Step-by-step explanation:
Non examples are:
y= 1/2 x - 3
y = x - 2
x = 6y
Examples are:
5x - 3y = 9
2x + 3y = 0
x + y = 1
Answer:
fourth option
Step-by-step explanation:
Given
= 
( cross- multiply )
y(w + 2) = 2z(2x - 1) = 4xz - 2z ( divide both sides by y )
w + 2 = 
( subtract 2 from both sides )
w = - 2
Answer:
a = -5
Step-by-step explanation:
If it starts at 5 degrees celsius and raises to 15 degrees celsius in 3 minutes it increases by about 3 1/3 every minute.
times that by 5 and you get 16 2/3. times that by 10 and you get 33 1/3
The Pythagorean Theorem states that a^2+b^2=c^2
We already have:
A^2+6^2=117
All we need to do is find the missing A by subtract b from c.
117-36=81
Now the square root of 81, 9.
So, x is 9 cm.
