Answer:
b = 141
Step-by-step explanation:
b − –573 = 714
Subtracting a negative is adding
b + 573 = 714
Subtract 573 from each side
b − 573+573 = 714-573
b =141
The second graph because 2x5=10, 4x5=20, 6x5=30!
Answer:
X^5+3x^4+81x+ 243
Step by step:
X^4*x=x^5
X^4*3=3x^4
81*x=81x
81*3=243
Answer:
8 = y
Step-by-step explanation:
In order to find a solution to an algebraic equation such as this one we simply need to isolate the variable. We do this by applying the opposite operation to each side in order to get rid of the other factors and get the variable alone. Like so...
20 = y + 12 ... we need to subtract 12 from both sides to get rid of the 12 on the right side with the variable y.
20 - 12 = y + 12 - 12
8 = y
Finally, we can see that the value of the variable y is 8
