Answer:
Jordan made mistake in his first step while multiplying.
Step-by-step explanation:
Given expression of Jordan's work is
14(8+4x) = 6x-(5-11x)
In the first step, Jordan multiplied the numbers to remove the braces.
He multiplied 14(8+4x) wrong as 14*8 is 112 rather than 126and on the right hand side, he did not change the sign of 11x to positive as two negatives are positive when multiplied.
Hence,
Jordan made mistake in his first step while multiplying.
open () to make 9f-6>5f-3
minus 5f to make 4f-6>-3
add 6 to make 4f>3 so f >3/4
Answer:
Step-by-step explanation:
The domain of a function is all of the values that 
can be under that specific function. In this case, we're asking what values of allow 
to exist.
In order for square roots to exist, the quantity under the square root must be greater than or equal to 
, because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for :
Solving this inequality, we get:
(Subtract 
from both sides of the inequality to isolate )
(Multiply both sides of the inequality by 
to get rid of 's coefficient)
Hope this helps!
You solve an expression for a variable if that variable sits alone on one side of the equation, and everything else is on the other side.
So, our goal is to leave 
alone on the right hand side, and move everything else to the left.
So, we start with
We multiply both sides by 3:
We divide both sides by 
To compute the required height, simply plug in the values:
The ratio of left handed to right handed people is 1:4
Therefore the ratio of left handed to total people is 1:5
Set up a proportion
1/5= x/30
5*6=30
1*6=6
x=6
Final answer: 6 left handed people
