Ok, to show that she is incorrect we can use any other number in both equations and they will not be equal. the number she used does turn out equal but that does not mean the equations are equal.
for example
2 times 3=6
3 to the power of 2 is 9
that shows the expressions are not equal
For this case we represent in the complex plane numbers of the form:
a + bi
Where,
a: real part
bi: imaginary part
We represent the real part on the x axis.
We represent the imaginary part in the y axis.
Therefore, for the following numbers we have:
-3 + 8i: quadrant 2
4i: on the vertical axis
6: on the horizontal axis
5-2i: quadrant 4
Answer:
-60
Step-by-step explanation:
Answer:
(f+g)(x)=5x-4
(f*g)(x)=(4x^2-19x-5)
(f-g)(3)=(-15)
Step-by-step explanation:
(f+g)(x)=(x-5)+(4x+1)=(5x-4)
(f*g)(x)=(x-5)(4x-1)=(4x^2-19x-5)
(f-g)(3)=(x-5)-(4x-1)=(3-5)-(4(3)+1)=(-2)-(12+1)=(-2)-(13)=-15 substitute 3 for x
