Answer:
Y= 3.2b + 100
Step-by-step explanation:
That is the equation needed to find the value of b. since Omar bought the cup at the fixed price of 100 we know that no matter what the answer has to be over 100. So that becomes our Y intercept. 3.2 percent is how much the price inflates every year.

Answer:
40 cm
Step-by-step explanation:
Step one:
Given data
Diagonal = 50cm
If the length on one of the sides is 30cm
Then applying Pythagoras theorem we can find the other side as
Step two:
![d^2= l^2+w^2\\\\50^2= 30^2+w^2\\\\2500=900+w^2\\\\2500-900= w^2\\\\1600=w^2\\\\](https://tex.z-dn.net/?f=d%5E2%3D%20l%5E2%2Bw%5E2%5C%5C%5C%5C50%5E2%3D%2030%5E2%2Bw%5E2%5C%5C%5C%5C2500%3D900%2Bw%5E2%5C%5C%5C%5C2500-900%3D%20w%5E2%5C%5C%5C%5C1600%3Dw%5E2%5C%5C%5C%5C)
square both sides we have
w= √1600
w= 40 cm
Ok so easy peasy
remember that when divide or multiply by negative, reverse the inequality symbol example
2>3 times -1=
-2<-3 so
-150x<u>></u>-2400
divide both sides by -150
flip sign
<u />x<u><</u>16
-336<u>></u>-21y
divide both sides by -21
flip sign
16<u><</u>y
they seem to have the same solution
x=y<u>></u>16
The answer is 82 and your welcome
