Rewrite in standard form (only)<br>5x+10y=30<br>8x +2y=12<br>-12x+3y=27<br>-24x-12y=60<br>​
tino4ka555 [31]

Answer:

Below in bold.

Step-by-step explanation:

Standard form is Ax + By = C

where A, B and C are integers  and A must be positive.

So the first 2 are already in standard form but the last 2 can be converted to standard form by multiplying each term by -1:

-12x+3y=27

= -1*-12x + -1*3y = -1*27

12x - 3y = -27   is the answer.

The last one is:

24x + 12y = -60.

How to get the right answer
marusya05 [52]

Answer:

15 cm

Step-by-step explanation:

Write out the formula:                                     a^2 + b^2 = c^2

Plug in the numbers that you were given:    a^2 + 6^2 = 16^2

Solve for the numbers that you were given: a^2 + 36 = 256

Subtract:                                                                  - 36 = - 36

                                                                          a^2         = 220

Then, you find your answer:                            a^2 = 220

The square root of 220 is 14.832396974191326. But you are going to round it and you get 15. So, the answer is 15 cm.

Hope this helps

Answer:

true

Step-by-step explanation:

Considering we have a line segment for (0,0) to (0,8).

The midpoint is (0,4).

The formule for calculate the distance between two points is:

\sqrt{(x2-x1)^{2}+ (y2-y1)^{2}}

We substituye the values:

\sqrt{(0-0)^{2} + (8-0)^{2} } = 8

The point halfway between the endpoints is (0,4)

that is the half of the distance between the points.
