What is the solution to this linear system?

1 answer:

5 0

The answer is (-1,7)

I got this answer because to solve a system, you find the point on the graph where both lines intersect. And that point in this graph is (-1,7). Hope this helps!:)))))

Answer:

$Q'=(4,1)\\R'=(6,-5)\\S'=(3,-4)\\T'=(1,-1)$

Step-by-step explanation:

First we have to find the coordinates of the original ordered pairs then we will do the translation.

$Q=(1,3)\\R=(3,-3)\\S=(0,-2)\\T=(-2,1)$

Now we will add 3 to every x value and add a -2 to every y value.

$Q=(1_{+3},3_{+(-2)})\\R=(3_{+3},-3_{+(-2)})\\S=(0_{+3},-2_{+(-2)})\\T=(-2_{+3},1_{+(-2)})$

When you do that you will get the new prime points.

$Q'=(4,1)\\R'=(6,-5)\\S'=(3,-4)\\T'=(1,-1)$

Need help on all these questions!!

Okay, so YZ = 3 cm. You have XM correct. And YM = 0.5.

Now, you have the midpoint M at the correct spot.

Use Pythagorean's theorem o find the length of AB. a² + b² = c² a=6, b=8.

6² = 36 8² = 64 36 + 64 = 100 AB = 10!

If AB = 10 then AM = 5 MB also = 5

If B is the midpoint of AC, C would be 12 rows down from A, and 16 columns to the right. The last spot where the line intersects.

There are your answers!
