Answer:
Excluded Value : 3 and -5
Step-by-step explanation:
hello :
Excluded Value : and
the excluded value when : x²+2x-15=0
(
x²+2x+1)-1-15=0
means : (x+1)²-16=0 (x+1)²-4² = 0
by identity : a²-b² =(a-b)(a+b)
(x+1-4)(x+1+4) =0 so : (x-3)(x+5) =0 means : x-3=0 or x+5=0
x=3 or x= -5
Excluded Value : 3 and -5
Answer:
a)
x/25 = 7/2 --> x = 25 * 7/2 = 87.5 miles
b)
x = 45/75 = 0.6 = 60%
c)
x = 1/(1/24 + 1/30) = 13 1/3 minutes
d)
x/2 + x/6 = 12 --> x = 18
4x - (9 - 3x) = 8x - 1
4x - (9) - -(3x) = 8x - 1
4x - 9 + 3x = 8x - 1
7x - 9 = 8x - 1 (-8x from each side)
-x - 9 = -1 (+9 to each)
-x = 8 (divide -1 from each side)
x = -8
Answer:
$ 1.50 x 25= 37.50
