Answer:
x= -2
y= -4
Step-by-step explanation:
1) solve for y in 5x-y= -6
which would be y= 5x+6
2) substitute that in for y in the second equation
which would be 10x+3(5x+6)= -32
3) solve that new equation
which would be x= -2
4) plug x= -2 into either equation (the shorter equation is the one i chose)
which would be 5(-2) - y = -6
5) solve that new equation
which would be y= -4

Step-by-step explanation:
so we grab the fraction:
6 1/2%
make it a decimal instead of a fraction
6.5%
divide it by 100 to get
6.5/100
and multiply it by 2 because decimals have no place inside fractions lol

[Calculus] find average velocity given position of particle. Show steps, please!
Answer:
C
Step-by-step explanation:
Since we are given the position function, the average velocity will simply be the average slope of the position function.
We want to find the average velocity for time 0≤t≤3.
So, our endpoints are t = 0 and t = 3.
By substitution, the position of the particle at those times are:
[tex]x(0)=-5(0)^2=0\text{ and } \\\\ x(3)=-5(3)^2=-45[/tex]
So, we have the two points (0, 0) and (3, -45).
Then by the slope formula, we acquire that:
[tex]\displaystyle m=\frac{(-45)-(0)}{(3)-0}=\frac{-45}{3}=-15[/tex]
So, the average velocity of the particle is about -15.
This implies that the particle was mainly moving backwards for time 0≤t≤3.
Hence, our final answer is C.
*If you differentiated first and then did the steps above, then you found the average acceleration of the particle (in this case it stays constant), not the average velocity. Remember that the slope of the position graph is velocity, and the slope of the velocity graph is acceleration!

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 18 Pennies13 Dimes 18 Nickels13 Quarters What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, another nickel
Answer:
[tex]P(Nickel\ and\ Nickel) = 0.08091[/tex]
Step-by-step explanation:
Given
[tex]Pennies = 18[/tex]
[tex]Dimes = 13[/tex]
[tex]Nickels = 18[/tex]
[tex]Quarters = 13[/tex]
Required
Probability of selecting 2 nickels without replacement
This can be represented as: [tex]P(Nickel\ and\ Nickel)[/tex]
The solution is as follows
[tex]P(Nickel\ and\ Nickel) = \frac{Nickel}{Total}*\frac{Nickel-1}{Total-1}[/tex]
The second nickel is reduced by 1 because the first nickel was not replaced and this also reduces the total by 1
So, we have:
[tex]P(Nickel\ and\ Nickel) = \frac{18}{62}*\frac{18-1}{62-1}[/tex]
[tex]P(Nickel\ and\ Nickel) = \frac{18}{62}*\frac{17}{61}[/tex]
[tex]P(Nickel\ and\ Nickel) = \frac{18*17}{62*61}[/tex]
[tex]P(Nickel\ and\ Nickel) = \frac{306}{3782}[/tex]
[tex]P(Nickel\ and\ Nickel) = 0.08091[/tex]
Practice using graphs of equivalent ratios. On a coordinate plane, point (2, 3) is plotted.A 2-column table with 3 rows. Column 1 is labeled x with entries 2, blank, blank. Column 2 is labeled y with entries 3, blank, blank. The table shows one point from the given graph. How could you find more ordered pairs to create a graph and table of equivalent fractions? Check all that apply. Include the point (0, 0), which is on every graph of equivalent ratios. Multiply both 2 and 3 by 4. Multiply 2 by 2 and 3 by 3. Start at the point on the grid. Move right 2 and up 3 and plot the point. Multiply 2 by 3 and 3 by 2.

Determine which car gets the better gas mileage. Car A: Distance (miles) 400 Gallons used: 12 Car B: Distance (miles) 440 Gallons used: 15
So on one galon of gas car A would travel 33 1/3 miles, while car B would travel 29 1/3 miles. Answer: Car A
A: 400 / 12 = 33 1/3
B: 440 / 15 = 29 1/3

What is Proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
We have the Table,
With 8 tea bags, 2 Quartz of Iced Tea made.
As, there is proportionality between two values.
So, 16 / 4= 24 / x
4 = 24 / x
x = 24/4
x= 6
Hence, For 24 Tea bags 6 quarts of iced tea that can be made.

What is the value of x^6+y^2x 6 +y 2 x, start superscript, 6, end superscript, plus, y, squared when x=1x=1x, equals, 1 and y=11y=11y, equals, 11?
Try 122.
Step-by-step explanation:
Since x = 1, x^6 = 1.
Since y = 11, 11^2 = 121.
1 + 121 = 122.
So, the value of x ^ 6 + y ^ 2 = 122.Answer:82

One step equation
-104=8x
Answer:
The answer you gave can only be solved if you know what the Variable is.
Step-by-step explanation:
A one-step equation is an algebraic equation you can solve in only one step. Once you've solved it, you've found the value of the variable that makes the equation true. To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself.
