Answer:
The first step is
Take the square root of both sides of the equation
Step-by-step explanation:
we have

Solve for x
step 1
Take square root both sides

the solutions are
and 
therefore
The first step is
Take the square root of both sides of the equation
"More than" indicates addition, and "product" indicates multiplication.
The inequality is:
5 + 8n >= 100
Now we can solve for all positive values of n:
5 + (-5) + 8n >= 100 + (-5)
8n >= 95
8n/(8) >= 95/(8)
n >= 11.875
So all positive values of n include everything between 11.875 and positive infinity, inclusively.
Answer:
TRUE!
Step-by-step explanation:
Answer:
The system has infinite solutions
Step-by-step explanation:
Notice that the 2nd eq can be written as y=3x+2, exactly the same first equation, so it doesnt give anything to solve it
You can see the attached picture represents the eq. 1
The second eq. is also represented in that picture, just it doenst seems, because it is hide under the first
Answer:
$8
Step-by-step explanation:
The formula for simple interest is i = p*r*t, where r is the interest rate as a decimal fraction.
Here, i = $80*0.10*1 = $8
