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
5% of 11 is 0.55. What number times 0.55 = 11? Well if we divide 11 by 0.55, we see that the answer is 20. So, the population will double in 20 years. If the population is 22 in 20, it stands to reason that it will take another 20 years to double from 22 to 44. So, the population will reach 44 in 40 years.
Hope this helps.
Answer:
y = - x + 4
Step-by-step explanation:
Use point-slope form: y-k = m(x-h) for point (h,k) with slope m
now just plug and chug:
y-4 = -1(x-0)
y-4 = -x
y= -x+4
not sure about what you meant by "solution." Just gonna assume that you were looking for the equation.
