Answer:

a = - 45

b = 15

Step-by-step explanation:

The 1st number is a, and the 2nd is b.

ab=225 (1)

a+b=-30 (2)

(2) <=> a = -30 - b

Replace a with -30 - b in (1):

(-30-b)b = 225

<=> -b^2 + 30b = 225

<=> b^2 - 30b + 225 = 0

<=> b^2 - 2.15.b + 15^2 = 0

<=> (b-15)^2 = 0

=> b = 15

a = -30 - b = - 30 - 15 = - 45

Find the missing value so<br> that the two points have a<br> slope of -13/2 (-2,y) and (0,-4
Art [367]

Answer:

y=9

Step-by-step explanation:

slope is (y2-y1)/(x2-x1), so we plug in the values. (-4-y)/(0 - (-2)). so we get -4-y/2 since zero minus negative 2 is positive 2. given the slope is -13/2, -4-y must be equal to negative 13. So we set an equation of -13 = -4 - y. We add 4 to 13, and get -9 = -y. We multiply each side by a -1, and we get y equals 9.

We can check this by plugging 9 back into our original slope equation. (-4-9)/(0-(-2) which gives us -13/2.
