Can I get help with what y equals?

Answer:

(4,8) is the answer.

Step-by-step explanation:

To solve by substitution, you need to isolate a variable. The bottom equation already has y isolated, so we can just plug that into the other equation:

[tex]2x=-2x+16[/tex]

Add [tex]2x[/tex] to both sides in order to get rid of the [tex]-2x[/tex] on the right side:

[tex]4x=16[/tex]

Now divide by 4 on both sides to get:

[tex]x=4[/tex]

That gives us our x. Now plug in that x into either equation. I will just choose the bottom equation:

[tex]y=2(4)\\y=8[/tex]

Therefore the solution to this problem is (4,8).

Answer:

x=2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

2x = 5x-6

Subtract 5x from each side

2x-5x = 5x-6-5x

-3x = -6

Divide by -3

-3x/-3 = -6/-3

x = 2

Answer:

x = 6

Step-by-step explanation:

Vertical angles in a geometry are equal. Hence m<A = m<B

Given that

m<A =  3x - 9

m<B - x+3

Then 3x - 9 = x+3

3x - x = 3 + 9

2x = 12

Divide both sides by 2

2x/12 = 12/2

x = 6

Hence the value of x is 6

Answer:

The answer is 5.9

Step-by-step explanation:

1) Subtract 31.7 from both sides.

[tex]14 - 31.7 = - 3x[/tex]

2) Simplify 14 - 31.7 to -17.7

[tex] - 17.7 = - 3x[/tex]

3) Divide both sides by -3.

[tex] \frac{ - 17.7}{ - 3} = x[/tex]

4) Simplify -17.7/-3 to 5.9

[tex]5.9 = x[/tex]

5) Switch sides.

[tex]x = 5.9[/tex]

Therefor, the answer is x = 5.9.

Step-by-step explanation:

Answer:

a)The P-value will be too small

b) He will reject the Null hypothesis

Step-by-step explanation:

a) If David incorrectly uses the z-distribution instead of the t-distribution, he will obtain a p-value that is too small   because p-values obtained using Z distribution are smaller when compared to p-values obtained using t-distribution

b) He will reject the Null hypothesis given that the P value he will obtain will be very different from the one he obtained using z-distribution

The required distance of  Leek from Reidville directly is 186.82 miles.

Given that,
An airplane is flying from Reidville to Leek. The airplane flies 50 miles East and then 180 miles south. How far is Leek from Reidville directly is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
The direct distance can be given as,
x = √[50² + 180²]
x = √34900
x = 186.82

Thus, the required distance of  Leek from Reidville directly is 186.82 miles.

Answer:

Individual error rate = 0.01

Therefore, Option b) 0.01 is the correct answer

Step-by-step explanation:

Given the data in the question;

family wise error rate ∝ = 0.05

there are ten levels of one factor but

important comparisons m = 5

the individual error rate need to be for each of those 5 comparisons = ?

we know that;

individual error rate = family wise error rate ∝ / important comparisons m

so we substitute

individual error rate = 0.05 / 5

individual error rate = 0.01

Therefore, Option b) 0.01 is the correct answer

Answer:

A^2 + B^2 = C^2

Answer:

f(x) is another way to write y.

You have y = 6x - 8.

To find the inverse, switch the x and the y and solve for the new y.

Switching gives you x = 6y - 8.

You add 8 to both sides to give you 6y = x + 8.

Divide both sides by 6 gives you the inverse as y =1/6x + 4/3

[tex]Fraction = \frac{3}{5}[/tex]

Step-by-step explanation:

Given

[tex]Fraction = \frac{12}{20}[/tex]

Required

Rename using division

This simply means that we reduce the fraction

So, we have:

[tex]Fraction = \frac{12}{20}[/tex]

Divide by 4/4

[tex]Fraction = \frac{12/4}{20/4}[/tex]

[tex]Fraction = \frac{3}{5}[/tex]

Answer:

[tex]\frac{28}{3}=t[/tex]

Step-by-step explanation:

[tex]\frac{4}{3}=\frac{t}{7}[/tex]

Use cross products to simplify the equation. Multiply the denominator of the second fraction by the numerator of the first fraction, and the denominator of the first fraction by the numerator of the second,

[tex](4)(7) = (3)(t)[/tex]

Simplify,

[tex]28=3t[/tex]

Inverse operations,

[tex]\frac{28}{3}=t[/tex]

Answer:

1 cheese is left over.

Step-by-step explanation:

Given that,

1219 kg of Swiss cheese is packaged in 3 kg bags.

i.e. 3 kg bags = 1219 kg of Swiss cheese

Implies, 1 kg bag = [tex]\dfrac{1219}{3}[/tex] kg of swiss cheese

If we divide 1219 by 3, we get [tex]46\dfrac{1}{3}[/tex]. Here, 46 is the quotient and  1 is the remainder.

It means 1 cheese is left over.

Step-by-step explanation:

The sample proportion of cell phone users who develop cancer of the brain or nervous system = [tex]\dfrac{133}{420027}=0.0003166[/tex]

Sample size : 420027

Confidence interval for p: [tex]\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex], where [tex]\hat{p}[/tex]= sample proportion , n= sample size , z* = crirical z value.
