Answer:
[tex]A" =(-1,-1)[/tex] [tex]B" =(-2,1)[/tex]
[tex]C" =(-4,1)[/tex] [tex]D" =(-5,-1)[/tex]
Step-by-step explanation:
Given
[tex]A = (1,1)[/tex] [tex]B =(2,3)[/tex]
[tex]C = (4,3)[/tex] [tex]D = (5,1)[/tex]
Required
The new coordinates after reflected across y-axis and shifted 2 units down
When a point is reflected across the y-axis, the rule is:
[tex](x,y)=>(-x,y)[/tex]
So:
[tex]A = (1,1)[/tex] [tex]=> A' = (-1,1)[/tex]
[tex]B =(2,3)[/tex] [tex]=> B' = (-2,3)[/tex]
[tex]C = (4,3)[/tex] [tex]=> C' = (-4,3)[/tex]
[tex]D = (5,1)[/tex] [tex]=> D' = (-5,1)[/tex]
When a point is translated 2 units down, the rule is:
[tex](x,y) => (x,y-2)[/tex]
So:
[tex]A = (1,1)[/tex] [tex]=> A' = (-1,1)[/tex] [tex]=> A" =(-1,-1)[/tex]
[tex]B =(2,3)[/tex] [tex]=> B' = (-2,3)[/tex] [tex]=> B" =(-2,1)[/tex]
[tex]C = (4,3)[/tex] [tex]=> C' = (-4,3)[/tex][tex]=> C" =(-4,1)[/tex]
[tex]D = (5,1)[/tex] [tex]=> D' = (-5,1)[/tex] [tex]=> D" =(-5,-1)[/tex]
So, the new coordinates are:
[tex]A" =(-1,-1)[/tex] [tex]B" =(-2,1)[/tex]
[tex]C" =(-4,1)[/tex] [tex]D" =(-5,-1)[/tex]

6.) River C is 200 miles longer than River D. If the sum of their lengths is 5,550 miles,
what is the length of each river?
Answer:
River C: 2875, River D: 2675
Step-by-step explanation:
Subtract 200 from 5550. Then divide your difference (5350) by 2 to get 2675. Add 200 to one of your 2675s to get river C's length.

Identify the area of the composite shape.
71 cm squared
98 cm squared
34 cm squared
56 cm squared
Answer:
Option (1)
Step-by-step explanation:
Area of the composite figure ABCDEFGH = Area of rectangle ABGH - Area of rectangle CDEF
Area of rectangle ABGH = Length × Width
= 14 × 7
= 98 cm²
Area of rectangle CDEF = 9 × (7 - 4)
= 27 cm²
Area of the composite figure = 98 - 27
= 71 cm²
Option (1) is the correct option.

The measures of two angles are 4x° and (2x + 12)°. What is the measure of the each angle if x = 13
Answer:
4x° if x=13
4(13)= 52°
2x+12 if x=13
2(13)+13= 38°
Express the function.
f(x) = 2x² - 4x - 13
in the form f(x) = a(x + h)² + k
Answer:
2(x-1)^2-15
Step-by-step explanation:
2x^2-4x=2(x-1)^2-2
insert that in:
f(x)=2(x-1)^2-2-13=2(x-1)^2-15
a=2,h=-1,k=-15

The equation y= 1.56x + 8.36 models the approximate height of a tree in feet after x weeks. Which statements are true about the linear model? Select all that apply.
A. The plant grows a total of 1.56x feet.
B. The initial height of the plant is 1.56 feet.
C. The initial height of the plant is 8.36 feet.
D. The plant grows about 1.56 feet each week.
E. The plant grows about 8.36 feet each week.
Answer and Step-by-step explanation:
C. The initial height of the plant is 8.36 ft.
When you plug 0 in for x, we get the value of 8.36. When x is 0, that means that 0 weeks have gone by, thus the plant starts at a height of 8.36 feet.
D. The plant grows about 1.56 ft. each week.
We see that the number 1.56 is with the x, so for every week that goes by, the growth will be changed by 1.56, thus making the plant grow 1.56 feet each week.

Two
angles, ZJ and ZK are supplementary. The measure of ZJ is (2x+5)°. The
measure of ZK is (3x-10)°. What is the measure of ZK?
Answer:
ZK = 95 degrees
Step-by-step explanation:
Supplementary angles are when the sum of 2 angles equals 180 degrees. Since ZJ and ZK are supplementary, we can add both of them to equal 180 degrees.
ZJ + ZK = 180
Our first objective: find the value of x
(2x + 5) + (3x - 10) = 180
2x + 5 + 3x - 10 = 180
Combine like terms
5x - 5 = 180
Add 5 to both sides to isolate variable x
5x = 175
Divide both sides by 5 to isolate variable x
x = 35
Plug in x value for ZK expression
