Use the elimination method to solve the system of equations.Choose the correct ordered pair. -x + y -2 , 2x -3y = 4​

Answers

Answer:

To use the elimination method one coefficient of either x or y must be the same number with opposite signs, so the ordered pair is (-10, -8)

Step-by-step explanation:

2(-x+y=2) Make one of the coefficients equal, with opposite signs.

2x-3y=4  Combine equations.

-y=8 Solve, y=-8

Then find x, -x-8=2

-x=10, so x= -10

You are cutting pieces of fabric for a craft project. You need three pieces that measure 6 2/3 inches, 4 1/2inches, and 3 5/8inches.
What is the total length of fabric that you need ?

Answers

Answer:

You need 14 19/24 inches of fabric

Step-by-step explanation:

We'll need a common denominator between 2/3, 1/2, and 5/8. 24 is the least (lowest) common denominator.

3 x 8 = 24, so we multiply the numerator and denominator by 8 and  6 2/3 becomes 6 16/24ths

2 x 12 = 24, so we multiply the numerator and denominator by 12, and 4 1/2 becomes 4 12/24

8 x 3 = 24, so we multiply the numerator and denominator by 3, and 3 5/8 becomes 3 15/24.

Now we are adding 6 16/24 + 4 12/24 + 3 15/24

6 16/24 + 4 12/24 + 3 15/24 = 6 + 4 + 3 + 16/24 + 12/24 + 15/24

= 13 + 43/24 = 14 19/24

In the formulae below, make x the subject:
1. a) P = 2mx​

Answers

Answer:

x = P/2m

Step-by-step explanation:

x is the subject of the formula, and we can express it as: x = P / (2m)

How make x the subject

To make x the subject in the formula P = 2mx, we can rearrange the equation to isolate x on one side.

Starting with the equation:

P = 2mx

To solve for x, divide both sides of the equation by 2m:

P / (2m) = (2mx) / (2m)

This simplifies to:

P / (2m) = x

Therefore, x is the subject of the formula, and we can express it as:

x = P / (2m)

The points that would make a rectangle with lines that are parallel with the x axis would be (1,2) and (5,4) (represented by the red points)

As you can see the points added had created a rectangle with sides that are parallel with the x axis

At the 0.05 level of significance, it can be concluded that the proportion of the population in favor of candidate A is

Answers

Answer:

0.2307 > 0.05, which means that we accept the null hypothesis, that is, that the population proportion in favor of candidate A is close to 0.79, that is, it is not significantly more than 0.79.

Step-by-step explanation:

We are interested in determining whether the proportion of the population in favor of Candidate A is significantly more than 79%.

This means that the null hypothesis is:

[tex]H_{0}: p = 0.79[/tex]

And the alternate hypothesis is:

[tex]H_{a}: p > 0.79[/tex]

We know that the p-value is 0.2307. At the 0.05 level of significance, it can be concluded that the proportion of the population in favor of candidate A is?

0.2307 > 0.05, which means that we accept the null hypothesis, that is, that the population proportion in favor of candidate A is close to 0.79, that is, it is not significantly more than 0.79.

Answer:

m∠A = 130

Step-by-step explanation:

Here, In a given figure

m∠A = 2x - 30°

Now, we know that the sum of all angle is 180° on a straight line

So,

2x - 30° + 50° = 180°

2x + 20° = 180°

2x = 180° - 20°

2x = 160°

x = 160° ÷ 2

x = 80°

Here, we get the value of x is 80°

Now,

m∠A = 2x - 30°

m∠A = 2(80°) - 30°

m∠A = 160° - 30°

m∠A = 130

Thus, m∠A = 130

Imagine looking for a certain angle whose cosine is positive and whose sine is negative.

Part 1: Name the two quadrants in which cosine is positive.

Part 2: Name the quadrants in which sine is negative.

Part 3: Use the information in parts a and b to identify the quadrant in which cosine is positive and sine is negative.

Part 4: Write down one angle, in degrees, that has a negative sine and a positive cosine.

Part 5: Using your calculator, confirm your choice by writing the cosine of your angle and the sine of your angle below.

Answers

The two quadrants in which cosine is positive are the first quadrant (Q1) and the fourth quadrant (Q4).

How to explain the information

Part 2: The quadrants in which sine is negative are the third quadrant (Q3) and the fourth quadrant (Q4).

Part 3: Based on the information from parts 1 and 2, the quadrant in which cosine is positive and sine is negative is the fourth quadrant (Q4).

Part 4: One angle that has a negative sine and a positive cosine in the fourth quadrant is 135 degrees (or 3π/4 radians).

Part 5: Using a calculator, we can confirm the values of cosine and sine for 135 degrees:

Cosine of 135 degrees: cos(135°) ≈ -0.7071 (rounded to four decimal places)

Sine of 135 degrees: sin(135°) ≈ -0.7071 (rounded to four decimal places)
