same process as before part I: find the y-intercept by letting x = 0
y=-7
awesome, so part A = (0,-7) for part B find x = -b/(2a)
-3/4
that is part II right?
it is asking for both x and y so you must also find the y-coordinate by substituting x = -(3/4) into the equation
y=-65/8
good, that's it for p II for part III simply plug in a b and c into the quadratic eqn
what is the equation again
|dw:1515018859417:dw|
x=5.06/4
there should be two solutions express them in decimals rounded to the nearest 10th
1.23
good, what about the other solution?
-1.23
in exact form your answer should have been -(3/4) +/- sqrt(65)/4 convert this to a decimal form. remember that +/- means you must consider the plus sign and negative sign answers
3.28
-(3/4) - sqrt(65)/4 = ?
-4.78
oh okay, I see what I did wrong.
i put the sqrt over the entire 65/4
when it is suppsed to be only on the 65
1.27 and -2.77 = your answers
was just about to say that
thanks !!
