Graph the linear equation. 3x−4y=12 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 2 + (4h- 1) = 13h 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

First, we need to Simplify the equation.

2 - 1 + 4h = 13h

1 + 4h = 13h

Now, we need to Subtract 4h from both sides of the equation.

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

1 = 9h

Finally, we Divide both sides by 9 to get h.

$\frac{1}{9} = h$

h is equal to $\frac{1}{9}$ .

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

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

I hope this helps!

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:

$A_{triangle}=54cm^{2}$
