Answer:

y = 2x - 5

Step-by-step explanation:

slope-intercept form is y = mx + b with m being the slope of the line and b being the y-intercept (where the line touches the y-axis)

First we can find m using the formula for slope, \frac{rise}{run} (or \frac{y_1 - y_2}{x_1 - x_2}), which is the change in y over the change in x.

We can use any points on the line, but I am going to use (4, 3) and (3, 1) for this example. We can now find the slope.

\frac{3-1}{4-3} = \frac{2}{1}

This means your slope is 2, which means m is 2.

Finding the y-intercept is easy. This line crosses the y-axis at -5, and so b is -5.

Now we can plug in the values into our original equation to get the equation of the line.

y = 2x - 5

That is the answer

Answer:

12

Step-by-step explanation:

(whole secant) x (external part) =    (whole secant) x (external part)

( 7+x+2) * 7 = ( 6+8) * 6

Combine like terms

(9+x) *7 = 14*6

Distribute

63 +7x = 84

Subtract 63

63 +7x -63 = 84-63

7x =21

Divide by 7

7x/7 = 21/7

x = 3

KM = x+2+7

      = 3+2+7

      =12

Michael invested 5,000 in an account that has a 5.5% annual interest rate. What equation best describes investment after T years
ivolga24 [154]

Answer:

V = 5000 +  275*T   for simple annual interest

or:   A = 5000 * (1.055)^T   for an annual compound interest

Step-by-step explanation:

I assume this is a simple interest rate.  If not I will give the one for compound interest.

V = 5000 + 5000* 0.055 * T      (Value of account after T years)

V = 5000 +  275*T   for simple annual interest

or:   A = 5000 * (1.055)^T   for an annual compound interest

Help me with this pls
Dvinal [7]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

6x + 10y = 8 ( subtract 6x from both sides )

10y = - 6x + 8 ( divide each term by 10 )

y = - \frac{6}{10} x + \frac{8}{10} = - \frac{3}{5} x 6 + \frac{4}{5} ← in slope- intercept form

with slope m = - \frac{3}{5} → C
