The curve is a linear equation.

<h3>What type of curve is the given equation?</h3>

It is actually a linear equation, meaning that this is a straight line, not a an actual "curve".

To view the "shape" of the curve, you need to graph it.

You could use a program or do it by hand, to do it by hand, you need to evaluate a lot of points of the equation, and then graph them to see the general behavior of the equation.

In this case, I graphed it with a program, and in the image, you can see that this is a linear equation that decreases as the variable increases.

Is the product of 12 and 3/4 more or less than 12? Please explain answer
denis23 [38]
Hello!!

So the product is when numbers or variables are multiplied together. So if we have 12 * 3/4 then that equals 12/1*3/4=(12*3)/4=36/4=9

So we can see that the product of 12*3/4 is less than 12. We can see this right from the start by noticing that to be at least 12, then 12 would have to be multiplied by at minimum 1 meaning 12*1=12 anything less than 1 would result in a lesser value than 12.

Hope this helps!! Any questions please just ask!! Thank you!!!

During the worst periods of hyperinflation in a certain country, the price of food increased at a rate of 30% per month. State w
Serhud [2]

Answer:

It was an exponential increase

In 3 months, the bill will be $285.61

Step-by-step explanation:

First, this scenario is exponential, because the price of food is increasing with a percentage, based on the price that it was the previous amount.

Next, to find what the bill will be in 3 months, an equation needs to be made representing the situation.

Use the standard exponential equation: y = ab^x, where a is the initial amount, b is the growth rate, and x is the amount of time.

Plug in the values we know:

y = 130(1.3)^3

Solve for y

y = 285.61

So, 3 months later, the bill will be $285.61

A car dealership has SUVs and sedans in a ration of 5:9. How many sedans does the car dealership have if there are 140 SUVs
Elza [17]

To solve this, all you need to do is compare the ratio to the amount of SUVS there are.

5/9 (SUVs to sedans)

140/? (SUVs to sedans)

140 ÷ 5 = 28

9 x 28 = 252

140/252

There are 252 sedans in the car dealership! :D
