The side length is 12 - -3 = 15 so the area is 15 squared = 225.
That's an equation that describes a linear and proportional relationship between 'x' and 'y'. The graph of that equation is a straight line through the origin whose slope is. 1/3 .
Answer:
x = 1
Step-by-step explanation:
Rearrange equation by making x's on one side and numbers on the other
2x - x = 9 - 8
x = 1
The answer is G. I know because, 1.75 * 3 (slices of pizza) = 5.25.
13.75 - 5.25 = 8.5
8.5 / 4 (hot dogs) = 2.1 (price per hot dog)
We can apply this to Sarah by saying
2 * 1.75 = 3.5
3 * 2.1 = 6.3
Added equals 9.8 or 9.75 (Sarah's total)
Correct me if I am wrong hope this helps:)
Y^2+4y=-8
add 8 both sides
y^2+4y+8=0 in the form of ax²+bx+c=0
Factor it
by formula
-b+-(√b²-4ac)/2a
-4+-(√16-32)/2*1
-4+-(√-16)/2
-4+-4i/2
-2+-2i where√-1=i
