Answer:
sqrt(ac)
±---------- = b
3c
Step-by-step explanation:
a= 9b^2 c
Divide each side by 9c
a/9c = 9b^2c / 9c
a/9c= b^2
Take the sqrt of each side
±sqrt(a/9c) = sqt(b^2)
Remember that sqrt (xy) = sqrt(x) sqrt(y)
±sqrt(a/c) * 1/ sqrt(9) = b
±sqrt(a) 1
--------- * ------ = b
sqrt(c) 3
Multiply by sqrt(c)/ sqrt(c)
±sqrt(a) sqrt(c)
--------- * ----------- = b
sqrt(c) 3sqrt(c)
±sqrt(ac)
---------- = b
3c

Answer:
the equation will be:
solving the equation we get x=8
Option B is correct.
Step-by-step explanation:
We need to write equation for this sentence:
The difference between a number and five equals three.
Let number = x
So, the equation will be:
Now, solving the equation to find value of x
Adding 5 on both sides
So, solving the equation we get x=8
Option B is correct.
Answer:
A. y=-2x+5
Step-by-step explanation:
y=mx+b , m represents slope (-2), b represents y intercept (5)
Alright. -2-(-4) = -2 + 4 because a negative and a negative equals to a positive[(-2-(-4)]. It would look like: Put a dot on -2, then move your dot 4 units to the right, which is +2.
