What is the equation of a line, in general form, with a slope of -2 and a y-intercept of 8? x + 2y - 8 = 0 2x + y - 8 = 0 2x - y + 8 = 0

Answers

Answer 1

Answer: y=mx+b
m=sloe
b=yint
given
slope=-2
yintercept=8

y=-2x+8
add 2x to both sides
2x+y=8
minus 8 both sides
2x+y-8=0

Answer 2

Answer: y= -2x +8 is slope intercept form. To change it to standard form you have to move the x to the left side. Add 2x to both sides. Then move the 8 to the left side so subtract 8 from both sides.
2x + y -8=0
The second one is correct

Which percent would represent an event that is very unlikely?

Answers

Answer=12%

The lower the percent, the more unlikely that the event will happen. Since 12% is the lowest percent, it is also the most unlikely of the options.

90 percent would be right

1. Divide. Assume the denominator does not equal zero.
(12x^2y-6xy+4x^2)/(2xy)

Answers

To divide a polynomial by a monomial, divide each term on the top by the denominator:(12x^2y/2xy) - (6xy/2xy) + (4x^2/2xy)Reduce each fraction separately:6x - 3 + 2x/y

Answer:

True

Step-by-step explanation:

Start by narrowing the equasions down, add all the numbers together:

1s + 1s + 1s + 1s = 4s

4s = 4s

Both equasions are equivelent to 4s, so the answer would be True.

If you had trouble understanding that, here is another way:

First lets set a control number for s, like 3. then we are going to place the control into the equasion:

1(3) + 1(3) + 1(3) + 1(3)

4(3)

Now solve:

1(3) + 1(3) + 1(3) + 1(3) = 12

4(3) = 12

Both equasions are equivelent to 12, so the answer would be True, they are equivelent.

Answers

Argh! My answer was erased!

We need to cut a 15m rope into 20 equal pieces. Written mathematically, it is as follows:
15/20 = length of rope segment in meters (a)
15/20 = a

Simplify
3/4 = a

In meters, each rope segment is 3/4m long. But, we don't want meters. We want centimeters.

100 cm = 1 m

3/4(100) = length of rope segment in centimeters (x)
3/4(100) = x

300/4 = x
75 = x

Each segment of rope is 75 cm long.

The rope needs to be cut into 20 pieces, so 15/20, this will give you 3/4 of a meter per piece. Multiply 100 (100 cm in a meter), .75*100= 75 centimeters in a piece...
