This is fairly easy, all you need to do is write the ordered pairs for each graph, for these there are 5 ordered pairs for both.
In order to create the ordered pair all you need is this 'formula' of (x, y)
In the first graph 'input' would be the x value and output is the y value. So all you do is plug them into the formula.
(-10,-20)
(-5,-10)
(0,0)
(5,10)
(10,20)
Those are all the ordered pairs for graph A. Now just do the same thing for graph B.
2. If Greg drove 135miles in 3 hours, we must divide the number of miles by the number of hours to determine how many miles per hour he traveled:
135/3= 45mph
3. If she is payed $45 for 5 hours, we must divide the amount of money by the number of hours to find how much money she made per hour:
45/5= 9 dollars per hour
4. if she payed $0.72 for 8 ounces of water, we must divide the cost by the number of ounces to find out how much they spent per ounce:
.72/8= .09 dollars per ounce or 9 cents
1. The answer will be less than one. We know this because a positive number that is multiplied by a negative number will always equal a negative number and therefore be less than one.
Answer: the answer is 7
Step-by-step explanation: add 9 to both sides, eliminating -9 so now you have 7x=49 divide both by 7 and you get x= 7 check it by inputing 7 for x, 7(7)-9=40
7(7)=49 next 49-9= 40
it checks out, so x= 7
