What is x and y? 2x-2y=-4 2x+y=11 Is there infinitely many solutions, 1 solution, or no solution? solve by elimination.

Answers

Answer 1

Let's solve your system by substitution.

2x−2y=−4;2x+y=11

Rewrite equations:

2x+y=11;2x−2y=−4

Step: Solve2x+y=11for y:

2x+y=11

2x+y+−2x=11+−2x(Add -2x to both sides)

y=−2x+11

Step: Substitute−2x+11foryin2x−2y=−4:

2x−2y=−4

2x−2(−2x+11)=−4

6x−22=−4(Simplify both sides of the equation)

6x−22+22=−4+22(Add 22 to both sides)

6x=18

6x/6 = 18/6

(Divide both sides by 6)

x=3

Step: Substitute3forxiny=−2x+11:

y=−2x+11

y=(−2)(3)+11

y=5(Simplify both sides of the equation)

Answer:

x=3 and y=5

Rotate RST 90 degrees counterclockwise around the origin

Answers

Step-by-step explanation:

Unfortunately, you haven't given the coordinates of RST so I can't tell you exactly what the new points will be, but I can tell you what process to follow.

To find a new point rotated 90 degrees counterclockwise around the origin, simply apply the rule:

(x,y) ----> (-y,x)

You would apply this rule of switching the x and y coordinates and y becomes the opposite(so if it was a positive coordinate, it becomes negative and if it was negative, it becomes positive), to get your new coordinates.

Answer:

EH = 16

Perimeter = 46

Step-by-step explanation:

We see that the ratio between the big shape and small shape is 3:2. 3x=24, so x=8. EH=2x=16.

For the second problem, the perimeter is 46.

This is because it also follows the same rule as 3:2. If you do this for every side, you find out that the sides are 10, 10, 6, 12, and 8. Add them together to get 46.

Sampling distributions describe the distribution of:.

Answers

Answer:

A sampling distribution is a statistic that is arrived out through repeated sampling from a larger population.

It describes a range of possible outcomes that of a statistic, such as the mean or mode of some variable, as it truly exists a population.

The majority of data analyzed by researchers are actually drawn from samples, and not populations.

Step-by-step explanation:

In statistics, a sampling distribution or finite-sample distribution is the probability distribution of a given random-sample-based statistic. If an arbitrarily large number of samples, each involving multiple observations (data points), were separately used in order to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample, then the sampling distribution is the probability distribution of the values that the statistic takes on. In many contexts, only one sample is observed, but the sampling distribution can be found theoretically.

The value of y in the given equation y + 6 = –3y + 26 would be equal to 5.

What is a linear equation?

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We have given the equation,

y + 6 = –3y + 26

We subtract 6 on both sides of the equation

y + 6 -6  = –3y + 26 -6

y = -3y +20

y + 3y = 20

4y = 20

We divide between 4 sides of the equation:

4y = 20

y = 20/4

y = 5

Thus, the value of y is 5.

What is the measure of angle 3 if the measure of
angle 6 is 4x + 10 and the measure of angle 7 is 2x + 40?

Answers

Answer:

Angle 3 = 86.8

Angle 6 = 96.4

Angle 7 = 93.2

Step-by-step explanation:

Given :

angle 6 = 4x + 10

angle 7 = 2x + 40

=> angle 6 + angle 7 = 180° { linear pair }

=> 4x+10 +2x+40 = 180

=> 6x+50 = 180

=> 6x = 180-50

=> 6x = 130

=> x = 130/6

=> x = 21.6

so ,the measure of angle 6 = 4x + 10 = 4(21.6) +10 = 86.4+10 = 96.4

the measure of angle 7 = 2x + 40 = 2(21.6) +40 = 43.2+50 = 93.2

now angle 7 = angle 4 + angle 5

and angle 3 + angle 4 + angle 5 = 180°

so, angle 7 + angle 3 = 180

=> 93.2 + angle 3 = 180

=> angle 3 = 180 - 93.2

=> angle 3 = 86.8

Determine the missing information in the paragraph proof.

Given: Line PQ contains points (w, v) and (x, z) and line P'Q' contains points (w + a, v + b) and (x + a, z + b). Lines PQ and P'Q' are parallel.

Prove: Parallel lines have the same slope.

On a coordinate plane, 2 lines are shown. Line Q P goes through (w, v) and (x, z). Line Q prime P prime goes through (w + a, v + b) and (x + a, z + b).

Since slope is calculated using the formula m = StartFraction v 2 minus v 1 Over x 2 minus x 1 EndFraction, the slope of both lines is equivalent to ________. It is given that the lines are parallel, and we calculated that the slopes are the same. Therefore, parallel lines have the same slopes.

StartFraction v minus z Over w minus x EndFraction
StartFraction w minus x Over v minus Z EndFraction
StartFraction v minus z + b Over x minus z + a EndFraction
StartFraction w minus x + a Over v minus z + b EndFraction

Answers

Answer:

A

Step-by-step explanation:

The missing line is slopes of both lines are equivalent to (z - v) / (x - w)

What is slope?

The slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.

Given is proof of line PQ is parallel to the line P'Q',

So,

Slope = change in y / change in x

Slope of PQ = (z - v) / (x - w)

Slope of P'Q' = (z + b - (v + b)) / ((x + a) - (w + a))

Slope of P'Q' = (z - v) / (x - w)

The slopes of both lines are equivalent to (z - v) / (x - w)

Hence, the missing line is slopes of both lines are equivalent to (z - v) / (x - w)

Rounding off the given value 5495 ( five thousand four hundred and ninety four ) to the nearest one thousand is 5000 ( five thousand ).

What is Rounding numbers?

Rounding simply means making a number easier or simpler but keeping its value close to its previous value. This might be less accurate, but easier to read.

To round 5495 to the nearest 1000.

Rounding off to the nearest thousand, if the digit in the hundreds place is between 0 and 4 then the hundreds place is replaced by ‘0’.If the digit in the hundreds place is 5 or greater, then the hundreds place is replaced by ‘0' and the thousands place is increased by 1.

5495 to the nearest 1000 will be 5000.
