A.) The y-intercept is 5 and the x-intercept is 4 cause that's where it intersects with the y and x axis.
b.) The slope is -5/4 cause it line is falling 5 down and 4 across (y/x).
c.) you use the slope intercept equation which is y=mx+b so the equation of the line would be y= -5/4x + 5 because m stands for the slope so you'd sub the number we'd already found which is -5/4. b stands for the y-intercept so you'd plug the number found previously as well which is 5.

Make m the subject of the formula m/v - t/b = m-t/r

RoseWind [281]

Answer:

$m = - \frac{ \frac{t}{b} + \frac{t}{r} }{1 - \frac{1}{v} }$

Step-by-step explanation:

$\frac{m}{v} - \frac{t}{b} = m - \frac{t}{r} \\ \frac{m}{v} - \frac{t}{b} + \frac{t}{r} = m \\ - \frac{t}{b} + \frac{t}{r} = m - \frac{m}{v} \\ - \frac{t}{b} + \frac{t}{r} = m(1 - \frac{1}{v} ) \\ - \frac{t}{b} + \frac{t}{r} = \frac{m( 1 - \frac{1}{v}) }{(1 - \frac{1}{v}) } \\ - \frac{ \frac{t}{b} + \frac{t}{r} }{1 - ( \frac{1}{v} ) } = m$

HELP PLS use the original price and markup to find the retail price. original price $68 markup 20%

insens350 [35]

Answer: $81.60

Step-by-step explanation:

When we have an original price OP, and a markup of X% (this is how much increases the price with respect to the original price)

The retail price will be:

RP = OP + (X%/100%)*OP

RP = OP*(1 + X%/100%)

In this case, we have:

Original price = OP = $68

markup = X% = 20%

Replacing these in the above equation, we get:

RP= $68*(1 + 20%/100%) = $68*(1 + 0.20)

RP = $68*(1.20) = $81.60

Then the retail price of this particular item is $81.60
