Tell me if it is right.
Let the numbers be x and y. Then xy = -30 and x+y = -3.
Solve xy = -30 for y: y = -30/x
subst. -30/x for y in x+y= -3: x - 30/x = -3
Multiply all 3 terms by x: x^2 - 30 = -3x, so x^2 + 3x - 10 = 0
Solve this quadratic equation for x. x: {-5, 2}
If x = -5, then x+y = -3 becomes -5 + y = -3, and y = 2.
You should check to determine whether x=2 is also correct. If it is, what is the corresponding y value?
Answer:
X = 4
Step-by-step explanation:
3x=16-4
3x= 12
X=12/3
X= 4
-x intercepts: 5, -2
-1/2(x-5)(x+2) is wider than the first equation because the coefficient is smaller
Answer:
Susie rounded to the nearest thousandth.
Step-by-step explanation:
since the 100th place is 0 it would round down to 39,000 when you are rounding to the nearest thousand.
