Answer:
f(x) = 5x - 5
Step-by-step explanation:
Let the equation of the linear function is,
f(x) = mx + b
Here, m = Slope of the graph
b = y-intercept
Slope of the line passing through 
and 
is given by,
m = 
From the table attached,
Slope of the line passing through (2, 5) and (6, 25) will be,
m = 
m = 5
Equation of the linear function will be,
f(x) = 5x + b
Since, a point (10, 45) lies on the function,
45 = 5(10) + b
b = 45 - 50
b = -5
Equation of the linear function will be,
f(x) = 5x - 5
Answer:
Total interest =$1296
Step-by-step explanation:
Kevin invested $8,000 for one year at a simple annual interest rate of 6 percent
Simple interest = 
P=8000, n=1 year and r=6
interest = 
Interest = 480 dollars
P= 10000, t=1, r=8%=0.08, n=2 for semiannually
Interest = 10816- 10000=816
Total interest = 
Goal: solve for y. First step: Multiply out 5(y+2) and also 4(2y-1):
5y + 10 and 8y - 4
Then your original <span>5(y+2) = 13+ 4(2y-1)
becomes 5y + 10 = 13 + 8y - 4
Combining the y terms: </span>10 = 13 + 3y - 4
Simplifying the right side: 10 = 3y + 9
Subtracting 9 from both sides: 1 = 3y. Solving for y: y = 1/3
Answer:
9
Step-by-step explanation:
You should do 20% which is .2 in decimal form, and then multiply 45 by .2 and you will get 9.
