Step-by-step explanation:

step 1. a function must only have a single y value for each x value.

step 2. for the input x, there can only be one output or result y.

step 3. #1 is a function because for each x there is only one y.

step 4. #2 and #3 are functions also.

step 5. #4 is not a function because (1, 1) and (1, -1) says x is 1 but the y is both 1 and -1 (2 values)

step 6. (2, 2) and (2, -2) also makes #4 not a function.

In a Washington town, the charge for commerical waste collection is $694.55 for 5 tons of waste and $1098.56 for 8 tons of waste

NISA [10]

Answer:

$m =\frac{1098.56-694.55}{8-5}= 134.67$

And we can find the intercept like this:

$694.55 = 134.67*5 +b$

$b = 694.55 -673.35= 21.2$

And the equation would be given by:

$C = 134.67 w + 21.2$

Step-by-step explanation:

For this case we want a function given by:

$C = mw +b$

Where C is the cost, m the slope, w the weight and b the intercept.

We have the following info (w=5, C= 694.55) and (w=8, C=1098.56) and we can find the slope with this formula:

$m =\frac{1098.56-694.55}{8-5}= 134.67$

And we can find the intercept like this:

$694.55 = 134.67*5 +b$

$b = 694.55 -673.35= 21.2$

And the equation would be given by:

$C = 134.67 w + 21.2$

Babatunde has a mass of 78kg. What would Babatunde weigh on the Moon? (The gravitational field strength on the Moon is 1.6N/kg.)

Rina8888 [55]

Answer:

Babatunde weigh on the Moon would be 124.8 N

Step-by-step explanation:

* The wight of an object on the earth is mg , where m is the the

mass of the object in kg and g is the acceleration of gravity which

is 9.8 m/s²

* The mass of an object on earth is the same as the mass of the

same object on the moon but the weight of the object on the

earth is different from the weight of the same object on the

moon because the gravity on the earth different from on the moon

* The wight on the moon is mg , where m is the the mass of the

object in kg and g is gravitational field strength on the Moon

which is 1.6 N/kg

∵ Babatunde has a mass of 78 kg

∵ The mass on the moon = the mass on the earth

∵ On the moon the gravitational field strength is 1.6N/kg

∵ Weight = mg

∴ Babatunde weigh = 78 × 1.6 = 124.8 N

* Babatunde weigh on the Moon would be 124.8 N

If the number of $8 child tickets is 17 less than 3 times the number of $12 adult tickets and the theater took in $584, how many

slava [35]

Answer:

The number of child tickets sold was 43 and the number of adult tickets sold was 20

Step-by-step explanation:

Let

x ----> the number of child tickets sold

y ----> the number of adult tickets sold

we know that

$x=3y-17$ -----> equation A

$8x+12y=584$ ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (43,20)

see the attached figure

therefore

The number of child tickets sold was 43 and the number of adult tickets sold was 20
