2.25
Step-by-step explanation:
divide
Answer:
y = 4x - 25
Step-by-step explanation:
y = 4x + b
-1 = 4(6) + b
-1 = 24 + b
-25 = b
Answer:
1500
Step-by-step explanation:
we can write the 4-digit PIN as ABCD
A = factor of 10 so,
A = 1, 2 ,5 (3 possible number or we can write n(A) = 3
B and C are number from 0 - 9 so each have 10 possible number n(B) = 10 and n(C) = 10
D makes the whole number cannbe divide by 2. it means that D must even number 2,4,6,8 or 0. so there are 5 possible number n(D) = 5
so to find how many different sets we just multiply all possible number
n(A) x n(B) x n(C) x n(D)
3 x 10 x 10 x 5 = 1500 different sets
A. an exponent that’s divided, the denominator will always be the root, and the numerator will be what it’s multiplied by
Step-by-step explanation:
Consider the variables a and b, whereas a is an odd integer and b is an even integer.
By definition: a = 2x + 1 and b = 2y (values for which x;y are integers)
The summation of a and be would be: a + b = 2x + 2y + 1
Simplifying the equation: 2x + 2y + 1
=2(x + y) + 1
=2m + 1 (values for which m = x + y is an integer)
Therefore by definition of an odd integer (2x + 1), it is clear that the sum of an odd integer and an even integer is odd.
