Answer:
Problem 13: yes
Problem 14: no
Step-by-step explanation:
Problem 13:
Plug the values of x and y to solve.
-23 = -7(5) + 12
-23 = -35 + 12
-23 = -23
The values are equal, so the coordinates <u>do</u> solve the equation. It's a yes.
-----------------------------------------------------------------------
Problem 14:
Plug the values of x and y to solve.
-9 = -7(-3) + 12
-9 = 21 + 12
-9 = 33
The values are not equal, so the coordinates <u>do not</u> solve the equation. It's a no.
hope this helps :)
Okay first you should subtract 8.50 from 61.60 because the delivery charge doesn't count. 61.60-8.50=53.1. now divide 53.1 by 2.95. 53.1÷2.95=18. Romeo ordered 18 roses for his girlfriend.
Answer:
Its either A or B I believe it's A srry if im wrong.
Simplify both sides of the equation
-5/2 x +3/4 x = -3/4
Combine like terms
(-5/2 x + 3/4 x )
-7/4 x = -3/4
-7/4 x = -3/4
Multiply both sides by 4/(-7)
(4/-7)*(-7/4 x ) = (4/-7 ) * ( -3/4 )
x = 3/7
