Multiply the numerator and denominator by 4+5i
=[(2+3i)(4+5i)]/[(4-5i)(4+5i)]
=[(8-15)+(12+10)i] / [16+25] <span>= [ -7 + 22i ] / [41]
= (-7/41) + (22/41)i </span>
Intersecting on the y axis means x=0.
Plug x=0 in the equation to find out the y value of the intercept> 0+4y-24=0, y=6
so the both line passes the point (0,6)
two perpendicular lines have slopes that are negative reciprocals of each other, that is, if one slope is a/b, the other is -b/a
In this case, the line x+4y-24=0, 4y=-x+24, y=-1/4 x + 6, the slope is -1/4, so the slope of the perpendicular line is 4/1.
the equation is y=4x+6
Answer:
2.25
Step-by-step explanation:
area= length*width
length= 1.5
width= 1.5
1.5*1.5= 2.25
So, the answer is 2.25
A because D is less than or equal to, C is saying that 9 is bigger than 12 and B is incorrect because the sign is going to point towards the bigger number
I am sorry but this is incomplete. If you would like to PM me the full question I would love to help?
