Answer:
#1: (0,0)
#2: (0,-3)
#3: (0,1)
#4: (0,1)
Step-by-step explanation:
The y-intercept is the value of y when x equals 0.
So, we should plug 0 in for x, and solve for y.
For #1, we get 2y=4(0), so 2y=0, meaning that y=0, thus the y intercept is (0,0).
For #2, we get -2y=4(0)+6, so -2y=6. Dividing both sides by -2, we get y=-3, and the y-intercept is (0,-3).
For #3, plugging in x for 0, we get 2y-2=-(0), so 2y-2=0. We can add 2 to both sides, and divide both sides by 2, so we have y=1, and the y-intercept is (0,1)
For #4, we get -2y+2=2(0), so -2y+2=0. If we subtract 2 from both sides, then divide by -2, we get y=1, and the y-intercept is (0,1).

Fishing Adventures rents small fishing boats to tourists for day-long fishing trips. Each boat can only carry 1200 pounds of people and gear for safety reasons. Assume the average weight of a person is 150 pounds. Each group will require 200 Ibs of gear for the boat plus 10 lbs of gear for each person. Create an inequality describing the restrictions on the number of people possible in a rented boat. Graph the solution set on a number line.
Answer:
To write an inequality that illustrates the weight limit for a group of adults and children on the fishing boat, let's assume that the letter a corresponds to the number of adults and the letter c corresponds to the number of children.
So, let's calculate:
The total weight on the boat by people corresponds to:
Now, let's add 200 pounds of equipment to this amount, and remembering that the total weight cannot exceed 1200 pounds, so we will find the following inequality:
Or else:
The next step is to calculate the inequality for the passenger limit, remembering that this number cannot exceed 8:
Thus, we find a system of linear inequalities:
In order to be able to answer which of the groups can safely rent a boat, we will make the following calculations substituting the values in the inequalities found.
Group A has 4 adults and 2 children:
Group B has 3 adults and 5 children:
Group C has 8 adults and 0 children:

ANSWER:-
Yes,
There is a direct proportional relationship
between the cost of items before tax and the
cost of items after tax.
5.0
STEP-BY-STEP EXPLANATION:-
Given - A city has a 5% sales tax.
To find - Is there a proportional relationship
between the cost of items
before tax and the cost of items after
tax?
PROOF:-
Yes, the cost of items before tax is directly
proportional to the cost of items after tax.
REASON:-
With the increase in the sales tax, there is
increase in the cost of items after tax, therefore,
there is a direct relation between the cost of items
before tax and cost of items after tax

Determine the probability that a student studied for 5 hours.
23.0
0.70
0.23
0.16
The probability that a student studied for 5 hours is 0.23 Or 23%.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
A table is given where the first column represents the number of hours a student studied maths and the second column represents the number of students.
The sum of the second column is 30 so it is the total number of students
And only 7 of them studied mathematics for 5 hours.
Therefore, The probability that a student studied for 5 hours is,
= 7/30.
= 0.23 or 23%.
