Answer:

  D)  bx - a

Step-by-step explanation:

If a/b is a zero, then (x -a/b) is a factor of the polynomial. That is, the value x=a/b will make a factor of the polynomial be zero.

The above factor can be written without fractions by multiplying it by b:

  (bx -a) . . . . matches choice D

__

You can also choose the answer on the basis of which expression becomes zero when x=a/b.

If two angles are complementary then both angles must be acute true or false
Oxana [17]

Answer:

If two angles are acute angles, then they are complementary. Incorrect. The converse is “If two angles are complementary, then they are acute angles” which is true and the original statement was false because two acute angles are not always complementary.

The population of kansas city, missouri was 435,000 in 1990 and 482,300 in 2005. if the population is changing linearly, write a
Jlenok [28]
Find the slope of the line connecting (1990,435000) and (2005,482300):

        482300-435000        47300
m = ----------------------- = ---------------- = 3153/yr (approx)
          2005 - 1990                15 yr

Use the point-slope formula to find the equation of this str. line:

y-435000 = (3153/yr)(x-1990)

The year 2020 is 30 years after 1990.  Thus, the expected pop in 2020 is

given by     y-435000 = 3153(30) = 94590, so that y = 529590.

One of Eric's steps is 18in long. How many steps would he take to walk 1 mile?
Evgesh-ka [11]

Answer:

3520 steps

Step-by-step explanation:

The first thing we must do is figure out how many inches are in a mile. (There are 63,360 inches in one mile). With that out of the way, we can now divide these inches by 18, since each of Eric's steps are 18 inches long, and we want to determine how many steps he would have to take. 63,360 divided by 18 is 3520. This means our answer is 3520 steps, and that is how many steps he must take to walk 1 mile. I hope you understood and please let me know if you still need help!
