Answer: 15
Step-by-step explanation: First you start by adding 2+3=5 then you multiply 5 x 3 which equals 15
Answer:
As x increases , y decreases then increases
Step-by-step explanation:
There are two situation
1> when x < 0
2> when x>= 0
let see
when x < 0
we see that as value of x moves from -ve value towards zero (i.e x is increasing) then value of y is decreasing( value of x has moved from positive side of y( above x-axis) towards negative side of (below x-axis)\
Thus, we can say that
for x < 0
As x increases , y decreases
________________________________________
when x>= 0
we see that as value of x moves from 0 towards +ve value(i.e x is increasing) then value of y is increasing( value of x has moved from negative side of y( below x-axis) towards positive side of (above x-axis)\
Thus, we can say that
for x >= 0
As x increases , y increases
_________________________________________
combining both observation it can be said that
As x increases , y decreases then increases which is equal to fouth option
Answer:
1 1/3 more minutes
Step-by-step explanation:
Lets first convert both times to improper fractions
7 1/2 -> 15/2 (Mark's Time)
6 1/6 -> 37/6 (Mark's Brother's Time)
Now we need common denominators
15/2 = 45/6
Now times to subtract Mark's time - Mark's Brother's Time = More Time
45/6 - 37/6 = 8/6 or 1 2/6 = 1 1/3
Answer:
the answer is 1/9 in decimal for 0.1
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Subtracting the given expressions, that is
3b² - 8 - (b(b² + b - 7) ) ← simplify parenthesis
= 3b² - 8 - (b³ + b² - 7b) ← distribute parenthesis by - 1
= 3b² - 8 - b³ - b² + 7b ← collect like terms
= - b³ + 2b² + 7b - 8 ← substitute b = - 3
= - (- 3)³ + 2(- 3)² + 7(- 3) - 8
= - (- 27) + 2(9) - 21 - 8
= 27 + 18 - 21 - 8
= 16
