Arrange the systems of equations that have a single solution in increasing order of the x-values in their solutions. 2x + y = 10 x − 3y = -2 x + 2y = 5 2x + y = 4 x + 3y = 5 6x − y = 11 2x + y = 10 -6x − 3y = -2
Answer: IN ORDER
x + 2y = 5
2x + y = 4
This equation equals to x = 1 and y = 2
x + 3y = 5
6x - y = 11
This equation equals to x = 2 and y = 1
2x + y = 10
x - 3y = -2
This equation equals to x = 4 and y = 2
Step-by-step explanation:
It obvously cannot be:
2x + y = 10
-6x - 3y = -2
Because this equation has NO SOLUTION.

The graph shows the amount of money paid when purchasing bags of caramel corn at the zoo: A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 10. Four points are shown on the graph on ordered pairs 0, 0 and 1, 3 and 2, 6 and 3, 9. These points are joined by a line. The label on the x-axis is Bags of caramel corn. The title on the y-axis is Total cost in dollars. What does the point (0, 0) on the graph represent? (4 points)
Group of answer choices
A. The cost of zero bags of caramel corn
B. The cost of one bag of caramel corn
C. The cost of two bags of caramel corn
D. The cost of three bags of caramel corn

Answer:
no
Step-by-step explanation:
Answer:
I am the brainliest!
Step-by-step explanation:
Although 6 and 3 are on opposite sides of sea level, or 0, they are not opposites because they are unequal distances from 0.

What is the y-intercept of the function f(x) = –negative StartFraction 2 Over 9 EndFraction.x + ? –negative StartFraction 2 Over 9 EndFraction. –negative StartFraction 1 Over 3 EndFraction. StartFraction 1 Over 3 EndFraction. StartFraction 2 Over 9 EndFraction.
Answer:
Third option
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope of the line and "b" is the y-intercept.
Given the function f(x):
Since , you can rewrite it:
You can identify that:
Therefore, you can determine that the y-intercept of the given function is:
Observe that this matches with the third option.

Adriana bought a computer and three pieces of software. She spent a total of $1,220. The computer cost $995, and each piece of software costs the same price. Write and solve the equation needed to answer this question
And it's not f'(x) = (0.1x - 1)^2 + 1)
Answer:
A
Step-by-step explanation:
To reflect a function over the x-axis, we multiply the function by -1. So, if f(x) is the original function, then -f(x) is the function across the x-axis.
To reflect a function over the y-axis, we multiply the inside of the function by -1. So, if f(x) is the original function, then f(-x) is the function across the x-axis.
We have:
[tex]f(x)=(x-1)^2+1[/tex]
Then:
[tex]f(-x)=(-x-1)^2+1=f ^\prime(x)[/tex]
We can see that the choice that resembles this is A. If we let:
[tex]f(-4x)=(-4x-1)^2+1[/tex]
This is a reflection over the y-axis followed by a horizontal compression by a factor of 4.
Hence, our answer is A.

What is the equation of the line? Hint: Use the form y = mx.
Answer:
slope is 4, so m=4
Step-by-step explanation:
y=4x+0
You do not need to include the 0, but that would be in the place of b.
If you need a coordinate for x and y, use (4,1)
Use the associative property to write an expression equivelent to (w + 9)+3
Answer:
w+ (9+3)
Step-by-step explanation:
pretty simple if I remember how to use that property
Answer:
The equivalent expression for the given expression (w+9)+3 using associative property is w + 12
Solution:
Given that, expression is ( w + 9 ) + 3
We have to find how do we can use the associative property to write an expression equivalent to ( w + 9 ) + 3
The associative property states that you can add or multiply regardless of how the numbers are grouped
By above definition, we get
(a + b) + c = a + (b + c)
So, now let us apply the above property to the given expression,
Then, ( w + 9 ) + 3 = w + ( 9 + 3 ) = w + 12
Hence, the equivalent expression for the given expression is w + 12
Step-by-step explanation:
Its the same thing but I put it it the comments bc why not
