I'm assuming that when you wrote "(7x/2-5x+3)+(2x/2+4x-6)," you actually meant "<span>(7x^2-5x+3)+(2x^2+4x-6).  Correct me if I'm wrong here.

</span><span>+(7x^2-5x+3)
</span><span>+(2x/2+4x-6)
-------------------
=9x^2 - x - 3 (answer) </span>

Tell whether (5, 2) is a solution of x - y &lt; 0.
meriva

Your points: (5,2)

Your inequality: x - y < 0

Plug 5 in for x and y in for 2

5 - 2 < 0.

Simplify the left side

3 < 0.

3 is not less than 0

(5,2) is not a solution of x - y < 0

1. 50%
2. 25%
3. 60%
Example: What is 10% of 150?

Convert the problem to an equation using the percentage formula: P% * X = Y
P is 10%, X is 150, so the equation is 10% * 150 = Y
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10
Substitute 0.10 for 10% in the equation: 10% * 150 = Y becomes 0.10 * 150 = Y
Do the math: 0.10 * 150 = 15
Y = 15
So 10% of 150 is 15
Double check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 = 15

A population is increasing 4% per year. Identify the growth factor that could be used to model the population.
polet [3.4K]

The growth factor that could be used to model the population will be 1.04. Then the correct option is D.

<h3>What is an exponent?</h3>

Consider the function:

y = a (1 ± r) ˣ

Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

If there is a plus sign, then there is exponential growth happening by r fraction or 100r %.

If there is a minus sign, then there is exponential decay happening by r fraction or 100r %.

The population is increasing by 4% per year.

Then the growth factor that could be used to model the population will be

Growth factor = (1 + 4%)

Growth factor = (1 + 0.04)

Growth factor = 1.04

The growth factor that could be used to model the population will be 1.04.

Then the correct option is D.

More about the exponent link is given below.
