7800, because 7782 is closer to 7800 than 7700
Wouldn’t you just for part a, insert different x values and solve to get your y value. and do that over and over again with different numbers to create a data table. and then for part b you’ll just make a graph and put down the points. so for the first slot, do 0 for x. y will equal -1 after solving, so your first plot for part b can be (0,-1) and continue on from there
In December she would have saved $1585 because 1235 + 250 = 1485. You can find how much money she raised in those 2 months by adding the totals of both months together, so 1485 + 1235 = 2720. She saved $2720 in the 2 months.
Answer:
(3x^2+6x)/(x^2-16)
Step-by-step explanation:
When multiplying fractions you just go straight accross
this means that our fraction is equal to
((x+2)(3x))/((x-4)(x+4))
The numerator is quite easy 3x(x+2)=3x^2+6x
The second one is a little tough at first and if you need help I would reccomend using khan academy
but pretty much you get x^2-16
put them together and get your answer
