Step-by-step explanation:
Let the first session be y =20 + 30x .................. equation 1
Let the second session be y = 10 + 35x .............. equation 2
equate the two functions
20 + 30x = 10 + 35x
y = 20 - 10 +30x - 35x
y = 10 -5x
Find the y intercept (that is where y = 0)
10-5x = 0
5x =10
x = 2
substitute x = 2 into equation 1 and 2
y =20 + 30(2) = 80
y = 10 + 35(2) =80
Notice that when you plot the graph for equ. 1 and equ. 2 , it intercepts at x =2 and y =80 (2, 80)

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

The rate to rent a truck for a day is a one-time fee of $35 and $0.20 per mile.
Write an expression to model this situation.
How far could you travel if you drove 40 miles?
Answer: y= $0.20x + $35 or y= $0.20 * 40 + $35 (Depending on what you mean)
Step-by-step explanation:
The equation for these types of problems is y = mx + b.
M would be $0.20, because that is the value that can repeat, based on x. For example, if this was 2 dollars per mile (m) for 3 miles, (x) than y, the total amount for mx would amount to 6 dollars.
Now, 35$ Is a one time fee (b), so you can add that separately to $0.20x.
If you plug everything in, you would get y= $0.20x + $35.
I am not very sure about what you mean by “ How far you could you travel if you drove 40 miles”, but if you mean how much would you pay to drive 40 miles, I can help there.
Now that we know x would be the amount of miles, we can plug that into the equation.
You would get y= $0.20 * 40 + $35.

Find the LCM of 2 and 3, which is 6. Now make the denominators for both fractions 6, and multiply the numerators by whatever you multiply the denominator to get to 6.
You know that to get 3 to 6, you multiply by 2. So then you also have to multiply the neumerator for that fraction by 2 as well. 2x2= 4, so the new neumeraator is 4
Now for the next fraction. To get from 2 to six, you multiply by 3. So multiply the neumerator by 3. 1x3= 3 , so the new neumerator is 3.
4/6+ 3/6= 7/6
Step 3: Add & Simplify
5+7/6= 5+1 1/6= 6 1/6.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

The numbers 1-6 are written on slips of paper and placed in a bag. Megan draws two numbers in a row without replacement. What is the probability of Megan selecting an even number followed by a 3?
A) 1/6
B) 1/10
The probability of Megan selecting an even number followed by a 3 will be 1/10. Then the correct option is B.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
Paper slips with the numbers 1-6 are collected in a bag. Without substitution, Megan draws two numbers consecutively.
The probability is given as,
P = (1/6) x (3/5)
P = (1/2) x (1/5)
P = 1/10
The probability of Megan selecting an even number followed by a 3 will be 1/10. Then the correct option is B.

Rosena bought an 8 pack of donuts to share with her friend at school. The donuts cost $28.00 all together. What is the unit rate for the donuts in $/donuts?
Answer:
$3.50/donut
Step-by-step explanation:
Since Rosena bought an 8-pack of donuts for $28.00, we can say that the price of $28.00 corresponds with this pack.
The unit rate represents the price per donut, assuming a constant proportion.
The pack that Rosena bought contains 8 donuts. Therefore, to find the price of one donut, divide the price that corresponds with the 8-donut pack by 8, because \(8\div 8=1\).
The price of the 8-pack of donuts was \(\$28.00\). Diving by 8, we have:
\(\frac{\$28.00}{8}=\boxed{\$3.50}\)
Therefore, the unit rate for the donuts is $3.50/donut.
Answer:
$3.5
28/8 = 3.5
