Answer:
Step-by-step explanation:
We want to find a quadratic that passes through the points:
In intercept form.
First, note that the first two given points are the <em>x</em>-intercepts of our quadratic. Intercept or factored form is given by:
Where <em>p</em> and <em>q</em> are the <em>x</em>-intercepts, and <em>a</em> is the leading coefficient.
So, we will substitute -4 and 2 for <em>p</em> and <em>q: </em>
Simplify:
Next, the third point (6, -20) tells us that <em>y</em> = -20 when <em>x</em> = 6. So:
Solve for <em>a: </em>
Thus:
Hence, our equation in intercept from is:
Answer:
$18.37
Step-by-step explanation:
$15.97 × 15%
$15.97 × 0.15 = 2.3955
$15.97 + $2.3955 = $18.3655 ≈ $18.37
Answer:
-3/5
Step-by-step explanation:
put down the 5,0 and 0,3 then simply start at the 5,0 and count up how many boxes it takes to get to the three then count left how many boxes it takes to get to 0 so...3/5. then look at the line. its going down which means it is negative. so the slope is -3/5
