3.8 repeating or 3 8/9 i think
Hello,
y=x²+2x+7
y=x+7
==>x²+2x+7=x+7
==>x²+x=0
==>x(x+1)=0
==>(x=0 and y=7) or (x=-1 and y=-1+7=6)
Sol={(0,7),(-1,6)}
Answer:
value of n = 2
Step-by-step explanation:

We need to solve the above equation.
Find Least Common multiplier from 5n, 5 = 5n
Multiply both sides of the equation by 5n

Now finding the value of n.
Adding -4 on both sides

Multiplying both sides by -1
n = 2
The value of n is 2.
We can verify by putting value of n in the given question.

So, value of n = 2
The answer is C) x=11/19, y=7/19
So if the delievery man weighs 160 pounds and the books is 40 pounds. and the capacity he can carry is 950 then we have to figure out how many books a 160 can carry.
Division: 160/40=4
950/4=237.5
i tried to answer it. unless i try one more strategy.
Multiply: 160*40=6400
Divison: 6400/950= <span>6.73684210526
</span>try and round that huge number and figure it out. because i tried. im sorry. i hope you passed.
