Answer:
the solution is (-4, -3)
Step-by-step explanation:
Multiply the first equation by 2. This produces 4x + 2y = -14.
Now combine this result with the second equation:
4x + 2y = -14
-3x - 2y = 10
------------------
x = -4
Subbing -4 for x in the first equation yields 2x - 4 = -7, or 2x = -3.
Then x = -3/2, and the solution is (-4, -3)
Answer:
4568
Step-by-step explanation:
F(x) = ㏑(x² - 4)
Domain: {-2 ≤ x ≤ 2}, or [-2, 2]
Answer:
first we should add both purchase price
$4.45 + $9.55 = $14
so that
$20 - $14
=$6
angle EPF = angle DPG
=> 4x + 48deg = 7x
=> 3x = 48 deg
=> x = 16
=> angle EPF = 4(16) +48 = 112deg
