As long as the new rectangle is not moved, just dilated, line EF will be parallel.
F(x) = | 4x - 1 | .....when f(x) = 7
7 = | 4x - 1 |
4x - 1 = 7 -(4x - 1) = 7
4x = 7 + 1 -4x + 1 = 7
4x = 8 -4x = 7 - 1
x = 8/4 -4x = 6
x = 2 x = -6/4
x = - 3/2
solutions are x = -3/2, 2
the two coterminal angles to the given one are:
8.98 rad and -3.58 rad
<h3>How to find coterminal angles?</h3>
For a given angle A in radians, the family of coterminal angles is defined as:
B = A + n*(2*pi)
Where pi = 3.14 rad
Where n can be any integer number.
In this case, we have an angle of 2.7 radians, then the coterminal angles are:
B = 2.7 rad + n*(6.28 rad)
One positive is what we get if we select n = 1, then:
B = 2.7 rad + 1*(6.28 rad) = 8.98 rad.
And if we select n = -1, we get the negative coterminal angle:
B' = 2.7 rad - 1*(6.28 rad) = -3.58 rad
Then the two coterminal angles to the given one are:
8.98 rad and -3.58 rad
