Answer:

y = 1/4x -3/2

Step-by-step explanation:

The "run" (horizontal distance) between the two marked points is 6-(-2)=8.

The "rise" (vertical distance) between the two marked points is 1 -(-1) = 2.

The slope of the line shown is ...

m = rise/run = 2/8 = 1/4

A parallel line will have the same slope.

The y-intercept of the desired line can be found from ...

b = y -mx

For point (2, -1) and slope 1/4, the y-intercept will be ...

b = -1 -1/4(2) = -3/2

Then the equation of the parallel line is ...

y = mx +b . . . . . . . line with slope m and y-intercept b

y = 1/4x -3/2

Answer:

$x=-3 \\and\\ y=2$

Step-by-step explanation:

$x + y = -1$ Equation:1

$4x - 2y = -16$ Equation:2

Solving Equation:1

$x+y=-1$

Subtracting 'y' from both the sides:

$x+y-y=-1-y\\\\x=-1-y$

Putting 'x' in Equation :2

$4(-1-y)-2y=-16\\\\-4-4y-2y=-16\\\\-4-6y=-16$

Adding '4' both the sides

$-6y=-16+4\\\\-6y=-12\\\\y=-12/-6\\\\y=2$

Putting the value of 'y' in equation:1

$x+y=-1$

$x+(2)=-1\\\\x=-1-2\\\\x=-3\\$

The solution is:

$x=-3 \\and\\ y=2$

I will give BRAINLIEST to the correct answer

erica [24]

Answer:

<PCH+<HCK=180-DEGREE BEING IN A STRAIGHT LINE.

3M+58+8M+155=180

11M=180-213

11M=-33

M=-3

SO,

<PCH

3M+58

=3*(-3)+58

=58-9

=49-DEGREE

Find the probability of getting tails on every toss of a coin when the coin is tossed 5 times.

icang [17]

Answer:

1/10, or 10%

Step-by-step explanation:

There are 2 outcomes you can get from one toss, heads and tails. Therefore, if you tossed it once, the probability of landing tails would be 1/2, or 50%. Since you toss it 5 times, you will multiply the probability of one toss by five. 1/2x5 = 1/10, so your probability of landing tails on every toss when thrown 5 times is 1/10, or 10% :)

I would really appreciate it if someone could answer these as i'm really stuc and its due for tomorrow.

1. Round 50.75 to 50 and 0.18 to 0.20.
50 x 0.2 = 10

2) Round 96 to 100 and 0.499 to 0.5
100 divided by 0.5 = 50

3a) Round 8.2 to 8, 6.7 to 7, and 0.46 to 0.50
8 x 7 divided by 0.50 = 112

3b) Round 23.4 to 20, 13.9 to 10, and 0.18 to 0.20
20 x 10 divided by 0.20 = 2,000
