Answer:
-8/81
Step-by-step explanation:
4+1/2=8/9k, 4+1/2 also equals 8/2+1/2 which is 9/2
(9k)9/2=-8/9k(9k), multiply each side by 9k
81k/2=-8
(2)81k/2=-8(2), multiply each side by two
81k=-8
81k/81=-8/81, divide each side by 81
k=-8/81
6^5 = 6 x 6 x 6 x 6 x 6 = 7776
Answer: D) 48 inches by 64 inches
=============================================
Explanation:
The scale factor is 1/4 = 0.25, meaning that the original preimage is larger and it is reduced to get the image. The reduced width is 12, so the original width is 12/0.25 = 48 inches. The reduced length is 16 making the original to be 16/0.25 = 64.
--------
note that
48*0.25 = 12
64*0.25 = 16
showing how a 48 by 64 rectangle is reduced to a 12 by 16 rectangle after applying the scale factor to each dimension
Answer:
g(x) - f(x) = x² - 4x - 2
The domain would be all real numbers for x. Or (-∞, ∞). Because there are no values that you could plug in for x that would make the function undefined.
Step-by-step explanation:
g(x) - f(x) = (x² - x + 2) - (3x + 4)
= x² - x + 2 - 3x - 4
= x² - 4x - 2
ANSWER
The graph of f(x) is horizontally stretched.
EXPLANATION
The given function is
The vertex of this function is (-4,-6)
The factor ⅔ strectches the graph horizontally in the graph of f(x) opens wider than the parent function
y=|x|
The negative factor will make the graph open downwards. It is a reflection in the x-axis.
The domain of the graph is all real numbers.
