Assuming your first equation is y = 5x+9, the equations describe lines that are coincident.
_____
Multiplying the second equation by -1, it becomes y = 5x+9, the same as the first equation.
Answer: This expression is equivalent to 3^x
Step-by-step explanation: In this question the important concept is to write 80 in exponential form and multiply the exponents.
=80^1/4x
=(3^4)^1/4x
=3^x
Answer:
if Bobs want to make $6000 commission he needs to make $120,000 sales.
*choices d
Step-by-step explanation:
in $3000, the 5% of Bobs commission is $150
*solution
5% is equivalent to 0.05 in decimal
3000 × 0.05 = 150
so just divide the 5% to $6000 to get the sales
*solution
$6000 ÷ 0.05 = $120,000
Answer:
The answer is 8.
Step-by-step explanation:
We need to use the quadratic formula, that is ax2+bx+c=0
Where
For the given equation x2+5x-104=0 we have
a=1, b=5, c= -104
If you solve that, we will have x=-13. x=8, two answers,
The first one, by being negative does not have physical sense (there are no negatives quantities when you measure the length of something)
So we use the anwser x=8
