find the value of x and a equals -2

The equation of the line is: y = 9.

To write the equation of a line in point-slope form, where (a, b) is a point on the line, and m is the slope, the equation can be expressed as:

y - b = m(x - a).

Given:

Two ponts on a line, (-4, 9) and (-1, 9)

Find the slope (m):

Slope of the line, m = change in y / change in x = (9 - 9)/(-4 -(-1))

Slope (m) = 0/-3 = 0

Substitute m = 0, and (a, b) = (-1, 9) into y - b = m(x - a):

y - 9 = 0(x - (-1))

y - 9 = 0(x + 1)

y - 9 = 0

y = 9

Given expression:

[tex]\frac{8^{\frac{1}{4} }*4^{\frac{1}{6} }}{2^{\frac{1}{6} }}[/tex]

Exponents

Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself. For example, 8 is multiplied by itself 3 times, i.e. 8 × 8 × 8. This can be written as [tex]8^3[/tex]. Here, 3 is the exponent and 8 is the base. This can be read as 8 is raised to power 3.

We know that,

8 is the cube of 2 and 4 is the square of 2, hence, we can write,

[tex]\frac{(2^3)^{\frac{1}{4} }*(2^2)^{\frac{1}{6} }}{2^{\frac{1}{6} }}[/tex]

Using the properties of exponents, we can write,

[tex]\frac{(2)^{\frac{3}{4} }*(2)^{\frac{2}{6} }}{2^{\frac{1}{6} }}[/tex]

Simplifying this further, we can write,

[tex]\frac{2^{(\frac{3}{4}*\frac{2}{6}) }}{2^{\frac{1}{6} }} = \frac{2^{\frac{1}{4} }}{2^{\frac{1}{6} }} = 2^{\frac{1}{4}-\frac{1}{6} }=2^{\frac{3-2}{12} }=2^{\frac{1}{12}}[/tex]

The most appropriate choice for mean, median and mode will be given by-

Value of m = 20

What is mean, median and mode?

Mean of a data set gives the average value of the data set

Mean is calculated by the dividing sum of all observations by the number of observations.

Median is the middle value of the data set when the data set is arranged in ascending or descending order

Mode is the value of the data set which has the highest frequency

Here,

Let the number of integers be n

mean = 22

Sum = 22 x n

       = 22n

Now m is replaced by m + 10

New sum = 22n + 10

New mean = 24

New sum = 24n

By the problem,

22n + 10 = 24n

24n - 22n = 10

2n = 10

n = [tex]\frac{10}{2}[/tex]

n = 5

Now mode of 5 numbers = 32

Smallest number = 10

Data set = {10, x, m, 32, 32}

Now , if m is replaced by m - 8, the new median is m - 4

Since 5 is odd, m - 4 is a member of this data set

So x = m-4 (As m- 8 < m - 4, so on replacing m by m-8 will shift m - 8 to second place and x to third place as the data set is arranged in ascending order)

Data set  = {10, m-4, m, 32, 32}

Mean = [tex]\frac{10+(m-4)+m+32+32}{5}[/tex]

[tex]22 = \frac{70 + 2m}{5}\\70 + 2m = 22 \times 5\\70 + 2m = 110\\2m = 110 - 70\\2m = 40\\m = \frac{40}{2}\\m = 20[/tex]

Answer: -6

Step-by-step explanation:

Given: y = 100 - 2x

New: y = 100 - 2(x + 3)

          = 100 - 2x - 6

          = 94 - 2x

The original equation had a y-intercept of 100.  The new equation has a y-intercept of 94.  The y-value changes by -6 units.

Answer:

-3

Step-by-step explanation:

To make the equation have infinitely many solutions, we need to make both sides equal.

i will use variable y in place of blank

-x + 20 + yx = -4x + 20

-x + yx = -4x

yx = -3x

y = -3

now we can check the answer

-x + 20 - 3x = -4x + 20

-4x + 20 = -4x + 20

0 = 0

this means there are infinitely many solutions

If Lamont withdraws $2,750 monthly, he will be 66 years old (after 134.326 months) when the money runs out.

We can calculate the number of monthly withdrawals using an online finance calculator.

It determines the number of periods it will take for the investment to be exhausted, given an interest rate of 3.8%.

I/Y (Interest per year) = 3.8%

PV (Present Value) = $300,500

PMT (Periodic Payment) = $-2750

FV (Future Value) = $0

Results:

N = 134.326 months

Years = 11 years (134.326/12)

Age at FV = $0 is 66 years (55 + 11)

Sum of all periodic payments = $-369,397.09 (134.326 x $-2,750)

Total Interest = $68,897.09

Thus, making a monthly withdrawal of $2,750 will exhaust the investment when Lamont turns 66.

Answer:

Step-by-step explanation:

To find the lowest price per ounce, we must find the unit rate (how much does it cost to buy 1 unit of something).

The way to do this is divide the price by the quantity.

Option 1) [tex]\frac{1.65}{26/5} = 1.65 * 5/26 = 8.25/26 = 33/104[/tex]

For the first option, every ounce costs $33/104.

Option 2) [tex]\frac{10.4}{26} = 0.4 = \frac{4}{10}[/tex]

For the second option, every ounce costs $4/10.

Since we know that 33/104 is less than 4/10, option 1 is more worth it as every ounce costs less than option 2.

Ok, so

First of all, remember that a line can be described by two forms:

1. y = mx+b, where m is the slope and b is the y - intercept-

2. We would have the general equation for a line, which is:

Ax + By + C = 0

Where m(slope) is -A/B and the intercept (b) is -C/B.

Now, let's find the slope and y - intercept for each line here below.

a. y = 5 - 6x

Here we have a line which has the first form (1). So, if we rewrite:

y = - 6x + 5.

So, If we compare with the first equation, we notice that m = -6 and b = 5

or, m = -6 and b = (0,5)

b. y = (5/6)x + 1

Here we have a line which has the first form (1).

So, if we compare, we notice that m = 5/6 and b = 1, or, m = 5/6 and b = (0,1)

c. 5x - 6y = 6

If we rewrite the equation:

5x - 6y - 6 = 0

Here we have a line which has the second form (2).

We know that

A = 5

B = -6

C = -6

If we replace, m = -A/B, which is -(5) / (-6) , and this is 5/6.

And, y intercept will occurs at y = -C/B, which is -(-6) / -6, which is 6/-6, or -1.

So, the slope will be 5/6 and y-intercept (0,-1).

m = 5/6 and b = (0,-1)

d. 5x + 6y = 6

If we rewrite the equation:

5x + 6y - 6 = 0

Here we have a line which has the second form (2).

We know that:

A = 5

B = 6

C = -6

If we replace, m = -A/B, which is -(5) / 6, so, m = -5/6

And, y intercept will occurs at y = -C/B, which is -(-6) / 6, so, b = 1

Finally, m = -5/6, and b = (0,1)

At x=1 in the domain f(x)=0.

The entire range of independent variable values is the domain of a function.

This definition can be stated simply as follows: The domain is the collection of all x-values that can be used to make the function "work" and produce actual y-values.

Keep in mind that a fraction's denominator (bottom) cannot be zero when determining the domain.

A square root must have a positive number under it.

At the points where the function's graph and the x-axis connect, f(x)=0.

You can see from the diagram that the function's graph crosses the x-axis three times:

1)between -3 and -2

2)between -1 and 0;

3)at x=1.

Since x=1 is the value of x from the domain, then correct choice is option C.

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

Consider the relation {(0,7),(0,8),(1,7),(1,8),(1,9),(2,10)} . Here, the relation is given as a set of ordered pairs. The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} .

The range of values of T is the domain is,

T = ( 0 , 60 )

The range of values of W is the domain is,

W = ( 0 , 35T+700 )

0 ≤ 35T+700

We have to blend two brands of dressing with different proportions of vinegar. We want to obtain a mix of 230 cubic milimiters with a proportion of 11% of vinegar.

We can call A to the amount of dressing with 8% vinegar and B the amount of dressing with 13% vinegar.

Then, if the volume of the mix is 230 mm³, we can write:

We can obtain another equation by looking at the amount of vinegar in the mix.

The amount will be the volume of the mix (230 mm³) times the proportion of vinegar (11% or 0.11 in decimal).

This amount of vinegar will be contributed by the vinegar of each brand. The first brand will contribute with a volume of A times 0.08 and the second brand will contribute with B times 0.13.
