Answer:

b =-6

Step-by-step explanation:

$(y^{b})^4=\frac{1}{y^{24}} \\\\y^{4b}=y^{-24}\\4b = -24\\b=\frac{-24}{4}\\b =-6$

(72*78*85*90*90)/(68*84*91*108) (There's an easier way than multiplying out the giant products 72 78 85 90 98 and 68 84 91 108)H

Sveta_85 [38]

Cancel common factors. For instance,

$\dfrac{72}{68}=\dfrac{2^3\cdot3^2}{2^2\cdot17}=\dfrac{2\cdot3^2}{17}=\dfrac{18}{17}$

For this expression, we have

$\dfrac{72\cdot78\cdot85\cdot90^2}{68\cdot84\cdot91\cdot108}=\dfrac{2^6\cdot3^7\cdot5^3\cdot13\cdot17}{2^6\cdot3^4\cdot7^2\cdot13\cdot17}=\dfrac{3^3\cdot5^3}{7^2}=\dfrac{15^3}{7^2}=\dfrac{3375}{49}$

If f(x) = 3^2 + 10x and g(x) = 2x-4, find (f-g)(x).

Marat540 [252]

What we know:

$f(x)=3^2+10x\\g(x)=2x-4$

(Also, $3^2=9$ )

What we need to solve:

$(f-g)(x)$ (This is equal to $f(x)-g(x)$ )

How you have to subtract $f(x)$ with $g(x)$ to get:

$(f-g)(x) = f(x)-g(x) = 9+10x+2x-4 = 12x+5$

Thus, the answer would be:

$12x+5$

Graph each of the following lines without using a table of values a. y = 2⁄3x - 5 b. 6x - 2y + 5 = 0

DedPeter [7]

$\text{Graph the lines:}\\\\a. \,\,y = 2/3x - 5\\\\\text{For this equation, we are given our beginning point and slope}\\\\\text{The beginning point is -5, so you would put a point at -5 on the y-axis}\\\\\text{Since the slope is 2/3, we would use the rise/run method}\\\\\text{In this case, starting from -5 on the y-axis, you would go up 2 and to the}\\\text{right 3, then place your point where you ended up.}\\\\\text{Keep using the rise/run method to create the rest of the points}\\\\$

$b.\,\, 6x - 2y + 5 = 0\\\\\text{Turn the equation into slope form:}\\\\ 6x - 2y + 5 = 0\\\\-2y=-6x-5\\\\y=3x+5/2\\\\\text{The beginning point is at 5/2, or 2.5}\\\\\text{Place the point at 2.5 on the y-axis}\\\\$

$\text{We know the slope is 3, so use the rise/run method. In this case, you}\\\text{will go up 3 and 1. Continue this process}$

$\text{I hope this helps, have a good day.}$
