Answer:
Graph (1)
Step-by-step explanation:
Given rule for the rotation of a figure is,
A(x, y) → A'(-y, x)
This rule defines the rotation of point A by 90° counterclockwise about the origin.
Coordinates of point A → (-2, 0)
Coordinates of point C → (-1, 0)
Following the rule of rotation,
A(x, y) → A'(-y, x)
A(-2, 0) → A'(0, -2)
C(-1, 4) → C'(-4, -1)
Now search the image points from the graphs attached,
Graph (1) will be the answer.
Answer:
A
Step-by-step explanation:
(f+g)(x) means to do f(x)+g(x). We will add both functions together.
Answer a
Answer:
Step-by-step explanation:
Flora picks a cherry then replaces it then picks another cherry, there are 8 cherries so if you take away one you still have 7 and 7 > 6.
Answer: y= 4 or y= -12
Step-by-step explanation:
Y²-8y+16=64.
Rearrange
Y²-8y+16-64=0
Y²-8y-48=0
(Y²+12y)-(4y-48)=0
Y(y+12)-4(y+12)=0
(Y-4)=0 or (y+12)=0
Y-4=0 or y+12=0
Y=4 or y=-12
Answer: 7x + 2y + 2
Step-by-step explanation:
4(3x) + 7 - 5x - 5 + 3y - y
= 12x + 7 - 5x - 5 + 3y - y
= 7x + 2y + 2
