Write the equation of the line that goes through the point (-2, 8) with a slope of 1/2

Mathematics

Answer:

The answer is Y = 1/2x + 9

Step-by-step explanation:

The general equation with a slope and intercept is:

y=mx+b

We are given a slope of 1/2, which represents the "M" part of the equation.

So we have:

Y = 1/2x + b

We do not know what "b" is, so the equation is not complete.

We plug in "-2" for X and "8" for Y:

8 = 1/2 (-2) + b

b = 9

So, the full equation is: Y  = 1/2x + 9

Write the expression in complete factored form<br><br> 4u^2(a-3)+q(a-3)
Sauron [17]

[ Answer ]

\boxed{\bold{4au^{2} \ - \ 12u^{2} \ + \ aq \ - \ 3q}}

[ Explanation ]

  • Factor: 4u^{2}(a - 3) + q(a - 3)

-------------------------------------

  • Expand 4u^2\left(a-3\right): 4au^2-12u^2

4au^2-12u^2+q\left(a-3\right)

  • Expand

q\left(a-3\right): aq-3q

  • Answer

4au^2-12u^2+aq-3q

\boxed{\bold{[] \ Eclipsed \ []}}

The population of turtles is doubling every 3 months. If there are 400 turtles now, how many will there
QveST [7]

First we need to know how many months is 2 years. To answer that we multiply the number of months in a year by 2 and get 48 months.

Every 3 months the population of turtles doubles, but to get how many times the population doubles, you need to divide 48 months by 3 to get 16.

So population of 400 will get <u>doubled</u> 16 times in the following <u>two</u> years.

We construct the following equation where p is the final population,

p=400\cdot2\cdot16=\boxed{12800}

Hope this helps. :)
