the value of a baseball card can be represented by the equation y equals 3x + 39 where X represents the number of years that Robert has on the card and why represents the total value in dollars of the card what was the value of the card when Robert originally purchased it $3 $13 $36.39
Answer:
I need the values of either X or Y to solve this. I can solve for what X is though.
Step-by-step explanation:
A: X = -12
B: X =78
C: X = 12.13
I hope this helps you, but since both X and Y are unknown variables, you can't solve it, only simplify (which it already is.)

9514 1404 393
Answer:
A'(-4, 7) . . . . ending in quadrant 2
check switched coordinates for C', D'
Step-by-step explanation:
The transformations accomplished by rotations are ...
(x, y) ⇒ (-y, x) . . . . . 90° CCW or 270° CW
(x, y) ⇒ (y, -x) . . . . . 90° CW or 270° CCW
(x, y) ⇒ (-x, -y) . . . . 180° (either direction)
You notice that coordinates are switched and one is negated in each of these transformations. I assume that your line "Coordinates after the switch" is intended to lead you through that first step, then "New coordinates after rotation" is intended to be the same set of coordinates with the appropriate sign change.
__
1. A(7, 4) 90° CCW ⇒ (4, 7) ⇒ A'(-4, 7) . . . . ending in quadrant 2
2. B(-8, -1) 180° ⇒ B'(8, 2) . . . . ending in quadrant 1 (correct)
3. C(9, -5) 270° CW ⇒ (-5, 9)* ⇒ C'(5, 9) . . . . ending in quadrant 1
4. D(-6, -11) 90° CW ⇒ (-11, -6)* ⇒ D'(-11, 6) . . . . ending in quadrant 2
_____
* I would leave the original signs on the "coordinates after the switch". Here, you have dropped the signs. I don't know what you've been taught, but that's not how I would do it, as you can see above.
Find the cardinal number of set A = { a, b, c, d, e, f}
if answered correctly and answer is explained I will give brainliest!!!!
Answer:
What is the cardinal number of a set?
The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A) and read as ‘the number of elements of the set’.
For example:
(i) Set A = {2, 4, 5, 9, 15} has 5 elements.
Therefore, the cardinal number of set A = 5. So, it is denoted as n(A) = 5.
(ii) Set B = {w, x, y, z} has 4 elements.
Therefore, the cardinal number of set B = 4. So, it is denoted as n(B) = 4.
(iii) Set C = {Florida, New York, California} has 3 elements.
Therefore, the cardinal number of set C = 3. So, it is denoted as n(C) = 3.(iv) Set D = {3, 3, 5, 6, 7, 7, 9} has 5 element.
Therefore, the cardinal number of set D = 5. So, it is denoted as n(D) = 5.
(v) Set E = { } has no element.
Therefore, the cardinal number of set D = 0. So, it is denoted as n(D) = 0
Step-by-step explanation:
Using the cardinality concept, it is found that the cardinal number of the set is of 6.
------------------------------------------------------
The cardinality of a set is given by the number of unique elements in the set.For example: set {a,a,a} has cardinality 1, as there is only one unique element, which is a.set {a,b,c} has cardinality 3, as there are three unique elements, which are a,b and c.set {a,a,b} has cardinality 2, as there are two unique elements, which are a and b.------------------------------------------------------
set {a,b,c,d,e,f} has cardinality 6, as there are 6 unique elements, which are: a, b, c, d, e and f. Thus, the cardinal number of the set is of 6.https://brainly.com/question/23976339

Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 36. How old is each
sister?
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer
Step-by-step explanation:
Let x be sister
equation = (x + 2x) = 36
= x = 36/3
= x = 12
kim is 2 times his sisters age so his age is 12×2 = 24

A ladder is placed against a wall. The foot of ladder is 3 feet away from the wall and the top of the latter hits the wall 15 feet of the ground. What is the slope of the ladder?
RIGHT ANSWERS ONLY!
Answer:
5
Step-by-step explanation:
The slope of the ladder is 5.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
Given that, the foot of ladder is 3 feet away from the wall and the top of the ladder hits the wall 15 feet of the ground.
We know that, slope = Rise/Run
Now, slope =15/3
= 5
Therefore, the slope of the ladder is 5.
