B no solution -3<-12 cant be answer
Answer:
Step-by-step explanation:
We have the equation:
Let's simplify this a bit. Let . Then . We can substitute the exponents:
Use the properties of exponents, we can write . We can do the same thing on the right. So:
We can now factor out a from the left and a on the right. This yields:
Evaluate the expressions within the parentheses:
Evaluate:
Now, let's multiply both sides by . So:
Also, let's divide both sides by . Multiply on the right:
Therefore:
We can now substitute back u. Notice that 27 is the same as 3 cubed and 1000 is the same as 10 cubed. So:
Since they have the same base, their exponents must be equal. Therefore:
Add 2 to both sides:
So, the value of x is 5.
And we're done!
Answer:
x < -3
Step-by-step explanation:
-4x - 10 < 2
-4x < 12 (+10)
-x < 3 (÷4)
x < 3 (+x, -3)
it's both a function and relation a function because it has independent variable and dependent variable and it's a relation because there is a relationship between the values
<h3>Answer: 2.25</h3>
==================================
Explanation:
Multiply the values in the second and third columns. Do this row by row.
Row1: 3*20 = 60
Row2: 2*12 = 24
Row3: 1*6 = 6
Row4: 0*2 = 0
Add up the products to get 60+24+6+0 = 90
Then divide this by the total frequency 20+12+6+2 = 40 to get 90/40 = 2.25
