Answer:

4x+4

Step-by-step explanation:

you have to combine like-terms:

              7x plus -3x which gives you 4x. All that there is left is the 4. you cant combine anything else because 4x and 4 are not like-terms. so that leaves you with 4x+4

If f(x) = 2x + 3 and g(x) =4x - 1, find f(4).
fomenos

Solve the "f" function with substitute 4 and solve the "g" function with what we get for the "f" function.

f(4) = 2(8) + 3

f(4) = 16 + 3

f(4) = 19

g(19) = 4(19) - 1

g(19) = 76 - 1

g(19) = 75

Best of Luck!

Help with part A and part B
Vitek1552 [10]
A. You can use y=mx+b to find the rate of change of a bushel corn in the current year. The rate of change would be y=8x.

B. One bushel is worth 8$ (24/3 = 8) in the current year, and in the previous year one bushel was worth 7$ (21/3= 7). Therefore there was a 1$ raise from the previous year to the current year.
