6/15 simplified is 3/5 so the ratio can be written as:
3 to 5
3:5
3/5
Answer:
2.8 oz of water to 5 cups of flour
Step-by-step explanation:
a). The y-intercept is the point where the graph touches the y-axis.
It's the value of ' y ' when x=0.
The y-intercept of this graph is 4,500 ft.
It's the jumper's altitude at time = zero minutes.
b). The slope of the line is
(change in ' y ') / (change in ' x ')
both over the same part of the graph.
Let's use the whole graph ... the whole slanted line.
' y ' changes from 4,500 ft to zero. The change is - 4,500 feet
' x ' changes from zero to 3 minutes. The change is 3 minutes
Slope = (- 4,500 ft) / (3 min) = - 1,500 ft/minute
According to the slope, the diver is descending (dropping, going down).
The rate of drop is 1,500 ft per minute. Same as 25 ft per second.
c). The x-intercept is the point where the graph touches the x-axis.
It's the value of ' x ' that makes ' y ' be zero.
On this graph, the x-intercept is 3 minutes.
It's the time when the diver reached the ground ... her altitude became zero.
Okay, this is a simplified version of how to solve this complicated equation.
First add like terms but in this equation is not very efficient when solving.
So subtract the -2x squared from both sides and the equation should like mine
x⁴ + 4x³ + 12x + 45 = x ² -2x ² + 6x + 9
So keep the left side of the equation the same, but change the right like this because your adding the x squared.
-x² + 6x + 9
Now go back to the whole equation
x⁴ + 4x³ + 12x + 45 = -x² + 6x + 9
You can’t do anything on the left side of the equation do the same process with the other numbers like this:
x⁴ + 4x³ + 12x = -x² + 6x + 9 -45
You subtract the 45 from each side and it’s negative on the other side because you subtracted it.
Now add the 9 and -45 = -36
Now the equation should look like this:
x⁴ + 4x³ + 12x = -x² + 6x -36
Subtract -12x from each side and the 12x on the left side of the equation is canceled out and is gone
The equation should look like this:
x⁴ + 4x³ + = -x² + 6x -36 -12x
Then add the 6x and -12x because they are like terms
So this is the final simplified version of the complex problem
x⁴ + 4x³ + = -x² + -36 -6x
You can’t add any other like terms to find the value of x because x and x² can’t be added together
