Solve the system of linear equations by elimination. Check your solutions.
-5x + 3y = -6
9x - 4y = 1
Answers
We can divide both sides of the equation by 43 to solve for x:
90x / 43 - 47y / 43 = -49 / 43
x = -49/43
We can substitute this value for x back into either of the original equations to find y. Let's substitute it into the first equation:
-5x + 3y = -6
(-5 * -49/43) + 3y = -6
y = (-6 + 5 * 49/43) / 3
y = 17/43
The solution to the system of equations is (x, y) = (-49/43, 17/43).
To check our solution, we can substitute the values we found for x and y back into the original equations and see if they hold true.
In the first equation, -5x + 3y = -6, substituting the values we found for x and y gives us:
(-5 * -49/43) + (3 * 17/43) = -6
This simplifies to -6 = -6, which is true, so the solution holds for this equation.
In the second equation, 9x - 4y = 1, substituting the values we found for x and y gives us:
(9 * -49/43) - (4 * 17/43) = 1
This simplifies to -1 = -1, which is true, so the solution holds for this equation as well.
Therefore, the solution (x, y) = (-49/43, 17/43) is correct.
-45x+3*9y=-6*9
Equation1: -45x+27y=-54
Equation2: -45x-(4*(-5))y=1*(-5)
-45x+20y=-5
Equation1-equation2= 27y-20y=-54-(-5)
7y=-49
Y=-7
9x-4*(-7)=1
9x=1-28

The time for 22 leg-press reps is 11.9 seconds.
Step-by-step explanation:The lines of best fit is the trend line of the dataset.
The equation of line of best fit is y = 0.120x + 9.274The time for 22 leg-press reps is 11.9 seconds(A) The equation of the line of best fitThe table is given as —
(x) : 12 32 7 26 28 15 1
(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5
To determine the equation of line of best fit, we make use of a regression calculator.
Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)
(B) The number of seconds for 22 leg-press repsThis means that x = 22.
So, we have:
y = 0.120 * 22 + 9.274
= 2.640 + 9.274
= 11.914
(Approximate to the nearest hundredths)
= 11.9
Hence, the time for 22 leg-press reps is 11.9 seconds.

Julie's income for 16 hours is $192. Julie takes only 24 hours to earn $288. The rate is $12 for each hour.
Given
Loren and Julie have different part-time jobs after school.
They are both paid at a constant rate of dollars per hour.
The income of Julie is $36 in 3 hours.
For 1 hour, Julie earns $12.
Thus the rate of Julie is $12 per hour.
For the 16 hours, Julie's income will be.
Julie's income for 16 hours = 12 x 16
Julie's income for 16 hours = $192
Julie's income for 16 hours is $192.
Julie takes time to earn $228 will be
Thus, Julie takes only 24 hours to earn $288.
Julie earns $72 for 6 hours of work, and $252 for 21 hours of work. This is because she gets paid 12 dollars for every hour she works

Find the lower quartile and upper quartile of the data set. 10, 11, 13,18,19,21,22,25,27,30,32
Answers
The lower quartile value is 13 and the upper quartile value is 27.
What is a Quartile?
A quartile divides the data set into four equal halves, that is, each set has an equal number of terms. The quartiles are given by Q₁(the lower quartile value), Q₂ (the median), Q₃ (the upper quartile value).
We first arrange the data set in ascending order. Here, the data set is already in ascending order, that is, 10,11,13,18,19,21,22,25,27,30,32.
So we will divide the above set into two equal halves. As the given set has 11 terms,
So the median is [tex]\frac{n+1}{2}[/tex] where n is the number of terms.
We have n=11
⇒ Median= [tex]\frac{11+1}{2}[/tex] th term
= 6th term
⇒ Median= 21
Now the data to the left side of the median value will give the lower quartile and the data to the right will give the upper quartile.
The data to the left of median value 21 is 10,11,13,18,19.
The median value of this data will give the lower quartile value.
Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term
=13
⇒Lower quartile is 13.
The data to the right of the median value 21 is 22,25,27,30,32
The median value of this data will give the upper quartile value.
Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term
= 27
⇒Upper quartile is 27.
The correct answer is lower quartile= 13, upper quartile = 27

Answer:
#5 = option a (129.38 miles):
We are told that the cities are 17.25 inches apart, and that 2 inches equal 15 miles. First we have to divide 17.25 inches by 2 we end up with 8.62500 inches (not simplified yet). Next, we just take 8.62500 inches and multiply that with 15, which leaves us with 129.37500 inches. Then we just round that to the nearest hundredth which will give us 129.38 inches which means 129.38 miles as well!
#2 = option a (2.4 inches)
We know that bigger rectangle's length is 16 inch and that smaller rectangle's length is 3.2 inches. We just have to calculate the decrease of the length and we do that by dividing. We have to do 16 inches divided by 3.2 inches which equals 5. (You can double check that by multiplying 3.2 inches by 5 which would equal 16 inches) Now to find the width of the smaller rectangle, we just have to divide the width of the bigger rectangle, which is 12 inches, by 5 which would give us 2.4 inches!
#4 = ?
#6 = option c (7.2cm)
So basically I just did 25cm divided by 10cm which equals 2.5cm. (You can also do 25cm divided by 2.5cm to get 10cm if you want to double check). Then I just did 18cm divided by 2.5 cm which led me to the answer 7.2cm)
#3 = ?
Answer: A
Step-by-step explanation: 17.25/2=8.652
8.652*15=129...
rounded it would be equivalent to answer choice A.
