The graph representing the solution to the system of inequalities y < 2x - 5 and y > -3x + 1 would have a dashed line for the first inequality and a solid line for the second one, with the intersected shading to the left of the lines.
Explanation:The student's question centers around identifying which graph depicts the solution to the given system of linear inequalities: y < 2x - 5 and y > -3x + 1. The solution to a system of inequalities is represented by the area of intersection between the two shaded regions of the graphs. The first inequality, y < 2x - 5, is a line with a positive slope that passes through (0, -5) and the shading is below the line because 'y' is less than the expression on the right. The second inequality, y > -3x + 1, is a line with a negative slope that passes through (0, 1), and the shading is above the line because 'y' is greater than the expression on the right. Based on these conditions, the correct graph would be the one with a dashed line (indicating 'less than' or 'greater than' but not 'equal to') for the first equation and a solid line (indicating 'less than or equal to' or 'greater than or equal to') for the second equation where the shading on the left side of the lines intersect.
Remember, the slope of a line indicates how steep the line is and is calculated by rise over run. The y-intercept of a line is where the line crosses the y-axis. These key features, along with the type of inequality symbol, determine where and how to shade the graph for a system of linear inequalities.

The current ratio (assets/liabilities) of company X is 2.9. Given that the current assets are $377000, find the current liabilities:
Current liabilities = 130000
The board of directors determines that the current ratio must never be below 2.6. What is the maximum amount that the company can borrow?
Answer:
The maximum amount that the company X can borrow is $ 145,000
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Current ratio of assets/liabilities = 2.9
Current assets = $ 377,000
Current liabilities = Currents assets/Ratio = 377,000/2.9 = $ 130,000
2. The board of directors determines that the current ratio must never be below 2.6. What is the maximum amount that the company can borrow?
Desired ratio of assets/liabilities = 2.6
Current assets = $ 377,000
Desired liabilities = $ Current assets/Ratio = 377,000/2.6 = $ 145,000
The maximum amount that the company X can borrow is $ 145,000

The fraction 3/5 makes only the fourth equation true when added with the existing fractions. The first three equations do not yield true results when 3/5 is added.
Explanation:In Mathematics, when dealing with fractions, we need to maintain the rules of basic arithmetic, meaning that equal sums must be identical on both sides of the equation. Let's check each of these equations with the fraction 3/5:
Equation 1: 7/20 + 3/5 = 14/20 + 12/20 = 26/20 ≠ 19/20. So, the answer is 'No'.
Equation 2: 3/5 + 3/10 = 12/20 + 6/20 = 18/20 ≠ 3/15. So the answer is 'No'.
Equation 3: 1/2 + 2/3 ≠ 3/5. So the answer is 'No'.
Equation 4: 1/10 + 1/2 = 2/20 + 10/20 = 12/20 = 3/5. So the answer is 'Yes'.

$50 is invested biweekly in an
ordinary simple annuity, earning
3.5% interest per annum,
compounded biweekly. What will the
value of the annuity be in 10 years?
Answer:
The value of the annuity in 10 years will be US$ 15,552.90
Step-by-step explanation:
Let's use the ordinary simple annuity formula to calculate the value of the annuity in 10 years, this way:
FV = Future value of an annuity stream
PMT = Dollar amount of each annuity payment = US% 50
r = Interest rate = 3.5% compounded biweekly = 0.035/26
n = Number of periods in which payments will be made = 26 * 10 = 260
FV = PMT * [(1 + r)ⁿ − 1]/r
Now, replacing with the real values, we have:
FV = 50 * [(1 + 0.035/26)²⁶⁰ − 1]/(0.035/26)
FV = 50 * [(1.001346154)²⁶⁰ − 1]/0.001346154
FV = 50 * 0.41873217/0.001346154
FV = 50 * 311.058148
FV = 15,552.90
We only rounded the last product to the next cent, in all the other cases we used all the decimals for the calculations.
3. Kurt's car gets 23 miles to a gallon of gasoline. He filled up his car's gas tank with g gallons. Write an expression that shows how far Kurt can drive on a tank of gasoline.
The expression D=23g shows the distance that Kurt can drive on a tank of gasoline.
Step-by-step explanation:
Given,
Distance covered by Kurt's car = 23 miles per gallon of gasoline
Kurt fills up tank of his car with g gallons.
Number of gallons in car's tank = g gallons
Distance covered by g gallons = D = Distance covered by one gallon * Number of gallons
D = 23*g
D = 23g
The expression D=23g shows the distance that Kurt can drive on a tank of gasoline.

a/3 -7=15 im confused for my son
Answer: a = 22
Step-by-step explanation: First isolate a/3 by adding 7 to both sides of the equation. That gives you a/3 = 22.
From here since a is being divided by 3, multiply both sides of the equation by 3 so a = 66. We can check our answer by substituting a 66 back in for a in the original equation and we have [tex]\frac{66}{3} - 7 =15[/tex] or 22 - 7 = 15 or 15 = 15. Since this is a true statement, our answer checks.

The solution's table in the attached figure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
Let
y ----> the price
x ----> the weight
Find the value of the proportionality constant for each ordered pair in each table
[tex]k=\frac{y}{x}[/tex]
If all the values of k are equal, then the table represents a proportional relationship between the variable x and the variable y
Table 1
For x=1.5 lb, y=$4.50 ----> [tex]k=\frac{4.5}{1.50}=3[/tex]
For x=2 lb, y=$9.00 ----> [tex]k=\frac{9.00}{2}=4.5[/tex]
The values of k are different
therefore
The table not represent a proportional relationship
Table 2
For x=10 g, y=$0.50 ----> [tex]k=\frac{0.50}{10}=0.05[/tex]
For x=15 g, y=$0.55 ----> [tex]k=\frac{0.55}{15}=0.04[/tex]
The values of k are different
therefore
The table not represent a proportional relationship
Table 3
For x=0.5 Kg, y=$0.75 ----> [tex]k=\frac{0.75}{0.5}=1.5[/tex]
For x=5 g, y=$7.50 ----> [tex]k=\frac{7.50}{5}=1.5[/tex]
The values of k are equal
therefore
The table represent a proportional relationship
Table 4
For x=1 oz, y=$2.00 ----> [tex]k=\frac{2}{1}=2[/tex]
For x=2 lb, y=$4.00
Convert lb to oz
Remember that
1 lb=16 oz
so
2 lb=2(16)=32 oz
For x=32 lb, y=$4.00 ----> [tex]k=\frac{4}{32}=0.125[/tex]
The values of k are different
therefore
The table not represent a proportional relationship
M and N are independent events. P(M | N) = 0.71. Find P(M)
Since M and N are independent events, [tex]P(M)=P(M|N)=0.71[/tex]
Step-by-step explanation:
Two events A and B are said to be independent when the probability of A happening does not depend on whether B has happened or not.
In other word, this condition can be rewrite as follows:
[tex]P(A|B)=P(A)[/tex]
where
[tex]P(A|B)[/tex] is the probability of A happening given that B has happened
[tex]P(A)[/tex] is the probability of A happening
In this problem, we have:
- M and N are independent events: so M does not depend on whether N occurs or not
Therefore,
[tex]P(M)=P(M|N)[/tex]
- Also, we know that
[tex]P(M|N)=0.71[/tex]
Therefore, it follows that
[tex]P(M)=0.71[/tex]

Which of the following could you use to solve this problem?
What is 25% of 37?
a. x/37 = 25/100
b. p = (0.25)37
c. 37/0.25 = w
d. 25/100 x 37
SELECT ALL THAT APPLY.
Answer:
A, B, D
Step-by-step explanation:
25% of 37
= 25/100 × 37
= 1/4 × 37
= 0.25 × 37
= 9.25
To find 25% of 37, you can use the equations: 'x/37 = 25/100', 'p = (0.25)37', and '25/100 x 37'. Option '37/0.25 = w' is not appropriate for finding 25% of 37.
Explanation:To find 25% of 37, you can use the following methods: a), b), and d).
These three options essentially represent how percentages can be calculated:
a) This represents 25% as a fraction (25/100) with 37 as the total (x/37). Solving for x gives you the answer. b) This signifies that 25% is converted to a decimal (0.25), and then multiplied by 37 to get the answer. d) It's similar to option a, but this time the fraction is multiplied by the total amount (25/100 * 37) directly making it a single step process.
Option c) is not suitable here because by dividing 37 by 0.25, you are finding out how many times 25% can fit into 37, not 25% of 37.

Step-by-step explanation:
Make use of the similarity relationship to find the side necessary to compute the tangent. Then make use of the tangent definition.*
__
The two triangles are given as being similar. That means corresponding sides have the same ratios:
EF/AC = ED/AB
ED = AB·(EF/AC) = 4z(x/(8x)) = (4/8)z = z/2
The mnemonic SOH CAH TOA reminds you that the tangent relationship is ...
Tan = Opposite/Adjacent
tan(F) = ED/DF = (z/2)/y
tan(F) = z/(2y)
_____
* Actually, you need to do this in reverse order: first you need to determine if you have all the necessary information to answer the question. You don't.
You need to know the length of side ED in terms of z. You notice that the corresponding side in similar triangle ABC has its length marked as a function of z, so all you need to find ED is the scale factor between the two triangles.
Since both hypotenuses are marked in terms of x, the scale factor is easily found.

The horse traveled 439.6 feet after walking around the track 5 times
Solution:
Given that, horse walks around a circular track while its trainer stands in the center
The trainer is 14 feet from the horse at all times
Therefore, radius of circular track = 14 feet
The circumference of circle is the distance traveled by horse for 1 lap
The circumference of circle is given as:
[tex]C = 2 \pi r[/tex]
Where, "r" is the radius and [tex]\pi[/tex] is a constant equal to 3.14
[tex]C = 2 \times 3.14 \times 14\\\\C = 87.92[/tex]
Thus the distance traveled by horse for one time in circular track is 87.92 feet
About how far had the horse traveled after walking around the track 5 times?
Multiply the circumference by 5
[tex]distance = 5 \times 87.92\\\\distance = 439.6[/tex]
Thus the horse traveled 439.6 feet after walking around the track 5 times
