Answer:
81x4 = (9x^2)^2, 121a6 = (11a^3)^2, 0.09y12 = (0.3y^6)^2, 4/9b6 = (2/3b^3)^2
Step-by-step explanation:
sqrt of 81 = 9, (we do sqrt because its the inverse to exponents) x^4, x^2 * x^2 = (9x^2)^2
sqrt of 121 = 11, a^6, a^x * a^2 = a^6, x = 3, (11a^3)^2
sqrt of 0.09 = 0.3, y^12 = y^x * y^2, x=6,(0.3y^6)^2
sqrt of 4/9 = 2/3, b^x * b^2 = b^6, x = 3, (2/3b^3)^2
^ = power, * = multiplication
6. The answer is 208
8. The answer is 285
-3(1+6x) = 14 - x
-3 -18x = 14 -x
-18x +x = 14 + 3
-17x = 17
x = -17/17
x = -1
Therefore x is equal to -1.
Answer:
t = 9
Step-by-step explanation:
Step 1:
- t = 9 ( t - 10 ) Equation
Step 2:
- t = 9t - 90 Multiply
Step 3:
- t + 90 = 9t Add 90 on both sides
Step 4:
90 = 10t Add t on both sides
Step 5:
t = 90 ÷ 10 Divide
Answer:
t = 9
Hope This Helps :)
g(x) = 0
This is asking at what x value does y = 0. g(x) = y
y = 0, when x is 6
