a)
Image VMS is reduced to image M'V'S'.
b) the scale factor is 2/3
M(-3,3)
Multiply -3 and 3 with 2/3 your result = -2 and 2.
Scale factor for coordinate M = (-3,3) andN = (-2,2)
Since it is reduction, -2/-3 or 2/3
Therefore, scale factor = 2/3
Answer:
No because the 2 is outside of the parentheses meaning it should be 9^2
Step-by-step explanation:
Answer: No; this expression is NOT a prime trinomial. In fact, this expression is not a trinomial—but rather a binomial.

Answer:
21.9 m
Step-by-step explanation:
Take the amount for one dress and multiply by 6
3.65*6 =21.9 m
Y = x^2 +2x
y = 3x +20
so:
x^2 + 2x = 3x + 20
subtract 3x from both side:
x^2 +2x -3x = 20
combine like terms:
x^2 -x = 20
subtract 20 from each side:
x^2 -x -20 = 0
factor the polynomial:
(x-5) (x+4) = 0
solve for x
x = 5 and x = -4 ( 5-5 = 0 and -4 +4 = 0 )
replace x = 5 in 2nd equation: y = 3(5) +20
y = 15 +20
y = 35
replace x with -4 in same equation:
y = 3(-4) +20
y = -12 +20
y = 8
so solution is (5,35) and (-4,8)
