Answer:
good news, the second one is relatively easy because it can be factored to (2x+1)(2x-3) which means that number two has solutions of -1/2 and 3/2
but for number one you have to either use the quadratic equation cause I've tried using synthetic division or just use the second equation to derive the first solutions so I tried move the graph up by two units and found that the intercepts are approximately (1+-√2)/2 or 1/2+-1/√2 for 4x^2-4x-1
A
These are multiples of 3 so 3x where x is a natural number from 0 to 4. In set builder notation we get {3x | x c Z, 0<= x <= 4}
By c I mean the symbol for “is an element of” which looks like a drawn out rounded upper case E. By <= I mean less than or equal to
B
These are integers from -3 to 3. That is {x| x c Z, -4 < x < 4
C
Here we have letter from the English alphabet from m to p.
{x| x c letter of the English alphabet from m to p}
Answer:
F=122 g=58 h=122
Step-by-step explanation:
F and h have same angle
H is same angle as 58
Sin = opposite/hypotenuse
cos = adjacent/hypotenuse
They are the same when opposite equals adjecent.
This only occurs when the angles are equal.
Answer: 45°
move -7 to the right side of the equal sign which becomes +7
x=2+7
7 + 2 is 9
=9
