Answer:
f(x)=7
Step-by-step explanation:
Plug in x=2 to the equation.
f(x)=5(2)-3
f(x)=10-3
f(x)=7
Round up if the previous digit is 5 or above, leave it the same (only the hundreth digit, erase all the other thousandths and such) if it is 4 or below
Step-by-step explanation:
Use the Pythagorean Theorem: a^2+b^2=c^2
We can set up the equation like this: 11^2+y^2=61^2
= 121+y^2=3,721
=y^2=3600
= y = 60
I did the first one.
a. The equation that you need to get DF.
b. Substitute the values in the equation.
c. Add up the rs and the numbers (to simplify).
d. divide both sides by 5 to get r.
e. The value of r is given.
