Ok so we'll go ahead and solve for y first - we just need to get it alone on one side of the equal sign
Step 1: subtract 2x from each side
2x - 7y - 2x = 19 - 2x
This cancels out the 2x on the left, giving us
-7y = 19 - 2x
Step 2: divide both sides by -7
= 
+ 
This gives us
y = -19/7 + 2x/7
That should be your answer for the first question. Now solving the next parts are easy. All you need to do is plug in x.
When x = -3
y = -19/7 + 2x/7
y = -19/7 + 2(-3)/7
y = -19/7 - 6/7
y = -25/7
When x = 0
y = -19/7 + 2x/7
y = -19/7 + 2(0)/7
y = -19/7
When x = 3
y = -19/7 + 2x/7
y = -19/7 + 2(3)/7
y = -19/7 + 6/7
y = -13/7
Hope that helps! Feel free to ask if I can help with anything else :)
Step-by-step explanation:
Given
A proportional relation is given between minutes spend in reading and no of pages
Suppose we choose the point 
, It shows that 2 minutes is taken to read three pages.
Similarly, for point 
, It shows four minutes is taken to read 6 pages.
In this way, 6 minutes is taken for 12 pages.
Answer:
Experimental probability is likely to be slightly different from theoretical probability.
Step-by-step explanation:
This is because there is a 50-50 chance, but it is unlikely to be exactly 100-100. That is just to hypothesis!
64/1×5/8=320/8. 320÷8=40. There is 40 gallons of gas in the truck
Answer: 3.3 times 10^5 is bigger
Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.
so 100,000 multiplied by 3.3 = 330,000
or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.
