Answer:
$390
Step-by-step explanation:
so he has $500
he took $40,which is $460
then he put in $30,$490
then he took away $100,$390
hopefully you understand
Increasing, passing through the origin, slope of 1. So (1,1),(2,2) (-3,-3) etc.
Answer:
The answer is 95°!
Step-by-step explanation:
180°-60°-25°= 95°
Answer:
The coordinates of point C after dilation will be: (3,-1)
Step-by-step explanation:
Dilation in the coordinate plane can be defined as enlargement. There are different types of dilation. The most simple one is dilation from origin.
A factor is used to dilate a point from the origin. For example, if (x,y) is a point and a is the scale factor then the coordinates of points will be:
(x,y) => (ax,ay)
Given point is:
C(6,-2)
r = 1/2
The new coordinates of point C will be:
The coordinates of point C after dilation will be: (3,-1)
Distribute the terms:
14x-56=77x
Get the variable to one side (subtract 14x from each side):
-56=63x
Divide both sides by 63:
-8/9=x
x=-8/9
