Answer:
Step-by-step explanation:
equation of line formula:
m = slope
c = y-intercept
1) find m
slope formula:
take 2 coordinates from the given graph and substitute the values into the slope formula
i) (-1,0)
ii) (3,2)
substitute the values into the slope formula
2) find the half equation of the line by substituting the value of m into the equation of line formula
3) find c by substituting either coordinate into the half equation
(3,2)
x = 3
y = 2
4) find equation of line by substituting the value of c into the half equation

1. 6a+4c=88
12a+9c=186
2. so you need to multiply the top number by -2 so you can cancel out the 12a
-2(6a+4c=88)=. -12a-8c=-176
3. then you add them all together
12a+9c=186
-12a-8c=-176
——————————-
c=10
4. now you have to find ‘a’
6a+4(10)=88
6a+40=88
-40. -40
6a=48
divide both sides by 6
a=8
And your final answer should be (8,10)

Answer:
Step-by-step explanation:
Question 1. 50% of what number is 100?
Number = x
50%x = 100
5x/10 = 100 (50% = 2/10)
5x = 1000 (Multiplying by 10 at both sides of the equation)
<u>x = 200</u> (Dividing by 5 at both sides of the equation)
<u>Part 50 Whole 100 Part 75 Whole 150 Part 100 Whole 200</u>
Question 2. 25% of what number is 30?
Number = x
25%x = 30
x/4 = 30 (25% = 1/4)
x = 120 (Multiplying by 4 at both sides of the equation)
<u>Part 25 Whole 30 Part 50 Whole 60 Part 75 Whole 90 Part 100 Whole 120</u>
<u>Question 3. What did you differently to find the whole using a ratio table?</u>
Using a ratio table is a much more simple path to get the whole. I take it and just calculate the double of the information given to me for completing the next values in my table, until I get the part 100 and its correspondent whole.
Answer: New York population is bigger by 580,000 ,which can be written in standard form as 5.8 x
Step-by-step explanation:
2 x can be written in ordinary number as 20,000
6 x can be written in ordinary number as 600,000
With this , it is clear that New York has a larger population.
The difference in their population will be
600,000 - 20,000 = 580,000
Answer:
y = 3.25x - 21
Step-by-step explanation:
Find the slope using the formula below. Once you've found the slope, plug 0 in for X to find the Y intercept.
