Answer:

3.b

(\frac{8}{3})^{2x+1} *(\frac{8}{3})^{5} =(\frac{8}{3}) ^{x+2}\\\\(\frac{8}{3})^{2x+1 +5} =(\frac{8}{3}) ^{x+2}\\\\\\2x +6 = x+2\\x = -4

i hope question 3.a. is 5^x ÷ 5^-3 = 5^5

3.a.

\frac{5^x}{5^{-3}} = 5^5\\\\5^ {x+3} = 5^5\\\\x+3 = 5\\x =2

12(6k+3)+4(7-5k) the distributive property simply each expression
hodyreva [135]
The distributive property: a(b + c) = ab + ac

12(6k + 3) + 4(7 - 5k) = 12(6k) + 12(3) + 4(7) + 4(-5k)

= 72k + 36 + 28 - 20k = 52k + 64

Which equation represents a line parallel to the line shown on the graph? On a coordinate plane, a line goes through (negative 6
ELEN [110]

Answer:

\boxed{ \mathrm{y = \ negative \  3 x + 3}}

Step-by-step explanation:

The coordinates are (-6,0) and (-8,6)

<u><em>Finding slope of the line</em></u>

Slope = \frac{rise}{run} = \frac{y2-y1}{x2-x1}

Slope = \frac{6-0}{-8+6}

Slope =\frac{6}{-2}

Slope = -3

Parallel lines have equal slopes.

So, the line which is parallel to this line is y = negative 3 x + 3
