Answer:
y = 2x -2
Step-by-step explanation:
y = mx + b
We need the slope (m) and the y-intercept (b) to write the eqation.
The slope is the change in y over the change in x. We can see from the table that the y is changing by 2 as the x changes by 1
So the slope is 2/1 which is the same as 2
The slope (m) is 2.
The y-intercept is the place where the line crosses the y axis. It is at the point (0,b). When x is zero, what is y? If we follow the patter and move to the number before x is 1, we get x = 0. That means that we have to move back 2 units of the y's. That would be -2. So the y-intercept is the point (0,-2).
The y-intercept (b) is -2
y = 2x - 2
The actual sum is
0

Cyprian was allowed a discount of 11% for goods at sh 800 and a discount of 8.6% for worth 17000.What percentage discount was he allowed altogether
The percentage discount that Cyprian was allowed altogether was 8.21%.
What is the percentage discount?The percentage discount is a portion of the sales price that reduces the amount the purchaser or customer pays for their purchase.
Percentages are ratios of a value or variable compared to another or the whole matter.
We express Percentages as the quotients of the division operations multiplied by 100.
In this situation, the overall percentage discount is worked out step by step as follows:
Discount on goods worth Sh. 800 = 11%
= Sh. 88 (Sh. 800 x 11%)
Discount on goods worth Sh. 17,000 = 8.6%
= Sh. 1,462
The total value of goods = Sh. 17,800 (Sh. 800 + Sh. 17,000)
Percentage discount = 8.21% (Sh. 1,462/Sh. 17,800 x 100)
Thus, overall, the total discount based on the full value of goods Cyprian bought was 8.21%.

Multiply the previous term by 3 and subtract 4 The second term of the sequence is 5. Find the difference between the first and fourth terms of the sequence.
Answer:
72
Step-by-step explanation:
Given that the second term of the sequence is 5, and that we are to multiply the previous term by 3 and subtract 4, we can use that as a recursive formula to find the other terms of the sequence.
The first term of the sequence is:
5*3-4 = 11
The third term of the sequence is:
53-4=11
113-4=29
The fourth term of the sequence is:
53-4=11
113-4=29
29*3-4=83
The difference between the first and fourth terms of the sequence is:
83-11 = 72
So the difference between the first and fourth terms of the sequence is 72.

Find the values of k and m in the parallelogram?
Answer:
In order to find the values of k and m in a parallelogram, you would need to have additional information such as the coordinates of the points that make up the parallelogram and the formulas or equations that relate k and m to these points.
Here is one way to find the values of k and m in a parallelogram:
Label the four vertices of the parallelogram as A, B, C, and D with the opposite sides parallel to each other.
Find the slope of the line segment AB by using the formula (y2-y1)/(x2-x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.
Let the slope of AB be represented by k.
Find the slope of the line segment AD by using the same formula and let it be represented by m.
The values of k and m are now found.
Please note that, this method is only applicable if the Parallelogram is not degenerate i.e, it is not a rectangle or a line.
It is also important to keep in mind that different formulas or equations may be used depending on the specific context of the problem. It is also important to check that the slopes of opposite sides are equal.

As of 2018, the population of Turks and Caicos is 37,910 people. The Locust Grove football field is 120
yd. x 54 yd. If each person takes up 2 square feet, can the entire population of Turks and Caicos fit on
our football field?
Answer:
Step-by-step explanation:
No, the entire population of Turks and Caicos would not be able to fit on the football field. The total area of the football field is 6,480 square yards, which is equivalent to 13,728 square feet. Since each person takes up 2 square feet, this means that only 6,864 people could fit on the field. Therefore, the population of Turks and Caicos is more than double the amount of people that could fit on the football field.
4 hundreds is 10 times as much as 4 thousandths
No, 4 hundreds is not 10 times as much as 4 thousandths.
How to compare 4 hundreds and 4 thousandths?Numbers in the tens are numbers that are multiples of 10, such as 10, 20, 30, 40, etc.
4 hundreds is equal to 4 × 100 = 400.
4 thousandths is equal 4/1000 = 0.004
To compare their magnitudes, we can divide 0.4 by 0.004:
400 ÷ 0.004 = 100000
So 4 hundreds (400) is significantly larger than 4 thousandths (0.004).
Therefore, 4 hundreds is 100000 times as much as 4 thousandths.

How do you do this math problem involving csc? Can you do it on a ti-84 calculator?
Explanation:
The TI-84 calculator is fairly powerful and can handle things like this, but it's not needed to be honest. Any calculator will do.
"csc" is shorthand for "cosecant". It's the reciprocal of sine.
csc = 1/sin
Recall that
sin = opposite/hypotenuse
which means
csc = 1/sin = hypotenuse/opposite
What we'll need are the hypotenuse and opposite sides. Plot the points (0,0) and (-20,21). Draw a segment between them. This forms the hypotenuse of the right triangle shown below. This triangle is in the quadrant Q2 in the upper left corner. The hypotenuse 29 is found using the pythagorean theorem a^2+b^2 = c^2.
Use a = 20 and b = 21 to find c = 29.
According to that diagram, we can then say:
csc = hypotenuse/opposite = 29/21

Two alien spaceships start traveling toward each other from space stations that are 710,000 km apart. The first spaceship started an hour before the second spaceship and is traveling at 110,000 km/hr. In how many hours will the two spaceships meet if the second spaceship is traveling at 90,000 km/hr?
Answer:
They will meet after 4 hours from the departure------------------------
The distance is 710000 km and the first spaceship has travelled 110000 km in the first hour.
The remainder of the distance is reducing by:
110000 + 90000 = 200000 km an hourTime to travel before they meet:
(710000 - 110000)/200000 = 600000/200000 = 3 hoursAdd the first hour to this to get total travel time of 4 hours.

If Mrs. Sharma spends 17/25 parts of her earnings on her children's education, then she is spending (17/25) x 100 = 68% of her earnings on her children's education.
If the number of children is the same, she spends 68%/number of children on her daughter education.

Mr.Heritage invests $6000 total into two diffent bank accounts. One account pays 8% interest annually. The second par 10% interest antally. If he earns $560 in interest after one year, how much did he put in each account?
The amount invested in the two different bank accounts which has a simple interest of $ 560 is $ 2000 and $ 4000 respectively
What is Simple Interest?Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Given data ,
Let the simple interest be represented as SI
The value of SI = $ 560
Now , the total amount A = $ 6000
Let the first bank account be A
Let the second bank account be B
The amount invested in the bank account A be = P
The amount invested in the bank account B be = ( 6000 - P )
The rate of interest of bank account A = 8 %
The rate of interest of bank account B = 10 %
Now ,
The SI of bank account A = ( Principal Amount x Rate x Time Period ) / 100
Substituting the values in the equation , we get
The SI of bank account A = ( P x 8 x 1 ) / 100
The SI of bank account A = 8P/100
And ,
The SI of bank account A = ( Principal Amount x Rate x Time Period ) / 100
Substituting the values in the equation , we get
The SI of bank account A = [ ( 6000 - P ) x 10 x 1 ] / 100
The SI of bank account A = ( 60000 - 10P ) /100
And , the total SI = $ 560
So ,
8P/100 + ( 60000 - 10P ) /100 = 560
Multiply by 100 on both sides of the equation , we get
8P + 60000 - 10P = 56000
On simplifying the equation , we get
-2P = -4000
Divide by -2 on both sides of the equation , we get
P = $ 4000
So , the amount invested in bank account A = $ 4000
And , the amount invested in bank account B = $ 2000
Hence , the amount invested is $ 4000 and $ 2000 respectively
