Answer:
Which expression is equivalent to ((4^((5)/(4)).4^((1)/(4)))/(4^((1)/(2))))^((1)/(2))?
You flip is when you mulitply the whole equation by a negative
not when you distribute a negative
if yo had
-3(x+4)>x
you wouldn't flip the negative symbol when distributing then -3
but if you had
-3(x+4)>-x
you would eventually have to multiply by -1 to make +1x
because they will be differente
exaple
12>3 is true
if yo multiply negative
-12>-3 is fale
-12<-3 is true
anothe rexample with placeholders
x<x+2
mulitply -1
-x>-x-2
false
-x<-x-2
true
that is why we flop the inequality symbole
The answer should be The B
C) a relation is when an x value is correlated with only one y-value. If this is not the case, the equation siezes to be a relation.
Hope I helped :)
Answer:
step 1. x = 2y - 4 on the 1st equation
step 2. 5(2y- 4) - 6y +18 = 0 plug x from 1st equation into the 2nd equation
step 3. 10y - 20 - 6y + 18 = 0
step 4. 4y - 2 = 0
step 5. y = 1/2
step 6. x = -3 plug y into 1st equation
step 7. (-3, 1/2) is the answer.
