Two lines, A and B, are represented by the equations given below:

Line A: y = x − 6
Line B: y = 3x + 4

Which of the following shows the solution to the system of equations and explains why?

(−5, −11), because the point satisfies both equations
(−5, −11), because the point does not lie on any axis
(−3, −5), because the point satisfies one of the equations
(−3, −5), because the point lies between the two axes

Answers

The solution to the system of equations (−3, −5)

We have given that,

Two lines, A and B, are represented by the equations given below:

Line A: y = x − 6

Line B: y = 3x + 4

Line A

y = x - 2

Line B

y = 3x + 4

If we equate those 2 equations

x - 2 = 3x + 4

2x = -6

x = -3

y = -5

So the answer is

(−3, −5), because the point satisfies both equations.

Answers

By using triangle properties and the law of the sines twice, we find that the missing angle is 50° and the missing lengths are 14.232 and 16.229, respectively.

How to determine the missing variables of a triangle

In this triangle we know the length of a side (b = 13) and the measure of two adjacent angles (A = 57°, C = 73°). First, we determine the measure of the missing angle by using triangles properties:

B = 180° - 57° - 73°

B = 50°

Lastly, we determine the missing lengths by the law of the sines:

[tex]a = 13 \times \frac{\sin 57^{\circ}}{\sin 50^{\circ}}[/tex]

a ≈ 14.232

[tex]c = 13 \times \frac{\sin 73^{\circ}}{\sin 50^{\circ}}[/tex]

c ≈ 16.229

By using triangle properties and the law of the sines twice, we find that the missing angle is 50° and the missing lengths are 14.232 and 16.229, respectively.

Somebody help please

Answers

Answer:

Emily raised $37.50

Justin raised $57.50

Step-by-step explanation:

(Step 1)

Say "x" equals the amount of money Emily made and "y" equals the amount of money Justin made. You can set up an equation with both of these variables because we know that they made a combined $95.

x = Emily's earnings

y = Justin's earnings

Emily + Justin = 95

x + y = 95

(Step 2)

The fact that there are two variables makes it difficult to find how much each person made individually. However, we can eliminate the "y" variable when we remember that Justin made $20 more than Emily. Now, we can substitute "x + 20" in for "y".

x + 20 = y

x + y = 95

x + (x + 20) = 95

(Step 3)  

Finally, we can solve for the "x" variable.

x + (x + 20) = 95

2x + 20 = 95                                <------ Combine like terms

2x = 75                                         <------ Subtract 20 from both sides

x = 37.5                                        <------- Divide both sides by 2

(Step 4)

Since we know the value of "x", we can plug it into one of the equations to find the value of "y".

x + 20 = y

37.5 + 20 = y

y = 57.5

Answer:

Emily raised $37.5 and justin raised $57.5

Find the amount and compound interest on 1 (a) Rs. 16000 for 2+1/3 years at 15% per annum. 3​

Answers

The amount and compound interest are Rs22169.11 and Rs6169.11 respectively

Compound interest

The formula for calculating the compound interest is expressed as:

P(t) = P0(1+r)^t

Substitute the given parameters

P(7/3) = 16000(1+0.15)^7/3

P(7/3) = 16000(1.15)^7/3

P(7/3) = 22169.11

For the interest

Interest = 22169.11 - 16000

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]n_1 = n_2 = n_3 = n_4 = 3[/tex]

What number is 15% of 43
?
43 % of 300 is what
number?
12% of what number is 43?
43 is what percent of 106?
What percent of 43 is 6?

Answers

Step-by-step explanation:

So when a question asks what is x% of the y number. It's asking you to convert the x into decimal form by dividing by 100 and then multiply it by y. This gives you the equation: [tex]y * \frac{x}{100}[/tex] which gives you x% of y. so 15% of 43 is [tex]43 * \frac{15}{100} = 6.45[/tex]. 43% of 300 is [tex]300 * \frac{43}{100} = 129[/tex].

the 12% of what number is 43 is a bit more tricky. It's asking you to instead find a number in which 12% of it is equal to 43. So instead of plugging solving for the percentage (which is already given) you solve for y. This gives you the following equation: [tex]y * \frac{12}{100} = 43[/tex]. Now all you do is calculate 12/100 which gives you [tex]y * 0.12 = 43[/tex]. now divide both sides by 0.12 to solve for y. This gives you [tex]y = 358.\overline{33}[/tex]

43 is what percent of 106? This question is also a bit tricky, but instead of solving for y, you're solving for x. So plug in the known values, which gives you the equation: [tex]106 * \frac{x}{100} = 43[/tex]. Divide both sides by 106 to get [tex]\frac{x}{100} \approx 0.406[/tex] and now multiply both sides by 100. this gives you [tex]x \approx 40.57[/tex] which is the answer 40.57%

What percent of 43 is 6. This is asking the same thing just in a different way. So percentage = unknown, entire number = 43, entire number * percentage = 6. With these values we get the equation: [tex]43 * \frac{x}{100} = 6[/tex]. Divide both sides by 43 to get [tex]\frac{x}{100} \approx 0.140[/tex] now multiply by 100 to get [tex]x \approx 13.95[/tex] which is the answer 13.95%

A regular six-sided die is rolled 1000 times. Use the binomial distribution to determine the standard deviation for the number of times an odd number is rolled

Answers

The standard deviation for the number of times an odd number is rolled is 15.8

How to determine the standard deviation?

The given parameters are:

Die = regular six-sided die

p = 1/2 = 0.5

The standard deviation is then calculated as;

[tex]\sigma = \sqrt{np(1 - p)[/tex]
