Answer:
D. 45 degree counterclockwise rotation
Step-by-step explanation: :
The original image is triangle TUV and it has been rotated counter clockwise to form triangle T'U'V' using the origin as the center of rotation. . The rotation is 45 degrees rotation.
Hence, option B is correct.

The goal is to raise AT LEAST $180, so this automatically indicates that the amount of keychains sold with the price must be the same or more than $180.
k = number of keychains
each keychain is $2.25
2.25k ≥ 180
divide both sides by 2.25 to get the k alone
k ≥ 80
The answer is 2.25k ≥ 180, k ≥ 80
(Hope this isn't confusing)
Answer: 8.1
Step-by-step explanation:
758.16 ÷ 13 =58.32
58.32 ÷ 7.2 = 8.1
Check: 8.1 ×13 ×7.2=758.16
Find three solutions of the equation y=7x-5. (A)(3,-26),(-1,-12),(3,16) (B)(-3,-26),(-12,-1),(16,3) (C)(-3,-26),(3,16),(1,-12) (

Answer:
(D)(-3,-26),(-1,-12),(3,16)
Step-by-step explanation:
Given : y=7x-5.
To find : Find three solutions of the equation .
Solution : We have given that y=7x-5.
We need to choose the values from the given option
Let x = -3
y = 7(-3) -5
y = -21-5
y = -26
(-3,-26)
For second solution
Plug x = 3
y = 7( 3) -5
y = 21 -5
y = 16
Then ( 3, 16)
Now , plug x = -1
y = 7(-1) -5
y = -7-5
y = -12
( -1,-12)
Therefore, (D)(-3,-26),(-1,-12),(3,16)
i think that A pair of an input value and its corresponding output value is called an ordered pair and can be written as (a, b). In an ordered pair the first number, the input a, corresponds to the horizontal axis and the second number, the output b, corresponds to the vertical axis.
We can thus write our values as ordered pairs
(0, 0) - This ordered pair is also referred to as the origin
(1, 2.5)
(2, 5)
(3, 7.5)
These ordered pairs can then be plotted into a graph.
