Answer:

unit rate: \frac{1}{8}  .....main answer.

equation: y = \frac{x}{8} .......use it to find any given points.

<u>Explanation</u>:

Take two comfortable best coordinates: ( 1 , 1/8 ) , ( 2 , 2/8 )

<u>slope</u>:

\frac{y2-y1}{x2-x1}

\frac{\frac{2}{8} -\frac{1}{8} }{2-1}

\frac{1}{8} ...this is the slope and the unit rate of the situation(m)

<u>Equation</u>:

y - y1 = m( x - x1 )

y - 1/8 = \frac{1}{8}( x - 1 )

y = x/8  .....equation.

HELP!
Korolek [52]

Answer:

<u>Algebraically</u>

0.5x-7= √(-5x+29)

(0.5x-7)² = -5x+29

(0.5x)² - 2*0.5x*7 + 7² = -5x+29

0.25x² - 7x + 49 + 5x - 29 = 0

0.25x² - 2x + 20 = 0

Its discriminant is:

b² - 4*a*c

(-2)² - 4*0.25*20

-16 < 0

Therefore, the equation has no solutions.

<u>Graphically</u>

In the picture attached, the plots of the functions are shown. We can see that they don't intersect each other, and that is why there is no solution.

This math I just can't figure out
Elena-2011 [213]

Step-by-step explanation:

Here's the first question and how to solve the second.

So the first business start with 250, that's your b in slope.

y = mx + b

y = mx + 250

Now, they charge 14 an hour so that's your m.

y = 14x + 250

x is the number of hours it takes.

The second business is straight up 22 per hour, so it's just y = mx, where b is 0.

y = 22x VS y = 14x + 250

Try plugging in different numbers and seeing how much it take to level out!

5000, take 3500 multiplied by 2/7 to find the amount of money deposited per month which is 1000 then multiply it by 5 to find the deposit over 5 months
