Answer:
-1 and -2, or 9 and 10
Step-by-step explanation:
If x is the smaller integer:
x (x + 1) = 14 + 4 (x + x + 1)
x² + x = 14 + 4 (2x + 1)
x² + x = 14 + 8x + 4
x² − 7x − 18 = 0
Factor using AC method:
(x − 9) (x + 2) = 0
x = -2 or 9
x is the smaller integer, so the larger integers are -1 and 10. Check each pair of solutions.
-1 and -2:
(-2) (-1) = 14 + 4 (-2 + -1)
2 = 14 + 4 (-3)
2 = 2
9 and 10:
(9) (10) = 14 + 4 (9 + 10)
90 = 14 + 4 (19)
90 = 90
Both solutions work.
1 - ( 2/3 + 1 /4 ) =
= 1 - ( 8 / 12 + 3 / 12 ) =
= 1 - 11 / 12 = 12 / 12 - 11 /12 = 1 /12
Answer:
1 / 12 of the girls in class have neither blue or brown eyes.
Standard form:
Y - 0= 1(x - 1)
Y - 0= x - 1
-x+y= -1
- (-x+y= -1)
Answer:
x-y=1
Slope-Intercept form:
Y - 0= 1(x-1)
Y - 0 = x - 1
Answer:
Y= x-1
S = P[1 + (r / m)]^(m * t)
S = ?
P = 6000 euro
r = 0.07
m = 12
t = 5
S = 6000[1 + (0.07 / 12)]^(12 * 5)
S = 6000(1.00583)^(60)
S = 6000(1.4176...)
<span>S = 8505.75 euro
