First we rewrite the expression:
 (5 ^ -1) * (5 ^ -3)
 Using properties of exponents we have:
 (1/5) * (1 / (5 ^ 3))
 Rewriting:
 (1/5) * (1 / (125))
 1/625
 answer:
 An equivalent expression is:
 1/625

Answer:
1/625

Explanation:
In case of multiplication of numbers with same base, we add the powers.
This means that:
a^x * a^y = a^(x+y)

Applying this to the given, we will find that:
(5^-1) * (5^-3) = 5^(-1-3)
                      = 5^-4
                     = 1/625

Hope this helps :)

Points A B C D and E are collinear and in that order. Find AC if AE=x+50 and CE=x+32
Lana71 [14]

Answer:

18

Step-by-step explanation:

Points A B C D and E are collinear.

\therefore AE = AC + CE\\\therefore AC = AE - CE\\\therefore AC = x + 50 - (x + 32) \\\therefore AC = x + 50 - x - 32 \\\therefore AC =  50 - 32 \\ \huge \red{ \boxed{\therefore AC = 18}}

Write an equation of the line through (3,-5) and perpendicular to 3y=x-6
Alona [7]
3y = x - 6
y = 1/3x - 2. 
slope her is 1/3. A perpendicular line will have anegative reciprocal slope. To find the negative reciprocal of a number, u flip the number and change the sign. So the slope we need os -3/1 or just -3.(see how I flipped the slope and changed the sign)

y = mx + b
slope(m) = -3
(3,-5)...x = 3 and y = -5
now we sub and find b, the y int
-5 = -3(3) + b
-5 = -9 + b
-5 + 9 = b
4 = b

so ur perpendicular equation is : y = -3x + 4

Which is 5logx - 6log(x-8) written as a single logarithm?
ira [324]

Answer:

option a

log\frac{x^{5} }{(x-8)^{6} }

Step-by-step explanation:

Given in the question an expression

5logx - 6log(x-6)

To solve this question we will apply two of the logarithm property

1) power rule

alogx = logx^{n}

logx^{5} - log(x-8)^{6}

2) substraction rule

The log of a quotient is the difference of the logs

loga (x/y) = loga x - loga y

logx^{5}- log(x-8)^{6}

log\frac{x^{5} }{(x-8)^{6} }

Pleeeeease help me out!!!!!
Nataly_w [17]

If you look at the data, you can see that every y value is opposite to the corresponding x- value.

So, equation can be written as

y = [-] x or y=[-1]x
