Graph is attached
Step-by-step explanation:
we are given
It costs $145 for 10 people to attend a concert
(a)
Number of people =10
Total cost =145
now, we can find constant proportionality
k= ( total cost)/(number of people)
(b)
Let's assume
cost is C
number of people as x
so, we can set equation as
now, we can plug value
(c)
we can plug x=8
C=116
So,
the cost of 8 people is $116
(d)
we can draw graph

The simplified product of and -3 is -30.
Given Two expressions: -3 and 2.
We have to multiply both the expressions and it can be done as under:
-3 *2
Firstly we have to multiply -3 with 2 to get
=-6
Then we have to find square root of x cube and x square which is x to the power 3/2 and x to the power 1.
=
Now we have to multiply both the numbers in the root to get the answer;
=-6
Square root of 50 is 5 root 2.
=-6*5
=-30
Hence the simplified product is -30.
