What is the gradient of a line perpendicular to a line with a gradient of 5?

Answer:

[tex]2n + 4 = 3n - 6[/tex]

Step-by-step explanation:

In order to translate from words into equarion, we just have to know what means what.

Twice a number can be represented as [tex]2n[/tex], adding four to that is [tex]2n + 4[/tex].

3 times a number is [tex]3n[/tex], and 6 less than that is [tex]3n-6[/tex].

So these are equal to each other, we get [tex]2n + 4 = 3n - 6[/tex].

Hope this helped!

It's the 3rd answer choice

Answer:

This is a simple multiplication problem.

If 2 people, Amanda and her best friend divide evenly and each get $24.28, this means that the total is $24.28 x 2

$24.28 x 2

$48.56

I'm sorry if I misunderstood.

Good luck mate! :)

Answer:

1 + 2x = f(x) i believe

Step-by-step explanation:

Answer:

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

[tex]\frac{y-1}{2}[/tex] = x

Change y back into terms of x

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Answer:

He took 30 weeks to save $ 500

Step-by-step explanation:

Let 'x' be the number of weeks

Money deposited after each week = $ 15

Money deposited 'x' weeks = 15 * x = 15x

Opening balance in his account = $50

So, money that will be in his account after x weeks =  50 +15x

Total money in the bank = $500

50 + 15x = 500

       15 x = 500 - 50 { Subtract 50 from both sides}

        15x = 450   { Divide both sides by 15}

     15x/15 = 450/15

x =  30 weeks

Answer:

-15 = 7n + 8n

-15 = 15n

n = -1

plz brainlist me I need it

n = - 1

- 15 = 7n + 8n

15n = - 15

n = - 15 : 15

n = - 1

Answer:

y=8.4

Step-by-step explanation:

inverse proportion means y=k/x

k is the constant

y=12, x=7

k=xy ⇒7*12=84

y=84/x

y=84/10

y=8.4

As y varies inversely with x the value of y is 42/5 when x is 10.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, y varies inversely with x.

∴ y = k/x.

12 = k/7.

k = 84.

Now, x = 10.

∴ y = 84/10.

y = 42/5.

Answer:

$1.02 million

Step-by-step explanation:

Given

[tex]Amount = \$1.22\ million[/tex]

[tex]\%\ increase = 20\%[/tex]

Required

Determine the amount in 2007

Let the amount in 2007 be represented with x.

The relationship between these parameters is:

[tex]1.22\ million = x + 20\%\ of\ x[/tex]

[tex]1220000 = x + 20\% * x[/tex]

[tex]1220000 = x + 0.20* x[/tex]

[tex]1220000 = x + 0.20x[/tex]

[tex]1220000 = 1.20x[/tex]

Divide both sides by 1.20

[tex]\frac{1220000}{1.20} = x[/tex]

[tex]1016666.67 = x[/tex]

[tex]x = 1016666.67[/tex]

Hence, they paid $1.02 million in 2007

Step-by-step explanation:The tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle containing that angle. Example: In the triangle shown, tan(A)=68 or 34 and tan(B)=86 or 43 .

Given two sides

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)

if leg b is unknown, then. b = √(c² - a²)

for hypotenuse c missing, the formula is. c = √(a² + b²)

Answer:

if y=4.then 6(r+4).

which is 6r+24.

and if it is equal to zero which is like this then it will be 6r+24=0.

which will be 6r=-24.

r= -24/6.

r= -4.

Answer:

C(t)=3000(1.002417)^12t+960t

if T=1 year then the saving will be : 4048.17

Step-by-step explanation:

3000 deposit amount, 2.9 compound monthly interest .  save 80 dollars  per month at home .

A=p(1+r)^t

A=3000(1+0.029/12)^12t

A=3000(1.002417)^12t dollars

for the amount saved at home=80*12t=960t dollars

C(t)=3000(1.002417)^12t+960t

if T=1 year then the saving will be :

C(t)=3000(1.002417)^12t+960t

For question 3, the equation could have also been 3x°= 90°. However, I used ∠ sum of △ since I didnt want to assume that ∠ABC is a right angle.

Likewise for Q4, the polygon looks like a trapezium which means that the 2 horizontal lines are parallel and one could conclude that (3x +3)° +(2x +2)°= 180° (int. ∠s). But since it wasn't clearly indicated that they are parallel, I used the sum of interior angles to find x instead.

Answer:

The product is usually smaller than the two numbers multiplied

Step-by-step explanation:

When we multiply two decimals less than one, it is a certainty that the result of the multiplication would be less than the two decimals that were multiplied. An example is the multiplication of the decimals below;

0.958 * 0.325

which equals 0.31135

We can see from the example above that the result of the multiplication of the two decimals that are less than one, results in a product that is less than the factors that were multiplied.

Answer:

Strips should be 1.5 ft wide.

Step-by-step explanation:

Given:

Width of 1st piece = 6 ft

Width of 2nd piece = 7.5 ft

To find:

To find the maximum width possible to make strips of equal size from both the pieces.

Solution:

This problem can be visualized as if we are given two numbers and we have to find the Highest common factor for both of them i.e. HCF of 6 and 7.5 will be our answer.

Let us try to factorize the given factors:

[tex]7.5 = 3 \times 2.5 = \underline {3 \times 0.5} \times 5[/tex]

[tex]6 = 3 \times 2 = \underline {3 \times 0.5 }\times 2[/tex]

The common factors are highlighted above as underlined.

Therefore, the answer is 3 [tex]\times[/tex] 0.5 = 1.5 ft
