You find the intersection point of the two lines, which is (3, -2).

It is what the question meant when it asked for "solution".

These two lines are y = mx + c, which is another form of linear equations with two variables you are likely familiar with

x+y=20

x-y=10

Hope this clears up your confusion.

why can you NOT divide by zero? explain and write paragraph HELP ASAP PLEASE

Answers

In ordinary arithmetic, the expression has no meaning, as there is no number which, when multiplied by 0, gives a (assuming a ≠ 0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 00 is also undefined; when it is the form of a limit, it is an indeterminate form.

Answer:

you cant divide by nothing. zero has no value so be dividing by nothing. also your outcome would be nothing. hope this helps

Y=6x-72

The left side of the table (x) is increasing by 1 while the right side (y) is increasing by 4. If you add a positive number by a negative number the negative number will start to decrease.
So it started off as
-88+4=-84
Then, -84+4=-80 and so on and so on

Your answer will be Y=6x-72

Step-by-step explanation:

△MNO maps to △RST with the transformation (x, y) longrightarrow ( 1 3 x, 1 3 y). Choose True or False for each statement. A. If RT = 3, MO = 9. A True B False B. If RT = 12, MO = 4. A True B False C. If RT = 9, MO = 27. A True B False

Answers

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the enlargement or reduction in size of a figure. If a figure with point A(x, y) is dilated by a scale factor k, the new point is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

Since ΔMNO maps to ΔRST with a transformation (x, y) = (3x, 3y), this means that ΔRST is three times the size of ΔMNO, hence all the sides of ΔRST are three times that of ΔMNO.

A. If RT = 3, MO = 9. A True B False B.

This is false because RT = 3 * MO = 3(9) = 27

B. If RT = 12, MO = 4. A True B False

This is true because RT = 3 * MO = 3(4) = 12

C. If RT = 9, MO = 27. A True B False

This is false because RT = 3 * MO = 3(27) = 81

A line is 180 so you subtract 126 with 180 and get 54. Since a Triangle angles all equal 180 together you add 54 and 43 and subtract 180 and the answer is 83

Answer:

You have to fine the number that matches with the "X" so the answer would be 126 divided by 43 which is 2.9. 2.9 is closer to 3 than 2 so the "x" is 3
