The equation of the blue graph is B because the vertex is (-4,-2), so the -4 is represented as (x+4) because when that is set to 0, x=-4; -2 stays as -2. I don’t think this is a very clear explanation so sorry if this doesn’t help!
Since she already had an integer you do (-9)-10=-19 Then you would do (-19)-8=-27 Then you do -27 + 14=-13 Then -13 + 12=-1 or you can just do -27 + 14 + 12=-1. That's the answer
Company A: y=6x+12
Company B: y=5x+15
x is the variable for how many windows they clean.
A:
y=6(8)+12
y=48+12
y=60
B:
y=5(8)+15
y=40+15
y=55
Company B charges less for 8 windows.
A:
y=6(6)+12
y=36+12
y=48
B:
y=5(6)+15
y=30+15
y=45
Company B charges $3 less than Company a to clean 6 windows.
Answer:
1/5
Step-by-step explanation:
divide each side by 5
5x/5=1/5
simplify
x/5=1/5
