Use the properties of exponents to determine the value of aa for the equation: Screenshot is below

Mathematics
1 answer:
scoray [572]4 years ago
6 0

Answer:

a = -9/20

Step-by-step explanation:

We can evaluate what’s on the left hand side of the equation to get what a is.

The numerator can be expressed as x^(4/5)

The denominator is x^5/4

we use the law of indices to finish this off

That would be;

x^(4/5) ÷ x^(5/4)

Using the second law of indices;

x^(4/5-5/4) = x^-9/20

Since the bases are now equal, then we equate the powers

Thus a = -9/20

What is (4ab^0c^9)^3 ?​
fomenos

Answer:

  64a³c²⁷

Step-by-step explanation:

The expression inside parentheses can be simplified by noting that b^0 = 1. Then you have ...

  (4ac^9)^3

The rules of exponents say the exponent outside applies to each of the inside factors. For c^9, the exponents multiply.

Here are the applicable rules:

  (ab)^c = (a^c)(b^c)

  (a^b)^c = a^(b·c)

__

  (4ac^9)^3 = 4^3·a^3·c^(9·3) = 64a^3c^27

Write the equation of the line that passes through the following points.<br> (3, 1) (1,7)
Marina CMI [18]

Answer:

y=-3x+10

Step-by-step explanation:

Slope formula y2-y1/x2-x1

7-1/1-3

simplify

6/-2

simplify

-3

now plug -3 into y=mx+b

y=-3(x)+b

choose any point and plug it into the equation, I am using (3,1)

1=-3(3)+b

simplify

1=-9+b

add 9 to both sides

b=10

plug into slope-intercept form

y=-3x+10

(y=179x<br> (y=105x+2046<br> Solve using elimination method and graph plss <br> Helpppp
elixir [45]

Answer:

x= \frac{2046}{74}\\\\y = \frac{366234}{74}

Step-by-step explanation:

y = 179x\ ----- ( 1 ) \\\\y= 105x + 2046 \ ----- (2)\\\\

(1) => y - 179x = 0 \ ----- ( 3)\\\\(2) => y - 105x = 2046 \ ------ ( 4)

( 3 ) - ( 4) =>\\\\(-179x +105x ) = 0 - 2046\\\\-74x = -2046\\\\x = \frac{2046}{74}

Substitute \ x \ in ( 1 )\\\\y = 179x \\\\y = 179 \times \frac{2046}{74} = \frac{366234}{74}
