Answer:

Slope-intercept Form: $y = -3x + 16$

Step-by-step explanation:

Point-slope: $y- y_1 = m (x - x_1)$

$y + 1 = -3(x - 8)\\y \frac{+8}{-8} = -3x + \frac{+24}{-8} \\y = -3x + 16$

Answer:

option D

Step-by-step explanation:

$x^{2} + y^{2} = 16\\\\x^{2} = 16- y^{2}$

equation 2:

$\frac{x^{2}}{4} - \frac{y^{2}}{25} = 1$

so we have:

$\frac{16- y^{2} }{4}-\frac{y^{2}}{25}= 1$

Suppose you deposit $1,200 into a bank account. The account earns yearly simple interest at a rate of 1 3/4%. How many years wil

igor_vitrenko [27]

Answer:

6 years

Step-by-step explanation:

1.75% of 1,200 = 21

so 1 year= 21

21+21= 42 2 years

42+21=63 3 years

63+21=84 4 years

81+21=105 5 years

105+21=126 6 years

Or you can do

21x6=126 so it has to equal 6 years
