Answer: 3 + 10i
Step-by-step explanation:
Complex numbers follow the same rules that real numbers do when it comes to addition and subtraction. Removing the parenthesis we have:
[tex]5+6i-2+4i[/tex]
Combine the real parts, then combine the complex parts:
[tex]3+10i[/tex]

A grocery store bought yogurt for $2.20 per container and stored it in two refrigerators. During the night, one refrigerator malfunctioned and ruined 13 containers. If the remaining yogurt is sold for $3.94 per container, how many containers did the store buy if they made a profit of $105.38?
Answer:
96
Step-by-step explanation:
X be the total containers bought
Sales - cost = profit
4.08(X - 14) - 2.6X = 84.96
4.08X - 2.6X - 57.12 = 84.96
1.48X = 142.08
X = 96

Which graph represents the equation y = 1/3x +2
Answer:
No graph attached, but it would look like;
The y intercept (the line which meets the y axis) would be at positive 2,
it would then rise one and go over 3 to the right because they are both positive.
a man purchased a used car for $1000. He decided to sell the car for 20% above his purchase price. He could not sell the car so he reduced his asking price by 20%. If he sells the car at the reduced price, will he have a profit or a loss or will he break even?
Answer:
ok so they purchased price of the car is $1000 and the asking price will be 20% of $1000 so $1000 is a 100% so to get 20% of $1000 it will be 100% + 20% to get 120 percent so the asking price is 120 per cent of $1000 so 120 percent of $1000 is equals to 1200 dollars then you are told that he could not sell it by that price so he reduced it by 20% so this $1200 is 100% so he reduced it by 20% so it will be 100% - 20% to get 80% so this person sold his car at 80% so we will get 80% of $1200 and we will get $960 so he made a loss of $40

The graph of f ′ (x), the derivative of f(x), is continuous for all x and consists of five line segments as shown below. Given f (0) = 6, find the absolute maximum value of f (x) over the interval [0, 5].
graph of line segments increasing from x equals negative 4 to x equals negative 3, decreasing from x equals negative 3 to x equals 0, increasing from x equals 0 to x equals 3, constant from x equals 2 to x equals 4 and decreases from x equals 4 to x equals 5. x intercepts at x equals negative 4, x equals 0, x equals 5

Solve the following proportion for x
Answer:
x=500
Step-by-step explanation:
[tex] \frac{2}{3} = \frac{x}{750} \\ 3 \times x = 2 \times 750 \\ 3x = 1500\\ \frac{3x}{3} = \frac{1500}{3 } \\ x = 500 [/tex]
The attendance for a basketball team declined at a rate of 5% per game throughout a losing
season. 23,500 people attended the first game. How many people attended the 8th game?
Equation:
Answer:
Answer:
y=23,500
Step-by-step explanation:
General form for an exponential equation
y = ab^{x - h} + k y=ab
or
y = ab^x y=ab
Exponential growth and decay, when the quantity increases by a fixed percentage at regular intervals.
Exponential growth y = a(1 + r)^x y=a(1+r)
\because b = (1 + r) ∵b=(1+r)
Exponential decay y = a(1 - r)^x y=a(1−r)
x
\because b = (1 - r) ∵b=(1−r)
Where, a - initial value
r - decay or growth rate
x - Number of time intervals that have passed
Step 2: Set up an exponential equation from the given in formation
Given that:
Declined(Decay) rate r = 5% = 0.05
Players from the first game a = 23,500
Exponential decay y = a(1 - r)^x y=a(1−r)
x
y=23,500(1-0.05)^xy=23,500(1−0.05)
x
y=23,500(0.95)^xy=23,500(0.95)
x
Step 3: Build a table of values by evaluating the function at different x-values.
y=23,500(0.95)^xy=23,500(0.95)
If x = 0 then y = 23,500(0.95)^x y=23,500(0.95)
y = 23,500(0.95)^0 y=23,500(0.95)
y = 23,500 * 1 y=23,500∗1
y=23,500

If p and q vary inversely and p is 29 when q is 16, determine q when p is equal to 116.
Answer:
q = 4
Step-by-step explanation:
given p and q vary inversely then the equation relating them is
p = [tex]\frac{k}{q}[/tex] ← k is the constant of variation
to find k use the condition p = 29 when q = 16 , then
29 = [tex]\frac{k}{16}[/tex] ( multiply both sides by 16 )
464 = k
p = [tex]\frac{464}{q}[/tex] ← equation of variation
when p = 116 , then
116 = [tex]\frac{464}{q}[/tex] ( multiply both sides by q )
116q = 464 ( divide both sides by 116 )
q = 4
What are 2 equivalent ratios for 7:4
Answer:
14:8 and 21:12
Step-by-step explanation:
Equivalent fractions are fractions that look different but hold the same value. In this case, 7:4 = 14:8 = 21:12
Answer:
14:8, 28:16
Step-by-step explanation:
This could be anything. Ratios are like fractions; as long as you make changes to both sides, it will equal the same thing. So for the two examples I put, I simply multiplied both sides by 2 for the first one, and 4 for the second one.
But, you could multiply it by whatever you want, even negative numbers and fractions. However, I wouldn't try to complicate it, if the question didn't ask me to. Just keep to the easiest equivalents to make your life easier.
Hope this helps :))

Answer:
26 green marbles
Step-by-step explanation:
There are 100 marbles in the jar.
100 marbles are 100%
26% of these marbles are green.
Just as there are 100 marbles, we need to find how many marbles are green.
Let us do it like that: let a be the actual number of green marbles.
Marbles Percent
100 100%
a 26%
Let's find the ratio between 100% and 26% by doing 100/26 = 3.846153
We need to multiply 26 by 3.846153 in order to get to 100, right?
So same, I'll need to multiply a times 3.846153 in order to get 100.
3.846153 a = 100
divide both sides by 3.846153
a = 26 marbles
Therefore there are 26 green marbles.

Jodha wants to tip the pizza delivery person 20%. If the cost of the pizzas is $15.99, what would be a reasonable amount to tip?
Answer:
$3.20
Step-by-step explanation:
20%-> .20
15.99*.20
Answer:
$3.20
Step-by-step explanation:
divide 15.99 by 100
[tex]\frac{15.99}{100}[/tex]=0.1599
you now have 1%of the cost
multiply by 20 to get 20%
0.1599*20=3.198
round to 2 decimal places to get the amount he will tip
3.20
