Julie's overtime pay is $7 an hour more than her regular pay. She worked 6 hours at her regular wage and 4 hours at her overtime
sattari [20]
--------------------------------------
Define x:
--------------------------------------
Let her regular hourly pay be x.
Overtime pay = x + 7

--------------------------------------
Construct equation:
--------------------------------------
6x + 4(x+ 7) = 148
6x + 4x + 28 = 148
10x = 148 - 28
10x = 120
x = 12

--------------------------------------
Find Regular Pay
--------------------------------------
Regular Pay = x = $12

----------------------------------------------------------------------------
Answer: Her regular pay is $12 an hour.

In the diagram, AB is divided into equal parts. The coordinates of point A are _____, and the coordinates of point I are______ .
tankabanditka [31]

Answer:

The coordinates of point A are (-10,-4). The coordinates of I are (-3.875,-10.125).

Step-by-step explanation:

It is given that the the line AB is divided into equal parts. Therefor distance between two consecutive points are equal.

The point D is mid point of A and F.

(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

(-8.25,-5.75)=(\frac{x+(-6.5)}{2},\frac{y+(-7.5)}{2})

-8.25=\frac{x-6.5}{2}

-16.50=x-6.5

-10=x

-5.75=\frac{y-7.5}{2}

-11.50=y-7.5

-4=y

Therefore the coordinates of A are (-10,-4).

Similarly the pint H is midpoint of F and B.

(-4.75,-9.25)=(\frac{x+(-6.5)}{2},\frac{y+(-7.5)}{2})

The values of x and y are,

x=-3

y=-11

Therefore the coordinates of B are (-3,-11).

The point I is mid point of HB. H(-4.75,-9.25) and B(-3,-11).

(x,y)=(\frac{-4.75-3}{2},\frac{-9.25-11}{2})

(x,y)=(-3.875,-10.125)

Therefore the coordinates of I are (-3.875,-10.125).
