Find two solution of linear equation 5x-4y = 8

Mathematics
1 answer:
Fudgin [204]2 years ago
3 0

Answer:

Step-by-step explanation:

5x-4y=8\\-4y=-8-5x\\4y=8+5x\\y=(\frac{8+5x}{4} )

let us assume x to be as x=0

then substitute x value in above equation

 y=\frac{(8+0)}{4} \\y=2

let x= -4

y= \frac{(8-4)}{4} \\y=1

therfore, the solutions of the equation 5x-4y=8 is (0,2) and (-4,1)

5. Two vertices of a rectangle are (8,-5) and (8,7). If the area of the rectangle is 72 square units, name the possible location
Phantasy [73]

Answer:

<h3>#5</h3>

<u>Given vertices:</u>

  • (8, -5) and (8, 7)

These have same x-coordinate, so when connected form a vertical segment.

<u>The length of the segment is:</u>

  • 7 - (-5) = 12 units

The area of the rectangle is 72 square units, so the horizontal segment has the length of:

  • 72/12 = 6 units

<u>Possible location of the remaining vertices (to the left from the given):</u>

  • (8 - 6, -5) = (2, -5)

and

  • (8 - 6, 7) = (2, 7)
<h3>#6</h3>

<u>Similarly to previous exercise:</u>

  • (5, -8) and (5, 4) given with the area of 48 square units

<u>The distance between the given vertices:</u>

  • 4 - (-8) = 12 units

<u>The other side length is:</u>

  • 48/12 = 4 units

<u>Possible location of the other vertices (to the right from the given):</u>

  • (5 + 4, -8) = (9, -8)

and

  • (5 + 4, 4) = (9, 4)

The product of the slopes of perpendicular lines equals what?
d1i1m1o1n [39]

If two non-vertical lines are perpendicular, then their slopes are opposite reciprocals giving you -1.

:) Hope this helps.
