Answer:

y = -12x + 3

Step-by-step explanation:

The slope-intercept form of an equation can be written as y = mx + b where m is the slope and b is the y-intercept. We are given both values, so we can plug them into the equation to get:

y = mx + b

y = -12x + 3

take 1 finger and 1 more finger how much is it 2 ! ok so bye do good work !!!

Step-by-step explanation:

I can read your mind you know

just ask me how

and see the magic

think of any number,

add it by 3 then by 5 then by 1.

multiply it by two

divide it by two

subtract the first number you thought of from your current number

your answer will be 9

I'm I correct ?

Answer:

2 x 3 = 6 + 4 = 10 squared = 100

Step-by-step explanation:

The square of a number is the number that can be multiplied by itself to get that specific number, for example 10 x 10 = 100

Answer:

97,988.216

Step-by-step explanation:

So, we can find this by using the following formula:

First value(change)^time

We know that the orginal, or first value, is 120,000.

We know that the time interval for this is 8 years, which is our time value.

We know that the decrease in this price is 2.5%. However, this is not our change.

Our change is the 97.5% price that is left.

This makes sense, because you would get a super small price when you use 2.5% as change.

So to sum up what we have done so far:

First value - 120,000

Change - 100%-2.5% = 97.5%. In decimal form: 0.975

Time - 8

So lets plug these into:

[tex]First_.value(change)^t^i^m^e[/tex]

=

[tex]120,000(0.975)^8[/tex]

And remember your order of operations here.

We dont have any equations or expressions inside the parethese, so we can move on to what comes next - exponents.

We have the exponent 8, which is attached to the 0.975.

So in your calculator, take 0.975, and put it to the 8th power.

You should get 0.816651803662261962890625

Lets leave it like this, becuase 120,000 is a very large value, and rounding what you multiply could change what you get in the end.

Now  our equation looks like:

120,000(0.816651803662261962890625)

We have done parethese, exponents - now we have multiplication and division.

We do indeed have this, since 120,000(0.816651803662261962890625) could also be written as:

[tex]120,000*0.816651803662261962890625[/tex]

Now multiplying this you should get:

97,998.216439471435546875

This is where you can round your answer.

I do not know what exactly they want you to round to, so its safe to just round your answer to the hundreths place:

97,998.22

So this is the new price of the car!

Hope this helps!

oh I did a mistake earlier , pardon ^^"

Let price after 8 years be P.

Using the compound interest formula of shrinking principal :-

P = Pₒ( 1 - R/ 100) ᵀ

P = 120, 000 ( 1 - 2.5/ 100)ᵀ

P = 120, 000 { (100 - 2.5)/ 100}ᵀ

P = 120, 000{ 97. 5/ 100 }ᵀ

P = 120, 000 {0. 975 } ⁸

P = 120, 000 { 0. 8166}

P = 97,998.216 $

Since, P is is price after 8 years

The price of the car after 8 years will be 97, 998. 216 $

The nearest tenth, the total volume of the orange is approximately 33.5 cubic inches.

To find the volume of a sphere, we use the formula:

[tex]Volume = (4/3) \times \pi \times radius^3[/tex]

Given that the radius of the orange is 2 inches, we can substitute this value into the formula:

[tex]Volume = (4/3) \times 3.14 \times 2^3[/tex]

Simplifying this calculation:

[tex]Volume = (4/3) \times 3.14 \times 8[/tex]

Volume = 33.49333333..

Note: To calculate the volume of a three-dimensional object, you need to know the appropriate formula based on the shape of the object.

Answer:

a=14

b=9.9

Step-by-step explanation:

for a.....

sin 45 = opposite/hypotenuse

sin 45 = (7√2)/a

make a the subject of the formula....

a = (7√2)/sin 45

a = 14

for b.....

tan 45 = opposite/hypotenuse

tan 45 = (7√2)/b

make b the subject of the formula...

b = (7√2)/tan 45

b = 9.9

Answer:

             [tex]= \frac{54.6}{15.6}\\\\= \frac{54.6*10}{15.6*10}\\\\=\frac{546}{156}\\\\= 3.5[/tex]

Answer:

We would have saved $12.

Step-by-step explanation:

First off, we know that the original price is $40.

Since the ball is 30% off, we'll multiply $40 by 70% to find the price it's sold by after the discount. 70% in decimal form is 0.70, so we would multiply 40(0.70)

40(0.70) = 28

This means that after a 30% discount, the price of the soccer ball is $28.

To find how much we saved, we would subtract $28 from $40.

40-28 = $12

$12 is the amount of money you saved.

Answer:

parallel = same slope (-2x)

so it's y=-2x + b

let's find b by plugging in 1 for x and 3 for y (the coordinates)

3 = -2*1 + b

3 = -2 + b

5 = b

there you have it:

y = -2x +5

Answer:

Step-by-step explanation:

The phrase in the original question is:

....if they lost 12 games......

not

....if they lost board games......

Answer:

36 games won

Step-by-step explanation:

Given

[tex]\%Win = 75\%[/tex]

[tex]Lost = 12\ games[/tex]

Required

Number of games won

Give that: [tex]\%Win = 75\%[/tex]

The percentage loss is:

[tex]\%Loss = 100\% - \%Win[/tex]

So, we have:

[tex]\%Loss = 100\% - 75\%[/tex]

[tex]\%Loss = 25\%[/tex]

Calculate the number of games (n) using:

[tex]Lost = \%Loss * n[/tex]

[tex]12 = 25\% * n[/tex]

Make n the subject

[tex]n = \frac{12}{25\%}[/tex]

[tex]n = 48[/tex]

So, the games won is:

[tex]Win = n - Lost[/tex]

[tex]Win = 48 - 12[/tex]

[tex]Win = 36[/tex]

cotA + tanA

=1/ sinA * 1/ cosA

= cosecA *secA

=secAcosecA

[tex]\frac{cos^2A + sin^2A}{sinAcosA}[/tex]Answer:

Step-by-step explanation:

cotA + tanA = secAcosecA

LHS=cotA + tanA

=[tex]\frac{cosA}{sinA}[/tex] + [tex]\frac{sinA}{cosA}[/tex]

take lcm of the denominator

=[tex]\frac{cosA*cosA + sinA*sinA}{sinAcosA}[/tex](COS^2A + sin^2A =1)

=[tex]\frac{1}{sinAcosA}[/tex]

=1/sinA * 1/cosA

=cosecA*secA

=secAcosecA

therefore LHS=RHS

hence proved.
