Answer:

Parallel

Step-by-step explanation:

-y₁ + y₂\-x₁ + x₂ = m

$\frac{2 + 7}{ -5 + 8} = \frac{9}{3} = 3$

$\frac{0 + 6}{6 - 4} = \frac{6}{2} = 3$

Both rate of changes [slopes] result in three, therefore both lines are parallel.

I am joyous to assist you anytime.

Preeta watches an ant and beetle crawl in a hole in the ground. the beetle is 3/4 inch below ground level. the beetle climbs 1/3

Alex_Xolod [135]

Answer:

1a: $\frac{3}{4}$ + $\frac{1}{3}x$ = $2\frac{1}{2}$

1b: See below

1c: $2\frac{3}{4}$ inches between the beetle and ant

Step-by-step explanation:

1a. To build the equation, we need to see that the beetle started at 3/4th inches below ground level, then "climbed" (which is poor English, it should be descended) a certain distance, and then it ended up at 2 1/2 inches below ground. The distance "climbed" can be represented as 1/3X, where "X" is the ant's current distance. We would do 1/3rd times "X" to figure out how much the beetle climbed down.

So that means, if we added together the starting position of 3/4, plus the distance the beetle descended (1/3X), that would get us TO 2 1/2 inches below ground (the beetle's new current position). So therefore our equation is:

$\frac{3}{4}$ + $\frac{1}{3}x$ = $2\frac{1}{2}$

1b. Solve the equation written above from 1a.

$\frac{3}{4}$ + $\frac{1}{3}x$ = $2\frac{1}{2}$

-3/4 -3/4 [subtract 3/4 to start the process of getting x by itself]

$\frac{1}{3}x$ = 1 $\frac{3}{4}$

*3/1 *3/1 [Multiply Reciprocal to get X by itself]

x= $5\frac{1}{4}$

1c. So we take the position of the ant figured out on 1b (5 1/4 inches), and the new current position of the beetle (2 1/2 inches), and subtract them

5 1/4 - 2 1/2 = $2\frac{3}{4}$

Find the perimeter of a rectangle with a length of 6x+3 and a width of -2x-5.

blsea [12.9K]

The simple way of calculating a perimeter is to add all of the sides.
For a rectangle this would equal 2 x length + 2 x width
P = 2(6x + 3) + 2(-2x - 5)
= 12x + 6 - 4x - 10
= 8x - 4

At a higher level both the length and width must be greater than zero (= zero is a trivial rectangle)
6x + 3 > 0
6x > -3
x > -0.5

-2x - 5 > 0
2x + 5 < 0 (multiplying by -1 reverses the inequality)
2x < -5
x < -2.5

This rectangle cannot exist as x cannot be < -2.5 and > -0.5 at the same time!

Convert the function into intercept form. Show your work. y=-x^2+5x+36

UkoKoshka [18]

Y = -x2 + 5x + 36 → y = -(x2 -5x -36)

→ y = -(x2 - 9x +4x - 36)

→ y = -[x(x-9) + 4(x - 9)]

→ y = -(x - 9)(x + 4)

Your answer would be y=-(x-9)(x+4).

I GIVVVVVVE EEEEEE BRAINLILST

insens350 [35]

Answer:

1/5

Step-by-step explanation:

If you focus on one of the coordinates, for example (10,10) you will notice that 10 divided by 5 equals 2. If you do that on both X and Y it will give you 2. The black shape's top right cordinate is (2,2) which explains why its 1/5...
