To get the total price multiply the cost of the book by 1 + sales tax rate:
7% as a decimal = 0.07
13.50 x 1.07 = $14.45
I think the answer is f(2)=6 , but I'm not too sure. Hope this helped somehow!
Answer: 10pi
Step-by-step explanation:
C = 2(pi)r
r = 5
2*(pi)*5 = C
10pi = C is the exact answer
If we make 3.14 for the pi substitution, then:
2*3.14*5=C
31.5 = C
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c )
Given
3y - 3x = 21 ( add 3x to both sides )
3y = 3x + 21 ( divide all terms by 3 )
y = x + 7 ← in slope- intercept form
Slope intercept form is the form of y=mx+b. Your m is the slope, and the b is your starting point. To find this, you can start at the bottom, and go to the next point it passes through. It is alway rise over run. Rise is your y, x is your run, so it is always y/x. If you need help finding the slope, use the slope formual, which is y₂-y¹/x₂-x₁. You can use any of the points on here to get your slope... As for the B, well... I can't really help you on that. Sorry! But I hope this helps! :)
