Answers

Ok, so I think

X=(90-6y-7z)/5

Y=(90-5x-7z)/6

Z=(90-5x-6y)/7

I think they are related because all of the answers (a)-(c) have 90 subtracted by the following variables. Also all of the results include fractions... I don’t know for sure if this answer is right though, sorry!! I hope this helps a little though, good luck!!

How to find value of complex number from graph?

To find the value of a complex number from the graph, follow the steps below.

On the graph where x-axis represents the real line, the distance of the point give the real number.On the graph where y-axis represents the imaginary line, the distance of the point give the imaginary number, which is written with complex number i.

The image shows w and z + w. The point w is 1 units left from the imaginary axis. Thus, the real number for w is -1.

This number is 2 units down. Thus, the complex number represent the point w is,

[tex]w=-1-2i[/tex]               ......1

Similarly, z+w is 4 units left and 4 units up. Thus, the complex number represent z+w is,

[tex]z+w=-4+4i[/tex]                   ......2

Substrate equation 1 from equation 2,

[tex]z+w-w=-4+4i-(-1-2i)\\z=-4+4i+1+2i\\z=-3+6i[/tex]

Hence, In the image which shows the complex number w and z+w, the value of the complex number Z is -3+6i.

The total cost in dollars for Larry to have his birthday party at a local
Trampoline Park can be found using the function t = 6.95p + 29.95, where p is
the number of people who will attend the party. If Larry only has $70 to spend on
his party, which of the following could represent the domain of the function?

Answers

Answer:

He can have 5 people at max

Step-by-step explanation:

He can only have 5 people at max which would cost $64.70, since if there were one more it'd cost $71.65. So the equation would be

T = 6.95p + 29.95 { 0 ≤ x ≤ 5 }

The domain can be represented as 0 ≤ p < 6

What is domain of the function ?

Domain is the set of all inputs for which the function is valid, whereas the range of a function is the set of outputs that the function will produce. Also, we can define domain and range as, domain is the set of numbers which are valid values for the independent variable. The range is the set of valid numbers for the dependent variable.

We have

t = 6.95p + 29.95

Amount =  $70

Required

Determine the domain

First, we need to solve for p

Substitute  $70 for t in  t = 6.95p + 29.95

70 = 6.95p + 29.95

Collect Like Terms

6.95p = 70 - 29.95

6.95p = 40.05

Solve for p

p = 40.05/6.95

p = 5.76

This implies that Larry can not invite up to 6 people.

Hence, the domain can be represented as 0 ≤ p < 6
