Answer:
B.
Step-by-step explanation:
Both equations use x squared
Hi,
The answer is 3/2 or 4
How I got my answer:
Just think that (2x+3) OR (x-4) has to be 0.
<span>
Than you can find it out with a simple +/- calculation. </span>
<span> 2x+3=0 x-4=0
x=-3/2 or 4</span>Hope this helps you.
B is correct. Substitute the week number for w in the function. Follow order of operations and you should get you N, the number of fruit flies for that week. For instance week 2:
N= 2(5)^2-1
N=2(5)^1
N=2(5)
N= 10
N= 10 corresponds to the table
Answer:
It's 19.
Step-by-step explanation:
Use order of operations (PEMDAS):
2^2[4+(3-6)^2]-13
Parentheses first:
= 2^2[4 + (-2)^2] - 13
= 2^2 ( 4 + 4) - 13
= 2^2 * 8 - 13
Now work out the exponent:
= 4*8 - 13
Now the multiplication:
= 32 - 13
= 19.
X = (2^2)^(2.5)
<span>x = 2^(2 * 2.5) </span>
<span>x = 2^5 </span>
<span>x = 32
</span>y^(-3/2) = 125
<span>y^(-3) = 125^2 </span>
<span>y^(-3) = (5^3)^2 </span>
<span>y^(-3) = (5^2)^3 </span>
<span>y^(-3) = 25^3 </span>
<span>y = 25^(-1) </span>
<span>y = 1/25 </span>
<span>x/y => </span>
<span>32 / (1/25) => </span>
<span>32 * 25 => </span>
<span>800 is the simplest form of above
</span>
