Answer:

4x - 7y = 19

  • (-4, -5)

4(-4) - 7(-5) = 19

-16 - (-35) = 19

-16 + 35 = 19

19 = 19

(-4,-5) is a solution to given equation.

  • (9, 6)

4(9) - 7(6) = 19

36 - 42 = 19

-6 ≠ 19

(9,6) is not a solution to given equation.

  • (1, -3)

4(1) - 7(-3) = 19

4 - (-21) = 19

4 + 21 = 19

25 ≠ 19

(1, -3) is not a solution to given equation.

  • (-6,2)

4(-6) - 7(2) = 19

-24 - 14 = 19

-38 ≠ 19

(-6,2) is not a solution to given equation.

<u>Note</u>:- <em>A solution to an equation is any value which when substituted to a variable would make the equation true.</em>

Can somebody help with questions 8 plzz‼️

Answer:

53,760,970 households/year

Step-by-step explanation:

First step is to do 65,929,420 - 12,168,450 = 53,760,970

Now divide 53,760,970 by 20 since the difference in 1997 and 1977 is 20

53,760,970/20 = 2,688,048.5

So each year 2,688,048.5 people got cable.

But it would be 53,760,970/year because then you could divide it by how ever many years to see how many people got cable.

Hope this helps!!

How do I find the area of this shape
vazorg [7]
There's two ways, you can either multiply 11 and 7 to get 77 and then divide by 2, OR, you can divide 11 by 2 and get 5.5 and multiply that by 7, hope this makes sense, if you don't understand just comment and I'll explain it more :)

Answer:

x = 7/2

Step-by-step explanation:

The whole triangle is an equilateral triangle--all the sides are the same: 7, 7, 7 and all the angles are equal: 60°, 60°, 60°.

So the line thru the triangle makes two 30°-60°-90° triangles. The shortest side of the right triangle is half the length of the hypotenuse. Also, the line cuts the angle in half (30° and 30°) and also the side: 7/2
