What is the solution for this system x+y=6 2x+4y=20
Answer:
It is a linear equation
solving by substitution method
x + y =6 ------ eqn 1
2x + 4y =20 -------- eqn 2
x = 6 - y ------ eqn 3
putting the value of x from eqn 3. into eqn 2.
2(6-y) +4y =20
12 - 2y + 4y =20
12 +2y =20
2y = 20-12
2y = 8
2y / 2 =8/2
y =4
put the value of y into eqn 3
x =6 - y
x = 6 - 4
x = 2
Therefore x = 2, y= 4
hat is the image point of (-2,5)(−2,5) after a translation left 5 units and up 3 units?
Answer:
(-7,8)
Step-by-step explanation:
5 units left on a coordinate plane is negative with just means you are adding two negative numbers. (x-axis) and up 3 units (adding because you are going up) which would be the y-axis
On a scale drawing of a museum, two water fountains are 10 inches apart. The actual distance between them is 400 feet. On the same drawing, the distance between two exhibits is 3. 125 inches. What is the actual distance between these two exhibits? 13 feet 125 feet 313 feet 425 feet.
Scale factor is the ratio of representation measurement of the figure to the original figures.
The actual distance between these two exhibits is 125 feet. Thus the option 2 is the correct option.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
Given information-
The distance between the two water fountains is 10 inches on the scale drawing of the museum.
The actual distance between the two water fountains is 400 inches.
The distance between two exhibits is 3.125 inches on the same scale drawing of the museum.
The scale factor of the distance of water museum in the drawing to the actual distance is,
[tex]r=\dfrac{10}{400} \\r=\dfrac{1}{40}[/tex]
Thus the scale factor of the distance of water museum in the drawing to the actual distance is 1/40.
As the the distance between two exhibits is measured on the same scale of drawing. Thus the scale factor in this case also be same.
Let the actual distance between these two exhibits is x feet. Thus,
[tex]\dfrac{1}{40} =\dfrac{3.125}{x}\\x=125\rm ft[/tex]
Hence, the actual distance between these two exhibits is 125 feet. Thus the option 2 is the correct option.

Your group has 10 pennies and 10 nickels. Use these pennies and nickels to solve the following problems.
1. You have a total of 11 coins. The total value of the 11 coins is 23 cents.
What is the only possible combination of pennies and nickels?
Answer:
p=8
n=3
Step-by-step explanation:
let number of pennies=p
number of nickels=n
p+n=11
n=11-p
1*p+5*n=23
p+5(11-p)=23
p+55-5p=23
55-4p=23
4p=55-23=32
p=32/4=8
n=11-8=3
You are buying an Apple Watch for $100. The watch is currently 75% off and you have a 25% off coupon! Will you get the item for free? Explain your thinking.
Answer:
No
Step-by-step explanation:
Because the watch is selling for 75% off, the discounted price will be
[tex]100(1-75\%)\\=100*0.25\\=25[/tex]($)
Then, when you apply your coupon, the new cost will be
[tex]25(1-25\%)\\=25*0.75\\=18.75[/tex]($)
So you'll still pay $18.75.

Which explicit formula describes the arithmetic
sequence {19, 14, 9, 4, ...}
Answer:
[tex]a_n=19+(n-1)(-5)[/tex]
Step-by-step explanation:
The explicit formula for an arithmetic sequence is [tex]a_n=a_1+(n-1)d[/tex] where [tex]a_n[/tex] is the [tex]n[/tex]th term and [tex]d[/tex] is the common difference.
In this problem, we can see that the first term of the sequence is [tex]a_1=19[/tex] and the common difference is [tex]d=-5[/tex] since 5 is being subtracted each consecutive term.
Therefore, the explicit formula that describes the given arithmetic sequence is [tex]a_n=19+(n-1)(-5)[/tex]
Answer:
option 2
Step-by-step explanation:
Let { a1, a2, a3, a4, ... } be the sequence.
now the 1st term (a1) will have a value when n = 1.
similarly, all the other terms will have the values given when we substitute their respective n values into the explicit formula or fibonacci sequence.
thus, check if the 1st term is 19 by using option 2
an = 19 + (n-1)(-5)
an = 19 + (n-1)(-5) ....n = 1
an = 19 + (n-1)(-5) ....n = 1 a1 = 19 + (1-1)(-5) = 19 + 0 = 19. so it's accurate so far.
next, check a2 where n = 2.
a2 = 19 + (2-1)(-5) = 19 - 5 = 14. ....
n = 3
a3 = 19 + (3-1)(-5) = 19 - 10 = 9.
hence the conclusion from this pattern.

How to take a line in desmos and reflect it over y axis and find equation.
Answer:
Reflecting a function over any axis can be complicated if you do not know the proper way to do it, so I am going to use examples to show you.
If f(x)=x is your normal function, then flipping it across the y-axis would look like f(x)=-x.
Step-by-step explanation:
Placing a - sign before the X will make it flip across the y-axis. After the X, and it flips across the X-axis.
