Write in the line in slope-intercept form given the slope of 1/3, through the point (-6,9)
JulsSmile [24]

Answer:

<h2>         y = ¹/₃x + 11 </h2>

Step-by-step explanation:

A line passing through point (x₁, y₁) with the slope of m in point-slope form:

 y - y₁ = m(x - x₁)

m = ¹/₃

(-6, 9)      x₁ = -6,  y₁ = 9

So:

y - 9 = ¹/₃(x - (-6))

y - 9 = ¹/₃(x + 6)     ←    point-slope form

y - 9 = ¹/₃x + 2        {add 9 to both sides}

y = ¹/₃x + 11        ←  slope intercept form

velikii [3]
<span>First, we need to know that the current recommended daily allowance of Vitamin E is 15 milligrams. If Leena ate four tablespoons of peanut butter, thus receiving only 6 milligrams, then we can determine the percentage by first dividing 100 into 15 parts (which gives us 6.66), and then multiply that answer by 6 (6 x 6.66), which gives us precisely 40. Thus, the answer is 40 percent.</span>

jeyben [28]

Solution

Given the population function to be;

P(t)=\frac{250t}{t+25}

When P(t) = 150

\begin{gathered} \Rightarrow\frac{250t}{t+25}=150 \\  \\ \Rightarrow250t=150(t+25) \\  \\ \Rightarrow250t=150t+3750 \\  \\ \Rightarrow250t-150t=3750 \\  \\ \Rightarrow100t=3750 \\  \\ \Rightarrow t=37.5\approx38 \end{gathered}

1803 + 38 = 1841.
