is y = x proportional
Answer:
yes
Step-by-step explanation:
6x + y = 20
x - 4y = -5
The value of [tex]x[/tex] is [tex]3[/tex] and [tex]y[/tex] is [tex]2[/tex]
The given equations are
[tex]6x+y=20\\x-4y=-5[/tex]
We need to find the value of [tex]x[/tex] and [tex]y[/tex]
First let's take equation [tex]2[/tex] and we can simplify it
[tex]x-4y=-5\\x=-5+4y[/tex]
Now, let's substitute the value of [tex]x[/tex] in equation [tex]1[/tex], that is
[tex]6x+y=20\\6(-5+4y)+y=20[/tex]
We can open the bracket and simplify
[tex]=-30+24y+y=20\\=-30+25y=20\\=25y=20+30\\=25y=50\\=y=\frac{50}{25} \\y=2[/tex]
Now we can substitute the value of [tex]y[/tex] in equation [tex]x-4y=-5[/tex]
[tex]x-4(2)=-5\\x-8=-5\\x=-5+8\\x=3[/tex]
The complete question is find the value of [tex]x[/tex] and [tex]y[/tex] from the given equations.

For each of these variables, which of the mean, median, or mode would be the best choice to describe the typical behavior of the variable? Why?
Sales prices of houses
Age of 1st graders
Heights of women
In the case of Typical behavior of the sales prices of houses median is the best term. In the case of Ages of 1st graders mean is the best way of central tendency and for Heights of women mode is the best measure.
First of all we have to know the Mean, median and mode. The mean of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.
In the case of typical behavior of the variable sales price of houses, the Median will be the best measure of central tendency because the median will not get affected by the higher/lower prices of houses.
The age of each kid will be almost the same. In order to represent the typical behavior of the variable Age of 1st graders, the mean will be the best measure of central tendency.
Incase of Heights of women, the mode will be the best measure of central tendency as it will describe the height that most of the females have.

have anyone figured it out yet? pleaseee i need answer
The probability of choosing an even number that is greater than or equal to 4 is 0.3333 or 33.33%.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Tiles with the numbers 1 through 9 are placed in a bag.
The total outcomes will be
Total outcome = 9 {1, 2, 3, 4, 5, 6, 7, 8, 9}
The probability of choosing an even number that is greater than or equal to 4 will be
Favorable event = 3 {4, 6, 8}

The total number of workers in the factory is = 240.
It is given that,
Male = 85%
Female = 36
If we assume that the total workers account for 100%, then we know that Female workers account for 15% of the workforce (as 100-85= 15).
Now,
=> 15% = 36
If, 1% = 36/15
then, 100% = 36/15*100
= 12*20
= 240.
Therefore, the answer is 240.

What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same constant ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
Given, A sequence is represented by the explicit formula aₙ = - 24 - 3n.
We know, Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.
Therefore, To find a₄₀, we'll simply replace n with 40.
So, a₄₀ = - 24 - 3(40).
a₄₀ = - 24 - 120.

What is the value of x if the points A 4 3 and B x 5 are on the circle with Centre O 2 3?
The value of x with points A ( 4, 3 ) and B ( x ,5 ) on the circle and O(2,3) as centre is equal to 2.
As given in the question,
Points A(4,3 ) and B ( x, 5 ) are on the circle.
Centre of the circle is represented by O( 2,3)
OA and OB represents the radius of the circle.
This implies
OA = OB
Using distance formula we get,
√ ( 2 - 4 )² + ( 3 - 3 )² = √ ( 2 - x )² + ( 3 - 5 )²
⇒ √ 4 + 0 = √ 4 - 4x + x² + 4
⇒4 = 4 - 4x + x² + 4
⇒4 - 4x + x² = 0
⇒ ( x - 2 )² = 0
⇒ x - 2 = 0
⇒ x = 2
Therefore, the value of x for the given point of the circle is equal to 2.
The above question is incomplete , the complete question is :
What is the value of x , if the points A(4, 3) & B(x, 5) are on the circles with Centre O(2, 3), find the value of x.

what is inequality ?A relationship between two expressions or values that is not equal is known as an inequality in mathematics. Inequality follows imbalance, therefore. In mathematics, an inequality makes a connection between two values that are not equal. Egality and inequality are different. Different inequalities are employed to contrast values of all sizes. By changing the two sides until only the variables are left, one can solve many straightforward inequalities. But a variety of factors support inequality: Negative values are split or added on either side. Switch between the left and right.

Answer:Bilquis finds some nickels and quarters in her piggy bank. How much money (in
cents) does she have if she has 7 nickels and 5 quarters? How much money
does she have if she has n nickels and q quarters?
Step-by-step explanation:
Answer: 157 cents ($1.57)
Step-by-step explanation: Nickels are worth 5 cents each, so 5 cents times 7 nickels equals a total of 35 cents. After that, we have 5 quarters which cost 25 cents each, so 25 cents times 5 quarters equals a total of 125 cents. Combine these two products, and you get 157 cents. Or, if you want it in dollars, you can divide 157 by 100 cents (there are 100 cents in a dollar) and end up with $1,57.

chance of getting a job offer from company B, and a 30% chance of getting a job offer from both companies A and B.
What is the probability of Johnny not getting a job offer from either company?
The probability of Johnny not getting a job offer from either company is 0.8
Suppose Johnny applied for a job at companies A and B.
Through extensive research, Johnny determined he has a 60% chance of getting a job offer from company A,
A = 0.6
a 50% chance of getting a job offer from company B,
B = 0.5
and a 30% chance of getting a job offer from both companies A and B.
What is the probability of Johnny not getting a job offer from either company?
Suppose, probability of an event A occurring is P(A)
and that of is B IS P(B)
P(A) = 0.6
and
P(B)= 0.5
probability of either or P(AUB)=0.3
Now we need to find the probability of neither nor, which is
P(A∪B) = P(A) + P(B) - P(A∩B)
P(A∩B) = P(A) + P(B) -P(A∪B)
= 0.6 + 0.5 - 0.3
= 0.8
Now the events are mutually exclusive, so
Therefore, the probability of neither nor is 0.8
The probability of Johnny not getting a job offer from either company is 0.8

What is the factor of the dilation?
The scale factor of dilation explains how the size of the figure has changed. An expansion has a scale factor of x > 1 (greater than 1).
A reduction is a scale factor that is 0 <1 (higher than 0 but less than 1).
Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. However, there is a variation in the shape's size.
A dilatation that results in a reduction (imagine shrinking) or an expansion (think stretching) produces a smaller or bigger picture, respectively.
The picture is reduced if the scale factor is between 0 and 1.
The picture is an enlargement if the scale factor is larger than 1.

What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Find BC. AB=25 AC=25 BD=3x+4 DC=4x-5
Answer:
b
Step-by-step explanation:
Since AB = AC = 25, then the triangle is isosceles
Segment AD bisects BC at right angles , then
CD = BD, that is
4x - 5 = 3x + 4 ( subtract 3x from both sides )
x - 5 = 4 ( add 5 to both sides )
x = 9
Then
BC = 3x + 4 + 4x - 5 = 7x - 1 = 7(9) - 1 = 63 - 1 = 62
Answer:
3x+4=4x-5
3x‐(4x)=-5+-4
x=9
plug in 9 for x on both sides and add them together to find BC
each side is 31,
answer is 62.
