In a certain year the price of gasoline rose by 20% during January, fell by 20% during February, rose by 25% in March, and fell
zavuch27 [327]

Answer:

Fell by 25%

Step-by-step explanation:

+20% January

-20% February (20-20 is zero, so we're back to the original price we started at here)

+25% March

?? April

Currently, we are 25% more than what we had, so to get back to normal, the price needs to go down by 25 percent. This will put us back to zero. Put another way...

+20%-20%+25%-25%=0% (Original Price)

What is the slope intercept from for 16x+9y=40
Doss [256]

Answer:

y =  (- \frac{16}{9})x +  \frac{40}{9}is the slope intercept form for 16x+9y=40

Step-by-step explanation:

Here, the given equation is 16 x +  9 y = 40

Now, the slope intercept form of an equation is y = mx + c,

here m = slope of the equation,  b  =  y - intercept

So, now 16x +  9y = 40 on simplification gives

9y  = 40 - 16x

or y = \frac{40 - 16x}{9}  = \frac{40}{9}   - \frac{16x}{9}

or, y =  (- \frac{16}{9})x +  \frac{40}{9}is the slope intercept form of the given equation.

Here, m = (-16/9) and y- intercept = 40/9
