Directions: Write each equation in slope intercept form (y = mx + b)

Gnesinka [82]

Answer:

Below.

I Hope it helps :)

Step-by-step explanation:

Slope intercept form :

y=mx+b

$2x + y = 1$

Slope intercept form :

$y = - 2x + 1$

Equation :

$x - 2y = 8$

Slope intercept form :

$- 2y = - x + 8$

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

$3x + 2y = 4$

Slope intercept form :

$2y = - 3x + 4 \\$

Divide through by 2

$y = - \frac{3}{2} x + 2$

Equation :

$x + 2y = - 4$

Slope intercept form :

$2y = - x - 4$

Divide through by 2

$y = - \frac{1}{2} x - 2$

$4x + y = 1$

Slope intercept form =

$y = - 4x + 1$

Equation :

$x + y = - 2$

Slope intercept form :

$y = - x - 2$

MAJORR HELP!!!

WINSTONCH [101]

Answer:

a)$1628.90

b)$1647.00

c)$1648.72

Step-by-step explanation:

The question is on compound interest.

The formula to apply here is;

$A=P(1+\frac{r}{n} )^{nt}$

where

P=principal /beginning amount
r=interest rate as a decimal
n=number of compoundings a year
t=total number of years

a) If compounded annually, n=1

p=$1000, r=5%=0.05 t=10

Amount will be;

$A=1000(1+\frac{0.05}{1} )^{10} \\\\\\A=1000(1.05)^{10} \\\\\\A=1000*1.6289=1628.90$

Amount=$1628.90

b) If compounded monthly, n=12

p=$1000, r=5%=0.05, t=10, n=12

$A=1000(1+\frac{0.05}{12} )^{12*10} \\\\\\A=1000(1.0042)^{120} \\\\\\A=1000*1.647=1647$

Amount=$1647.00

c)If interest compounded continuously, it means the principal is earning interest constantly and the interest keeps earning on the interest earned.Here the formula to apply is;

A=Pe^rt where e is the mathematical constant e=2.71828182846

Hence the amount will be;

$A=Pe^{rt} \\\\\\A=1000*e^{0.05*10} \\\\\\A=1000*2.71828182846^{0.5} \\\\\\A=1648.72$

Amount=$1648.72

Answer:

A, D, E . . . not a function

B, C . . . a function

Step-by-step explanation:

Look at the lists of first numbers:

{2, 3, 5, 2} . . . 2 is repeated, not a function

{3, -3, 0, 5} . . . no repeats, is a function

{1, 2, 3, 4} . . . no repeats, is a function

{4, 6, 8, 4} . . . 4 is repeated, not a function

{2, 2, 2, 2} . . . 2 is repeated, not a function
