Answer:

AB is located at A(-2,0) and B(2,0) and is twice the length of A'B''

Step-by-step explanation:

the AB is dilated 1/2 so it will be twice the length of A'B'

Two equations are given below:

goldenfox [79]

Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.

Let's substitute b-2 into the first equation wherever there is an a.

a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3

Now let's find a by substituting -3 into either of the equations to find the value of a.

a = b - 2
a = -3 - 2
a = -5

So your solution set is (-5, -3)

Quick question if I had a problem that was sin x = 18.9/20 =.945 how would I inverse sin of both sides ?

galben [10]

Answer:

The result is about 70.9 degrees

Step-by-step explanation:

Easy for a calculator. If you're not using a calculator, it's much more tedious!

There is an inverse sine key on your calculator, but you may have to press a key (likely labeled 2nd or INV) first. The attached image shows a TI-83 display. To get the inverse sine, I first pressed the yellow 2nd key, then the sin key.

Check MODE first to make sure you're measuring angles in degrees (if that's what you want!). Some calculators display angle mode with a small letter at the top of the display, D, R, or G usually.

The left side of the equation produces just x.

$\sin{x}=.945\\\\\sin^{-1}(\sin{x})=\sin^{-1}(.945)\\x=\sin^{-1}(.945) \approx 70.9^\circ$
