We have to graph the inequality:
\(y\ge-2x-4\)The first step is to graph the boundary line y = -2x - 4.
It has a y-intercept y(0) = -4.
We also can check that the x-intercept is x = -2.
With the two intercepts (or any other two points) we can graph the line.
This line will be graphed as a full line. This is because the line is included as part of the solution.
Now, because of the sign ">", the solution region includes all the values of y above the boundary line.
Then, we can graph the inequality as:

Sry all the answers couldn’t fit in the question but I’m putting the rest of the answers r on another question I made
Answers
Answer:
Graph is attached
6.5 feet
Step-by-step explanation:
The function is
\(h=-16t^2+25t+5\)
We need to find the height of the ball when the ball has been in the air for 1.5 seconds.
So, \(t=1.5\)
\(h=-16\times 1.5^2+25\times 1.5+5\\\Rightarrow h=6.5\ \text{feet}\)
The ball is \(6.5\ \text{feet}\) from the ground when the ball has been in the air for 1.5 seconds.
The graph denotes the path of the ball.

What is a scalene obtuse angle triangle?
A triangle called a scalene triangle has three sides that are all different lengths. In other words, a scalene triangle has three different angles and no two of its sides have the same length.
A triangle with one obtuse angle is referred to as an obtuse triangle. Any angle that is greater than 90 degrees but less than 180 degrees is referred to as an obtuse angle.

All edges of a cube are expanding at a rate of 2 centimeters per second.
(a) How fast is the volume changing when each edge is 3 cm? All edges of a cube are expanding at a rate of 2 cm/s.
(b) How fast is the volume changing when each edge is 13 cm(s)?
Answers
Therefore, the volume is changing at a rate of 54 cm3/s when each edge is 3 cm and at a rate of 1014 cm3/s when each edge is 13 cm.
The volume of a cube is given by the formula V = e3, where V is the volume and e is the length of each edge. Therefore, the rate of change of the volume with respect to the edge length is given by the derivative of the volume with respect to the edge length:
dV/de = 3e2
Since the edges are expanding at a rate of 2 cm/s, we can use the chain rule to find the rate of change of the volume with respect to time:
dV/dt = dV/de × de/dt = 3e2 × 2 = 6e2
(a) When each edge is 3 cm, the rate of change of the volume is:
dV/dt = 6(3)2 = 6(9) = 54 cm3/s
(b) When each edge is 13 cm, the rate of change of the volume is:
dV/dt = 6(13)2 = 6(169) = 1014 cm3/s
Therefore, the volume is changing at a rate of 54 cm3/s when each edge is 3 cm and at a rate of 1014 cm3/s when each edge is 13 cm.

We have:

A special 8-sided die is marked with the numbers 1 to 8. It is rolled 20 times with these outcomes.
3, 4, 5, 2, 7, 1, 3, 7, 2, 6, 2, 1, 7, 3, 6, 1, 8, 3, 5, 6
The experimental probability of rolling an odd number is _%, which is _% more than the theoretical probability.
Solution:
The possible outcomes of rolling an 8-sided die are:
S = {1, 2, 3, 4, 5, 6, 7, 8}
The odd numbers are:
Odd = {1, 3, 5, 7} = 4 outcomes
The theoretical probability of rolling an odd number is:
\(P_{T}(\text{Odd})=\farc{4}{8}=\frac{1}{2}=50\%\)
Now from the given 20 outcomes the odd values are:
Odd = {3, 5, 7, 1, 3, 7, 1, 7, 3, 1, 3, 5} = 12 outcomes
Compute the experimental probability of rolling an odd number as follows:
\(P_{E}(\text{Odd})=\frac{12}{20}=\frac{3}{5}=60\%\)
Thus, the experimental probability of rolling an odd number is 60%, which is 10% more than the theoretical probability.

There are a total of 27 steps on the staircase.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Let x be the total number of steps in the staircase.
Larry climbs exactly 2/3 of the stairs.
Number of steps Larry climbed = 2x/3
She goes back exactly 1/2 of the way to the bottom.
Number of steps returned = (2x/3) (1/2) = 2x/6 = x/3
She is at x/3 steps from the bottom.
From that spot, she climbs exactly 2/3 of the way to the top.
Remaining steps to the top = x - x/3 = 2x/3
Number of steps Larry climbed = 2/3 of the way to the top = (2/3)(2x/3) = 4x/9
So we get,
x/3 + 4x/9 + 6 = x
x - x/3 - 4x/9 = 6
x - 7x/9 = 6
2x/9 = 6
2x = 54
x = 27
Hence there are 27 steps in the staircase.

What does "inverse connection" actually mean?There is an inverse relationship between two parameters when they are connected, where the value of one parameter tends to decrease as the value of the other parameter increases. It's often described as a "bad friendship" in conversation.
According to the information:z * W is equal to 1.
The statement indicates that the constant's value is 2/3, so:
z * w = 2/3
The result of solving for any of the variables is:
either w = (2/3) / z or z = (2/3) / w
The following values fit that relation:
z w = (2/3) / z
