Answer:
f(0) = -3
x increases by 1 f(x) increase by 2
f(x) = 2x -3
Step-by-step explanation:
Looking at the graph
f(0) means when x =0 the value of y = ?
when x = 0 y = -3
f(1) means when x = 1 y = ?
When x = 1 y = -1
y increased from -3 to -1 so it increased by 2
f(x) = ax+b where a is the increase and b is the value at x =0
f(x) = 2x -3
Answer:
y = 5x-5
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 10-5)/(3-2)
= 5/1
=5
Using slope intercept form
y = mx+b
y = 5x+b
Substituting a point into the equation
5 = 5*2+b
5 = 10+b
Solving for b
5-10 = b
-5 =b
y = 5x-5
Answer:
Step-by-step explanation:
perimeter = 36
w = 8
l = 10
Area = 80
Answer:
the answer is 16.5 or when runner becomes 17.
Step-by-step explanation:
The product of a number and five
= the number is always replaced by a variable. and I used
less than the number is 66
=
you divide both sides by 4 since we want X to stand alone .
