Answer:
B is the Y-Intercept of the graph/equation
Step-by-step explanation:
Answer:
x = 323 in
Step-by-step explanation:
Given triangles are similar, so their corresponding sides would be in proportion:
3ft = 3*12 = 36 in
5ft 8 in = 5*12 + 8 = 68 in
14 ft 3 in = 14*12 + 3 = 171 in

So there are two ways.
First you could solve for y and plug it into the calculator. one equation for y1 and another for y2. Then go 2nd trace and press 5 and then press enter 3 times to find the intersection.
the second way is to solve by hand. I would suggest solve the first equation for y and plug the equation solved for y into the other equation. so y = -3x + 9 and 3x-5y=15. Then you could do 3x - 5(-3x+9) = 15. Finally solve for x and plug in x into both equations to see if you get the same y value.
The answer should be (10/3, -1)
The 5.9+58.9= finding a calculator
From this question, you can conclude:
1. There are 3 decimal
2. Decimal1 + decimal2+ decimal3= 2
3. The first decimal is 0.34
If you insert the 3rd into 2nd equation, it will become:
0.34+ decimal2+ decimal3= 2
decimal2+ decimal3= 2-0.34
decimal2+ decimal3= 1.56
If there are no rules regarding the second and third decimal, then you can use this both
1.01 + 0.55
0.78 + 0.78
