Answer:
c) 2⁻⁹
Step-by-step explanation:
1) use negative power rule: [tex]x^{-a} =\frac{1}{x^{a} }[/tex]
1/2⁹
2) simplify ₂⁹ to 512
1/512 ( same as (8) ⁻3
Answer:
c
Step-by-step explanation:
Using the rule of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
note that 8 = 2³ , then
[tex](8)^{-3}[/tex]
= [tex](2^3)^{-3}[/tex]
= [tex]2^{3(-3)}[/tex]
= [tex]2^{-9}[/tex] → c

Answer:
x • (x^3 - 3x^2y + 3xy^2 + 7y^3)
Step-by-step explanation:
(8x • (y^3)) + x • (x - y)^3
2^3xy^3 + x • (x - y)^3
Evaluate : (x-y)^3 = x^3-3x^2y+3xy^2-y^3
Pull out like factors :
x^4 - 3x^3y + 3x^2y^2 + 7xy^3 =
x • (x^3 - 3x^2y + 3xy^2 + 7y^3)
x^3 - 3x^2y + 3xy^2 + 7y^3 is not a perfect cube

1) Let L = the larger # and S = the smaller #.
A large # is 5 more than twice a smaller #.....This gives Eq 1) L = 5 + 2S
Their sum is 80...This gives Eq 2) L + S = 80.
Substitute Eq 1) into Eq 2), you get
L + S = 80
5 + 2S + S = 80
3S = 75
S = 75 / 3 = 25
L = 5 + 2S
= 5 + 2(25)
= 5 + 50
= 55

(4,-3),m=-1 in standard form
Answer:
Step-by-step explanation:
m = -1 ; ( 4 , -3)
y - y1 = m(x - x1)
y - (-3) = -1(x - 4)
y+ 3 = -x + 4
Add x to both side.
x +y + 3 = 0
Subtract 4 from both sides
x + y + 3 - 4 = 0
x +y - 1 = 0

Answer:
n = 27
Step-by-step explanation:
Multiplication has the commutative property, which means it doesn't matter what way around you put the numbers e.g. 4 × 3 = 3 × 4
So 27π = 27 × π = π × 27
n is 27
hoose the statement that describes its
solution.
3(x + 8) - 9x = 6(4- x)
O There is no solution.
оо
There is only one solution.
ws
о
All real numbers are solutions.
Answer:
3rd option
Step-by-step explanation:
3(x + 8) - 9x = 6(4 - x) ← distribute parenthesis on both sides
3x + 24 - 9x = 24 - 6x , collect like terms on left side )
24 - 6x = 24 - 6x
Since both sides are the same then any value of x will make the equation true.
That is all real numbers are solutions

which line is parallel to the line whose equation is 4x 3y = 7, and also passes through the point (- 5, 2)?
Answer: [I assume: "4x 3y = 7" is really 4x + 3y = 7]
y = -(4/3)x -14/3
Step-by-step explanation:
Rewrite this as y=mx+b, where m is the slope.
4x + 3y = 7
3y = -4x +7
y = -(4/3)x +(7/3)
The slope is -(4/3)
A parallel line will have the same slope, but a specific value of b to allow it to go through the given point (-5,2):
y = -(4/3)x + b
Enter the point and solve for b:
2 = -(4/3)(-5) + b
2 = (20/3) + b
b = 2 - (20/3)
b = 6/3 - 20/3
b = -14/3
y = -(4/3)x -14/3
