Step 1: remove parentheses
1-7+2.5
step 2:simplify 1-7 to -6
-6+2.5
step 3 :simplify
-3.5
the answer is -3.5
P(t) = [ 64/ (1 + 11.e⁽⁻⁰ ⁰⁸t⁾]
In 1991, t = 1, hence:
P(t) = [ 64/ (1 + 11.e⁽⁻⁰ ⁰⁸ˣ¹⁾] = 5.7377 billion or rounded 5.74 billion
(Answer A)
Just asking. How are we supposed to answer this without some sort of picture with a graph or something? :/
Hey there! :)
We're simply just trying to convert "-18x + 2y ≥ -13" into slope-intercept form.
First, we need to know what slope-intercept form is.
Slope-intercept form is : y=mx+b , where m=slope and b=y-intercept.
In order to convert our given equation into slope-intercept form, we have to isolate "y."
We can do this by adding 18x to both sides.
2y ≥ 18x - 13
Then, divide both sides by 2.
2y ÷ 2 = (18x - 13) ÷ 2
Simplify.
y = 9x - 13/2
Convert -13/2 into a mixed fraction.
So, simply divide -13 by 2.
-13 ÷ 2 = -6.5
Plug in -6.5 into where -13/2 was.
y = 9x - 6.5
Therefore, your answer is C : y ≥ 9x - 6.5
~Hope I helped!~
