Answer:
Step-by-step explanation:
two points on the line are (-2,0) and (0,4)
slope=(y2-y1)/(x2-x1)=(4-0)/(0-(-2))=4/2=2
eq. of line is y-0=2(x-(-2))
y=2(x+2)
y=2x+4
Answer:
Each algebra book costs $60.
Step-by-step explanation:
A=bill for algebra books; S=bill for science books=A+$360
S+A=$3960 Substitute for S
A+$360+A=$3960 Subtract $360 from each side.
2A=$3600 Divide each side by 2.
A=$1800 The order for 30 algebra books cost $1800.
Individual book=A/30
individual book=$1800/30=$60 ANSWER: Each algebra book cost $60.
