I need your HELPTom knows that in his school 10 out of every 85 students are left handed. There are 391 students in Tom's school. How many students in Tom's school are left-handed?

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the liketerms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can use a proportion to solve the problem:

10 left-handed students out of 85 total students is equivalent to x left-handed students out of 391 total students:

10/85 = x/391

To solve for x, we can cross-multiply:

85x = 10 x 391

Then divide both sides by 85:

x = (10 x 391) / 85

Simplifying the right-hand side gives:

x = 46

Thus,

There are 46 left-handed students in Tom's school.

Do 391 ÷ 85 to get 4.6
Then 85 × 4.6 = 391
So 10 × 4.6 =46
So there are 46 kids in Toms school that are eft handed out of every 391 students.

I have no idea how to graph g(x)..or why f(x) is relevant..... Steps would be helpful!! I got a final twomorrow ;-;

Answers

When you derive a function from another using the transformation

$g(x) = f(x+k)$

you're translating the graph of the parent function f(x) horizontally.

More specifically, you translate the graph k units to the left if k is positive, k units to the right if k in negative.

So, starting from the graph of f(x), you have that the graph of

$g(x) = f(x+3)$

is the same graph of f(x), but shifted 3 units to the left.
