Answer:
See below & see pic.
Step-by-step explanation:
To reflect over the line y = x, switch the x- and y-coordinates of each point.
P(-9, 2) becomes P'(2, -9)
Q(-9, 8) becomes Q'(8, -9)
R(-10, -1) becomes R'(-1, -10)
6r + 10
Explanation:
2(5 + 3r)
= (2)(5 + 3r)
= (2)(5) + (2)(3r)
= 10 + 6r
= 6r + 10
The Y-intercept is showing how many candy bars were sold in 2000 since x is every year after 2000 (hope that makes sense)
I think the answer for the 3) is S=(a×ha)÷2= (7×4.2)÷2= 29,4 ÷2=14.7
And for the 5) one im really not sure.
This is an identity or infinite solutions
10x - 12y = 22
5x - 6y = 11
-2(5x - 6y = 11 )
-10x + 12y = -22
0=0
Identity solution
