Answer:
Step-by-step explanation:
Slope m is defined as m=(y2-y1)/(x2-x1) in this case
m=(218-155)/(22-15)=63/7=9
y=mx+b
y=9x+b, using point (15,155) we can solve for the y intercept b
155=9(15)+b
155=135+b, b=20 so the line is
y=9x+20
In thirty days there will be
y=9(30)+20=290 coins
Mr. Tyler buys 4 round-trip tickets from Ft. Lauderdale, Florida, to Toronto, Canada. The total cost is $2,156. How much does each ticket cost? Enter the correct answer in the box
Answer: $539
Step-by-step explanation:
From the question, we are informed that Mr Tyler bought 4 round-trip tickets from Florida to Canada and that the total cost is $2,156.
The cost of each ticket will then be:
= Total cost of the tickets / Number of tickets
= $2156 / 4
= $539
Therefore, each ticket cost $539

Explain your reasoning
B. What does the point (3,90) represent in the context of this situation?
C. Based on the graph, how many dollars will Mr. David earn if he works
10 hours? Show or explain how you got your answer.
D. Write an equation that could be used to find y, the number of dollars
Mr. David earns for working x hours.
Answer:
A. Proportional by $30
B. 3 represents the hours he works
90 represents the money he earned
C. $300
D. I don know, sorry
Step-by-step explanation:
The relationship is linear, the point (3, 90) represents in 3 hours he earns 90 dollars, in 10 hours, he earns 300 dollars, and the linear equation is y = 30x.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
This graph shows the relationship between x, the number of hours Mr. David works, and y, the number of dollars he earns.
A. Based on the graph, the relationship between x and y proportional is a linear relationship.
B. The point (3,90) represents in 3 hours he earns 90 dollars.
D. The linear equation will be
[tex]\begin{aligned} \rm y - 30 &= \rm \dfrac{90-30}{3-1} (x - 1)\\\\\rm y - 30 &= \rm 30x - 30\\\\\rm y &= \rm 30x \end{aligned}[/tex]
C. Based on the graph, the amount of money in dollars will Mr. David earn if he works 10 hours will be
y = 30x
y = 30 × 10
y = $300

What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000
Answer:
18.6%
Step-by-step explanation:
What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000
Percentage increase is calculated as:
Final value - Initial value/ Initial value × 100
Final value = 510000
Initial value = 430000
Percentage Increase =
510000 - 430000/430000 × 100
= 80000 / 430000 × 100
= 0.1860465116 × 100
= 18.604651163 %
Approximately = 18.6 %

Carolyn borrowed $38,500 to pay
for college. If the interest rate is
3.2%, how much total will she
have paid after 10 years?
Answer:
$50820
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.2%/100 = 0.032 per year,
then, solving our equation
I = 38500 × 0.032 × 10 = 12320
I = $ 12,320.00
The simple interest accumulated
on a principal of $ 38,500.00
at a rate of 3.2% per year
for 10 years is $ 12,320.00.
i need to know the answer to these two questions up at the top please
Answer:
x = 3
x = 4.5
Step-by-step explanation:
A) 2(5x - 3) = 24
5x - 3 = 12 (divide both sides by 2)
5x = 15 (add 3 to both sides)
x = 3 (divide both sides by 5)
B) 5(2x + 1) = 50
2x + 1 = 10 (divide both sides by 5)
2x = 9 (take 1 away from both sides)
x = 4.5 (divide each side by 2)

If using the method of completing the square to solve the quadratic equation x^2-5x-19=0x, which number would have to be added to "complete the square"?
Answer:
25/4 or 6.25
Step-by-step explanation:
Given that the general equation of a quadratic equation is given as
ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.
Hence given x^2-5x-19=0, to complete the square, we add
(-5/2)^2 to both sides following the illustration given.
This is 25/4 or 6.24

How can you write an equation of a line when you are given the slope and the y-intercept of the line? Explain
Answer:
The linear equation that represents each function is y=mx+b. While The m represent the slop so instead of writing you write the slope provided. Then multiply by the X + b which is your Y-intercept.
Here is an example,
The slope is 2/3 and the y intercept is 6, write a linear equation for this sequence.
y= (2/3). X +6

Which of the following equations would be parallel to the line x = 3?
1. y = 3x
2. y = 1
3. y = x
4. x = 5
Answer:
4. x = 5
Step-by-step explanation:
For two lines to be parallel they must have the same slope, but not be the same line. Both x=3 and x=5 both have slopes of 0, so they are parallel. Another way to tell is that x=3 is a vertical line; therefore, it will be parallel to any other vertical line, such as x=5.
