Because even though 'a' and 'b' are rational, and their squares are
also rational, that doesn't guarantee that the sum of their squares
has a rational square root.
Examples:
1 and 2
Sum of squares = 5
√5 is irrational
2 and 3
Sum of squares = 13
√13 is irrational
4 and 5
Sum of squares is 41
√41 is irrational
'c' is rational only when 'a', 'b', and 'c' form a . . . . . wait for it . . . . .
a 'Pythagorean triple'.
Examples:
3 and 4
Sum of squares is 25
√25 = 5 is rational yay
5 and 12
Sum of squares is 169
√169 = 13 is rational yay
Answer:
They are parallel but they are not equal where y=7x^2 It's y intercept is 0 and for y=7x^2+4 it's y intercept is 4
Step-by-step explanation:
Answer:
x>-4
Step-by-step explanation:
-8x<32 - First isolate the x by dividing both sides by -8
-8x/-8<32/-8
x>-4

It’s 8/15 decimal form it’ll be 0.53 hope this helped !
Answer:
y>=1*x+2
Step-by-step explanation:
y>=k*x+n
we know that 2=k+n and 0=-2k+n
so 4=2k+n and 0=-2k+n
now 4=2n so n=2
now k=1
so y>=1*x+2
