4^0 * 4^2 * 4^2 /4^2

=4^(0+2+2 - 2)

=4*2

= 16

----------------------------------------

66)

(2^3)^-3

= 2^(3 *(-3))

= 2^-9

= 1 / 2^9

------------------

76)

(3^-1)^^4

= 3^(-1 * 4)

= 3^-4

= 1 / 3^4

86)

(2^2)^-4 * 2^2 ^ 2^0

= (2^-8) * 2^2 * 1

= 2^(-8 + 2)

= 2^-6

= 1 / 2^6

Graph the system of inequalities y> 2x-3 and 3y-x≤6

Veronika [31]

Y > 2x - 3
3y - x ≤ 6
 ↓
y = 2x - 3
3y - x = 6

 3(2x - 3) - x = 6
3(2x) - 3(3) - x = 6
 6x - 9 - x = 6
 6x - x - 9 = 6
 5x - 9 = 6
 + 9 + 9
 5x = 15
 5 5
 x = 3
y = 2x - 3
y = 2(3) - 3
y = 6 - 3
y = 3
(x, y) = (3, 3)

dybincka [34]

Answer:

<h3>Solution:-</h3>

Let

Tinky's age=x

Laa's age=x+2

According to the question

$\qquad\quad {:}\longmapsto\sf 5 (x+x+2)-1=x (x+2)$

$\qquad\quad {:}\longmapsto\sf 5(2x+2)-1=x^2+2x$

$\qquad\quad {:}\longmapsto\sf 10x+5-1=x^2+2x$

$\qquad\quad {:}\longmapsto\sf 10x+4=x^2+2x$

$\qquad\quad {:}\longmapsto\sf 10x-2x+4=x^2$

$\qquad\quad {:}\longmapsto\sf x^2=8x+4$

$\qquad\quad {:}\longmapsto\sf x^2-8x-4=0$

Can someone please help me with 13 and 14, please show work, thx :)

Shalnov [3]

13.
1st: split the 1 shape into 2 shapes. (spit across to where you see one right angle(top), and a trapezoid(bottom)

2nd: now what i did was fill that gap to where the total height is 9 and the total length is 7. ( if you don't want to do that it is fine )

3rd: for the top do 5 times 2 = 10

4th: for the bottom do 4 times 5 = 20

5th: add 10 (top) and 20 (bottom) = 30
