Answer:
x = 80, y = 100
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 7 , then
sum = 180° × 5 = 900°
Sum the interior angles and equate to 900
y + 135 + 140 + 150 + 120 + 135 + 120 = 900, that is
y + 800 = 900 ( subtract 800 from both sides )
y = 100
x and y are adjacent angles and are supplementary, that is sum to 180°
x + y = 180
x + 100 = 180 ( subtract 100 from both sides )
x = 80
Thus x = 80 and y = 100

Shelia buys flower bulbs from a catalog $2 each and $4 shipping charge for the whole order. She spends $20 on flower bulbs. The model can be used to describe x, the number of bulbs Shelia can order. Write an equation to determine the number of bulbs Shelia can order. How many bulbs did she order?
Answers
Answer:
8 bulbs
Step-by-step explanation:
Step one:
Given data
Shelia buys flower bulbs from a catalog for $2 each and $4 shipping charge for the whole order
we are told that the total money spent is $20
let the number of bulbs ordered be x, and the total money spent be y
the equation for the situation is
y=2x+4
for a total amount of $20, we want to find x
20=2x+4
20-4=2x
16=2x
divide both sides by 2
x= 16/2
x= 8 bulbs

Answer:
x = 11 , m∠2 = 31
Step-by-step explanation:
We know that m∠1 is equal to both 6x+8 and 74
Therefore, 6x+8 = 74
And 6x = 66
x = 11
To find m∠2, we just plug in the value of x that we got earlier
(7x-2) + m∠2 = 106
(77-2) + m∠2 = 106
m∠2 = 31

If 6 days ago was Wednesday, what day will it be 701 days from now?
A Wednesday
B Thursday
C Friday
D Saturday
E Sunday
show work!!
Answers
Answer:
Friday
Step-by-step explanation:
If 6 days ago was Wednesday, that means 6 days ago was Thursday. Every seven days, it will be Thursday again, so we can do 701/7 and see how many weeks fit equally. It is 100 weeks and 1 day. That means that Thursday would be in 100 weeks, or 700 days. Since there is one day left, it would be Friday. Friday is your answer.
The day after 701 days from today if, 6 days ago was Wednesday is Friday, so option C is correct.
What is division?One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components.
Given:
If 6 days ago was Wednesday,
If 6 days ago was Wednesday, then it will be Thursday today,
Calculate the day after 701 days as shown below,
The day = 701 / total days
As you can see, the Thursday will be repeated after 7 days,
Here, 1 will be the reminder, then one day after Thursday will be Friday.
Thus, after 701 days, it will be Friday.

Find the values of a and b such that x^2-2x+2=(x-a)^2+b
Answers
Answer:
a = 1, b = 1
Step-by-step explanation:
Expand the right side and compare the coefficients of like terms on both sides, that is
right side
(x - a)² + b ← expand factor using FOIL
= x² - 2ax + a² + b
Compare to left side x² - 2x + 2
Compare the coefficients of the x- term
- 2a = - 2 ( divide both sides by - 2 )
a = 1
Compare the constant terms
a² + b = 2 ( substitute a = 1 )
1² + b = 2
1 + b = 2 ( subtract 1 from both sides )
b = 1
Thus a = 1, b = 1
The straight line 2x + 3y = 7 meets the curve
xy + 10 = 0 at the points P and Q. Calculate the
gradient of the curve at P and at Q.
Answers
Step-by-step explanation:
xy + 10 = 0. => y = -10/x.
2x + 3y = 7. => 3y = -2x + 7, y = -2/3 x + 7/3.
When -10/x = -2/3 x + 7/3,
-10 = -2/3 x² + 7/3 x, 2/3 x² - 7/3 x - 10 = 0.
=> 2x² - 7x - 30 = 0
=> (2x + 5)(x - 6) = 0
=> x = -2.5 or x = 6.
dy/dx = d/dx [-10/x] = 10/x².
When x = -2.5, dy/dx = 10 / (-2.5)² = 1.6.
When x = 6, dy/dx = 10 / (6)² = 5/18.
Hence the gradients at the points are 1.6 and 5/18.

Answer:
if you are given two points, use the equation y2-y1 / x2-x1
if you are given a graph, use rise/run
Step-by-step explanation:
if you have two points, like (4,5) and (6,9), take the second numbers of both pairs (the ys) and subtract them from each other (usually 2nd y minus 1st y), so with these points I would do 9-5
then subtract the first numbers of both pairs (the xs) from each other too (just like the ys: 2nd x minus 1st x), so with these points I would do 6-4
now you have y=9-5 which is 4
and x=6-4 which is 2
now you put 4/2 and simplify it to get 2
so your slope with these points is 2
if you want to find slope on a graph, look at where the line crosses the x/y axis lines, the points where they meet, and look at the distance between each point that it crosses
to find the slope put the rise (vertical change in y between each point) over the run (horizontal change in x between each point) in a fraction like this
rise/run
simplify that and you have your slope
