12) 2×2×2×2×2
14)(3/5) write it 4 times
16)2×2×2×5×5 and the rest I'm not sure but you should try using photomath :) it gives u the answers and the work!
A proportional relationship is described by the equation
... y = k·x
The point (x, y) = (0, 0) is <em>always</em> a solution to this equation.
_____
In short, if the relationship is proportional, its graph will go through the origin. If the graph does not go through the origin, the relationship is not proportional.
___
Note that this is true if the domain includes the origin. You can have y = kx <em>for x > 10 </em>and the graph will <em>not</em> go through the origin because the function is <em>not defined</em> there.
Answer:
4096
Step-by-step explanation:
£150. Since €1.2=£1, you would do 180 divided by 1.2 to find out how many £.
Answer:
x = 4
Step-by-step explanation:
f(x)= 3x-1
f(2)= (3×2)-1
f(2)= 6 - 1
f(2)= 5
Now,
g(x) = f(2)
2x-3 = 5
2x = 8
x = 4
