Given:
The function is
[tex]y=\tan x[/tex]
To find:
The domain of the given function.
Solution:
We know that, domain is the set of x-values or input values.
We have,
[tex]y=\tan x[/tex]
[tex]y=\dfrac{\sin x}{\cos x}[/tex]
The functions sin x and cos x are defined for all real values of x. So, the function tan x is defined for all real values of x except those value for which cos x = 0.
So, domain is [tex]-\infty<x<\infty, x\neq \dfrac{\pi}{2}+n\pi[/tex].
Note: All options are incorrect.
Answer:
C
Step-by-step explanation:
all x≠pi/2+pi n

Is this the answer to this question i need help
Answer:
No, A is
Step-by-step explanation:
You can tell by plugging in the numbers. 0 - 3(0) < 1 as 0 < 1.
============================================================
Explanation:
Let's check if choice C is the answer or not
We will plug in x = -2 and y = 1 into the inequality to get
y - 3x < 1
1 - 3(-2) < 1
1 + 6 < 1
7 < 1
That's a false statement since 7 is not smaller than 1. This means the first inequality is false when (x,y) = (-2,1). So we can rule out choice C. Choices B and D are similar stories.
---------------
It turns out that choice A is the answer because
y - 3x < 1
0 - 3(0) < 1
0 - 0 < 1
0 < 1
Which is a true statement. So (x,y) = (0,0) is one solution to this inequality.
I'll let you check the other answer choices. You should find them to be false

Answer:
9/26
Step-by-step explanation:
Word : CONFIDENCE
Consonants in word : C, N, F, D, N, C = 6
Total alphabets = 10
Probability =required outcome /Total possible outcomes
Probability (consonants) = 6 /10 = 3/5
Number of red catds in deck = 26
Number of aces in a card deck = 4
Total number of cards = 52
P(red) or P(ace)
(4/52) + (26/52) = (4 + 26) / 52 = 30 / 52 = 15 / 26
P(getting a consonant, then a red card or ace)
(3 /5) * (15/26) = (3 * 15) / (26 *5) = 45/130 = 9/26

Plz, help I have no clue how to solve this.
Answer: Create equations. Top length=Bottom length
Left side = right side.
Combine like terms and rewrite the equations.
Use the new equations to create a system of equations to solve for x and y.
Once you have x and y, you can substitute those in the expressions for the lengths of the parallelogram.
You should end up with top and bottom lengths of 10. The sides are 9.
Step-by-step explanation:
3x-5 = 18 -2y . Rewrite as 3x + 2y = 23
x+4 = 21 -3y Rewrite as x + 3y = 17
The system of equations is
3x + 2y = 23 and x + 3y = 17 . To solve by substitution, multiply the second equation by -3 It becomes -3x-9y= -51 Add the equations so the x terms cancel. Solve for y
3x + 2y = 23
-3x - 9y = -51
0 -7y = - 28 Divide both sides by -7. y = 4
Substitute 4 for y, solve for x
x + 3(4) = 17
x + 12 = 17 . Subtract 12 from both sides x = 5
Substitute the values of x and y in the expressions
Top: 3x-5 is 3(5) -5 becomes 10
Bottom: 18 -2y is 18 - 2(4) becomes 10
Left: x +4 is (5) + 4 becomes 9
Right: 21 - 3y is 12 -3(4) becomes 9

Answer:

Step-by-step explanation:
We are asked to find a slope whilst given a graph.
To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.
So based on what I see, I can see (1, 1) and (2, 5).
The rise over run is as followed :
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
2 and 1 meaning the first and second number within the coordinate, so substitute :
[tex]\frac{5 - 1}{2 - 1}[/tex]
[tex]\frac{4}{1}[/tex]
Divide :
[tex]4[/tex]
4 is our slope.

-28 + 8 =
-20
An expression equivalent to 4(– 7) + 8 would be:
8 + 4(-7)
This is true because of the commutative property which states that a+b=b+a
Answer:
-20

It is very simple!
4x-7= -28
-28+8=20
Find the value
of 6y^2 - 24y - 51 when y=-2
Answer:
21
Step-by-step explanation:
6(y^2) - 24y -51 = 6 4 - 24y - 51
(6 4) - (24y) - 51 = 24 - -48 - 51
(24 - -48) - 51 = 72 - 51
72 - 51 = 21

What is the solution to the equation x÷8−6=3?
A. x=1
B. x=24
C. x=48
D. x=72
30 POINTS TO THE RIGHT ANSWER AND BEST EXPLANTION.
Answer: D. x=72
Step-by-step explanation:
With the equation x/8-6=3 we can start solving by first moving the "-6"
x/8-6(+6)=3(+6)
x/8=9 <-- Rewrite equation after adding "6" to both sides
x/8(*8)=9(*8) <--- Multiply both sides by 8
x=72 <-- After multiplying, solution is found
chris worked 3 1/2 hours at his uncles farm. He was paid 8$ for every 1/4 hour he worked. How much money did chris make
Answer:
$112
Step-by-step explanation:
So first figure out how much he makes an hour
8*4 is 32.
32*3 1/2 is $112
The amount that Chris will make will then be $112.
The first thing to do is to divide 3 1/2 by 1/4. This will be:
= 3 1/2 / 1/4
= 7/2 × 4/1
= 14
Now we'll then multiply 14 by $8. This will be:
= $8 × 14
= $112
The amount made will be $112.
