Answer:

$y=-1$

Step-by-step explanation:

We get the equation $2x-y=1$ , and $x=0$ . Since we know the value of $x$ , that it is equal to 0, we can plug this into the equation for $x$ :

$2(0)-y=1$

From here, we can multiply 2 by 0 and then divide both sides by -1 to isolate $y$ and get what it's equal to.

$0-y=1$

$-y=1$

$y=-1$

Hope this helps!

QveST [7]

Answer:

the answer is 9.69 or if no decimals 10

Step-by-step explanation:

24% of 242 is 58.08 you then divide that number with 6/ the amount of points they get every touchdown. you divide those numbers and you get 9.69.

and that's the amount of points they got but if there aren't any decimals in this question then it would be closer to 100 than it would be 0 so the answer is 10 points

i hope this helped. :)

1000 was invested at 5.5% interest, compounded annually. After sometime the amount had grown to 1550. How long was the money inv

scZoUnD [109]

compound interest equation for annually compounded

$A=P(1+r)^t$

A=final amount

P=principal

r=rate in decimal

t=time in years

given that

A=1550

P=1000

r=5.5%=0.055

find t

$1550=1000(1+0.055)^t$

divide both sides by 1000

$1.55=1.055^t$

take ln of both sides

$ln(1.55)=ln(1.055^t)$

use ln rule $ln(a^b)=b(ln(a))$

$ln(1.55)=t(ln(1.055))$

divide both sides by ln(1.055)

$\frac{ln(1.55)}{ln(1.055)}=t$

using a calculator, we get that t=8.18544 yrs

so about 8.2yrs
