If 2/5 were used wouldn't it make sense that 3/5 were unused

Answer:

150

Step-by-step explanation:

So, 300 divided by 2/5 = 750.

When you simplify:

750 - 300 = 450 (NOT DONE YET!)

450 - 300 = 150

150 is the most simplified answer.\

kotykmax [81]

Answer:

  -5t^2 +2t -3

Step-by-step explanation:

Collect terms in the sum:

  G+P = (3t^2 -5t +6) +(-8t^2 +7t -9) = (3-8)t^2 +(-5+7)t +(6-9)

  = -5t^2 +2t -3

What is the function rule for the line?
11Alexandr11 [23.1K]
So with these equations we need to find the y-intercept and the slope because:

y = mx+b

y = f(×)

b = y-intercept

m = slope (slope = rise/run, rise over run)

rise is y-axis
run is x-axis

The y-intercept is (0,-2)
So now we know that one of the answers must have -2 in it

b = -2

m= rise/run = -2/3

The answer is:

f(x) = - \frac{2 }{3 } x - 2

I need with these problems
ch4aika [34]

Answer:

1. \frac{5}{6}

3. \frac{7}{0} (undefined slope)

5. -\frac{7}{4}

7. 24

Step-by-step explanation:

slope (m)

rate of change (r)

1. m = \frac{y_2-y_1}{x_2-x_1}=\frac{8-3}{13-7} =\frac{5}{6}

3. m = \frac{y_2-y_1}{x_2-x_1}=\frac{4-(-3)}{9-9} =\frac{7}{0} (undefined slope)

5. m = \frac{y_2-y_1}{x_2-x_1}=\frac{-1-6}{0-(-4)} =\frac{-7}{4}=-\frac{7}{4}

7. r = \frac{f(b)-f(a)}{b-a}=\frac{24-0}{1-0}=\frac{24}{1}=24

Hope this helps!
