Answer: Choice C) y = 2x

The line goes through the origin, so the y intercept is b = 0

The slope is rise/run = 2/1 = 2 because we go up 2 units for every unit we go to the right. This is why m = 2.

Plug m = 2 and b = 0 into the slope intercept form to go from y = mx+b to y = 2x+0, which is the same as y = 2x.

Write an equation in slop-intercept form the line with slope 1/4 and y-intercept -7
Licemer1 [7]

When you write an equation in the slope-intercept form

y=mx+b

the two coefficients m and b represent, respectively, the slope and the intercept.

So, in your case, m=1/4 and b= -7, which leads to the equation

y=\dfrac{1}{4}x-7

A video game system and several games are sold for $700. The cost of the games is three times as much as cost of the system. Fin
soldier1979 [14.2K]

Answer:

cost of system is $175 and cost of the games is $525

Step-by-step explanation:

Let us take the cost of the system to be X.The games cost 3 times as much as the system and are therefore given 3X. The total cost of the system and the games is $700.Therefore,we form the equation 3X+X=$700.Meaning that 4X=$700 and X is equal to $175.The cost of the system is X therefore it is $175 and the cost of the games is 3X and is therefore $525.

What is the inverse of f(x)=2^x
GuDViN [60]

Answer:

<h2>{f}^{ - 1} (x) =  \frac{ln(x)}{ln(2)}</h2>

Step-by-step explanation:

f(x)=2^x

y =  {2}^{x}

x =  {2}^{y}

{2}^{y}  = x

ln( {2}^{y} )=ln(x)

yln(2)=ln(x)

<h3>\frac{yln(2)}{ln(2)}  =  \frac{ln(x)}{ln(2)}</h3><h3>y =  \frac{ln(x)}{ln(2)}</h3><h3>{f}^{ - 1} (x) =  \frac{ln(x)}{ln(2)}</h3><h3>Hope it is helpful...</h3>
