Find the equation of the line with slope m=1/2 that contains the point (4,6)
vazorg [7]

Answer:

y = 1/2x + 4

Step-by-step explanation:

Use the formula for the equation of a line.

y = mx + b

Where m is the slope, and b is the y-intercept.

The slope is given.

y = 1/2x + b

The points (x, y) are given.

(4, 6)

Put y as 6 and x as 4, solve for b.

6 = 1/2(4) + b

6 = 2 + b

6 - 2 = b

4 = b

The y-intercept is 4 or (0, 4).

The equation of the line is y = 1/2x + 4.

Malorie took out a loan to build a deck.The loan was for $15000 and had a 7.5% simple interest rate. If she paid a total of $1,6
attashe74 [19]

Answer:

  • The final value (FV)  that is paid in a loan (which is the sum of the capital and the interests) equals the present value (PV) of the loan  multiplied by (1+i\times{n}), in a simple interest context, where "n" equals the periods of time and "i" equals the interest rate valid for that periodicity.
  • Then FV=PV\times(1+i\times{n}). In this case, PV=$15,000; final value equals FV=$15,000+1,687.5= $16,687.5.
  • We should clear "n" from our equation, which means: 16,687.5=15,000\times(1+n\times0.075). Dividing both sides by 15,000, then subtracting 1 both sides, and finally dividing by 0.075 both sides, results in n=1.5.
  • Then, Malorie had the loan for one an a half periods.
