Y=-1/2+2
The y intercept is clearly 2 and you're going down 2 over two every time so your slope is -1/2.
1) first you multiply each side by -2
1a) that clears the -1/2
x = -12
Answer:
E. 120
Step-by-step explanation:
Let's say the number of total flowers is (15+2)x
That means the number of geraniums is 2x.
That also means that 1020 = 17x, which makes x = 60
Because 2x = geraniums and x = 60, the number of geraniums is 120
First step
5.(2x-8)
= (5.2x) + (5. (-8) )
=10x + (-45)
note :(+) . (-) = (-)
so + (-45)= (-45)
Add 15 to this equation
= 10x -40 +15= -15
=10x -25= -15
Leave x alone and make it positive
By the way, if you put (-25) in the right term, this number's notation (I mean -) will change
Namely
= 10x= (-15)+25
=10x= 10
x=1
Hope it helps :)
P.s. I dont know mathematical terms that's why i couldn't explain it properly but i tried to help as far as i can :)
Changes in a coordinate

can be observed with 90 degree rotations about the origin.
90 degrees CW =

180 degrees CW =

270 degrees CW =

Let's observe M(10, 12) and M'(12, -10).
Since they switched and the x value became negative, it must have been a
90 degree rotation.
