A pie was cut into 8 equal slices. If Ruben ate 3/4 of the pie, how many slices did he ate? Explain your answer using a number line and words.

Answers

Answer:

Step-by-step explanation:

A pie was cut into 8 equal slices. Ruben ate 3/4 of the pie.

We have tell how many slices Ruben ate.

Since a pie was cut in 8 pieces that means 1 piece is 1/8th part of pie.

Since Ruben ate 3/4 of pie that means 6/8 of pie was finished by Ruben.

This clearly says that out of 8 pieces 6 pieces Ruben has eaten.

If Ruben ate 3/4 of the pie, that means that he ate 6/8 of it, because 3/4 = 6/8, that is, he ate 6 of the 8 slices of the pie.

If f(x) = 2x + 3 and g(x) = x2 + 1,find f(g(3)).

Answers

Answer:

The value of f(g(3)) is 23.

Step-by-step explanation:

The given functions are

$f(x)=2x+3$

$g(x)=x^2+1$

We have to find the value of f(g(3)).

Substitute x=3 in the function g(x) to find the value of g(3).

$g(3)=3^2+1=9+1=10$

$f(g(3))=f(10)$ [g(3)=10]

Substitute x=10 in the function f(x) to find the value of f(10).

$f(10)=2(10)+3=20+3=23$

Therefore the value of f(g(3)) is 23.

Hello,

f(g(3))=f(3²+1)=f(10)=2*10+3=23

Find an equation for the family of linear functions with slope 2 and sketch several members of the family

Answers

f(x)=2x+b. the general eqtn is y=2x+b where b can be +ve or -ve. If you draw y = 2x, you get a line of slope 2, passing through the origin. The line y = 2x+3 is parallel to y = 2x, and cuts the y-axis at y = 3. Similarly, the line y = 2x-1 is parallel to y = 2x, and cuts the y-axis at y = -1. You do not need any points to sketch them on our graph: the lines you draw must just be parallel to y = 2x
