Answer:

The height of the area is (x - 3) ft.

Step-by-step explanation:

You can do this a few ways.  You could use long division to divide the area by the width, or you could just factor the area, which is guaranteed to have the width as a factor, leaving you with the height.

Let's go with factoring, as that's probably what this question is intended as:

[tex]= \frac{2x^2 - 9x + 9}{2x - 3} \\\\= \frac{2x^2 - 6x - 3x + 9}{2x - 3} \\\\= \frac{2x(x - 3) - 3(x - 3)}{2x - 3} \\\\= \frac{(2x - 3)(x - 3)}{2x - 3} \\\\= x - 3[/tex]

Answer:

£8

Step-by-step explanation:

A

Sam:Adam

2:5

3=£12

12÷3=4

1=4

4×2=8

sam=£8

It is asking for a convex nonagon, not a convex polygon. So in this case we are looking for a shape with 9 straight lines and 9 angles. Which means we can cross A out.

Now we need to look at which nonagon is a convex nonagon which means that we are looking for the shape having only interior angles measuring less than 180°. So this means that B and D can be crossed out.

Thus, the answer is C.

Step-by-step explanation:

x2-7x-34-10=0

x2-7x-44=0

(x-11)(x+4)=0

x= 11 or x= -4

Answer:

x = 11 or x = -4

Step-by-step explanation:

x^2 - 7x - 44 = 0

-11 + 4 = -7, -11 × 4 = -44

(x -11)(x + 4) = 0 or (x + 4)(x - 11) = 0 Both are same way: O

x = 11 or x = -4 would be the answer : )

Answer:

[tex] a = \dfrac{5}{18} [/tex]

[tex]b = -\dfrac{1}{18}[/tex]

Step-by-step explanation:

You need to rationalize the fraction.

[tex] \dfrac{1}{5 + \sqrt{7}} = a + b\sqrt{7} [/tex]

[tex] \dfrac{1}{5 + \sqrt{7}} \times \dfrac{5 - \sqrt{7}}{5 - \sqrt{7}} = a + b\sqrt{7} [/tex]

[tex] \dfrac{5 - \sqrt{7}}{25 - 7} = a + b\sqrt{7} [/tex]

[tex] \dfrac{5 - \sqrt{7}}{18} = a + b\sqrt{7} [/tex]

[tex] \dfrac{5}{18} - \dfrac{1}{18}\sqrt{7} = a + b\sqrt{7} [/tex]

[tex] a = \dfrac{5}{18} [/tex]

[tex]b = -\dfrac{1}{18}[/tex]

Answer:

yes , keiko is correct.

sin^(-1)x = -sin^1

Answer:

Keiko is wrong

Step-by-step explanation:

Keiko is incorrect

When n is positive, 1^n will always be 1

but........ (-1)^n will not always be -1

This is because there are parenthesis around -1

So n is even, then it will be 1 not -1

For example, n = 4

You will do -1 * -1 * -1 * -1 which is 1 not -1

but if n = 3

You will do -1 * -1 * -1 which is -1

Therefore, the second statement is incorrect resulting in Keiko being wrong

Answer:

b) [tex]f^-1(x)[/tex]= ∛(4x-24)

c)2

Step-by-step explanation:

these ones are inverse functions

change the f(x) for y and make x the subject

y= x³/4 +6

(y-6)x 4 = x³

∛(4y-24)= x

then put x back were y is

[tex]f^-1(x)[/tex]= ∛(4x-24)

and to do c just put in 8 where x is

∛(4(8)-24)= 2

Answer:

ur answer should be C. But I'm not really sure..

The table in which y is a linear function of x is; Choice C

According to the question;

The slope of a linear function is always constant.

Hence, By observing the table in Choice C;

Slope = (8-6)/(0-(-1)) = (10-8)/(1-0) = 2.

Hence, since slope of the function is constant, the required table is: Choice C.

Answer:

x = -3

Step-by-step explanation:

y = x + 8 and x + y = 2

Using substitution, we know that y = x + 8, so:

x + y = 2

x + (x + 8) = 2

2x + 8 = 2

2x = -6

x = -3

Then we solve for y:

x + y = 2

-3 + y = 2

y = 2 + 3

y = 5

Step-by-step explanation:

It's the first one. y can equal x as long as y doesn't equal x multiple times. We also know the last two are wrong because they're saying the same thing. A linear function is a straight line.
