Please can someone just answer question 7C

y = -2/3x - 1

Step-by-step explanation:

Step 1: The first thing that we need to do is to find the slope of a given line

The explicit equation of a given line is: y = 3/2x + 5/2

So the slope is m = 3/2:

Step 2: The perpendicular slope (m1) is negative reciprocal of the slope m.

m1 = -2/3

So the perpendicular line will have a slope of m1 = -2/3

Step 3: Now we have a point and the slope so we can use point-slope form, which is: y - y0 = m1(x - x0)

In this example we have: m1 = -2/3, x0 = 0 and y0 = -1. After substitution we have:

y - y0 = m1(x - x0)

y - (-1) = -2/3(x - 0)

y + 1 = -2/3x + 0

y = -2/3x + 0 - 1

y = -2/3x - 1

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
