Which of these strategies would eliminate a variable in the system of equations?2x−5y=13
−3x+2y=13
A. Multiply the top equation by 2, multiply the bottom equation by 3, then add the equations.
B. Subtract the bottom equation from the top equation
C. Multiply the top equation by 3, multiply the bottom equation by 2, then add the equations.

Answers

Answer:

We conclude that when we multiply the top equation by 3, multiply the bottom equation by 2, then add the equations, it would eliminate the variable 'x'.

Thus, option (C) is true.

Step-by-step explanation:

Given the system of the equation

2x−5y=13

−3x+2y=13

Multiply the top equation by 3

3(2x−5y) = 3(13)

6x - 15y = 39

Multiply the bottom equation by 2

2(−3x+2y) = 2(13)

-6x + 4y = 26

Adding both equations

6x - 15y = 39

+

-6x + 4y = 26

___________

0x - 11y = 65

-11y = 65               ∵ x variable eliminates

Divide both sides by -11

y = -65/11

Therefore, we conclude that when we multiply the top equation by 3, multiply the bottom equation by 2, then add the equations, it would eliminate the variable 'x'.

Thus, option (C) is true.

Answers

Answer:

a) 6.1 feet

b) 12.6 feet

Step-by-step explanation:

Using trigonometric ratios we know that:

[tex]sin = \frac{opp}{hyp}\\cos = \frac{adj}{hyp}\\tan = \frac {opp}{adj}[/tex]

AKA SohCahToa.

To find the height, we will use sine.

[tex]sin(26^o)= \frac{x}{14}\\14*sin(26^o)=\frac{x}{14}*14\\14sin(26^o)=x\\x=6.14[/tex]

To find the length we will use cosine.

[tex]cos(26^o) = \frac{x}{14}\\14*cos(26^o)=\frac{x}{14}*14\\14cos(26^o)=x\\x=12.6[/tex]

A real-estate company appraised the market value of 36 homes in Lyttelton and found that the sample mean and standard deviation were $150,000 and $17,000 respectively. The real-estate company also appraised the market value of 45 homes in Aranui and found that the sample mean and standard deviation were $100,000 and $12,000 respectively. Calculate the 90% confidence interval estimate for the population difference in market value between the Lyttelton and Aranui areas .

Answers

Solution :

                    Sample size       Sample mean             Sample S.D.

Sample 1        [tex]$n_1=36$[/tex]              [tex]$\bar{x}_1=150,000$[/tex]               [tex]$s_1=17,000$[/tex]

Therefore, significance level, α = 0.1

Critical value, t* = 1.6706

So, the margin of error, [tex]$t^*=\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$[/tex]

Upper limit,  [tex]$(\bar x_1-\bar x_2)+\text{(margin of error)}=55597.9896$[/tex]

Therefore 90% C.I. is (44402.0104, 55597.9896)   or [tex]$44402.0104 < \mu_1 - \mu_2 < 55597.9896$[/tex]

According to a recent survey, 81 percent of adults in a certain state have graduated from high school. If 15 adults from the state are selected at random, what is the probability that 5 of them have not graduated from high school?

Answers

Answer:

0.090401

Step-by-step explanation:

Given that:

Probability of graduate = 81% = 0.81

P( not graduate) = p = (1 - 0.81) = 0.19

1 - p = 0.81

Using binomial distribution :

P(x = x) = nCx * p^x * 1-p^(n-x)

n = 15 ; x =5

P(x = 5) = 15C5 * 0.19^5 * 0.81^(15 - 5)

P(x = 5) = 15C5 * 0.19^5 * 0.81^10

P(x = 5) = 3003 * 0.0002476099 * 0.12157665459056928801

P(x = 5) = 0.090401

Answers

So if everyone voted there would be only 15 ppl in the class. So 15= 100%
Now put that on the bottom for your fractions 3/15 8/15 4/15 because you need to find the percentage of the whole 7th grade.
Now to get each% divide the top number by the bottom.
3/15=.2
8/15=.53
4/15=.25
Then times each decimal by 100 to get the decimal converted to percentage.
So 53% voted for comedy.

  y = 3

3x +2y = 6

  3·2 +2y = 6

  2y = 6 -6 = 0

2x +y = 6

The division of expression will give -

f(x) = x² + 1 + 4/(x + 2)

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is the expression as -

f(x) = (x³ + 2x² + x + 6)/(x + 2)

The given expression is -

f(x) = (x³ + 2x²)/(x + 2) + (x + 6)/(x + 2)

f(x) = x²(x + 2)/(x + 2) + (x + 6)/(x + 2)

f(x) = x² + (x + 6)/(x + 2)

f(x) = x² + (x + 2)/(x + 2) + 4/(x + 2)

f(x) = x² + 1 + 4/(x + 2)

Therefore, the division of expression will give -

f(x) = x² + 1 + 4/(x + 2)

Answer:

y=4x+3

Step-by-step explanation:

The slope is positive 4 and the y intercept is 3

Answer:

y = 4x + 3

Step-by-step explanation:

y = mx + b

m is the slope and b is the y-intercept

The slope is how much units it goes up/down while how much units it goes left/right from one point to the other. So two points we'll use for reference is (-1, -1) and (0, 3). You want to make sure the points u choose are whole numbers cause they're easier to tell. So the distance between those 2 points if it goes to the right once and goes up 4 units. Left/right is x and up/down is y, y/x is how u write the slope. So it's 4/1 which is just 4

The y-intercept is just where the line intercepts on the y-axis. The line goes through the point 3 on the y-axis, so it's 3

Input the numbers in the equation and it's y = 4x + 3
