y=-4x-23
y=-2x-8
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

Why is the median better to represent the data of a stem and leaf plot? I NEED THE ANSWER NOW PLSSSS
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

The true statements are C and D.
What is Probability?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.

The resale value of a bike decreases by 14% per year. A new bike is valued at $350. Approximate the resale value after 4 years to the nearest dollar.
Answer: $191.45
Step-by-step explanation:
This question requires the price of a bike in future so you can use the future value formula to calculate it:
Future value = Amount * (1 + rate)^ no. of periods
= 350 * (1 - 14%)⁴
= 350 * 0.54700816
= $191.45
The rate is subtracted from 1 instead of being added to represent that the value is decreasing not increasing.

What is the area of a regular pentagon with a side length of 10 inches and a distance from the center to a vertex of 10 inches? Round your answer to the nearest tenth.
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].
A store clerk put out packages of chocolate chip and oatmeal cookies on a shelf. The ratio of the number of packages of oatmeal cookies to total cookies on the shelf was 3 to 10.
Which number could be the number of packages of chocolate chip cookies the clerk put out on the shelf?
a 9
b 6
c 20
d 14
Answer:
D) 14
Step-by-step explanation:
If the ratio of oatmeal to total cookies is 3:10 and chocolate chip is the only other type of cookie, that means there’s 7 choco chip for every 10 total cookies. Assuming the clerk put the cookies out in packages or something of 10, the answer would be D since it is the only answer that is a multiple of 7

Answer:
D.
Step-by-step explanation:
State if the triangles in each pair are similar. If so, state how you know they are similar
A.They are similar by the AA rule
B.They are not similar
C.They are similar by the SSS rule
Answer: C. They are similar by the SSS rule
Step-by-step explanation:
There are three ways to prove triangle similar
AA similar theorem--Two corresponding angles in two triangles are the congruentSAS similar theorem--Two corresponding pairs of sides of two triangles are proportional, and the angle in between two sides are congruentSSS similar theorem--All corresponding sides of two triangles are proportional--------------------------------------------------------------------------------
Here, we see in the figures, the side lengths are given, and there are no angles. So, supposedly, we are going to use SSS similar theorem.

M varies directly as n, and m=14 when n=7 a) Write an equation that relates m and n b) find m when n=16 c) find n when m=30
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.
What is Expression?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.
