Slope of the line is 0.

Step-by-step explanation:

Step 1: Calculate the slope of the line using the equation (y2 - y1)/(x2 - x1)

x1 = -4, x2 = 5, y1 = 3, y2 = 3

⇒ m = (3 - 3)/(5 - -4) = 0/9 = 0

Solve the system of equations. 2y+7x=−5 5y−7x=12

We can solve this by substitution method.

Look at the second equation. If we rearrange to find 7x, we can substitute in the value into the first equation.

$5y-7x=12$

$5y-7x-12=0$

$5y-12=7x$

Therefore, $7x=5y-12$

Now replace the 7x in the first equation with 5y - 12:

$2y+7x=-5$ (substitute in 7x = 5y - 12)

$2y+(5y-12)=-5$

$7y-12=-5$

$7y=7$

$y=1$

Now that we know y, we can find x by substituting in y = 1 into any equation we want. I will use the equation: 7x = 5y - 12

$7x=5y-12$ (substitute in y = 1)

$7x=5(1) -12$

$5x=5-12$

$7x=-7$

$x=-1$

Helena wants to paint a box in the shape of a cube with sides that are 18 inches long. what is the surface area that Helena will

yan [13]

Answer:

1944 Inches Squared

Step-by-step explanation:

Surface area Formula for a Cube:

$A = 6a^2$

The "edge", which is also the side, is 18 inches.

$a = 18$

Solve the formula.

$A= 6a^2 = 6(18)^2 = 6 * 18^2\\18^2 = 324\\324 * 6 = 1944\\A=1944$

The cube's surface area should be 1944 square inches.
