Step-by-step explanation:
remember, in a function, x can only have one y, whereas y can have more than one x
Answer:
The first one (the one with the months)
Step-by-step explanation:
A function is when an x value doesn't have more that one y value (y can have more than one x value, though). On the teachers and pets one, Ms. Valverde has two pets, so that doesn't count. On the shapes one, the orange square is pointing to another orange square and a triangle, so that doesn't count. The last one has 7 equaling to 12 and 13, so that doesn't count. The one with the months doesn't have any x values with more than one y value, so it is a function.

Answers
Answer:
The solution set is (5,6).
Step-by-step explanation:
Given equations are:
-6x + 6y= 6 Eqn 1
-6x + 3y=-12 Eqn 2
Subtracting Eqn 2 from Eqn 1
(-6x+6y)-(-6x+3y)= 6-(-12)
-6x+6y+6x-3y=6+12
3y = 18
Dividing both sides by 3
[tex]\frac{3y}{3}=\frac{18}{3}\\y=6[/tex]
Putting y=6 in Eqn 1
-6x+6(6)=6
-6x+36=6
-6x=6-36
-6x=-30
[tex]\frac{-6x}{-6}=\frac{-30}{-6}\\x=5[/tex]
Hence,
The solution set is (5,6).

plissssssssssssss helpppp
Answers
Given that,
Total cost function, C (x) = 43x + $1850
The revenue function R (x) = $80x
To find,
The number of units that must be produced and sold to break even.
Solution,
At break even, cost = revenue
43x + $1850 = $80x
Subtract 80x from both sides.
43x + 1850 -80x = $80x -80x
1850 = 80x-43x
37x = 1850
x = 50
So, the required number of units are 50.

7 + 9.3x = 23
9.3x = 23 - 7 [ 7 becomes -7 when transferred to RHS]

Answers
Answer:
The time required to accumulate simple interest of $ 60.00
from a principal of $ 750.00 at an interest rate of 4% per year is 2 years.
Step-by-step explanation:
Given
Interest I = $60Principle P = $750Interest rate r = 4% = 0.04To determine
Time period t = ?
Using the formula
I = Prt
t = I / Pr
substitute I = $60, P = $750 and r = 0.04 in the equation
t = 60 / ( 750 × 0.04 )
t = 2 years
Therefore, the time required to accumulate simple interest of $ 60.00
from a principal of $ 750.00 at an interest rate of 4% per year is 2 years.

Solving Quadratic Equations using the Square Root Property
[tex]x^2+7x+10=0[/tex]
but the teacher's guide says the answer is 17i
Answers
Answer:
[tex] x = -2 [/tex] or [tex] x = -5 [/tex]
Step-by-step explanation:
You need to complete the square before you can take the square root of both sides.
[tex] x^2 + 7x + 10 = 0 [/tex]
Subtract 10 from both sides.
[tex] x^2 + 7x = -10 [/tex]
To complete the square, you need to add the square of half of the x-term coefficient to both sides.
The x-term coefficient is 7. Half of that is 7/2. Square it to get 49/4. Now we add 49/4 to both sides of the equation.
[tex] x^2 + 7x + \dfrac{49}{4} = -10 + \dfrac{49}{4} [/tex]
[tex] (x + \dfrac{7}{2})^2 = -\dfrac{40}{4} + \dfrac{49}{4} [/tex]
[tex] (x + \dfrac{7}{2})^2 = \dfrac{9}{4} [/tex]
Now we use the square root property, if
[tex] x^2 = k [/tex], then
[tex] x = \pm \sqrt{k} [/tex]
[tex] x + \dfrac{7}{2} = \pm \sqrt{\dfrac{9}{4}} [/tex]
[tex] x + \dfrac{7}{2} = \pm \dfrac{3}{2} [/tex]
[tex] x + \dfrac{7}{2} = \dfrac{3}{2} [/tex] or [tex] x + \dfrac{7}{2} = -\dfrac{3}{2} [/tex]
[tex] x = -\dfrac{4}{2} [/tex] or [tex] x = -\dfrac{10}{2} [/tex]
[tex] x = -2 [/tex] or [tex] x = -5 [/tex]

in a community center 15 bottles are evenly spaced 12 cm apart from each other in a row for a competition
what is the distance from the fourth bottle to the tenth bottle?
Answers
Answer:
72 cm
Step-by-step explanation:
Relative to the first bottle, there are n - 1 spaces between the first bottle and the nth bottle. Since, each bottle is placed relative to the first bottle.
Now, for the fourth bottle, that is, n = 4, there are 4 - 1 = 3 spaces between the first and fourth bottle.
Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 3 = 36 cm.
Now, for the tenth bottle, that is, n = 10, there are 10 - 1 = 9 spaces between the first and fourth bottle.
Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 9 = 108 cm.
So, the distance between the fourth bottle and tenth bottle is distance between tenth bottle to first bottle minus distance between fourth bottle to first bottle = 108 cm - 36 cm = 72 cm

Answers
Complete question :
At 10:00 am, Han and Tyler both started running toward each other from opposite ends of a 10 mile path along a river. Han runs at a pace of 12 minutes per mile Tyler runs at a pace of 15 minutes per mile how far does Han run after a half hour
Answer:
2.5 miles
Step-by-step explanation:
Given :
Distance between Horn and Tyler = 10 miles
Horn's pace = 12 minutes per mile
Tyler's pace = 15 minutes per mile
Horn's distance after half an hour :
Time = Half an hour = 30 minutes
Horn's speed = distance / time
Horn's speed = 1 mile / 12 minutes = 0.83333 miles per minute
Hence, Horn's distance after half an hour :
Distance = speed * time
Distance = 0.83333 miles per minute * 30 minutes
Distance = 2.5 miles

The ratio of teachers to students on a field trip to New York City is 2 to 9.
That is the ratio is 2:9
We are told that there are 243 students
Required
We want to find the number of teachers
Step two:
Applying the part to part method we have
let the number of teachers be x
2/9= x/243
cross multiply we have
9x= 243*2
9x= 486
divide both sides by 9
x= 54
Hence there are 54 teachers
