Determine if the given value is a solution to the equation.
-8b+5=4; 3/4
is b= 3/4 a solution of equation -8b+5=4
A. yes
B. no
To determine if the given value is a solution to the equation, we substitute b = 3/4 into the equation and check if both sides are equal.
Substituting b = 3/4 into -8b + 5 = 4, we get:
-8(3/4) + 5 = 4
-6 + 5 = 4
-1 = 4
Since -1 does not equal 4, the given value b = 3/4 is not a solution to the equation. Therefore, the answer is:
B. no.
To determine if b = 3/4 is a solution to the equation -8b + 5 = 4, we need to substitute b = 3/4 into the equation and see if it satisfies the equation.
Let's substitute b = 3/4 into the equation:
-8(3/4) + 5 = 4
To simplify, we can multiply -8 by 3/4:
-24/4 + 5 = 4
Simplifying further:
-6 + 5 = 4
-1 = 4
Since -1 is not equal to 4, b = 3/4 is NOT a solution to the equation -8b + 5 = 4.
Therefore, the answer is B) no.
