Answer:8x^2-4x-5
Step-by-step explanation:just subtract
Short answer: 39
y = 7x - 3
f(x) = y = 7x - 3 Though there are some slight differences between f(x) and y, it is safe to say that f(x) acts (in this case) as a y value. So the question now is what does y(6) mean?
y(6) means exactly the same thing as what f(6) would mean. The both mean that where ever you see an x, put in a 6.
So y(6) means 7x - 3 = 7*6 - 3 = 39
For 10, the slope is 1/2 and the y intercept is 0. For 12 i believe its 4 for both the slope and the y intercept.
Answer:
y= \frac{15}{7}x + 7
not sure if that will work so
y = 15x/7x + 7
