Answer:
28t^19
Step-by-step explanation:
4t^7 * 7t^12
Deal with the integers and indices seperately.
4 * 7 = 28
t^7 * t ^12 = t^7+12 = t^19
90,000 is the correct answer
So right of the bat the equation we know from what's given is y = 2x (+b)
we gotta find out what b is
so we plug the coordinate in
3=8+b.
b=-5
so we put all the pieces back together to get
y = 2x - 5
Answer:
79 dollars
Step-by-step explanation:
a = 51 + b
Substitute the number of books, 28, he sold into the equation and solve for his earnings.
a = 51 + b
a = 51 + 28
a = 79
Hey there. So basically, find out how much the pencils and notebooks cost first.
The notebooks cost = $3.25
The pencils cost = $0.50
Then, think about what you need to figure out in this problem.
Jake has $20. You need to find how many notebooks Jake can buy in maximum after buying 8 pencils.
If Jake buys 8 pencils that costs $0.50 each, he spends $4 on the pencils.
So now, to find out how many notebooks he can buy, do 20 minus 4.
Jake's got $16 left.
If the notebooks cost $3.25 each, we need to find out how many notebooks he can buy by dividing them. So, 16 divided by 3.25 equals 4.923... and so on.
That means, Jake can buy 4 notebooks with his remaining money.
