What does 11x in the expression represent?

Answer:

The eqaution y + 1 = -2 (x-1) in slope intercept form is

y = -2x - 3

Step-by-step explanation:

Write in slope-intercept form, y = mx + b

Answer:

Option (4)

Step-by-step explanation:

If we draw a graph against x(Number of months) and y(Number of stamps),

We will get a straight line.

Let the equation of straight line be,

y = mx + b

Here, m = Stamps purchased per month

b = Jasmine was given stamps initially

From the table attached,

m = [tex]\frac{70-65}{2-1}[/tex] = 5 stamps per month

Therefore, equation of the line will be,

y = 5x + b

Since, a point (1, 65) lies on this line,

65 = 5(1) + b

b = 60

That means she was given 60 stamps initially.

Option (4) will be the answer.

Answer: Yes these triangles are similar

Step-by-step explanation:

First lets write down what we know just to make life easier

x=9

TL should be similar to CH

LY should be similar to KH

The angles should be equal due to SAS

So the first thing we know is true is the fact that they have equal angles. Now we have to find out if the sides are similar or if they change by the same ratio to the other. If TL is similar to CH and TL=25  and CH=10 what is the change in size or dilation. Division should do the trick so 25/10=2.5 so TY is greater than CH by a factor of 10. Which means that LY should also be greater than KH by a factor of 2.5. If we are told that x=9 than side LY or 4(9)-1=35 and KH 9+5=14

So side KH is 14 and LY is 35. Now to check if they are similar then KH should be greater by a factor of 2.5. If this is not true than the sides are not similar.  35/2.5=14

Since 35 divided by 2.5 is 14 we can tell both sides TL and LY are greater than KH and CH by a factor of 2.5

Hope this helps.

Answer:

1. All real numbers

Step-by-step explanation:

Simplifies to f(x) = 6x - 63, it will cross all x and y values.

The domain and range of the given function are all real numbers

We have given that,

f(x)=3(x−15)2+27​

f(x)=(3x-45)2+27

f(x)=6x-90+27

The domain is the set of points at which the function is defined.

The range of a set of data is the difference between the largest and smallest values. The difference here is specific, the range of a set of data is the result of subtracting the sample maximum and minimum.

To f(x) = 6x - 63, it will cross all x and y values.

Answer:

Number of green soccer balls = 7

Step-by-step explanation:

Total number of soccer balls = 30

Number of white balls = 9

Number of soccer balls excluding number of white balls = 30 - 9 = 21

Also, the remaining soccer balls are one of three different colors (blue, pink, or green) such that there is an equal number of blue, pink, and green balls.

Number of blue balls = Number of pink balls = Number of green balls = [tex]\frac{21}{3}=7[/tex]

Therefore,

Number of green soccer balls = 7

If two triangles are similar it means that all corresponding angle pairs are congruent and all corresponding sides are proportional. However, in order to be sure that two triangles are similar, you do not necessarily need to have information about all sides and all angles.

The probability that an adult who likes soccer ages 18-30 is approximately 0.444.

Given that the table is,

                                                         Age range

                                        18-30         31-50         51+             Total

                 Football            15              19             17                  51

Sport         Baseball            7               12             18                  37

                 Basketball         15              8              11                   34

                 Soccer               12              9               6                  27

Given:

Liked sport: Soccer

Age range: 18-30

To find the probability that an adult is aged 18-30 given that they like soccer, denoted as P(18-30 | S).

To calculate this probability, use the formula for conditional probability:

[tex]P(18-30 | S)= \frac{P((18-30) \cap (S))} {P(S)}[/tex]

P(18-30 ∩ Soccer) represents the probability that an adult is both aged 18-30 and likes soccer.

Looking at the provided table, the number of adults who like soccer and are aged 18-30 is 12.

P(Soccer) represents the probability that an adult likes soccer. The total number of adults who like soccer, regardless of age, is 27.

Now, calculate the probability:

P(18 - 30| S) = 12 / 27

≈ 0.444 (rounded to three decimal places)
