Answer:
288
Step-by-step explanation:
a = 9
b = -1
c = -8
b^2 * -4 * ( a * c )
Just filing in the numbers given above:
-1^2 * -4 * ( 9 * -8 )
1 * -4 * ( -72)
1 * + 288 = 288
That would be 57 because .85 rounds up to one more place.
Answer:
y = -1/4 x + 15.
Step-by-step explanation:
y = 4x - 2 has a slope of 4 ( = the coefficient of x).
The line at right angles to it will therefore of a slope of -1/4.
Using the point-slope form of a line the line t which passes through (4, 14) is found as follows:
y - 14 = -1/4(x - 4)
y = -1/4x + 1 + 14
y = -1/4x + 15
