Answer:

x=-15/2 and y=7

Step-by-step explanation:

y=-4x-23

y=-2x-8

Two methods, substitution and elimination. Elimination is the easiest, so you can subtract the equations.

y=-4x-23

-(y=-2x-8)

----------------------

y=-4x-23

-y=2x+8

------------ so solve :)

0=-2x-15

becomes 2x=-15

so x=-15/2

------------------------ plug in x to solve for y

and you get y=7

Answer:

[tex]A=172.04\ in^2[/tex]

Step-by-step explanation:

Given that,

The side length of a regular pentagon = 10 inches

The distance from the center to a vertex of 10 inches

The formula for the area of a regular pentagon is given by :

[tex]A=\dfrac{1}{4}\sqrt{5(5+2\sqrt{5} } }\ a^2[/tex]

Put a = 10

So,

[tex]A=\dfrac{1}{4}\times \sqrt{5(5+2\sqrt{5} )} \times 10^2\\\\A=172.04\ in^2[/tex]

So, the area of a regular pentagon is equal to [tex]172.04\ in^2[/tex].

Answer:

The median value is better because it is not affected by the skewness of the data

Step-by-step explanation:

The median is  better in representing the data of a stem and leaf plot because the median value is not affected so much by outliers and skewness of the data. for example:  for a downward skewed stem and leaf plot the value of the median is greater than the mean value

Hence the median value is a better representation of the central tendency

Step-by-step explanation:

They are both Right triangles (a given set of triangles are congruent if the corresponding lengths of their hypotenuse and one leg are equal.)

Answer:a)m =K n

b)m = 32

c)n=15

Step-by-step explanation:

M varies directly as n can be expressed mathematically as

m ∝ n

Introducing the constant of proportionality, K, we have that

m =K n

Now when m=14 and n=7, K becomes

14=K X 7

K=14/7 = 2

b) find m when n=16

m =K n

m = 2 x 16=32

c) find n when m=30

m =K n

30=2 x n

n=30/2 =15

Expression is formed using numbers, variables, and mathematical operations. The value of m, when the value of n is 16 is 32.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As we know that the value of m is directly varying with n, therefore, we can write the relationship as,

[tex]m \propto n[/tex]

Now, in order to remove the proportionality, we will add a constant,

[tex]m = kn[/tex]

As the value of m and n is given as 14 and 7, substitute the values in order to get the value of the constant k,

[tex]m = kn\\14 = k(7)\\\dfrac{14}{7} = k\\k=2[/tex]

We know the value of the constant k is 2, therefore, the equation can be written as,

[tex]m=2n[/tex]

Substitute the value of n as 16, to get the value of m,

[tex]m=2n\\m=2(16)\\m=32[/tex]

Hence, the value of m, when the value of n is 16 is 32.

The true statements are C and D.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Probability = Number of desired outcomes / Total number of outcomes.

Total number of outcomes = 6 × 3 = 18

A) Number of times rolling a 3 on the number cube and the spinner landing on blue = 1

Corresponding probability = 1/18

B) Probability of Jamie rolling a 2 or 3 on the number cube and the spinner landing on green = 2/18 = 1/9

C) Probability of Jamie rolling an even number on the number cube and the spinner landing on blue = 3/18 = 1/6

D) Probability of Jamie rolling a 1 on the number cube and the spinner landing on blue or green = 2/18 = 1/9

E) Probability of Jamie rolling a 5 on the number cube and the spinner landing on red = 1/18

Hence the true statements are C and D.
