What is the effect on the graph of the linear parent function, f(x) = x, when f(x) is replaced by f(x + 5)?A) The graph of the line becomes steeper.
B) The graph of the line shifts horizontally right 5 units.
C) The graph of the line shifts vertically down 5 units.
D) The graph of the line shifts horizontally left 5 units.

Answers

Answer:

D) The graph of the line shifts horizontally left 5 units.

Adding a number, n, inside of the parenthesis with x would move the parent function n units to the left.

Here are the rules:
F(x + a) shifts a units left.
F(x - a) shifts a units right.

You can see this by taking for example f(x) = x^2 then f(x+5) = (x+5)^2, if you graph y=x^2 and y=(x+5)^2, you will see it is shifted 5 units to the right.

What's the answer to v+9/3=8

Answers

I'm a bit confused about way to write this equation down, so I will solve this both ways, and you will chose whitch you had in mind ;)

$(v+9)/(3)=8$
$v+9=8*3$
$v=24-9$
$v=15$

or:

$v+(9)/(3)=8$
$v+3=8$
$v=8-3$
$v=5$

Shelley compared the number of oak trees to the number of maple trees. she counted 9 maple trees to every 5 oak trees in the beginning of the year. at the end of the year,the new ratio of the number of maple tree to the number of oak trees is 3:11. at the end of the year,there were 132 oak trees . how many more maple tree were then in the beginning of the year than the end of the year? explain

Answers

so at the end of the year maple:oak=3:11 and there were 132 oak so 132=11 units 132/11=12 so there were 3 times 12 maple trees at the end or 36 so 36:132
assuming the units stay the same (1 unit=12) in the biginning of the year there were 108 maple trees
108-36= 72
there were 72 more
