What is the slope between the points (3,-4)&(7,6)?
olchik [2.2K]

Answer: The slope is \frac{5}{2}

Step-by-step explanation:

1. You need to apply the following formula for calculate the slope:

m=\frac{y_{2}-y_1}{x_{2}-x_1}

2. Given the points, (3,-4) and (7,6), you have:

y_{2}=6\\y_1=-4\\x_{2}=7\\x_{1}=3

3. Substitute these values into the formula for calculate the slope, as following:

m=\frac{6-(-4)}{7-3}\\m=\frac{10}{4}

4. Simplify the result. Therefore, you obtain that the slope is:

m=\frac{5}{2}

Round each number to the specified place
hammer [34]
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).


If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).

207,689\approx210,000\\\\507,378\approx1,000,000\\\\3,422,087\approx3,422,000\\\\19,499,890\approx19,000000

Find the inverse of the function
lozanna [386]

as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.

\stackrel{h(x)}{y}~~ = ~~6\sqrt[3]{2x+5}-1\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~6\sqrt[3]{2y+5}-1} \\\\\\ x+1=6\sqrt[3]{2y+5}\implies \cfrac{x+1}{6}=\sqrt[3]{2y+5}\implies \left( \cfrac{x+1}{6} \right)^3=\left( \sqrt[3]{2y+5} \right)^3

\left( \cfrac{x+1}{6} \right)^3=2y+5\implies \left( \cfrac{x+1}{6} \right)^3-5=2y\implies \cfrac{\left( \frac{x+1}{6} \right)^3-5}{2}=y \\\\\\ \cfrac{\left( \frac{x+1}{6} \right)^3}{2}-\cfrac{5}{2}=y\implies \cfrac{~~ \frac{(x+1)^3}{6^3}~~}{2}-\cfrac{5}{2}=y\implies \cfrac{(x+1)^3}{432}-\cfrac{5}{2}=\stackrel{y}{h^{-1}(x)}
