Answer:
2 non real solutions.
Step-by-step explanation:
We need to use discriminant,
for ax²+bx+c=0
The discriminat is b²-4ac
If the discriminant is,
→ less than 0, then 0 real solutions
→ equal to 0, then 1 real solutions
→ more than 0, then 2 real solutions
Given that,
7x²−4x+3=0
a=7, b=-4, and c=3
→ (-4)²-4(7)(3)
→ 16-84
→ -68
You can see this is less than 0, then non real solutions. [2 nonreal solutions]
Answer:
you will get more money if he gives you 1 cent per day then doubles it
Step-by-step explanation:
if your brother gives you 25 cents per day, at the end of 10 days you will have $2.50
if he gives you 1 cent per day then doubles it, this will be your daily earnings:
day 1- 0.01
day 2- 0.02
day 3- 0.04
day 4- 0.08
day 5- 0.16
day 6- 0.32
day 7- 0.64
day 8- 1.28
day 9- 2.56
day 10- 5.12
then when you add all of this up, you would recieve 10.23 cents at the end of day 10
The slope is 1. The picture will show you why.
