Since we want to find the value of k where the limit exists, set both equations equal to each other. Then substitute x = -1 in for each equation to find k.
[tex]kx - 3 = {x}^{2} + k[/tex]
1. Set both equations equal.
[tex] - k - 3 = 1 + k[/tex]
2. Substitute x = -1.
[tex] - 3 = 1 + 2k[/tex]
3. Solve for k by adding k to both sides. Continue the process of solving the equation.
[tex] - 4 = 2k[/tex]
[tex]k = - 2[/tex]
Thus, k = -2. Check by graphing the function.

A principal of $2200 is invested at 6.25% interest, compounded annually. How much will the investment be worth after 13 years
Answers
Answer:
Let S = Sum after 13 years
So = amount invested
t = time in years
i = annual interest rate = .0325
The S = So(1+i)t = $2,200(1.0325)13 = $3,334.21
After 13 years, the investment will be worth approximately $4365.67. To calculate the future value of the investment after 13 years with annual compounding interest, we can use the formula for compound interest.
Future Value (FV) = Principal (P) * (1 + (Interest Rate (r) / 100))^Time (n)
Where:
P = Principal (initial investment)
r = Annual interest rate (as a decimal)
n = Number of years
Given:
Principal (P) = $2200
Annual interest rate (r) = 6.25% = 6.25/100 = 0.0625 (as a decimal)
Number of years (n) = 13
Now, let's calculate the future value:
FV = $2200 * (1 + 0.0625)^13
FV = $2200 * (1.0625)^13
FV ≈ $2200 * 1.984396861 (rounded to 9 decimal places)
FV ≈ $4365.672097 (rounded to 2 decimal places)
After 13 years, the investment will be worth approximately $4365.67.

Suppose you have a 100 AED of coupons at Dubai Expo 2020. You spend 30 AED per game. Write an equation that models the total amount of money y you spent if you play x games.
Answers
The total amount of money y you spent if you play x games is expressed as y = 1/30x
Given the following
Total amount of AED of coupons at Dubai Expo 2020 = 100 AED
If you spend 30 AED per game, this can be expressed as:
30 AED = 1 game
100 AED = x game
Cross multiply
30 x = 100 * 1
30x = 100
x = 100/30
x = 10/3 games
This shows that 100 AED of coupons is used for 10/3 games
100 AED = 10/3 games
y AED = x games
Cross multiply
100 x = 10/3 y
100xy = 10/3
10 xy = 1/3
30xy = 1
y = 1/30x
Hence the total amount of money y you spent if you play x games is expressed as y = 1/30x

What is the in minute taken to cover 8.1km at an average speed of 5m/s
Answers
9514 1404 393
Answer:
27 minutes
Step-by-step explanation:
The relevant relations are ...
1 min = 60 s
1 km = 1000 m
time = distance/speed
__
time = (8.1 km)×(1000 m)/(1 km)/(5 m/s)×(1 min/(60 s))
= (8.1×1000)/(5×60) min = 27 min
It takes 27 minutes to cover 8.1 km at a speed of 5 m/s.
State the radius of this circle:
X^2 +Y^2=121
Answers
Answer:
radius = 11
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
x² + y² = 121 ← is the equation of a circle centred at the origin
with r² = 121 , then
r = [tex]\sqrt{121}[/tex] = 11
Player I has two coins. One is fair (probability 1 2 of heads and 1 2 tails) and the other is biased with probability 1 3 heads and 2 3 tails. Both players know these probabilities. Player I knows which coin is fair and which is biased. He selects one of the coins and tosses it. The outcome of the toss is announced to II. Then II must guess whether I chose the fair or biased coin. If II is correct there is no payoff. If II is incorrect, she loses 1.

Answer:
the second, fourth
Step-by-step explanation:
Since they all have the same fraction, but different positive and negatives in each equation we can find out which ones are equal to the original equation by how many negatives each equation has.
The original equation has 2
first option only has 1, so we can eliminate that one
the second option has two, and they are the same equation as the original, only in reverse, so this one will be one of the answers.
the third only has one so we can get rid of that one.
the fourth has 2, even though it has a + it still makes 2/5 negative, so it is one of the answers as well.
and the fifth one is positive, and there are no negatives, so we can get rid of that one.
so the answers would be the second and fourth ones.

Answers
Answer:
x=-3,y =4 z=-1
Step-by-step explanation:
x+2y-5z=10
y+2z=2
z=-1
Since z = -1, substitute into the second equation
y + 2(-1)=2
y -2 =2
y = 2+2
y=4
We can substitute into the first equation
x+2(4) -5(-1) =10
x+8+5=10
x+13 = 10
x = 10-13
x=-3

Jayson started with 200 anger units. Each week he lost 7 anger units. Write an equation that models Jayson's anger after t weeks.
Answers
Answer:
200 - 7t
Step-by-step explanation:
In order to make an equation, you have to figure out what needs to be put into it. Because Jason starts off with 200 anger units, that number will be subtracted by whatever amount he loses or gains per week, which would be 7. Then, in order to model the number of weeks, you would multiply the variable t to 7, so that it represents how many weeks Jason is going to lose 7 anger units. Therefore, our final equation should be:
Anger units = 200 - 7t

Hope this will help you!! <3
Answer:
Step-by-step explanation:
1) -90 ≥ 18x
Divide both sides by 18
-90/18 ≥ 18x/18
-5 ≥ x
2)x/3 > -8
Multiply by 3,
3*(x/3) > -8*3
x> -24
3)x - 10 < -26
Add 10 to both sides
x < -26 +10
x < -16
4) 19 -x ≥ 21
Subtract 19 from both sides,
-x ≥ 21 - 19
-x ≥ 2
Divide both sides by (-1)
x < -2
