Given:

m = 10

The line passes through the point (6,2).

To find:

The equation of line in the standard form.

Solution:

If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of line is

[tex]y-y_1=m(x-x_1)[/tex]

The line passes through the point (6,2) and m = 10. So, the equation of line is

[tex]y-2=10(x-6)[/tex]

[tex]y-2=10x-60[/tex]

[tex]y-10x=-60+2[/tex]

[tex]-10x+y=-58[/tex]

Therefore, the correct option is A.

Answer:

$68.20

Step-by-step explanation:

Answer:

85$

Step-by-step explanation:

p = original price

68 = p - 20%p

68 = p - 0.20p

68 = 0.80p

85 = p

The original price was $85.

The original price is 100%. The sales price was 20% off - subtract. So the sale price was 100% - 20% = 80%.

Incase you wanna know how I came up with the 0.80p :)

I tried, but I'm not a math whiz or anything.

The amount of interest is $1170.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].

Given that, principal =$6500, rate of interest =4.25% and time period = 4 years.

Here, Amount = 6500(1+4.25/100)⁴

= 6500(1+0.0425)⁴

= 6500(1.0425)⁴

= 6500×1.18

= $7670

Interest = Amount-Principal

= 7670-6500

= $1170

Therefore, the amount of interest is $1170.

3 1/2 quarts of blue

5 quarts of white

3 1/2 α 5

7/2 = 5k

Where k is the proportionality constant

k = 7/2 ÷ 5

k = 7/2 * 1/5

b = kw

b = 0.7w

Answer:

only C is non-linear

Step-by-step explanation:

A linear equation is of the form;

y = mx + c

we have single powers of x and y; also, there is no product of x and y

Thus, we have;

a; 12x + 3y = 7

y =( -12x + 7)/3

this shows we have a linear equation

b. y + x = 4x + 5

y = 4x-x + 5

y = 3x + 5

This is a linear equation

c. y = 8/x^2

This is non-linear; we already have one power of x as 2

Answer:

mode: none

median: 4

mean: 4.2

Step-by-step explanation:

when dealing with mean, median, mode the first thing you should do is arrange the numbers in order from least to greatest. Once you have done so the easiest thing to do first is see which number is in the very middle, this is your median. Mode is the number that appears the most. Mean is another word for average. To find the mean, add up all the numbers then divide the sum of all the numbers by how many numbers are listed. In this case, 2+3+4+5+7=21.

21 divided by 5 (how many numbers there are) = 4.2

Answer: Smaller number = 6

Larger number = 20

Step-by-step explanation:

Let the smaller number be x.

Let the larger number be y.

Three times a larger number is 30 more than 5 times a smaller number. This will be:

3 × y = (5 × x) + 30

3y = 5x + 30 ...... i

The sum of the larger number and 5 times the smaller number is 50. This will be:

y + 5x = 50 ...... ii

From equation ii

y + 5x = 50.

y = 50 - 5x ...... iii

Put the value of y = 50 - 5x into equation i

3y = 5x + 30

3(50 - 5x) = 5x + 30

150 - 15x = 5x + 30

150 - 30 = 5x + 15x

120 = 20x

x = 120/20

x = 6

The smaller number is 6

Note that y + 5x = 50

y + 5(6) = 50

y + 30 = 50

y = 50 - 30

y = 20

The bigger number is 20

Answer:

y = x + 1

Step-by-step explanation:

The line y = x  goes through the origin, and forms a perfect 45 degree angle with the x axis.

This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.

Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so

y = 1x + 1 = x + 1

y = x + 1

What is the system of equations?

A system of equations is a collection of one or more equations that are considered together. The system can consist of linear or nonlinear equations and may have one or more variables. The solution to a system of equations is the set of values that satisfy all of the equations in the system simultaneously.

Let's use the given information to set up a system of equations to solve for Ryan's age.

We know that Ryan's age, y, is twice Chaise's age, x, so we can write:

y = 2x (Equation 1)

We also know that Ryan is 11 years older than Chaise, so we can write:

y = x + 11 (Equation 2)

Now we can substitute Equation 1 into Equation 2:

2x = x + 11

Simplifying, we get:

x = 11

So Chaise is 11 years old.

To find Ryan's age, we can use either Equation 1 or Equation 2. Let's use Equation 2:

y = x + 11

y = 11 + 11

y = 22

Therefore, Ryan is 22 years old.

Since the dice is fair, each number (1 through 6) has an equal probability of appearing on each roll. The probability of rolling a six on any one roll is 1/6. Hence, 1/6 times of 480 is 80 times.

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to occur.

To find the expected number of times Caroline would roll a six, we can use the formula:

Expected number of occurrences = Probability of occurrence x Number of trials

In this case, the probability of rolling a six is 1/6, and the number of trials is 480. Therefore, the expected number of times Caroline would roll a six is:

Expected number of times = (1/6) x 480 = 80

Therefore, Caroline would expect to roll a six 80 times out of 480 rolls.
