Answer:
(B)
The areas of the square and parallelogram are equal
Point S (6,-4)
Point T
(6 x -1, -4) = (-6, -4)
Point T = (-6,-4)
Point T shows the reflection of Point S across the y axis.
Hope this helps :)

Answer:
<h2>B. 4</h2>
Step-by-step explanation:
Since ,AB is the mid segment of triangle LMN
Then
Answer:
1.57 gallons of water to the nearest hundredth.
Step-by-step explanation:
The number of minutes in a day = 24*60 minutes.
1 L = 0.26 gal
So 4.2 milliliters = 0.26 * 4.2 / 1000 gals.
So the number of gallons leaked in a day
= 24* 60 * (0.26*4.2) / 1000
= 1.572 gals.
There are two ways to do this
Method 1:
Find (f-g)(x) first
(f-g)(x) = f(x) - g(x)
(f-g)(x) = (5x^2+3) - (-2x+4)
(f-g)(x) = 5x^2+3+2x-4
(f-g)(x) = 5x^2+2x-1
Then plug in x = -3
(f-g)(-3) = 5(-3)^2+2(-3)-1
(f-g)(-3) = 5(9)+2(-3)-1
(f-g)(-3) = 45-6-1
(f-g)(-3) = 39-1
(f-g)(-3) = 38
-----------------------------------------
Method 2:
Find f(-3)
f(x) = 5x^2+3
f(-3) = 5(-3)^2+3
f(-3) = 5(9)+3
f(-3) = 45+3
f(-3) = 48
Find g(-3)
g(x) = -2x+4
g(-3) = -2(-3)+4
g(-3) = 6+4
g(-3) = 10
Subtract the two results
(f-g)(-3) = f(-3) - g(-3)
(f-g)(-3) = 48 - 10
(f-g)(-3) = 38
-----------------------------------------
Whichever method you pick, the answer is: 38
