Answer:

D, 4m+5

Step-by-step explanation:

First, we distribute the positive:

3m+m+5

Now combine like terms:

4m+5

My answer is the same as D so the answer is D

I hope this helps u pls give brainliest and a thx ;)

What is the equation of a line, in Slope Intercept Form, with a slope of 1/3 and passes through the point (9, 7)?

levacccp [35]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have the slope $m=\dfrac{1}{3}\to y=\dfrac{1}{3}x+b$

and point (9, 7). Substitute:

$7=\dfrac{1}{3}(9)+b$

$7=3+b$ <em>subtract 3 from both sides</em>

$4=b\to b=4$

Answer: $y=\dfrac{1}{3}x+4$

A city's current population is 1,000,000 people. It is growing at a rate of 3.5% per year. The equation P=1,000,000(1.035)^x mod

Sloan [31]

To determine the number of years to reach a certain number of population, we need an equation which would relate population and the number of years. For this problem, we use the given equation:

<span>P=1,000,000(1.035)^x

We substitute the population desired to be reached to the equation and evaluate the value of x.

</span>P=1,000,000(1.035)^x
1400000=1,000,000(1.035)^x
7/5 = 1.035^x
ln 7/5 = ln 1.035^x
x = ln 7/5 / ln 1.035
x = 9.78

Therefore, the number of years needed to reach a population of 1400000 with a starting population of 1000000 would be approximately 10 years.
