Step-by-step explanation:
y = 2kx², where k is a real constant.
We have:
2k(1)² - 2k(3)² = 32 or 2k(3)² - 2k(1)² = 32.
=> 2k - 18k = 32 or 18k - 2k = 32
=> -16k = 32 or 16k = 32
=> k = -2 or k = 2.
When x = -2,
y = 2(-2)(-2)² or y = 2(2)(-2)².
=> y = -16 or y = 16.
Answer:
2x + x + 63 = 180 to find x.
m<1 = 78 degrees
m<2 = 102 degrees
Step-by-step explanation:
Combine like terms: 3x + 63 = 180
Subtraction: 3x = 117
Division: 3x/3 = 117/3
Final Answer: x = 39
m<1 = 2(39) = 78 degrees
m<2 = (39 + 63) = 102 degrees
Check work: 102 + 78 = 180
(180 is the measure of a straight line such as the one represented here)
Answer:
there is hint for u in the book darling
you can refer example 4 in the same book
Answer:
Its A
Step-by-step explanation:
Answer: C
Working out: (55,000 x 20) - (30,000 x 20) = $500,000
$1,100,000 - $600,000 =$500,000
