Using translation concepts, the equation for function g is given by:

g(x) = 7x/3 + 1.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

Supposing that we have a function f(x), a horizontal compression by a factor of a is equivalent to finding f(ax).

In this problem, the function is:

f(x) = 7x + 1.

For the horizontal compression by a factor of 1/3, we have that:

g(x) = f(1/3x) = 7x/3 + 1.

This is literlly a quiz due in a hour plz help I'll make it 25 points.

Answer:

Line JL=8

Step-by-step explanation:

Think of side KL as a, JK as b, and JL as c.

According to the 30-60-90 degree angles rule, if a is equal to one, then b would be equal to √3, and c would be equal to 2. Using this in your situation, we can find out that JL is 8 by dividing 4√3 by √3 to get side KL which would be 4, and multiply that by 2 to get side JL which is 8. Good luck on the quiz!

Over the course of one day, a store owner determined that 80% of customers bought a drink and 30% of customers bought a snack. I

Answer:

200

Step-by-step explanation:

Let the total number of customers that day be "x"

30% of total customers bought a snack and that is 120.

So we can say:

30% of total (x) is 120

Note: 30% converted to decimal is 30/100 = 0.3

This can be translated to an algebraic equation as:

0.3x = 120

Now, we can solve for x, the total customers:

0.3x = 120

x = 120/0.3

x = 400

Since, 80% bought drink, we find 80% of 400:

80% = 80/100 = 0.8

0.8 * 400 = 320

The store sold 320 drinks and 120 snacks. So drinks outweigh snacks be:

320 - 120 = 200

So,

200 more drinks than snacks
