Note that ∠A + ∠B = 180°
Therefore:
(8x + 74°) + (2x + 56°) = 180°
Simplify:
10x + 130° = 180°
Subtract both sides by 130°:
10x = 50°
Divide both sides by 10:
x = 5
Plug x into ∠B:
∠B = 2(5) + 56° = 10 + 56° = 66°
Answer:
y=log3(9x)
3^y = 9x
Step-by-step explanation:
Answer: 1) Product property of logarithm,
2) Subtraction property of logarithm
3) Equality property of logarithm
Step-by-step explanation:
By the Product property of logarithm,
log a + log b = log(a.b)
And, By the Subtraction property of logarithm
log a - log b = log(a/b)
Also, by the equality property of logarithm,
log(a) = log(b) ⇒ a = b
Given expression,
(Product property of logarithm)
(Subtraction property of logarithm)
( Equality property of logarithm )
( Multiplicative property of equality )
( Distributive property of equality )
(subtraction property of equality )
(division property of equality )
-1/2x+3=-x+7
Multiply throughout by 2x
-1+6x=-2x^2+14x
2x^2-8x-1=0
