Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Using the rule of exponents / radicals
[tex]a^{\frac{m}{n} }[/tex] = [tex](\sqrt[n]{a})^m[/tex]
[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex] , then
[tex]-8^{-\frac{2}{3} }[/tex]
= [tex]\frac{1}{-8^{\frac{2}{3} } }[/tex]
= [tex]\frac{1}{(\sqrt[3]{-8})^2 }[/tex]
= [tex]\frac{1}{-2)^{2} }[/tex]
= [tex]\frac{1}{4}[/tex]

Solve for x.
−2(4x+4) - 3x - 2 = 34
Answer:
[tex] - 2(4x + 4) - 3x - 2 = 34 \\ \\ - 8x - 8 - 3x - 2 = 34 \\ \\ - 8x - 3x = 34 + 8 + 2 \\ \\ - 11x = 34 + 8 + 2 \\ \\ - 11x = 44 \\ \\ x = - \frac{44}{11} \\ \\ x = - 4[/tex]
Answer:
[tex]−2(4x+4) - 3x - 2 = 34 \\ - 8x - 8 - 3x - 2 = 34 \\ - 11x - 10 = 34 \\ - 11x = 34 + 10 \\ - 11x = 44 \\ \frac{ - 11x}{ - 11} = \frac{ - 44}{ - 11} \\ x = -4 [/tex]

Margo had 8 feet of rope, . She cut the rope into 6 inch long strips. How many strips did Margo cut?
Answer:
The answer is 16
Step-by-step explanation:
So at first we need to convert 8 feet to inch.By doing so you will get 96.After that you need to divide the answer that is 96 by 6.Doing so you will get 16.
So basically the answer is 16.

===========================================================
Problem 62
T(n) = nth triangular number
T(n) = n(n+1)/2 = 0.5n(n+1)
That squares to (0.5n(n+1))^2 = 0.25n^2(n+1)^2
The next triangular number after T(n) is
T(n+1) = 0.5(n+1)(n+1+1) = 0.5(n+1)(n+2)
That squares to 0.25(n+1)^2(n+2)^2
Notice how each squared result has 0.25 and (n+1)^2 found buried in them.
Let's say A = 0.25(n+1)^2
That would mean the first result 0.25n^2(n+1)^2 becomes An^2
The second result 0.25(n+1)^2(n+2)^2 becomes A(n+2)^2
Let's add those to see what happens
An^2+A(n+2)^2
An^2+A(n^2+4n+4)
A(n^2+n^2+4n+4)
A(2n^2+4n+4)
0.25(n+1)^2*(2(n^2+2n+2))
0.5(n+1)^2(n^2+2n+1+1)
0.5(n+1)^2((n+1)^2+1)
0.5k(k+1)
We see that the result is a triangular number where k = (n+1)^2
This shows that adding the squares of consecutive triangular numbers gets us another triangular number.
A few examples
3^2+6^2 = 9+36 = 45 which is in the form n(n+1)/2 when n = 96^2+10^2 = 36+100 = 136 which is in the form n(n+1)/2 when n = 16Answer: Triangular number===========================================================
Problem 63
I'll borrow some of the ideas from problem 62
We found that after squaring the nth and (n+1)th triangular numbers, we got An^2 and A(n+2)^2 respectively. We let A = 0.5(n+1)^2
Subtract those expressions to get...
A(n+2)^2 - An^2
A(n^2+4n+4)-An^2
A(n^2+4n+4-n^2)
A(4n+4)
4A(n+1)
4*0.5(n+1)^2*(n+1)
(n+1)^3
This proves that the difference between the squares of consecutive triangular numbers is a perfect cube, aka a cube number.
A few examples:
6^2 - 3^2 = 36 - 9 = 27 = 3^310^2 - 6^2 = 100-36 = 64 = 4^3Answer: Cube number===========================================================

i need help algebra
Answer:
A. the slope value is 1/4
B. 0
C. y = 1/4x
Step-by-step explanation:
A: the slope can be calculated with the formula
[tex]m = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} [/tex]
m is the slope
(x1, y1) is your first coordinate point (any point will work)
(x2, y2) is your second coordinate point (any point will work)
Plug in your values, in this case I chose (0,0) and (4,1) as the two coordinates:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - 0}{4 - 0} = \frac{1}{4} [/tex]
B: the y-intercept is the y-coordinate of where the graph touches the y-axis and in this case the coordinate is (0,0) where the y coordinate is 0.
C:
the equation of the graph is y = mx + b.
m is the slope = 1/4
b is the y-intercept = 0
Therefore the equation is y = 1/4x
