12
You want to find an equivalent ratio with 2:3. As the question already gives you 8 where 2 used to be, you need to find out what change occurred to get from 2 to 8 (a multiplication of 4). To find the missing part of the ratio, multiply 4 with 3 to get 12.
<h3><u>
Answer:</u></h3>
Option: C is the correct answer.
c) the coefficient of x is positive
<h3><u>
Step-by-step explanation:</u></h3>
We know that graph of a line goes up and to the right when the coefficient of x is positive.
Since we know that when a line goes up and to the right this means that the line is increasing and hence we will get a positive slope of the line and we know that the slope intercept of a line is given as:

as m is positive this means that:
the coefficient of x is positive.
Hence, the correct answer is:
c) the coefficient of x is positive
Answer:
The length of the focal width of the parabola is 1.
Step-by-step explanation:
Suppose we have a parabola with the following equation:

The centre is at point
.
The length of the focal width is of |4p|.
In this question:
We want to place in the general format. So


Comparing, we have that 4p = 1. So the length of the focal width of the parabola is 1.
The answer is in the attached files, the first pic is for g(x) and the 2nd is f(x)
Answer:2
Step-by-step explanation: 2x2=4 therefore 4 is double 2
