Does the point (0, 0) satisfy the equation y = 9x?

Mathematics
1 answer:
miskamm [114]2 years ago
6 0

Answer:

yes it does

Step-by-step explanation:

because the equation y=9x does not have a y-intercept (all slopes come in the form y=mx+b -- it can be written differently though) and since there is no 'b' that means the y-intercept is 0. So whenever there is no y-intercept, the slope starts at 0.

Which of the following linear equations describes that relationship?
JulsSmile [24]

Answer:

  • D. f(x) = 4x - 3

Step-by-step explanation:

<u>Use two pairs of points to work out the equation: </u>

  • (1, 1) and (2, 5)

<u>Find the slope:</u>

  • m = (5 - 1) / (2 - 1) = 4/1 = 4

<u>Find the y-intercept:</u>

  • 1 = 4*1 + b
  • b = 1 - 4
  • b = - 3

<u>The line is:</u>

  • f(x) = 4x - 3

Correct choice is D

If $190 is invested at an interest rate of 11% per year and is compounded continuously, how much will the investment be worth in
dangina [55]

Answer:

$295.01

Step-by-step explanation:

Using the compounding continuously formula, we are looking for A.  We have that P = 190; r = .11 (always use the decimal form of the rate!); and t = 4.  Filling in we have:

A=190e^{(.11)(4)}

Simplifying that multiplication:

A=190e^{.44}.

On your calculator, raise e to the .44 power to get

A = 190(1.552707219) and

A = $295.01
