9) X value range [-2/5,0] or [2,3]
b since I can't see a or c visablely) x>1
5) -5/3 ≤ x ≤ 2
6) The time interval by which the ball spends more than 1.5m above ground is about 0.263 <x< 1.166 seconds so about 1.397 seconds
9) To find the range of x value, you have to find the interception of these two solutions, and to do that, you have to find each of their solutions
To find the solution to 2x² ≥ 4x, you would first subtract 4x on both sides, resulting in 2x² - 4x ≥ 0. Then, you would factor to common terms, which are x and -2, the new inequality is 2x (x-2) ≥ 0. Then, you divide both 2x and 0 by 2. The new inequality is x (x-2) ≥ 0; you would then make everything ≥ 0. The solution is [- inf, 0] or [2, inf] for 5x² -13x -6 ≤ 0 you are basically doing the same thing for solving x which result in -2/5 ≤ x ≤ 3. With that said you find the interception of those 2 solutions which are [-2/5,0] and [2,3]. The first image should have a picture of the steps and a graph version of the work
b) To find the answer to x - 1/ (x+2) (x+3) > 0 you multiply both sides by (x+2) (x+3) you would then get x - 1 > 0. To islolate x you add 1 on both sides the final answer is x > 1
5) To solve 2x² + 3x + 1 ≤ 11x + 4x - x² you move 11x + 4x - x² on one side and simplify you would get 3x²
-x−10≤0. Then you split the second term into two terms which are 5x and -6x -> 3x² + 5 x - 6x - 10 ≤ 0 then you factor out the common terms in the terms you would then get (3x+5) (x-2) ≤ 0. Then you solve for x you would then get - 5/3 ≤ x ≤ 2. The new graph should show the solutions in graph form.
6) The first step is to create an inequality for the problem in this case it would be 7t - 4.9t > 1.5. At this point you move 1.5 on the left side to make 7t - 4.9t - 1.5 > 0 you would then multiply all terms on both sides by -1 to make -1.5 positive you would then get in standerd form 4.9t² -7t + 1.5 < 0. You would then factor with the quadratic formula after doing so you would get in its simplest form is (x - 1.166) (x - 0.263) < 0 then you would solve for x the time intervals that satisfy the scenario is about 0.263 ≤ x ≤ 1.166 then fine the difference between the solutions and that is about 1.937 seconds. The graph version is in the last picture.

Answers
The graph of saving function f(x) = 40 - 1.25x has been plotted with a slope of -1.25.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
Given the function,
f(x) = 40 - 1.25x
Now to plot it we need to put x = 0
f(0) = 40 so y-intercept is (0,40)
Now keep f(x) = 0
Then 0 = 40 - 1.25x
x = 40/1.25 = 32
So x-intercept is (32,0)
So plot a straight line using points (0,40) and (32,0).
Hence "The graph of saving function f(x) = 40 - 1.25x has been plotted".

This is the graph of y= x2 + 4x + 7 what is the range of this function?
Answers
The range of the function y = x^2 + 4x + 7 is y >= 3
How to determine the range of the function?The equation of the function is given as
y = x^2 + 4x + 7
Start by differentiating the above function
So, we have
y' = 2x + 4
Set the above equation to 0
So, we have
2x + 4 = 0
Divide through the equation by 2
So, we have
x + 2 = 0
Evaluate the like terms:
x = -2
Substitute x = -2 in y = x^2 + 4x + 7
y = (-2)^2 + 4(-2) + 7
Evaluate the expression
y = 3
The leading coefficient of the equation y = x^2 + 4x + 7 is positive
This means that the vertex is a minimum
So, the range is
y >= 3
Hence, the range of the function y = x^2 + 4x + 7 is y >= 3

In order to compare the lengths from the shortest to the longest, we need to convert all the fractions into decimals.

We have those lengths as:

To compare the lengths from the shortest to the longest, we need to first convert all the fractions into decimals.
So, we get that:
