Here we're dividing, but what actually happens is that we get the " i " out of the denominator:
104i 104i 3-i 312i + 104 312i + 104
------- = --------- * -------- = --------------- = ----------------
3+i 3+i 3-i 9+1 10
Note that 3-i is the "conjugate" of 3+i.
Answer:
Total cost = <em>$</em> 4.55
Step-by-step explanation:
2(8a + 5b) -(2a + 3b)
<em>Part A: Simplify the expression shown above</em>
Exapanding the brackets;
16a + 10b - 2a - 3b
Collecting like terms;
16a - 2a + 10b - 3b
14a + 7b
<em>Part B: If a represents apples that cost $0.25 each and b represents bananas that cost SO. 15 each, what is the total cost based on the expression above?</em>
a = 0.25
b = 0.15
14a + 7b
Inserting the values into the equation;
14 (0.25) + 7(0.15)
Total cost = <em>$</em> 4.55
For an equation with slope m and point (x1,y1)
the equation is
y-y1=m(x-x1)
slope=(y2-y1)/(x2-x1)
(x,y)
(7,5)
(-4,-1)
slope=(-1-5)/(-4-7)=(-6)/(-11)=6/11
point is (7,5) or (-4,-1)
equation is
y-5=(6/11)(x-7) and
y+1=(6/11)(x+4)
The answer to the question is d
R u stupid?
Two less than 10 7 duh!!!!
Prime nothing besides 1 and 97 can be multiplied to get 97
