Answer: f(x)=mx+b
f(x)=x+7
if x=2 then
f(2)=2+7=9
A function is linear if it can be defined by
f(x)=mx+b
f(x) is the value of the function.
m is the slope of the line.
b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
x is the value of the x-coordinate.
Answer:
The vertex of a parabola is (h,k)
Step-by-step explanation:
The vertex form of a parabola is y=a(x-h)^2+k where a is the stretch/compression factor and (h,k) is the vertex. So to find the vertex, you will need (h,k) which represents the horizontal and vertical shift of the parabola
the answer would be 5% because 56 is 20% of 280 and thats 4 years so you divide by 4 which gets you 5%.
Answer:
x 
Step-by-step explanation:
You move the decimal to the right of the first non-zero digit. Count the spaces you moved it, remembering the LARD rule, and that is the power of ten.
30 + .15x = 20 + .20x
10 = .05x
200= x
