Answer:
(a) A'(-2, 1), B'(-4, -3), C'(-7, 0)
Step-by-step explanation:
If X is the center of rotation, the coordinates of point P are transformed like this:
P' = -(P -X) +X
P' = 2X -P
(x, y) ⇒ (2(-5) -x, 2(3) -y)
(x, y) ⇒ (-10-x, 6-y)
__
Your points are transformed to ...
A(-8, 5) ⇒ (-10-(-8), 6-5) = A'(-2, 1)
B(-6, 9) ⇒ (-10-(-6), 6-9) = B'(-4, -3)
C(-3, 6) ⇒ (-10-(-3), 6-6) = C'(-7, 0)
These coordinates match the first choice.
Answer:
16 1/3 lbs
Step-by-step explanation:
We can write a ratio to solve
7 lbs x lbs
-------------- = -------------
3 loaves 7 loaves
Using cross products
7 * 7 = 3x
49 = 3x
Divide each side by 3
49/3 = 3x/3
16 1/3 lbs

6. co-interior angles
They are related because they have a relationship with thedecimal
Answer:
Step-by-step explanation:
Let the equation of the line 'a' is,
y = mx + c
Here, m = slope of the line
c = y-intercept
For line 'a',
Slope of the line =
m =
m =
y-intercept = 20
Therefore, equation of the line 'a' is,
y =
Similarly, equation of the line 'b' is,
y = m'x + c'
Slope of the line =
m' =
m' =
y-intercept = 0
Therefore, equation of the line is 'b' is,
y =
1). Line 'b' represents a proportional relationship → FALSE
2). The constant of proportionality of y to x for line 'a' is → FALSE
3). The ratio of y-coordinate to x-coordinate of one of the points on line b is 25 : 8 → FALSE
4). let a passes through the point so the constant of proportionality is → TRUE
