Answer:
10 = b
Step-by-step explanation:
Begin by expanding (x + 5)^2
(x + 5)(x + 5)
First: x*x = x^2
Outside: x * 5 (the last term which is a 5)
Inside: 5+ x
Last: 5*5 = 25
x^2 + 5x + 5x + 25
x^3 + 10x + 25
Answer:
The answer is x=6
Step-by-step explanation:
Using the model for the linear equation, y=mx+b, we can plug in (3,7) for x and y to get 7 = (2/3)(3) + b. This means that b = 5.
We can then take our new equation and substitute (x,9) to get 9=(2/3)x+5. If we solve this equation, we get that x=6.
