Answer: y=3x-9
Step-by-step explanation: To solve this, you'd first have to substitute 5,6 into an equation (you know that slope in standard form is y=mx+b, where m is slope and b is figure 0, or the y intercept), you have an x and a y. Then solve.
y=mx+b (y=6, m=3, and x=5)
6=3(5)+b --- Substitute values
6=15+b --- Subtract 15 from both sides (solving for b)
6-15=-9
b=-9
Hope this helps; let me know if you need further elaboration, as this is kind of hard to grasp at first.

The ratio of the length of a rectangle to its width is 4 1/2 : 2 1/4. What is the unit rate of the length per width of the rectangle?
Answer:
The ratio simplifies fully to 2:1
=======================================================
Work Shown:
4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5
2 & 1/4 = 2 + 1/4 = 2 + 0.25 = 2.25
The original ratio is the same as 4.5 : 2.25
Divide both parts by 2.25 and you'll end up with 2:1
4.5/2.25 = 2
2.25/2.25 = 1
This means the length is twice as long compared to the width.
A $15,600 car depreciates 9% each year. Based on the depreciation model,
how many years will it take for the car to be worth less than $100?
Answer:
Step-by-step explanation:
Take away 9% of $15,600 = 14196
Take away 9% of $14196 = 12918.36
(and so on)
Until you get less than $100. Note that you may need to round up some numbers after the decimal point.

Answer:
Step-by-step explanation:
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. ... The formula for the area of a regular octagon is 4.828 s², where s is the length of any side.
The number of sheets of paper available for making notebook is 75,000. Each sheet makes 8 pages of a notebook. Each notebook contains 200 pages. How many notebooks can be made from the paper available?
Answer:
3000 notebooks
Step-by-step explanation:
75000 sheets
each sheet has 8 pages
each notebook has 200 pages so,
75000x8=600000
600000/200=3000
Answer:
total number of sheet 75000
each sheet contain 8 page
page required to make not work is 200 pages
so 200 /8 = 25 to make a notebook 25 sheet is required
now, 75000/25 =3000
so, the number of notebook made from total number of sheet available is 3000

Use trigonometric ratios to solve each right triangle. Find the length os AC
Step-by-step explanation:
Hey there!
Given;
The measure of angle B is 45°.
And AB = 14.
Taking refrence angle as B, we get;
AC = perpendicular
AB = hypotenuse
Using ratio of sin,
[tex] \sin(45°) = \frac{p}{h} [/tex]
Put all values.
[tex] \sin(45°) = \frac{ac}{14} [/tex]
Simplify it to get answer.
[tex] \frac{1}{ \sqrt{2} } = \frac{AC}{14} [/tex]
[tex] \sqrt{2} AC = 14[/tex]
[tex]AC = \frac{14}{ \sqrt{2} } [/tex]
[tex]AC= \frac{14 \times \sqrt{2} }{ \sqrt{2} \times \sqrt{2} } [/tex]
[tex]AC = \frac{14 \sqrt{2} }{2} [/tex]
[tex]AC = 7\sqrt{2} [/tex]
Therefore the answer is option B.
Hope it helps...
solve the equation
-2x + 1 = -4x + 9
x=
Answer:
x = 4
Step-by-step explanation:
Step 1: Write equation
-2x + 1 = -4x + 9
Step 2: Solve for x
Add 4x to both sides: 2x + 1 = 9Subtract 1 on both sides: 2x = 8Divide both sides by 2: x = 4Step 3: Check
Plug in x to verify it's a solution.
-2(4) + 1 = -4(4) + 9

G(x)= -8x-3, evaluate g(x)+g(2)
Answer:
-8x - 22
Step-by-step explanation:
Step 1: Define
g(x) = -8x - 3
g(2) is x = 2
Step 2: Find g(2)
g(2) = -8(2) - 3
g(2) = -16 - 3
g(2) = -19
Step 3: Find g(x) + g(2)
-8x - 3 + -19
-8x - 3 - 19
-8x - 22

Dude this is Pythragorean Theorem =)).
You may have missed this part of your lesson. It's ok and also not ok at the same time beacause pythagorean theorem is a meme.
Ok I'll explain once =)).
Thousands of years ago, a mathematician named Pythagore found out that if we have 3 squares, with one square's area equals to the sum of two other squares, then when we put the sides of the squares together to form a triangle , it'll always be a right triangle ( a triangle with one of its angle is 90°). A square area is measured by the length of its side multipled by itself. So he came up with the statement : In a right triangle, the length of the hypotenuse( the side that does not connect to the right angle) is equalled to the sum of squared other sides.
EG.
In this triangle, the right angle is ^ACB. If length of BC is a, length of AB is c, length of BC is a
A
I We have a formula :
I \ a^2 + b^2 = c^2
I \
I \
I b \ c
I \
I \
I______\
C a B
So now you can use pythagorean theorem to show off =)).

If two coins are tossed together, then the chance for falling with heads up is 1/2. The chance for tails is also 1/2. Therefore, the chance that both coins will land on heads is _1/4___. The chance for the first coin to fall on tails and the second on heads is also ___1/4____. However, one head and one tail can be obtained if the first coin to fall on heads and the second on tails. There, the total probability of obtaining a head on one coin and a tail on the other is ___1/2___. The chance for both coins to land on tails is __1/4____. In summary, two coins tossed together are expected to land on heads _1/4_ of the time; one head and one tail __1/2___ of the time; two tails __1/4___ of the time. Stated as a ratio instead of fractions, the expected result is _____4:4 or just_____.
Answer:
Stated as a ratio instead of fractions, the expected result is _____4:4 or just_____.
1
Step-by-step explanation:
In this particular case, the result of the two coins tossed together landing on heads 1/4 of the time; one head and one tail 1/2 of the time; and two tails 1/4 of the time is equal to 1.
This is because 1/4 + 1/2 + 1/4 = 1. It is the sum of all probabilities in the set or distribution. This sum is always equal to 1. Therefore, the sum of a probability distribution is the collection of the probabilities that define the chance of the various outcomes of an event or experiment.

06. A shop sells 200 chocolate, vanilla and strawberry ice creams in a day. Forty-two of
the loe creams sold are vanilla, and a quarter are strawberry. What percentage are
chocolate?
[2mks] show full working out
Answer:
If 200 is four qoaters, then 1 quater is 200/4 is 50. so 50 ice creams is strawberry. One quater in procantage is 25%.
after that you count how many ice crams are vanilia
[tex]\frac{42}{200}[/tex] after you divide it you get 0.21 which is 21%
After you just deduct 25+21 from 100
you get
100-46=54
the answer is 54%

Answer:
i think 5280÷28 is the correct answer
Answer: OMG The first person who answered was rude anyway this is how you would answer, you can round the you can round the total cost to get a $6000 estimate, which you will divide by 30 which is your rounded number estimate for the number of windows in the house.
The cost of each window is about $208.00. To solve this you divide $5820 by 28 round up to the nearest whole dollar.

Last month, Luke spent $1,300 on his mortgage (home loan payment), $320 for food, $280 on entertainment, $275 for his car
payment, $60 on car insurance, and $75 on clothing. What was the difference for the month between his fixed expenses and
variable expenses?
A)
$1035
B)
$1240
C)$960
D)
$900
Answer:
The difference between the two categories is 960.
The fixed expenses are: mortgage, car and insurance
1300 + 275 + 60 = 1635
The variable expenses are: food, entertainment, clothing
320 + 280 + 75 = 675
Subtracting those gives a value of 960.
