Step-by-step explanation:
3) Sales tax rate = [tex]\frac{42.42}{499}*100[/tex]
= 8.50
= 9%
4) Rate of commission = [tex]\frac{1400}{28000}*100[/tex]
= 5 %
5) Reduction = [tex]\frac{30}{100}*5000[/tex]
=$ 1500
New price = 5000 - 1500
= $ 3500
A relation contains the ordered pairs (3, 8), (6, 10), (9, 12), and (a, b). For which values of a and is the relation a function?
. A. = 3 and b = 14
B. a = 6 and b = 12
C. = 9 and b = 9
D. a = ll and = 8
Answers
Answer:
value of a = 11
value of b = 8
Therefore, option D is correct.
Step-by-step explanation:
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Given the ordered pairs of a relation
(3, 8), (6, 10), (9, 12), and (a, b).
Now, we have to choose the ordered pair containing values of 'a' and 'b' such that there is no duplicated or repeated x-value in the domain of a relation.
It is clear that
WE CAN NOT chose a = 3 and b = 14 because then x = 3 would be repeated. Hence, option A is INCORRECT.
WE CAN NOT chose a = 6 and b = 12 because then x = 6 would be repeated. Hence, option B is INCORRECT.
WE CAN NOT chose a = 9 and b = 9 because then x = 9 would be repeated. Hence, option C is INCORRECT.
But, if we choose a = 11 and b = 8, then the relation would be a function because each input or x-value of the X set will have a unique y-value or output of the Y set.
i.e.
(3, 8), (6, 10), (9, 12), (a, b)
(3, 8), (6, 10), (9, 12), (11, 8)
Thus, the ordered pairs (3, 8), (6, 10), (9, 12), (11, 8) represent the function because each input or x-value of the X set will have a unique y-value or output of the Y set.
Hence,
value of a = 11
value of b = 8
Therefore, option D is correct.

a₁ = 2(1) - 5 = 2 - 5 = - 3
a₂ = 2(2) - 5 = 4 - 5 = - 1
a₃ = 2(3) - 5 = 6 - 5 = 1
The first 3 terms are - 3, - 1, 1

Which equation represents the line that is parallel to y = 3 and passes through (-2,-8)?
ОА. x= -2
OB. x= 3
OC. y=-8
OD. y= 3x-2
Answers
Answer:
its answer C. y=-8
Step-by-step explanation:
y=-8 passes through (-2, -8) and is parallel to y=3 because they're both horizontal
The equation represents the line that is parallel to y = 3 and passes through (-2,-8) is,
⇒ y = -8.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
We have given that,
The line that is parallel to y = 3 and passes through (-2,-8)
Now, We have to determine the parallel line passes through (-2,-8)
Slope of line y = 3 is, 0.
So, the slope of the line parallel to y = 3 is also 0.
Thus, the equation of line passes through (-2,-8) and parallel to y = 3 is,
y - (- 8) = 0(x - (-2))
y = - 8
Thus, The equation represents the line that is parallel to y = 3 and passes through (-2,-8) is y=-8.
