Answer: i guess the problem is with P(x) => "x =
", then P(x) is true if that equality is true, and is false if the equality is false.
so lets see case for case.
a) x = 0, and
= 0. So p(0) is true.
b) x = 1 and
= 1, so P(1) is true.
c) x = 2, and
= 4, and 2 ≠ 4, then P(2) is false.
d) x= -1 and
= 1, and 1 ≠ -1, so P(-1) is false.
2, (double) 4, (double) 8 (double) 16, So 16 in week 4
2+4+8+16 = 30
Answer:
1/16
Step-by-step explanation:
Both 5 and 80 can be divided by 5.
This reduces the ratio of 5/80 to 1/16.
Answer:
xy = 1
k = 79
Step-by-step explanation:
Question One
The first and third frames look to me to be the same. I'll treat them that way.
y = x^2 Equate y = x^2 to the result of 2y + 6 = 2x + 6
2y + 6 = 2(x + 3) Remove the brackets
2y + 6 = 2x + 6 Subtract 6 from both sides
2y = 2x Divide by 2
y = x
Now solve these two equations.
so x^2 = x
x > 0
1 solution is x = 0 from which y = 0. This won't work. x must be greater than 0. So the other is
x(x) = x Divide both sides by x
x = 1
y = x^2 Put x = 1 into x^2
y = 1^2 Solve
y = 1
The second solution is
(1,1)
xy = 1*1
xy = 1
Answer: A
Question Two
square root(k + 2) - x = 0
Subtract x from both sides
sqrt(k + 2) = x Square both sides
k + 2 = x^2 Let x = 9
k + 2 = 9^2 Square 9
k + 2 = 81
k = 81 - 2
k = 79
