Graph the linear equation. 3x−4y=12<br><br> Please show it on a graph

baherus [9]

Answer: The graph is attached.

Step-by-step explanation:

By definition, the line intersects the y-axis when $x=0$ .

Then, in order to find the y-intercept, substitute $x=0$ into the equation and solve for "y":

$3(0)-4y=12\\\\y=\frac{12}{-4}\\\\y=-3$

By definition, the line intersects the x-axis when $y=0$ .

Then, in order to find the x-intercept, you can substitute $y=0$ into the equation and then you must solve for "x". Then you get:

$3x-4(0)=12\\\\x=\frac{12}{3}\\\\x=4$

Knowing that the line passes through the points $(0,-3)$ and $(4,0)$ , you can graph it (The graph is attached).

Answer: choices 1, 4, and 5.

Step-by-step explanation: uhhhh the answers basically explain why. 1 because it's a terminating decimal, 4 because it's a repeating number, and 5 because the square root of 11 is not a perfect square, and is not a repeating or terminating decimal.

Help with the algebra expression.

alexdok [17]

We can rewrite a cube root into a fractional index form.
So, we can rewrite:
$\sqrt[3]{m^{2}n^{5}} = (m^{2}n^{5})^{\frac{1}{3}$
$= m^{\frac{2}{3}} \cdot n^{\frac{5}{3}}$

Answer:

Step-by-step explanation:

I am not quite sure if this is correct.

first I figured out how many minutes per 1 mile: 24

then I figured out how exactly much time 1.5 hours is: 1 hour and 12 minutes. then I subtracted that from 2 hours, knowing that 1.5 hours is 3 miles, I found that there was only 48 minutes remaining in that hour, which would be 24×2, aka 2 miles. so the final answer would be 5 miles, sorry for the run-on sentence. Yet again, I am not quite sure if this is right-
