The Slope Formula is \frac{y2-y1}{x2-x1}
Given the points (-4,8), (-3,-6)
\frac{-6-8}{-3+4} = \frac{-14}{1} =-14

2x-3y=0 in slope intercept form, show all steps please!
Ierofanga [76]

In <em>slope-intercept form</em>, the <em>y</em> is isolated or

by itself on the left side of the equation.

Start by subtracting 2x from both sides and we have -3y = -2x.

Then we divide both sides by -3 to get <em>y = 2/3x</em>.

Work is provided in the image below.

In order to fence a garden, the rowan family needs 64 feet of lumber. The garden at the correas house will need to be 100% large
aliina [53]

Answer:

128 feet of lumber

Step-by-step explanation:

In order to fence a garden, the rowan family needs 64 feet of lumber. The garden at the correas house will need to be 100% larger. How man feet of lumber will the correas need?

Step 1

We calculate how many feet larger

Hence:

64 × 100%

= 64 feet

Step 2

How many feet of lumber will the correas need:

= 64 feet + 64 feet

= 128 feet

Let f(x) = Square root x. Find g(x), the function that is f(x) shifted up 7 units and left 1 units.
Rudik [331]

~\hspace{10em}\textit{function transformations} \\\\\\ \begin{array}{llll} f(x)= A( Bx+ C)^2+ D \\\\ f(x)= A\sqrt{ Bx+ C}+ D \\\\ f(x)= A(\mathbb{R})^{ Bx+ C}+ D \end{array}\qquad \qquad \begin{array}{llll} f(x)=\cfrac{1}{A(Bx+C)}+D \\\\\\ f(x)= A sin\left( B x+ C \right)+ D \end{array} \\\\[-0.35em] ~\dotfill

\bullet \textit{ stretches or shrinks horizontally by } A\cdot B\\\\ \bullet \textit{ flips it upside-down if } A\textit{ is negative}\\ ~~~~~~\textit{reflection over the x-axis} \\\\ \bullet \textit{ flips it sideways if } B\textit{ is negative}\\ ~~~~~~\textit{reflection over the y-axis} \\\\ \bullet \textit{ horizontal shift by }\frac{ C}{ B}\\ ~~~~~~if\ \frac{ C}{ B}\textit{ is negative, to the right}\\\\ ~~~~~~if\ \frac{ C}{ B}\textit{ is positive, to the left}

\bullet \textit{ vertical shift by } D\\ ~~~~~~if\ D\textit{ is negative, downwards}\\\\ ~~~~~~if\ D\textit{ is positive, upwards}\\\\ \bullet \textit{ period of }\frac{2\pi }{ B}

keeping in mind that template, let's take a looksie

f(x) = \sqrt{x}\implies f(x) = A\sqrt{Bx + C}+D\implies f(x) = 1\sqrt{1x+0}+0 \\\\\\ \begin{cases} D = \stackrel{\textit{shifted up}}{+7}\\ C = \stackrel{\textit{left shift}}{+1} \end{cases}~\hspace{4em}g(x) = 1\sqrt{1x+1}+7\implies g(x) = \sqrt{x+1}+7
