Answer:
Step-by-step explanation: X and Y represent the digits.
The tens digit is twice the units digit.
The digit in the Tens place has 10× its base value, so we can set up equations to model the information given.
10x +y 10y +x are Original & Reversed numbers
X = 2y means the Tens digits is twice the units digit.
10y + x +2 = 10x +y - 34 models the statement: The reversed number plus two is 34 less than the original number.
Substitute 2y for x to solve for y
10y +2y +2= 10(2y) + y -34
Distribute and combine like terms
12y + 2 = 20y +y - 34
34 +2 = 21y -12y
36 = 9y Divide both sides to find the value of y.
4 = y
X = 2(4) Substitute 4 for y to find x
X = 8
Original number: 84 Reversed number: 48
Substitute into equation model
48 +2= 84 -34
50 = 50

George wants to rent a car for a road trip with his friends. He checked the rentals with two companies. Company A charges a non-refundable fee of $50 and then also $150 for each day. Company B charges using the function 50(2+1). Compare the two functions. Which function has a great rate of change?
Answer:
Company A has a greater daily rate
Step-by-step explanation:
Given
Company A
[tex]Base\ Charges=\$50[/tex]
[tex]Daily\ Rate = \$150[/tex]
Company B
[tex]f(x) = 50(2x +1)[/tex]
Required
Determine the company with greater rate
Simplify the expression of company B
[tex]f(x) = 50(2x +1)[/tex]
[tex]f(x) = 50 * 2x + 50 * 1[/tex]
[tex]f(x) = 100x + 50[/tex]
In a linear function:
[tex]f(x) = mx + b[/tex]
m represents the rates.
This implies that the rate of company B is:
[tex]Rate =100[/tex]
and the rate of company A is
[tex]Daily\ Rate = \$150[/tex]
By comparison:
Company A has a greater daily rate

Answer:
The equation a parallel line will be:
[tex]y=\frac{4}{3}x-9[/tex]
Hence, option B is correct.
Step-by-step explanation:
Given the equation
[tex]8x-6y=7[/tex]
Writing the line into the slope-intercept form
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so
[tex]8x-6y=7[/tex]
[tex]6y\:=\:8x-7[/tex]
Dividing both sides by 6
[tex]y=\frac{4}{3}x-\frac{7}{6}[/tex]
comparing with the slope-intercept form
Thus, the slope of the line = m = 4/3
We know that the parallel lines have the same slope.
Thus, the slope of the parallel line is also 4/3
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 4/3 and the point (6, -1)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-1\right)=\frac{4}{3}\left(x-6\right)[/tex]
[tex]y+1=\frac{4}{3}\left(x-6\right)[/tex]
Subtract 1 from both sides
[tex]y+1-1=\frac{4}{3}\left(x-6\right)-1[/tex]
[tex]y=\frac{4}{3}x-9[/tex]
Thus, the equation a parallel line will be:
[tex]y=\frac{4}{3}x-9[/tex]
Hence, option B is correct.
what is the answer to this?
Answer:
Well in a standard equation you have y=mx + b Mx is the slope and b is the y-intercept So take a shot and solve it now!Given f(x) = -2 and g(x) = 5x - 6, find h(x) = f(x) ⋅ g(x)

how do i find a slope?
Answer:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

The accounts payable clerk writes 5 checks every 50 minutes. How many checks will he use in 170 minutes?
Answer:
17
Step-by-step explanation:
5/50= x/170 multiply 5x170 divide that answer by 50. or bc u know that 5x10 = 50 u could divide 170 by 10 and still get 17
Answer:
17
Step-by-step explanation:
17 because they write five checks each 50 minutes so it means that every 10 minutes on the check is created incel I went 50 +50+50 =150 And you can't add another 50 so than in 20 minutes to checks can be made and then so I made the conclusion that there can be 17 checks made

7 is the right answer.The Math Club is raising money so they can attend a local competition next month. They have already raised $125 and they are selling candy bars to raise the rest of the money needed. Each candy bar sells for $2.50.
Answer: 100 candy bars
Step-by-step explanation:
You did not include the question but judging by the progression I can assume that the question is along the lines of how many candy bars they will need to sell to reach their target.
You did not include the amount they have to raise as well so let us assume that number is $375.
Assuming they have to raise $375 and they have already raised $125, the amount left to be raised is:
= 375 - 125
= $250
With each candy bar selling at $2.50, the number of candy bars they will need to sell is:
= 250/ 2.50
= 100 candy bars
You should use this process to find the answer to your question.

A traffic engineer records a sample of the types of vehicles that cross a bridge. She counts 112 passenger cars, 18 light trucks, and 20 heavy trucks.
What is the APPROXIMATE probability that a random vehicle crossing the bridge is a passenger car?
Answer:
The approximate probability that a random vehicle is a passenger car is 74.67%
Step-by-step explanation:
Probability
The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.
We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:
[tex]\displaystyle p=\frac{112}{150}[/tex]
p = 0.7467
p = 74.67%
The approximate probability that a random vehicle is a passenger car is 74.67%

3. A number written in scientific notation is a product of two factors.
One of the factors is a power of 10. Describe the other factor.
Answer:
You can find the product of a number and a power
of 10 by moving the decimal point of the number.
– If the exponent is positive, move the decimal point to
the right.
– If the exponent is negative, move the decimal point to
the left.
• You may need to write zeros to the right or left of
the number in order to move the decimal point.
