Your equation is just to multiply 480 by 3/4.
Easy way to do these quick.
480 (3/4) is the same as (480 * 3) / 4
480 / 4 = 120
By simplifying, you are left with just 120 * 3 in the numerator
120 * 3 = 360
There are 360 people on the plane.
If you need to check your answer:
360 / 480
Take away the zeros at the end by dividing both by 10
36 / 48
Divide both by 6
6 / 8
Now divide by 2
3 / 4
Answer:
First option
Step-by-step explanation:
Hi there!
The "constant additive rate of change" means a constant slope.
The slope is 
.
First of all, if the slope is constant, then we know immediately that it must be a linear function, a line. The change in <em>y</em> is forever the same according to the change in <em>x</em>. Knowing this, the second option is for-sure wrong (it's not a straight line).
Now, let's look at the first option. It is a linear function, which means it has a constant slope. However, we're given that the slope is 
. This means that for a line, whenever it travels 4 units to the right, it travels 1 unit <em>down </em>(it travels down whenever the slope is negative and up whenever the slope is positive).
This is the exact case for the first option. Look at the point (-2,2) on the line. When we move 4 units to the right of that point, The line would have moved 1 unit down. We would reach the point (2,1).
Therefore, the correct answer would be the first option.
I hope this helps!
Answer:
j^-1(x) = 1/2(x+5)
Step-by-step explanation:
1. Replace j(x) with y to make it easier
y = 2x - 5
2. Switch the places of x and y
x = 2y - 5
3. Solve for y
x + 5 = 2y
y = 1/2(x+5)
4. Replace y with j^-1(x)
j^-1(x) = 1/2(x+5)
has degree 3, so it takes the general form
It has a root 
of multiplicity 2, which means 
divides exactly, and it has a root of 
of multiplicity 1 so that 
also is a factor. So
Expanding this gives
The 
-intercept occurs for 
, for which we have
Then
So we have
It about 30,000 add one thousand every minute
