What are you specifially looking for? simplified it would be 10 and as a fraction 10 over 1

Factor the equation

Art [367]

Answer:

y = (x + 4)²

Step-by-step explanation:

Given equation is,

y = x²+ 8x + 16

By using identity (a + b)² = a² + 2ab + b²

y = x² + 2(4)(x) + 4²

Here a = x and b = 4

y = (x + 4)²

Therefore, factored form of the given equation is y = (x + 4)²

What is the equation of the line that passes through the points (-1, 7) and (2, 10) in Standard Form?

Usimov [2.4K]

bearing in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

$\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{7})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{10}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{10-7}{2-(-1)}\implies \cfrac{3}{2+1}\implies \cfrac{3}{3}\implies 1$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-7=1[x-(-1)]\implies y-7=x+1 \\\\\\ y=x+8\implies \boxed{-x+y=8}\implies \stackrel{\textit{standard form}}{x-y=-8}$

just to point something out, is none of the options, however -x + y = 8, is one, though improper.

Answer:

31 people

Step-by-step explanation:

think of it like a line,

first person at zero then add 3 feet per person so...

1 + 90/3 = 31 people

kinda funny that the problem isnt accounting for the size of the people
