Silver for x
-3 - (-8) - (-2) = x
Switch the equation to make x on the right
x = -3 - (-8) - (-2)
x = 5 - (-2)
x = 7
• A negative minus a negative will always evaluate to a positive.
• A positive minus a negative will always evaluate to a positive.
Answer:
Step-by-step explanation:
Given
Required
Determine the roots
To get the root of the function, then f(b) must be 0;
i.e. f(b) = 0
So, the expression becomes
Add 75 to both sides
Take square roots of both sides
Reorder
Expand 75 as a product of 25 and 3
Split the expression
The options are not clear enough; however the roots of the equation are
Answer:
1/2
Step-by-step explanation:
8(1/2)^4
= 8 * 1 / 2^4
= 8/(2*2*2*2)
= 8/16
= (8*1) / (8*2)
= 1/2
Answer:
8/15
Step-by-step explanation:
you first want to change your whole number, 4, into a fraction so all you have to do is add a 1 in the denominator so it will be 4/1
then you multiply across
2/15 * 4/1
you first multiply 2 and 4 and your answer will be 8 which is the numerator
then multiply 15 and 1 which is 15, the denominator
then you get
8/15
