Answer:
A' (- 1, - 5 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ), then
A (- 5, 1 ) → A' (- 1, - 5 )
Answer:
-0.83 <√4 <2.63 <√8
Step-by-step explanation:
We need to place the numbers √4, 2.63, √8, and-.83 in order from least to greatest.
We know that,
√4 = 2, √8 = 2.82
A number line starts from negative no then 0 and finally positive numbers.
The smallest no is negative no i.e. -0.83 and the greatest no is √8 i.e. 2.82
The sequence from least to greatest is :
-0.83 <√4 <2.63 <√8
Answer:
x = 3y + 1
Step-by-step explanation:
You need to find the relationship between x and y before finding the y-intercept.
0-(-1) = 1
1-0 = 1
2-1 = 1
1-(-2) = 3
4-1 = 3
7-4 = 3
As x increases by 1, y increases by 3.
At x = 0, y is already 1. Thus:
x = 3y + 1
Unit rate is the thing that describes y and x
The amount that Mark spent = ' M ' .
Katie spent (M + 1).
The equation is: M + (M + 1) = 5
