Answer:
Step-by-step explanation:
In a dilatation for find the new coordinates we have to multiply the initial value for the the scale factor
A’(-3, 12)
B’(9,6)
C’(-9,-3)
so the general rule is:
(x,y) -> (3x, 3y)
Answer: 8/5
Step-by-step explanation:
2^3 = 2*2*2 = 8
Therefore, you are evaluating 32/(8+12)
= 32/20
= 8/5
Answer:
B
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 )
y = 3x - 1 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (2, 2) into the partial equation
2 = 6 + c ⇒ c = 2 - 6 = - 4
y = 3x - 4 → B

Answer:
26.4% decrease
Step-by-step explanation:
The amount of change is ...
2500 -1840 = -660
As a percentage of the original price, that is ...
-660/2500 × 100% = -26.4% . . . . . negative change = decrease
The decrease is 26.4%.
