For any point reflected in the y- axis
(x, y ) → (- x, y )
A(1, 1) → A'(- 1, 1)
B(5, 1 ) → B'(- 5, 1 )
C(3, 3 ) → C'(- 3, 3 )
Answer:
Step-by-step explanation:
15/3= 5
Orrrr
15/-3=-5
answer:
it is not proportional.
step-by-step explanation:
14-10.50=3.5
17.50-14=3.5
24.50-17.50=7
in order for it to be proportional, they would all have to equal the same number and since in this case, they don't it is non-proportional
hopefully, this helps :)
have a nice day !!
i'm extremely sorry i couldn't help sooner :(
Answer
He should've drawn the arrow starting from -15 pointing right to show how adding these two numbers would equal zero... hope this helped
Step-by-step explanation:
Answer:
x = -5 and y = 8
Step-by-step explanation:
To solve the system by substitution, solve one equation for a variable. Then substitute the equation into the other equation.
x + 2y = 11 becomes x = 11 - 2y
Substitute x = 11 -2y into 4x + 4y = 12.
4(11-2y) + 4y = 12
44 - 8y + 4y = 12
44 - 4y = 12
32 = 4y
y = 8
Substitute again with y = 8 into the equation to find x.
x = 11 - 2(8)
x = 11 - 16
x = -5
