Step-by-step explanation:
[tex]3x + 9 = 3( - 5) + 9 \\ = - 15 + 9 \\ = - 6[/tex]
3x+9 is equals to -6 , not more than based on the inequality, but it is lesser than 21.
However, the solution must fulfil both criteria to be a solution to the inequality. Therefore x = -5 is not a solution to the inequality.
According to the graph on your graphing tool, what is true about f(x)= x^4-4x^2+x/-2x^4+18x^2
Answer:
I can't see the options, so i will find all the asymptotes.
We have the function:
[tex]f(x) = \frac{x^4 - 4*x^2 + x}{-2*x^4 + 18*x^2}[/tex]
First, we can graph this using a graphing tool, the graph can be seen below.
In the graph, we can see that when we approach x = 0 from the left, f(x) goes to negative infinity, while if we approach x = 0 from the right, f(x) goes to infinity.
This can be written as:
[tex]\lim_{x \to 0_-} f(x) = - \infty \\[/tex]
and:
[tex]\lim_{x \to 0_+} f(x) = + \infty \\[/tex]
A similar thing can be seen at x = 3, when we approach from the left f(x) goes to infinity, while if we approach from the left, f(x) goes to negative infinity.
Then:
[tex]\lim_{x \to 3_-} f(x) = \infty \\\\\lim_{x \to 3_+} f(x) = - \infty \\[/tex]
For x = -3 we can see that when we approach from the left, f(x) goes to negative infinity, while if we approach from the right, f(x) goes to infinity.
Then:
[tex]\lim_{x \to -3_-} f(x) = - \infty \\\\\lim_{x \to -3_+} f(x) = + \infty \\[/tex]
We also can see that as x goes to negative infinity or positive infinity, f(x) tends to -0.5
Then:
[tex]\lim_{x \to \infty} f(x) = -0.5 \\ \lim_{x \to -\infty} f(x) = -0.5[/tex]
So you need to check the options that match with some of the given tendencies.

What is the range of the function graphed below?
A. Y>-1
B X< -1
C X>-1
D Y< -1
LOOK AT THE GRAPH.
Answer:
Option A
Step-by-step explanation:
Range of a function is defined by the set of y-values (output values).
From the given graph,
Y-values of the exponential function given in the graph vary from y = -1 to y = ∞ (excluding both the points)
Therefore, Range of the given exponential function will be y > -1
Option A will be the correct option.

Which function is decreasing on the same interval as the function graphed here?
The function that is decreasing on the sale interval as the function graphed in the attached image is " F(x) = -x² + 4x -4.
What does it mean for a function to be decreasing?
When the y-value of a function is decreasing as the x-value goes up, that function is said to be a decreasing function.
That is when x1 < x2 then f(x1) ≥ f(x2)
What is the Proof of the above?Let F(x) = 4
Thus
f(4) = -(4)² + 4(4) -4
= 16 + 16 - 4
= 28
Now, let F(x) = 2
Thus
f(2) = -(2)² + 4(2) -4
= 4 + 8 - 4
= 8
Note that X1 = 4 and X2 = 2
Thus x1 < x2 then f(x1) ≥ f(x2).
Hence Option C is the decreasing function.

What is the unit rate for the ratio 4/7: 8/21?
Answer:
The unit rate is 1.5
Step-by-step explanation:
Given
[tex]Ratio = 4/7 : 8/21[/tex]
Required
Determine the unit rate
To do this, we need to express the ratio as:
[tex]Ratio = m : 1[/tex]
Where m is the unit rate
[tex]Ratio = 4/7 : 8/21[/tex]
Express as fraction
[tex]Ratio = \frac{4/7 }{ 8/21}[/tex]
Solve
[tex]Ratio = \frac{4}{7} * \frac{21}{8}[/tex]
[tex]Ratio = 1.5[/tex]
Express as ratio
[tex]Ratio = 1.5 : 1[/tex]
Hence, the unit rate is 1.5

Find the measure of A as indicates in the picture.
In case the picture blurs
Top angle = x + 63
Left angle = x + 96
Right angle = x + 149
Answer:
∠A = 58°
Step-by-step explanation:
all triangles contain 180°
180° - 149° = 31°
x + 63° + x + 96° + 31° = 180°
combine like terms:
2x + 190° = 180°
2x = -10°
x = -5°
∠A = -5° + 63° = 58°
A right cylinder has a height of 8 inches and a volume of 400 cubic inches.
Which measurement is closest to the radius, in inches, of the cylinder?
A. 4

Answer:
Step-by-step explanation:
its D because 400 divided by 8 is 50
[tex]\boldsymbol{4}[/tex] is closest to the radius, in inches, of the cylinder.
So, option A. is correct.
Volume of cylinderHeight of a cylinder [tex](h)=8[/tex] inches
Volume of a cylinder[tex]=400[/tex] cubic inches
Let [tex]r[/tex] denotes radius of a cylinder.
Volume of a cylinder [tex]=\pi r^2 h[/tex]
[tex]400=\frac{22}{7}r^2 (8)[/tex]

A spinner is divided into 4 equal sections numbered 1 to 4. The theoretical probability of the spinner stopping on 3 is 25%. Which of the following is most likely the number of 3's spun in 10,000 spins?
1,367
2,400
2,538
3,108
PUT SOLUTION AND STEPS PLS
To find how many times it will land on 3 in 10,00 spins you need to find 25% of 10,000 so 10,000 times .25 is the equation which is 2,500 so if I'm not mistaken the spinner should land on the third section 2,500/ times in 10,000 spins theoretically speaking, but if you have to find something close to it, its 2538 due to it being the closest.
Answer:
third one 2538
Step-by-step explanation:
it is the closest because 25% of 10,000 is 2500, the closest number to 2500 is 2538Jim bought some nice running shoes for $216. The sales
