[tex]y = - 3x + b \\ 4 = - 3 \times ( - 2) + b \\ 4 = 6 + b \\ 4 - 6 = b \\ b = - 2[/tex]
Answer:
#1Substitute coordinates and sole for b:
y = -3x + b(x, y) = (-2, 4)4 = -3(-2) + b4 = 6 + bb = 4 - 6b = -2#2y = kxUse the point (2, 4) to find the coefficient k:
4 = 2k ⇒ k = 2Find the missing values:
x = -5 ⇒ y = 2(-5) = -10x = -1/2 ⇒ y = 2(-1/2) = -1x = 0 ⇒ y = 2(0) = 0y = 16 ⇒ x = 16/2 = 8y = 1/4 ⇒ x = (1/4)/2 = 1/8Related Questions
Use the table to add 287 + 56 vertically. The top row will be for regrouping (numbers that are "carried"). The bottom row will be
for your answer. The addends have already been filled in for you.
Answers
Answer:
regrouping: 1 1
first addend: 2 8 7
second addend: 5 6
sum: 3 4 3
Step-by-step explanation:
first: add the digits in the ones column
2 8 7
+ 5 6
13
because the answer is two digits, you leave the digit in the ones space in the answer, and move the digit in the tens space to the regrouping area above the tens column in the problem. it should look like this:
1
2 8 7
+ 5 6
3
then add the digits in the tens column. you also add the regrouped number.
1
2 8 7
+ 5 6
14 3
once again, the answer is two digits, so you repeat the same process, except since the digits are already in the tens place, you move the first digit above the hundreds place:
1 1
2 8 7
+ 5 6
4 3
add the hundreds column:
1 1
2 8 7
+ 5 6
3 4 3
this is you answer

300 - 15x < 200
Answers
Answer:
Joe is selling eggs on the market. He has a total of 300 eggs to sell. He is selling the eggs in batches of x amount of eggs. A customer wants to buy 15 batches of eggs. After the transaction, Joe's total amount of eggs is less than Macy's. Macy has a 200 eggs.
Real world scenarios can be represented by inequalities, and vice versa.
The inequality is given as:
[tex]300 - 15x < 200[/tex]
A possible scenario is as follows
How long will it take the number of people in a train station to be less than 200, if there are currently 300 people at the station, and 15 people leave the station every minute.
In the above scenario;
x represents the number of minutes
Since 15 people leave each minute, then 15x people would have left after x minutes.
The initial population is given as 300.
So, the current population after x minutes is 300 - 15x.
The current population is to be less than 200.
So, we have:
[tex]300 - 15x < 200[/tex]

Answers
Answer:
losing,losing,losing.
The lower bound for the 95% confidence interval for the percentage of voters that believe that the United States is losing the War is 33.8%.
What is the upper and lower bound?Upper and lower bounds are the maximum and minimum values that a number could have been before it was rounded. They can also be called limits of accuracy. The upper and lower bounds can be written using error intervals.
The lower bound for the 95% confidence interval can be calculated using the following formula:
Lower Bound = Percentage - (1.96 * Margin of Error)
In this case, the lower bound is calculated as:
Lower Bound = 38% - (1.96 * 2%) = 33.8%
Therefore, the lower bound for the 95% confidence interval for the percentage of voters that believe that the United States is losing the War is 33.8%.

Step-by-step explanation:
In the equation y=kx+1, k is the slope and 1 is the y-intercept.
To find the slope, use the formula k=y2-y1/x2-x1. To use this formula, you need two points. The first point, point M, is given to you. The second point can be the y-intercept, point (0, 1). Now, apply the formula to find the slope: k=3-1/1-0
k=2/1
k=2
We now have the equation y=2x+1.
The next step is to graph the line.
First, graph the y-intercept. Should look something like this: (star represents point. the point is on (0, 1).)

What is the equation? NO SPACES
X=30
Answers
< 90°, < 30°, and < 2x °, and that the sum of all angles must equal 180°, to setup the equation for x, we must create an equality statement:
< 90° + < 30° + < 2x° = 180°
Now, to isolate 2x:
We need to subtract < 90° and < 30° from both sides:
< 90° - < 90° + < 30° - < 30° + < 2x° = 180° - < 90° - < 30°
2x° = (180° - < 90° - < 30°)
Next, we must divide both sides by 2 to isolate x:
2x°/2 = (180° - < 90° - < 30°)/2
Therefore, the equation for x is:
x=(180-90-30)/2

Sum of two digits can be less than 20, therefore A = 1 is the only option for A, since AB ≤ 19.
Substitute A:
XYZ + ZYX = 1B11Then Y = 0 or Y = 5.
Y = 0 doesn't work as it leads to B = 1, which is a repeat of A.
So Y = 5.
Substitute Y:

Paulo has won the lottery. He is offered a series of payments of $10,000 per year for 10 years. What is the present value of these payments at an interest/discount rate of 6%
Answers
The present value of the payments is $73,600.87.
Present value of a cash flow is the value of the cash flow today. This is determined by adding the discounted cash flows of the cash flows together.
Discounted year 1 cash flow: 10,000 / (1.06) = 9,433.96
Discounted year 2 cash flow: 10,000 / (1.06)^2 = 8,899.96
Discounted year 3 cash flow: 10,000 / (1.06)^3 = 8,296.19
Discounted year 4 cash flow: 10,000 / (1.06)^4 = 7,920.94
Discounted year 5 cash flow: 10,000 / (1.06)^5 = 7,472.58
Discounted year 6 cash flow: 10,000 / (1.06)^6 = 7,049.61
Discounted year 7 cash flow: 10,000 / (1.06)^7 = 6,650.57
Discounted year 8 cash flow: 10,000 / (1.06)^8= 6,274.12
Discounted year 9 cash flow: 10,000 / (1.06)^9 = 5,918.98
Discounted year 10 cash flow: 10,000 / (1.06)^10 = 5,583.95
The sum of the discounted cash flows = $73,600.87
