Answer:
2
Step-by-step explanation:
To find the answer we just need to reverse the operation. So to find the cubic root of 8.
That equals 2 since 2*2*2=8
Factors of 25: 5 x 5; sum = 10
Factors of 26 : 2 x 13; sum = 15
Factors of 27: 3 x 3 x 3; sum = 9
Highest sum is for the factors of 26. Thus, you should choose the number 26.
Answer:
k = 2/3 x
y = 2/3.
Step-by-step explanation:
y = kx where k is a constant
y = 2 when x = 3 so:
2 =k*3
k = 2/3.
The equation is y = 2/3 x.
When x = 1
y = 2/3 * 1 = 2/3.
Answer:
(5, - 2)
Step-by-step explanation:
2x+y>3
x-y>1
2x + y > 3 - - - - (1)
x - y > 1 - - - (2)
Using trial and error method :
Using :
(5,-2)
2x + y > 3
2(5) + (-2) > 3
10 - 2 > 3
8 > 3 (true)
x - y > 1
5 - (-2) >1
5 + 2 > 1
7 > 1 (True)
For 0,5
2x + y > 3
2(0) + (5) > 3
0 + 5 > 3
5 > 3 (true)
x - y > 1
0 - (5) >1
-5 > 1
--5 > 1 (false)
Also, all other options do not hold true for bitb inequality statements, hence answer is (5, - 2)
