For a given x, the value on the blue line is about 1/2 the value on the black line. The appropriate choice is
y = (1/2)x
The function is invertible on either side of the vertex. There are many possible answers. Ones that include the vertex are ...
x ≥ 3
or
x ≤ 3
27,459 --- 7,000
40,735 --- 700
7,000÷700 =10 times greater
There are 1600 metres in 1 mile, so 10095÷1600= 6.3 miles/s
Answer:
Simplifying
(2j + 1) * 9 + -7j = 0
Reorder the terms:
(1 + 2j) * 9 + -7j = 0
Reorder the terms for easier multiplication:
9(1 + 2j) + -7j = 0
(1 * 9 + 2j * 9) + -7j = 0
(9 + 18j) + -7j = 0
Combine like terms: 18j + -7j = 11j
9 + 11j = 0
Solving
9 + 11j = 0
Solving for variable 'j'.
Move all terms containing j to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + 11j = 0 + -9
Combine like terms: 9 + -9 = 0
0 + 11j = 0 + -9
11j = 0 + -9
Combine like terms: 0 + -9 = -9
11j = -9
Divide each side by '11'.
j = -0.8181818182
Simplifying
j = -0.8181818182
