Answer:

y = [tex]\frac{5}{6}[/tex] x + [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (4, 6)

m = [tex]\frac{6-1}{4+2}[/tex] = [tex]\frac{5}{6}[/tex] , thus

y = [tex]\frac{5}{6}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 6 ), then

6 = [tex]\frac{20}{6}[/tex] + c ⇒ c = 6 - [tex]\frac{20}{6}[/tex] = [tex]\frac{16}{6}[/tex] = [tex]\frac{8}{3}[/tex]

y = [tex]\frac{5}{6}[/tex] x + [tex]\frac{8}{3}[/tex] ← equation of line

Answer:

13

Step-by-step explanation:

The mean of all the numbers is the sum of the numbers divided by the number of numbers.

The sum of all of the numbers is 10 + 14 + 16 + 12 + 14 + 14 + 11 = 91.

We then divide by 7, getting 13.

Answer:

13

Step-by-step explanation:

The mean of a data set is the average value of the set.  

To find the average, we simply need to add all the values and then divide by the number of values.

There are 7 values. So, add all of them and then divide by 7.

[tex]\bar x=\frac{10+14+16+12+14+14+11}{7}[/tex]

Add:

[tex]\bar x=\frac{91}{7}[/tex]

Divide:

[tex]\bar x=13[/tex]

Therefore, our average is 13.  

(Note that the x with the bar on the top is a common way to denote the mean.)

Answer:            535

                         0.20x+350

Step-by-step explanation:

If Grayson makes $925 in sales he receives $535 and if he makes x sales then he receives $350 +0.2x

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here he makes a base income of $350 and he also earns 20% of his sales output and thus if he makes $925, his total income is

= 350+0.2×925

=$535

And let Grayson make x sales in one week then his salary will be

= 350+0.2x

Hence, If Grayson makes $925 in sales he receives $535 and if he makes x sales then he receives $350 +0.2x

Step-by-step explanation:

Answer:

-1/12x

Step-by-step explanation:

Let total people at the picnic=x

People who chose apple= 1/3x

People who chose orange= 3/4x

People who chose each of the fruit= People who chose apple + People who chose orange

=1/3x + 3/4x

= 4x+9x / 12

=13/12x

People who chose each of the fruit= 13/12x

what fraction of the people chose both of them?

Fraction of the people who chose both fruits= Total people at the picnic - People who chose each of the fruit

=x - 13/12x

=12x- 13x /12

= -1/12 x

Answer:

The total number of games =25 which is 10+15

then the number of wins are 10.

which is 10/25.

A ratio shows us the number of times a number contains another number. The ratio of wins to the total number of games is 2/5.

A ratio expresses the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.

Given that a basketball team won 10 games and lost 15. Therefore, the total number of games that the team plays is,

Total number of games = games won + games lost

                                       = 10 + 15

                                       = 25

Now, the ratio of wins to the total number of games can be written as,

Ratio = Games Won/ Total number of games

         = 10/25

         = 2/5

Hence, the ratio of wins to the total number of games is 2/5.

Perpendicular.

x = -1 is a vertical line intersecting the x-axis at (-1, 0).

y = -1 is a horizontal line intersecting the y-axis at (0, -1).

Because these lines are both straight, they will eventually intersect at (-1, -1). They will also form 90° angles, the definition of perpendicular.

20.A) x+y=3^2

Step-by-step explanation:

22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is intersection, option A is correct.

21.  [tex]x+y=3^2[/tex]  is not a function. Option A is correct.

22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is an example of a compound inequality involving "and."

Both inequalities need to be satisfied simultaneously for the compound inequality to be true.

Hence, the  compound inequality is intersection.

21.  A function is a relationship between two variables in which each input value (x) corresponds to exactly one output value (y).

In this case, the equation [tex]x+y=3^2[/tex] does not represent a clear relationship between x and y.

[tex]x+y=3^2[/tex] represents a curve in the xy-plane rather than a function.

Hence,  [tex]x+y=3^2[/tex]  is not a function.
