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).

Need help with this question <br><br> 2 + (4h- 1) = 13h<br><br> Need All Steps Plz
vredina [299]

Answer and Step-by-step explanation:

For this equation, we are solving for h.

We are given the equation:

2 + 4h - 1 = 13h

<u>First, we need to </u><u><em>Simplify</em></u><u> the equation.</u>

2 - 1 + 4h = 13h

1 + 4h = 13h

<u>Now, we need to </u><u><em>Subtract</em></u><u> 4h from both sides of the equation.</u>

1 + 4h - 4h = 13h - 4h

1 = 9h

<u>Finally, we </u><em><u>Divide</u></em><u> both sides by 9 to get h.</u>

\frac{1}{9}  = h

<u>h is equal to </u>\frac{1}{9}<u>.</u>

To check your answer, we plug \frac{1}{9} back into the given equation.

2 + 4(\frac{1}{9} ) - 1 = 13(\frac{1}{9} )\\\\\\\\2 + \frac{4}{9} -1 = \frac{13}{9} \\\\\\1 = \frac{9}{9} \\\\1 = 1

<u>I hope this helps!</u>

What is the area of this triangle?
crimeas [40]

Answer: 54cm^{2}

The area of a triangle is given by:

A_{triangle}=\frac{(b)(h)}{2}

Where:

b=9cm is the base of this right triangle

h=12cm is the height of the triangle

Substituting the known values:

A_{triangle}=\frac{(9cm)(12cm)}{2}

Finally, the area of this triangle is:

A_{triangle}=54cm^{2}
