Answer:
15x = -75
x = -5
Step-by-step explanation:
Set the first part about the product of 15 and x equal to -75.
Then, divide both sides by -15 to get y = -5.
Answer:
c
Step-by-step explanation:
Factor : x^2+3x-10
Answer = (x - 2)(x + 5)
Explanation:
Y = x^2 + 3x - 10.
Find 2 numbers knowing sum (3) and product (-10).
Factor pairs of (-10) -> (-1, 10)(-2, 5). This sum is 3 = b. The 2 numbers are: -2 and 5.
y = (x - 2)(x + 5).
By finding like denominators, you can add the fractions on each side. Then, compare by cross multiplying.
Answer: 2.15, 2.2, 2.2012, 2.501
