Answer:
9y(3y+2)
Step-by-step explanation:
<h2>
Hello!</h2>
The answer is:
The ball will hit the ground after
<h2>
Why?</h2>
Since we are given a quadratic function, we can calculate the roots (zeroes) using the quadratic formula. We must take into consideration that we are talking about time, it means that we should only consider positive values.
So,
We are given the function:
Where,
Then, substituting it into the quadratic equation, we have:
Since negative time does not exists, the ball will hit the ground after:
Have a nice day!
Answer:
x = 3
Step-by-step explanation:
3x + 3 = 6 + 6
3x + 3 = 12
3x = 12 - 3
3x = 9
x = 3
3 (3) + 3 = 6 + 6
9 + 3 = 12
12 = 12
Answer:
3 hours
Step-by-step explanation:
288 ÷ 96 km/h = 3 hours
as time = distance ÷ speed
Option a is more steeper
The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept form formula is used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis).
According to the slope intercept form of equation
y = mx + c
where m = slope of the line
c = y-intercept
the steeping of the graph is determined by the slope of the line on the graph. The more is the value of the slope the more steeper the graph will be of the given line.
In option a: m=3 whereas option b: m=1/2
So y=3x+7 is more steeper
