We know that that the water level is 3 feet below your deck. (-3)
When the tide goes out, the water level lowers 1 foot. (-1)
A storm surge comes in, the water level rises 2 feet. (+2)
New water level: -3-1+2= -4+2= -2
The new water level is 2 feet below the dock.
Mark as brainliest pls. Any concern or comment, talk to me.
Answer:
9^6
Step-by-step explanation:
When dividing exponents with the same base, we subtract the exponents
a^b/ a^c = a^(b-c)
9^11/9^5 = 9^(11-5)
= 9^6
Answer:
y = -4/3 x=-1/3
Step-by-step explanation:
y = x2 + 2x – 3 and y = x – 1
y= (y + 1)2 + 2(y + 1) - 3 and x= y+ 1
y= 2y + 2 + 2y +2 and x= y+ 1
-3y = 4 and x= y+ 1
y = -4/3 and x = (-4/3) + 1 = -1/3
x2 is x squared or x multiplied by two
There are no real numbers that can do that job.
The numbers are
<em> 1.5 + i √7.75</em>
and
<em>1.5 - i √7.75</em>
These are called 'complex numbers'. The symbol ' i ' stands for √-1 .
==================================================
If either the ' 3 ' or the ' 10 ' was actually supposed to be negative,
then the two numbers would be<em> 2 </em> and<em> -5 .</em>
