Standard form is x + y = number
The equation has a slope of 3 and a y intercept of -4 so the equation should be
y = 3x - 4
To get this in standard form you have to move the 3x to the other side.
y - 3x = -4
-3x + y = -4
The coefficient before x cannot be negative in standard form so you have to multiply the whole equation by -1.
3x - y = 4

Zara has forgotten her 4-digit PIN code.
lbvjy [14]

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

6. Proof by generalization from generic particular that the sum of an odd integer and an even integer is odd. (3 marks)
andreyandreev [35.5K]

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.
