Your answer is B. 2
This is because to rationalise the denominator, we need to multiply it by (3 - √7), so we get:
(3 + √7)(3 - √7)
3 × 3 = 9
3 × √7 = 3√7
3 × -√7 = -3√7
√7 × -√7 = -7
So all in all you get 9 - 7 which is 2.
I hope this helps!
A(b-c)
First substitute values
-8(12+4)=
Next, solve using ordering of PEMDAS
-8 (12+4)=
-8 (16)=12
Answer:
This type of transformation is a horizontal stretch.
<em></em>
Step-by-step explanation:
Given


Required
Determine the type of transformation
The first function can be expressed as:

While the second function is:

Solving f(0.5x), we have to substitute 0.5x for x in 

So:
The second function is:

<em>This type of transformation is a horizontal stretch.</em>

<em>i.e. f(x) stretched to g(x)</em>
Answer:
11/12
Step-by-step explanation:
6 7/12 - 5 2/3
=(6-5) + (7/12 - 2/3)
= 1 + 7/12 - 2*4 / 3*4
= 1 + 7/12 - 8/12
= 1 + 7-8 / 12
= 1 + -1/12
=11/12
Answer:where
