We want to list the steps involved in multiplying fractions;
Taking an example;
![\frac{2}{3}\times\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%5Ctimes%5Cfrac%7B3%7D%7B4%7D)
First steps are;
- Multiply the numerators together
- Multiply the Denominators together
![\begin{gathered} =\frac{2\times3}{3\times4} \\ =\frac{6}{12} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%3D%5Cfrac%7B2%5Ctimes3%7D%7B3%5Ctimes4%7D%20%5C%5C%20%3D%5Cfrac%7B6%7D%7B12%7D%20%5Cend%7Bgathered%7D)
Next is to;
Check to see if the product can be simplified;
![\frac{6}{12}=\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B12%7D%3D%5Cfrac%7B1%7D%7B2%7D)
So, we get the product to be;
-7/2
it’s in the equation already
it’s the m in the formula
it’s y=Mx+b
<span>By definition, lines are parallel if they have the same gradient (slope). Any horizontal line has a gradient of 0, so it is parallel to any other horizontal line</span>
Answer:
Step-by-step explanation:
( g ° f )(x) = ( x + 7 )² = x² + 14x + 49
20 + 3(x² + 14x + 49) = - 34
20 + 3x² + 42x + 147 = - 34
3x² + 42x + 201 = 0 ⇔ x² + 14x + 67 = 0
D = 196 - 268 = - 72 < 0
There is no any roots in set of real numbers.
The values of x in set of complex numbers are:

±
= - 7 ± 3√2 i
Answer:
- 7/8
Step-by-step explanation:
m = Δy/Δx = (10-3)/(2-10) = - 7/8
