What point would be reflected across the y-axis to ( − 3, − 9) ?

Mathematics

Aloiza [94]3 years ago

Answer:

(-3, 9)

Step-by-step explanation:

If a point was reflected across the y-axis, then the y-coordinate would change signs (from negative to positive or from positive to negative). Using this, we could find the original point by changing the sign of the y-coordinate. As you may already see, this is really just reflecting the point across the y-axis again. By doing this, you get the point (-3, 9).

The point would be (-3, 9).

I hope this helps. :)

MArishka [77]
The perimeter of an object is found by adding all of the sides.  The sides of his frame would be 2 ft, 2 ft, 1.5 ft (18 inches / 12 inches per foot = 1.5 feet), 1.5 feet.  Adding these together we get a total length of 7 feet.  However, he may want to use a slightly longer board to account for any errors!

4(2x - 5) <=== this one is correct...not 100% sure who wrote it

8x - 20...factor out a 2

2(4x - 10) <==== this is correct

8x - 20....factor out a -2

-2(-4x + 10) <==== this is correct

8x - 20....factor out a -4

-4(-2x + 5).....nobody did this one......but somebody tried....that person didn't factor correctly

Evaluate the expression 2x + x, when x = -3.<br> O<br> A<br> -12<br> O B-9<br> OC -3<br> ooo
svp [43]

Answer:

Option B) -9 is correct

The evaluated given expression when x=-3 is 2x+x=-9

Step-by-step explanation:

Given expression is 2x+x

Now to evalute the given expression when x=-3 as below :

2x+x when x=-3

That is put x=-3 in the given expression we get

2x+x=2(-3)+(-3)

=-6-3

=-9 ( adding the like terms here )

Therefore 2x+x=-9

The evaluated given expression when x=-3 is 2x+x=-9

Option B) -9 is correct

Mr. Schnee is refinancing his home. His loan officer has presented him with the following two offers; it is worth noting that Mr
erastovalidia [21]

The option that best suits him is 4.0% Interest Rate for 30 years with a monthly payment of $ 1,193.54 with $ 10,362 in Closing Costs.

Given that Mr. Schnee is refinancing his home, and his loan officer has presented him with two offers, to determine which offer should he take in order to maximize his benefit, the following calculation must be performed:

A) 4.5% Interest Rate for 30 years with a monthly payment of $ 1,266.71 with $ 256 Closing Costs

1,266.71 x 30 x 12 + 256 = X

1,266.71 x 360 + 256 = X

456,015.60 + 256 = X

456,271.60 = X

B)4.0% Interest Rate for 30 years with a monthly payment of $ 1,193.54 with $ 10,362 in Closing Costs

1,193.54 x 30 x 12 + 10,362 = X

1,193.54 x 360 + 10,362 = X

429,674.40 + 10,362 = X

440,036.40 = X

Therefore, the option that best suits him is 4.0% Interest Rate for 30 years with a monthly payment of $ 1,193.54 with $ 10,362 in Closing Costs.
