Which is not an equation of the line going through (6, 7) and (2,-1)?
A.y+1=2(x-2)
OB. y-7-2(x-6)
OC. y-1-2(x+2)
D. y=2x-5

Reason:

Subtract 3x from both sides. They cancel out and go away. The x term is fully eliminated and we're left with the equation 8 = 9, which is a false statement. Therefore, the original equation is always false regardless of what you pick for x. This is why there aren't any solutions.

Visually you can graph y = 3x+8 and y = 3x+9. You'll get parallel lines that never intersect. We need the lines to intersect if we wanted a solution point. Parallel lines have the same slope, but different y intercepts.

Because the system has no solutions, we consider the system inconsistent.

Multiply that by 2 then you get 18.

Half of 10% will give you the remaining 5% which is 4.5

Then add 18 and 4.5 you 22.5

The distance between two points A (-10, -7) and B(-8,1) will be equal to 8.2 units.

What do you mean by the distance between points ?

Distance between two points is the length of the line segment that connects the two locations in a plane.

It is given that the distance between points A (-10, -7) and B(-8,1) is to be calculated.

We can find out the distance by using the distance formula which is given by :

AB = [tex]\sqrt({x_{2} - x_{1})^2 + (y_{2}- y_{1})^2}[/tex]

AB = √ [( -8 -(-10)]^2 + [ 1 - (-7)]^2}

AB = √ (2² + 8²)

AB = √68

AB = 8.24 units

If we round off it to the nearest tenth then , hundredth place is less than 5 that meant 2 will be at the tenths place.

or

AB = 8.2 units.

Therefore , the distance between two points A (-10, -7) and B(-8,1) will be equal to 8.2 units.

The raw score x, corresponding to z = 2 is calculated as; 90

We are given;

Population Mean; μ = 78

Sample mean; x' = ?

Population standard deviation; σ = 6

Solving a system of equations we can see that the two numbers are 727 and 4

Let's define x as the 3-digit number and y as the one-digit number.

Then we know that the sum is equal to 731:

x + y = 731

And the product is equal to 2,908, then:

x*y = 2,908

So we have a system of equations:

x + y = 731

x*y = 2,908

Isolating x on the first equation gives:

x = 731 - y

Now we can replace that in the other equation to get:

(731 - y)*y = 2,908

Now we can solve this quadratic equation to find the value of y.

731*y - y^2 = 2,908

-y^2 + 731*y - 2,908 = 0

The solutions are:

y = (-731 ± √( 731^2 - 4*(-2,908)*(-1))/(-2)

y = (-731 ± 723)/-2

Now, y is an one digit number, then:

y = (-731 + 723)/-2 = 4

And x will be the 3 digit number:

x = 731 - x = 731 - 4 = 727

So the two numbers are 727 and 4

The amount that would be in th IRA when he retires at age 65 is $21,932.15.

An annuity is a series of payment that is made over a period of time. In this question, the annuity is monthly which lasts for 47 years (65 - 18). An ordinary annuity is when the payments are made at the end of the period. An annuity due is when the payment is made at the beginning of the period.

The amount deposited increases by the amount you put in it every month and by the interest rate the account accrues. The account earns an APR, this means that interest would be compounded yearly.  

Total amount of deposits = amount deposited monthly x number of months in a year x number of years

$60 x 12 x 47 = 33,840

The formula that can be used to determine the future value of the account in 47 years is:

Monthly deposit x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

$60 x [{(1.00583)^564 - 1} / 0.07] = $21,932.15

The words related to the mathematical operation of division are:

A division between two numbers tells us how many times the denominator can be fit into the numerator (the numerator is the number being divided by the denominator).

The "math word" used for divisions is "quotient"

The quotient between two numbers is equivalent to say the "outcome of the division between two numbers"

So that is one of the correct options.

Other correct option is "separate"

Like in the word problem example "3 friends separate evenly 9 candy between them". Here we have a division.

Similar, "cut" is also related to divisions.

The three solutions to the linear equation are (0, -2), (1, 1) and (2, 4)

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The linear equation is given as

g(x) = 3x - 2

To determine the solution to the linear equation, we set the value of x to some values

say x = 0, 1 and 2

Substitute x = 0, 1 and 2 in g(x) = 3x - 2

g(0) = 3(0) - 2 = -2

g(1) = 3(1) - 2 = 1

g(2) = 3(2) - 2 = 4

Hence, the three solutions to the linear equation are (0, -2), (1, 1) and (2, 4)

The given parameter is the graph of the beam

From the graph, we can see that the beam does not shine on all parts of the wall.

It shines on some part and doesn't on other parts

This means that the function is undefined

Hence, the interpretation of the beam on the wall is that when the function is undefined, the light is not shining completely on the wall

To do this, we use the following computations:

[d(0.1) - d(0)]/[0.1 - 0] = [5.5236 - 0]/[0.1 - 0] = 55.236

[d(0.2) - d(0.1)]/[0.2 - 0.1] = [12.3512 - 5.5236]/[0.2 - 0.1] = 68.276

[d(0.3) - d(0.2)]/[0.3 - 0.2] = [23.3985 - 12.3512]/[0.3 - 0.2] = 110.473

[d(0.4) - d(0.3)]/[0.4 - 0.3] = [52.3206 - 23.3985]/[0.4 - 0.3] = 289.221

Antonio will save $113.4 after calculating using mensuration and buying from Pets Galore instead of Healthy pets.

As per the question statement, Antonio needs to buy 150 pounds of dog food for the local dog shelter. Healthy Pets, sells dog food in 50-pound bags for $85.95 per bag and Pets Galore sells one bag for $48.15

We are supposed to calculate the amount of money saved by Antonio if he buys 150 pounds of dog food from Pets Galore instead of from Healthy Pets.

Using concept of mensuration,

Quantity of dog food in one bag = 50 pounds

Quantity required of dog food = 150 pounds

Therefore number of bags required = 150/50 = 3

Price of dog food at Pets Galore per bag = $48.15

Total money to be paid to Pets Galore for 3 bags = $48.15*3  = $144.45

Total money to be paid to Healthy Pets for 3 bags = $85.95*3 = $275.85

Therefore money saved = $275.85 - $144.45  = $113.4
