Answer:

[tex]27x^2[/tex]

Step-by-step explanation:

1) First, "cancel out" the 3s. Remember, exponents are kind of like another way of saying, "multiply this number by itself this many times." Whatever the bigger number is is the number that you multiply by itself, and the smaller number at the top indicates how many times you have to do that.

Take [tex]3^4[/tex], for example. It's saying "multiply 3 by itself 4 times." Therefore, you can write it as (3)(3)(3)(3):

[tex]\frac{3^4x^4}{3x^2} \\= \frac{(3)(3)(3)(3)x^4}{(3)x^2} \\[/tex]

Now, simplify. For each 3 in the denominator, cross out a 3 in the numerator. So, cross out the single 3 in the denominator, and cross out one 3 in the numerator. Then, multiply the left over 3s. This gives us this:

[tex]\frac{(3)(3)(3)x^4}{x^2}[/tex]

[tex]= \frac{27x^4}{x^2} \\[/tex]

2) Do the same with the x's. Write them out, cancel them out, and then multiply the leftovers together:

[tex]\frac{27x^4}{x^2}\\= \frac{27(x)(x)(x)(x)}{(x)(x)}\\= 27 (x)(x)\\= 27x^2\\[/tex]

Therefore, [tex]27x^2[/tex] is the answer.

Answer:

y=4x because the y values are bigger than the x values by 4 times

Answer:

Y=4x

When x is 0, y is 0 so there's no y intercept

It goes up 4 every time

Answer:

Intercept form     [tex]\frac{x}{-5} + \frac{y}{-4} = 1[/tex]

The standard form of the equation of the line

   4 x + 5 y +20 =0

Step-by-step explanation:

Explanation

Given that x-intercept (a) = -5

and y-intercept (b) = -4

Intercept form

                 [tex]\frac{x}{a} + \frac{y}{b} = 1[/tex]

                [tex]\frac{x}{-5} + \frac{y}{-4} = 1[/tex]

          ⇒   [tex]\frac{4x+5y}{-20} = 1[/tex]

                4 x + 5 y = -20

Final answer:-

The standard form of the equation of the line

               4 x + 5 y +20 =0

Answer:

60

Step-by-step explanation:

Answer:

x = -(1 + 4i)

or x = -1+4i

Step-by-step explanation:

From what we have;

-(x + 1)^2 = 4

(x + 1)^2 = -4

x + 1 = √-4

x + 1 = -4i or 4i

x = -1 - 4i or -1 + 4i

Answer: f(x)=x

The question is not clear. Can you please attach the picture of the question?

Based on these observations, the following statements are true for the given function: f(0) = 3, f(1) = 4, and f(2) = 5.

Functions are mathematical entities that take an input, perform some operation on it, and produce an output.

They are often represented using function notation, such as f(x), where f is the name of the function and x is the input.

Using the given table and function f(x) = x + COF, we can make the following observations:

Thus, the statements that are true for the given function: f(0) = 3, f(1) = 4, and f(2) = 5.

Answer:

Terry's initial amount = £780

Step-by-step explanation:

Given that:

Ratio of Terry's money to Faye's money = 3 : 5

Let,

x be the amount of money.

Terry's amount = 3x

Faye's amount = 5x

Now,

3x + 220 = 5x - 300

220+300 = 5x - 3x

520 = 2x

2x = 520

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{520}{2}\\x=260[/tex]

Terry's initial amount = 3x = 3(260) = £780

Hence,

Terry's initial amount = £780

Answer:

Width = 696.

Length = 697.

Step-by-step explanation:

Let the width be x, then the length = x+1 feet.

Using the Pythagoras Theorem:

x^2 + (x + 1)^2 = 985^2

x^2 + x^2 + 2x + 1 = 985^2

2x^2 + 2x - 970224 = 0

Using the quadratic formula:

x = [-2 +/- √(2^2 - 4*2*-970224)] / (2*2)

x =   696, -697(we ignore the negative root).
