Answer:

A

Step-by-step explanation:

Because 1/3 if divide into two, it'll be 0.5/3 but if the question says that the answer have to be in whole number, that means it must be 1/6.

A town has a population of 18000 and grows at 2% every year. To the nearest tenth of a year, how long will it be until the popul
8090 [49]

Answer:

19.9

Step-by-step explanation:

we can write the following equation

18000(1.02)^n

where n is the number of years

so we have

26700=18000(1.02)^n

solve for n

1.483=1.02^n

use logs to solve for n

n=19.9

Answer:

  • 4
  • 2

Step-by-step explanation:

  = x²(-3 +5) +y²(2 -3) +5xy -2y

  = 2x² -y² +5xy -2y

a) there are 4 terms in the simplified expression

b) 2 terms have negative coefficients (-y² and -2y)

The vertex of this parabola is at (-4,-1). When the y-value is 0, the xvalue is 2
yaroslaw [1]
The standard form for this parabola is x = a(y-k)^2 + h because this is a sideways-opening parabola. Our h and k values for the vertex are (-4, -1). And it goes through (2,0). We just need to solve for the a. Filling in accordingly, 2 = a(0+1)^2-4 so 2 = a - 4. a = 6. A above.

correct answer is 6!

What is the slope of y = 1 + 5?
IgorLugansk [536]

Step-by-step explanation:

if there is no typo, then that is

y = 1 + 5 = 6

y = 6

has no term in x.

that means 6 is the constant result of the line function, no matter what x value we pick.

and that means this is a horizontal line (parallel to the x-axis) going through the point y=6 or (0, 6).

remember that the slope is the ratio "y coordinate change / x coordinate change".

but y is not changing at all, the change or difference is always 0 no matter what points we pick on the line.

and so, the slope ratio is always "0/...". and that is 0.

so, the slope of that line is 0.

but if there is a typo, then please know : the slope of a line

y =ax + b

is always a (the factor of x).
