Answer:
A) x+5=x+3
B) x+5=5+x
Step-by-step explanation:
A) If an equation has no solutions then when it is algebraically solved it will be an untrue statement.
For example, x+5=x+3. To solve subtract x from both sides. This becomes 5=3, which is not a true statement. Therefore, there are no solutions.
B) If an equation has infinite solutions then when it is algebraically solved it will be a statement that is always true.
For example, x+5=5+x. To solve first subtract x from both sides. This equals 5=5, which is always true. Therefore, there are infinite solutions.

Suppose payments were made at the end of each month into an ordinary annuity earning interest at the rate of 2.5%/year compounded monthly. If the future value of the annuity after 10 years is $60,000, what was the size of each payment? (Round your answer to the nearest cent.) $
Answer:
Monthly payment= $440.71
Step-by-step explanation:
Giving the following information:
Mothly interest rate (i)= 0.025/12= 0.00208
Number of periods (n)= 12*10= 120 months
Future Value (FV)= $60,000
To calculate the monthly payment, we need to use the following formula:
Monthly payment= (FV*i) / [(1+i)^(n) - 1]
Monthly payment= (60,000*0.00208) / [(1.00208^120) - 1]
Monthly payment= $440.71

Dakota earned $11.25 in interest in Account A and $25.00 in interest in Account B after 15 months. If the simple interest rate is 3% for Account A and 5% for Account B, which account has the greater principal? Explain.
Which account has the greater principal? Select the correct answer below and fill in the answer boxes to complete your choice.
Answer:
Step-by-step explanation:
I=Prt
11.25=A(0.03)(15/12)
11.25=A(0.0375)
A=11.25/(0.0375)
A=$300
25=B(0.05)(15/12)
25=B(0.0625)
B=25/(0.0625)
B=$400
So account B has the greater principal.

If x increases by 7 in each row of a table of values, and the first differences are all equal to 45.5, then the rate of change is:
a) 6.5
b) 455/7
c) 7/455
d) 318.5
Answer:
b i think
Step-by-step explanation: dont yell just tell me if i got it wrong if i did srry
The rate of change when x increases and the first difference equal to 45.5 is 6.5. Then the correct option is A.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope is given as
[tex]\rm Slope = \dfrac{Rise \ or \ fall}{Run}[/tex]
If x increases by 7 in each row of a table of values and the first differences are all equal to 45.5. Then the rate of change will be given by the slope.
[tex]\rm \\Slope = \dfrac{45.5}{7} = 6.5[/tex]
The rate of change is 6.5.

A clothing company is interested in the relationship between the number of sales per month for its employees (y) and price. Based on the collected data, the least-squares regression line is ŷ = 9.74 + 4.89x, where x is the number of dollars by which price exceeds $25. Which of the following statements best describes the meaning of the slope of the least-squares regression line?
Question 3 options:
1)
For each increase in price of $1, the estimated number of sales per month increases by 4.89.
2)
For each increase in price of $1, the estimated number of sales per month increases by 9.74.
3)
For each increase of one sale per month, there is an estimated increase in price of $4.89.
4)
For each increase of one sale per month, there is an estimated increase in price of $9.74.
5)
The slope has no meaning because the units of measure for x and y are not the same.
Answer:
1) For each increase in price of $1, the estimated number of sales per month increases by 4.89
Step-by-step explanation:
Using linear function concepts, it is found that the statement that best describes the meaning of the slope of the least-squares regression line is:
1) For each increase in price of $1, the estimated number of sales per month increases by 4.89.Linear function:A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem, the equation is:
[tex]y = 9.74 + 4.89x[/tex]
The slope is of 4.89, which means that when x(number of dollars by which price exceeds $25) changes by 1, y(number of sales per month) increases by 4.89, hence option 1 is correct.

Answer:
Step-by-step explanation:
Remark
Let x by the multiplying factor to make up 190 m.
2x + 5x + 3x = 190

Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2
Answer:
-11/10 (fraction) or -1.1 (decimal)
Step-by-step explanation:
The slope formula is m=(y2-y1)/(x2-x1)
x1 = 7
x2 = -3
y1 = -7
y2 = 4
So, it’s: (4 - (-7))/(-3-7)
= (4+7)/(-3-7)
= (11)/(-10)
= -11/10 or -1.1

Supplementary angles add to 180
So, the angle supplementary to the angle of 112 degrees measures 68 degrees.
If these two lines are parallel, the angles are the same.
So, the triangle has angle measures: 2x, 68, and 68.
2x+68+68=180

4) Find the missing term.
Sue has 4lbs 6oz of apples. Her younger brothers ate some and now she has 2lbs and 10oz how many lbs and oz of apples did they eat
Answer: 1 lbs 12 oz
Step-by-step explanation:
First and foremost, we should note that 16 ounces = 1 pound
Sue has 4lbs 6oz of apples. This in ounces will be:
= (4 × 16) + 6
= 64 + 6
= 70 ounces
Her younger brothers ate some and now she has 2lbs and 10oz. The ounces of apples left will be:
= (2 × 16) + 10
= 32 + 10
= 42 ounces
Therefore, the amount they ate will be:
= 70 ounces - 42 ounces
= 28 ounces
Since 16 ounces = 1 pounds
= 1 pounds 12 ounces
= 1 lbs 12 oz
