Answer:
i want to say 7x is the answer
Step-by-step explanation:
because if you add 5x to 9 = to 14 the -7 = to 7x
Consider the inequality x> 7.
Answer:
x is greater than 7, so x can be 8 or more.
Answer:
if x is greater than seven it would be 8 or more can't be 7 because its not >

What is the equation of a line with slope 4 and passes through point (4,2)?
Answer:
y = 4x - 14
Step-by-step explanation:
Use point-slope form and substitute the values.
y - 2 = 4(x - 4)
y - 2 = 4x - 16
y = 4x - 14

Jaylen used the seat number for each of the 6,500 fans' seats in the stands at a college football game and put the numbers in a computer program. He randomly chose 200 numbers and found that 36 of those people had also purchased a parking voucher. Estimate the number of fans in the stands at a sold-out football game that purchased a parking voucher. Explain.
Answer:
1170 seats
Step-by-step explanation:
Given
[tex]Seats = 6500[/tex]
From the computer program, we have:
[tex]Sample = 200[/tex]
[tex]Voucher = 36[/tex]
First, we calculate the proportion (p) of those that bought the voucher
[tex]Proportion = \frac{Voucher}{Sample}[/tex]
[tex]p = \frac{36}{200}[/tex]
[tex]p = 0.18[/tex]
Using the larger population (i.e. 6500 seats), the esitimate of people that have bought the voucher is then calculated as:
[tex]Estimate= Proportion * Seats[/tex]
[tex]Estimate= 0.18 * 6500[/tex]
[tex]Estimate= 1170[/tex]

If it's hard to see the answers are Pythagorean Theorem, rearrange the previous statement, Pythagorean Theorem, and Expand (b-x)2
Answer:
1) a2 = h2 + x2
✔ Pythagorean theorem
2) h2 = a2 - x2
✔ Rearrange the previous statement
3) c2 = h2 + (b-x)2
✔ Pythagorean theorem
4) c2 = h2 + b2 -2bx + x2
✔ Expand (b – x)2
Step-by-step explanation:
The Pythagorean Theorem could be represented mathematically as follows, Here, c represents the length of the hypotenuse (the longest side), or b or a are the lengths of the other 2 sides. From the equation, you can easily find the value of the 1 side if you have the values of the other 2
1) a2 = h2 + x2
Pythagorean theorem
2) h2 = a2 - x2
Rearrange the previous statement
3) c2 = h2 + (b-x)2
Pythagorean theorem
4) c2 = h2 + b2 -2bx + x2
Expand (b – x)2
What made Pythagoras think of the Pythagorean theorem?The number 1 : the number of reason.The number 2: the first even and female number, the number of opinion.The number 3: the first true male number, the number of harmony.The number 4: the number of justice or retribution.The number 5: marriage.The number 6: creationLearn more about Pythagorean theorem here https://brainly.com/question/14504604

Your fi nancial advisor recommends buying a 10-year bond with a face value of $1,000 and an annual coupon of $80. The current interest rate is 7 percent. What might you expect to pay for the bond (aside from b
Answer:
Bond Price= $1,070.24
Step-by-step explanation:
Giving the following information:
Cupon= $80
Number of periods= 10 years
Face value= $1,000
Interest rate= 7%
To calculate the price of the bond, we need to use the following formula:
Bond Price= cupon*{[1 - (1+i)^-n] / i} + [face value/(1+i)^n]
Bond Price= 80*{[1 - (1.07^-10)] / 0.07} + [1,000 / (1.07^10)]
Bond Price= 561.89 + 508.35
Bond Price= $1,070.24

Maxine spent 15 hours doing her homework last week. This week she spent 18 hours doing homework. She says that she spent 120% more time doing homework this week. Is she correct? Show your work to justify your decision.
Answer:
Yes
Explanation: 120 % = 1.2
If Maxine is correct, then she spent 1.2
times the hours she did homework than last week.
15 ⋅ 1.2 = 18.0 = 18
15 hours ⋅ 1.2 = 18.0 hours = 18 hours
This means that Maxine is correct.
