Okay the answer is 69 because 81-2 is 69
Answer:
-7/13
Step-by-step explanation:
To find the reciprocal of a number, either divide the number by 1 or switch the numerator and denominator
g(x)=2x+3
g(x)=3
use the substitution for g(x)
g(3)=2(3)+3
do the parenthesis first because of PEMDAS
P= parenthesis
E= exponents
M= multiplication
D= division
A= addition
S= subtraction
g(3)=2(3)+3
g(3)=6+3
g(3)=9
Answer:
g(3)=9
Answer:
Okay so i use this all the time for my school so it graphs thing like functions, coordonates it also has a way you can add a table if u need it, to basically use it enter the y in ur equation like y=8x+9 and then the next bar would be x like x=9x+10 things like that and to graph a function u only need one bar and such to graph it that way, i'll put down some examples for you to look at and if u have any specififc questions i can answer those as well, Oh also if u put up 2 equations and only see one line you have to click the zoom out button on the right side of ur screen until u see the line.
Step-by-step explanation:
In the first picture i circled the important parts of the calculator which is the zoom out button, and the colors of the lines, you can also switch the colors if u want to as well, In the second picture it shows how to find the x,y intercepts if thats what you have to do. Whenever the lines intercept on a graph then thats what ur x and y intercepts are. If you have any more questions pls ask and i can answer them!
