Answer:
y = 22; x = 8
y > x
Step-by-step explanation:
A larger number is double the sum of 3 and a smaller number. The larger number is 2 less than 3 times the smaller number. If y represents the larger number and x represents the smaller number, which equations model the situation? Check all that apply.
Let
Smaller Number = x
Larger number = y
larger number is double the sum of 3 and a Smaller number
Sum of 3 and a smaller number = 3 + x
y = 2(3 + x)
y = 6 + 2x (1)
Also
y = 3x - 2 (2)
Equate the equation of the larger number
6 + 2x = 3x - 2
6 + 2 = 3x - 2x
8 = x
x = 8
Substitute x = 8 into (1) to find y
y = 6 + 2x (1)
y = 6 + 2(8)
= 6 + 16
= 22
y = 22
y = 22; x = 8
Therefore,
y > x
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
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.

Answer:
BC ≈ 8.9 units
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos36° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{BC}{11}[/tex] ( multiply both sides by 11 )
11 × cos36° = BC , then
BC ≈ 8.9 ( to the nearest tenth )

The graph shows the relationship between time
and the number of soda bottles a machine can make use the points 4,180band (7,315) to find the number of soda bottles the machine can make each minute.
Answer:
45
Step-by-step explanation:
The points on the graph :
(4, 180) ; (7, 135)
x1 = 4 ; y1 = 180
x2 = 7 ; y2 = 315
The number of soda bottles the machine can make in a minute is the gradient or slope :
Gradient = change in y / change in x
Gradient = (y2 - y1) / (x2 - x1)
Gradient = (315 - 180) / (7 - 4)
Gradient = 135 / 3
Gradient = 45
Hence, the machine can make 45 soda bottles in a minute.

Solve the system of equations. -12x-5y=40 and 12x-11y=88 x= y=
Answer:
(0,-8)
x=0
y=-8
Step-by-step explanation:
There are a couple of ways you can solve this I used what I think is called the elimination method
We first start by writing the equations in linear form (y=mx+b)
For the first one we have -12x-5y=40
we add 5y to both sides and subtract 40 to get
-12x-40=5y
divide by 5 to get
-12/5x-8=y
Then the second one we have
12x-11y=88
same deal here, add 11y and subtract 88 to get
12x-88=11y
divide by 11 and get
12/11x-8=y
We then set the two equations equal to each other and get
-12/5x-8=12/11x-8
We can add 8 to both sides and get
-12/5x=12/11x
Just by looking at it you can see that the only solution for x is 0
Plug in 0 to the first equation and get -12*0-5y=40
This means that -5y=40
Solve for y and get -8
Answer:
x=0 , y= -8
