3x -4y=-2

subtract 3x from the left side and subtract it to the right

you get
-4y= -3x -2

divide each side by -4

you get

y= 3/4x- 1/2

y-intercept = - 1/2

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.

natta225 [31]

we have

$2x-2y=6$ ------> equation $1$

$4x+4y=28$ ------> equation $2$

Multiply by $2$ the equation $1$

$4x-4y=12$ ------> equation $3$

Sum equation $2$ and equation $3$

$4x+4y=28\\ 4x-4y=12\\ ------\\ 8x=40\\ x=40/8\\ x=5$

Substitute the value of x in the equation $2$

$4x+4y=28$

$4*5+4y=28\\ 4y=28-20\\ 4y=8\\ y=8/4\\y=2$

therefore

the answer is the option B

$(5,2)$

Name the consecutive (same side) exterior angles and interior angles

konstantin123 [22]

Answer:

Consecutive Interior Angles

Consecutive interior angles equal 180 degrees and they are the ones in between(inside) the parallel lines, so that means that these angles..

∠2+∠9= 180

∠4+∠11= 180

∠6+∠13= 180

∠8+∠15= 180

Consecutive Exterior Angles

Consecutive exterior angles also equal 180 degrees, but they are on the outside of the parallel lines. They are...

∠1+∠10= 180

∠3+∠12= 180

∠5+∠14= 180

∠7+∠16= 180

A college library has five copies of a certain text on reserve. Three copies (1, 2, and 3) are first printings, and the remainin

dezoksy [38]

Answer:

S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }

A ={(4), (5)}

Step-by-step explanation:

Given that:

Among the three copies, (1,2,3) are the first printings, and (4,5) are the second printings.

A student who examines these books in random order stops when a second printing has been selected.

Thus, we can compute the sample space associated with these experiments as:

S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }

Suppose A represents the event that we must examine exactly one book.

Then the outcomes of A are:

A ={(4), (5)}

How would you describe the shape of the normal distribution?

RUDIKE [14]

The shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).

What is a normal distribution?

A normal distribution is a function on some random variables, which represent the set of all those random variables in a symmetrical bell shape about the mean value.

It shows that the probability of occurrence of some data which is distributed over a function is more at or around the mean.

It is also known as probability distribution curve.

The normal distribution has two parameters:

Mean

Standard deviation

What is the shape of the normal distribution?

The normal distribution curve is at it's peak at the mean value. This shows that the probability of occurrence of the data or value is more concentrated or distributed about the mean. It is also symmetric about the mean. As we more further from the mean, we see that the normal distribution curve gradually decreases showing that the probability of occurrence of the data or the values decreases. The shape that this curve forms is like a bell-shaped. So the shape of normal distribution is bell shape.

Hence, the shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).
