Answer:
a. Not proportional
b. Proportional;
k = ⅞
Step-by-step explanation:
A proportional relationship is usually represented in the format, y = kx. k here represents constant of proportionality. This shows that x and y are directly proportional.
a. y = -2x + 9 is not a proportional equation.
b. y = ⅞x is a proportional equation.
Constant of proportionality: k = ⅞
Answer:
6654.54
Step-by-step explanation:
you divide 12000 by 11 and times 6.1
Step-by-step explanation:
The correct steps are:
2x²-2x-24=0
2(x²-x-12)=0
2(x-4)(x+3)=0
x=4 or x=-3
so what actually went wrong, is the final answer which is supposed to be <em>x=4,-3</em><em> </em>instead of x=-4,3
Answer:
(-infinity,+infinity)
Step-by-step explanation:
Domain refers to the x-axis. So if we look from left to right along the x-axis we could conclude that the function will go infinitley from negative infinite to positive infinity.
