The tables that represent a function are tables B, C, and D.
Functions and tablesFor a table to represent a function, each value of the domain must have a unique value in the co-domain.This means that the x-variables must not have similar values. From the given tables, you can see that table A has 2 being repeated compared to others.
Hence the tables that represent a function are tables B, C, and D.

x = two-thirds, four-fifths
c.
x = three-halves, five-fourths
b.
x = negative two-thirds, negative four-fifths
d.
x = negative three-halves, negative four-fifths
Please select the best answer from the choices provided
Answers
The solution to the quadratic equation is x = negative two-thirds, negative four-fifths. Option C
How to determine the quadratic solutionFrom the information given, we have that;
15 x squared + 22 x = negative 8
This is represented mathematically as;
15x² + 22x = -8
Equate the quadratic expression to zero, we get;
15x² + 22x + 8 = 0
Find the pair factors of the product of 15 and 8 that sum up to 22. The value is 120
Now, substitute the value into the formula
15x² + 12x + 10x + 8 = 0
Evaluate the equation in pairs, we have;
(15x² + 12x) + (10x + 8) = 0
Factor the common terms
3x(5x + 4) + 2( 5x + 4)= 0
Then, we have;
(3x + 2) (5x + 4) = 0
If 3x + 2 = 0
x = -2/3
If 5x + 4 = 0
x = -4/5
Hence, the values are -2/3 and -4/5

1. csc2(x) - 2csc(x)cot(x) + cot2(x) = tan2 (x/2)
2. [cos cos (x) cos(y)] [tan tan (x) + tan tan(y)] = sin(x + y)
Answers
Answer:
here you go!
Step-by-step explanation:
Working with the left hand side
( 1 + cos x ) + ( 1 − cos x ) ( 1 − cos x ) ( 1 + cos x 1 + cos x + 1 − cos x 1 − cos 2 x 2 sin 2 x 2 csc 2 x
which is equal to the right hand side
By using trigonometric identities both the questions are proved LHS = RHS. 1. csc2(x) - 2csc(x)cot(x) + cot2(x) = tan2 (x/2). 2. [cos (x) cos(y)] [tan tan (x) + tan(y)] = sin(x + y).
What are trigonometric identities?
Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
1. csc2(x) - 2csc(x)cot(x) + cot2(x) = tan2 (x/2)
Proof; LHS
[tex]csc^2(x) - 2csc(x)cot(x) + cot^2(x)\\\\(cscx - cot x)^2\\\\(\dfrac{1}{sin x} - \dfrac{cosx}{sin x} )^2\\\\\\(\dfrac{1-cosx}{sin x})^2\\ \\(tan)^2\dfrac{x}{2}\\[/tex]
Thus, LHS = RHS
2. [cos cos (x) cos(y)] [tan tan (x) + tan tan(y)] = sin(x + y)
Proof; LHS
[tex][cos (x) cos(y)] [tan (x) + tan(y)]\\\\ (cos (x) cos(y)) (\dfrac{sinx}{cos x} + \dfrac{siny}{cos y} )\\\\sin x \; cos y +sin y\; cos x\\\\sin (x+ y)[/tex]
Thus, LHS = RHS

The common difference of an arithmetic sequence is -5. If a12 is 22, what is a1?
Answers
Answer:
77.
Step-by-step explanation:
an = a1 + (n-1)d where d is the common difference.
a12 = a1 + 11d
22 = a1 +11(-5)
22 = a1 - 55
a1 = 22 + 55
a1 = 77.
The first term of the arithmetic series can be obtained using the relation, A12 = a1 + 11d ; Hence, the first term is 77
To obtain the nth term of an arithmetic series ; use the relation :
An = a1 + (n-1)d a1 = first term d = - 5 A12 = 22The 12th term can be defined as :
A12 = a1 + 11d22 = a1 + 11(-5)
22 = a1 - 55
22 + 55 = a1
a1 = 77
Therefore, the first term of the arithmetic series is 77

Answers
Answer:

Step-by-step explanation:
Answer:
Step-by-step explanation:
so first you have to subtract 64 dollars from your balance so $98-$64=$34.
Next you have to subtract $10.85 from your new balance so it would be $34-$10.85=$23.15
Last you have to divide 23.15 by 1.65 because you have to see how many cookies you can afford, so it would be 23.15 divided by 1.65 and the answer is 14. so you can afford 14 cookies

Step-by-step explanation:
Domain reffers to the set of the 1st elements, so the x values. In the image we see the ellipse go through both x and y axis but since the question is asking for domain and NOT range (range meaning y values) we can conclude that we need the x values, those being -4 and 4.
