Evaluate the expression when x=-2 and y=3 3x-4y​
Illusion [34]

The expression re-written: 3(2) - 4(3)

First, we multiply (PEMDAS)

3 * 2 = 6

4 * 3 = 12

6 - 12 = -6

Manny bought a brand new car in 2012 for $28,750. If the car depreciates by 12% each year, write an exponential function to mode
patriot [66]
The exponential formula for this situtation will be given by:
f(x)=ae^(-bx)
where:
a=initial price
b=rate
x=time in years
hence the formula will be:
f(x)=28750e^(-0.12x)
thus the value of the car in 2018 will be:
x=2018-2012=6 years
thus
f(6)=28750e^(-0.12*6)
f(6)=$13,994.13

Identify the slope and y-intercept of each of the following lines. Then graph each line.
viktelen [127]

First <u>rewrite the equation</u> in slope intercept form

slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]

\rightarrow \sf 8y = -2x+32

\rightarrow \sf y =\dfrac{ -2x+32}{ 8}

\rightarrow \sf y =\dfrac{ -2x}{ 8} + \dfrac{32}{8}

\rightarrow \sf y =\dfrac{ -1}{ 4}x + 4

<u>comparing</u> with y = mx + b

  • slope: -1/4     and   y-intercept: 4

x-intercept:          ( then y will be 0 )

\hookrightarrow  \sf -2x + 32 = 0

\hookrightarrow  \sf -2x  = -32

\hookrightarrow  \sf x  = 16

In order to graph the line

  • plot x = 16 on the x-axis     coordinate: (16, 0)
  • plot y = 4 on the y-axis     coordinate: (0, 4)
  • Then using a scale/ruler draw a straight line through this points.
