Answer is A and B. Solutions are where the two graphs cross, so you just need to find those coordinates, which are (-5,-13) and (2,-6).
Answer:
x=165
Step-by-step explanation:
Multiply both sides by 15
15(x/15)=11*15
x=165
It splits into 6 easerly so just make each part double walls as the pic shows
Remember to include the positive and negative roots
(7x-2)^2=256
sqrt both sides
7x-2=+/-16
add 2 to both sides
7x=2+/-16
divdide both sides by 7
x=(2+/-16)/7)
x=(2+16)/7=18/7=2 and 4/7
x=(2-16)/7=-14/7=-2
x=2 and 4/7 or -2
well from my understanding of the problem and calculations i would say.. (-5.5,0)
