Answer:

15 cm

Step-by-step explanation:

If we have two sides of a parallelogram in the ratio 5:4, then the other two sides must also be in the same ratio.

If the perimeter is 54, we can create the following equation regarding the length of each side

$5x+4x+5x+4x=54\\\\18x=54\\\\x=3$

As our value for x is 3, and we know that the value for the larger side is 5x, we can simply plug in x to get the length of the larger side

$5x\\\\5(3)\\\\15$

What is the slope of the line that is perpendicular to a line whose equation 3y=-4x+2?

Zarrin [17]

The slopes of lines perpendicular to each other are opposite reciprocals. So, if you are given that the slope of a line is 3 and need to find the slope of a line perpendicular to that line, you'd flip that number around and negate it, leaving you with -1/3.

To find the slope of the given line, first get it into slope-intercept form (y - mx + b, where m is the slope and b is the y-intercept).

3y = -4x + 2
y = -4/3x + 2/3

The slope is -4/3. To find the slope of a perpendicular line, find its opposite reciprocal. It is 3/4.

Answer:
3/4 (the first option)

Hello! So, Given the equation y = 2x - 8, what is the slope and the y-intercept? Please help with a good explanation of how you

elena55 [62]

Answer:

m = 2 and b = -8.

Step-by-step explanation:

One of the most commonly used equations of straight lines is y = mx + b, where m is the slope and b is the y-intercept.

Comparing the given y = 2x - 8 to y = mx + b, we see that m = 2 and b = -8.
