line so change in y over change in x so 4-2/1-2 which is 2/-1 so -2 is your slope then plug that as well as a point from above to find your y intercept so y=mx+b 2=-2(2)+ b then you have 2=-4+b then add 4 to each side and you find b is six then you make ur equation from your slope and y int(b) y=-2x+6
