Answer: (4,3)
Step-by-step explanation:
We can rearrange the first equation to get [tex]3x-9=y[/tex].
Thus, we can conclude that:
3x - 9 = -2x + 11 5x - 9 = 11 [add 2x to both sides]5x = 20 [add 9 to both sides]x = 4 [divide both sides by 5]Thus, if x = 4, y=3(4)-9=3.
So, they graphs intersect at (4,3).

You invested $23,000 in two accounts paying 6% and 7% annual interest, respectively. If the total interest earned for the year was $1560, how much was invested at each rate?
Answer:
$ 18,000 was invested at 7%, and $ 5,000 was invested at 6%.
Step-by-step explanation:
Given that I invested $ 23,000 in two accounts paying 6% and 7% annual interest, respectively, and the total interest earned for the year was $ 1,560, to determine how much was invested at each rate, the following calculation must be performed:
23,000 x 0.07 + 0 x 0.06 = 1,610
22,000 x 0.07 x 1,000 x 0.06 = 1,600
21,000 x 0.07 x 2,000 x 0.06 = 1,590
20,000 x 0.07 x 3,000 x 0.06 = 1,580
19,000 x 0.07 x 4,000 x 0.06 = 1,570
18,000 x 0.07 x 5,000 x 0.06 = 1,560
Thus, $ 18,000 was invested at 7%, and $ 5,000 was invested at 6%.
the farmer has a field of 300m.he want to fence it with 4 rounded barbed wire . what is the total length of wire he requires
Answer:
1,200 meters.
Step-by-step explanation:
Given that the farmer has a field of 300 meters and he wants to fence it with 4 rounded barbed wire, to determine what is the total length of wire he requires, the following calculation must be performed:
300 x 4 = X
1,200 = X
Thus, the farmer needs 1,200 meters of barbed wire to be able to fence his entire field.

Consider A is a set and B is another set, if Au B=A n B, then
Select one:
O A = B
O A = Null
O A = U
OB = Null
Answer:
A = B
Step-by-step explanation:
The correct option is;
A = B
Check:
A = {2,3,4}
B = {2,3,4}
Au B = A n B = {2,3,4}
A or B cannot be null.
check
A = {2,3,4}
B = {}
Au B = {2,3,4}
A n B = {}

a bag of potato chips states that it weight is 5 2/3 oz the maximum measurement error is -+2/5 oz . write an absolute value inequality that represents the range for the weight, x, of the bag of chips
Answer: I (5 + 2/3) oz - xI ≤ 2/5 oz.
Step-by-step explanation:
If we have a mean M, and a measurement error e, then the absolute value inequality that represents the possible values of x, the variable, is:
IM - xI ≤ e
This means that x can be, at maximum, at a "distance" e from M.
In this case, we know that the mean weight is (5 + 2/3) oz, and the error is +- 2/5 oz, then the absolute value inequality that represents this situation is:
I (5 + 2/3) oz - xI ≤ 2/5 oz.

The half life of a certain tranquilizer in the bloodstream is 36 hours. How long will it take for the drug to decay to 87% of the original dose? Use the exponential decay model to solve.
Finding the Decay constant(λ):
λ = 0.693 / (half-life)
we are given that the half-life is 36 hours
λ = 0.693 / (36)
λ = 0.01925 /hour
Time taken for 87% decay:
Since decay is first-order, we will use the formula:
[tex]t = \frac{2.303}{decay constant}log(\frac{A_0}{A} )[/tex]
Where A₀ is the initial amount and A is the final amount
Let the initial amount be 100 mg,
the final amount will be 87% of 100
Final amount = 100*87/100 = 87 mg
Replacing the values in the equation:
[tex]t = \frac{2.303}{0.01925}log(\frac{100}{87} )[/tex]
[tex]t = \frac{2.303}{0.01925}*0.06[/tex]
t = 7.18 hours
We used 'hours' as the unit because the unit of the decay constant is '/hour'
Therefore, the drug will decay to 87% of initial dosage after 7.18 hours

1. Addie, Namanda, and Taylor can paint a room together in 6 hours. If Addie and Namanda could do it in 10 hours, how long would it take Taylor by herself?
Answer:
15 hours
Step-by-step explanation:
A+N=10
(1/A+N)=1/10
(1/A+N) + (1/T)= 1/6
1/T= 1/6-1/10
1/T= (5-3)/30 = 2/30 = 15
It will take Taylor alone 15 hours to complete the work alone.
What is function?A function is a relation between a dependent and independent variable.
Mathematically, we can write → y = f(x) = ax + b.
Given is that Addie, Namanda, and Taylor can paint a room together in 6 hours. Addie and Namanda could do it in 10 hours.
We can write that Addie, Namanda, and Taylor's 1 hour work as (1/6).
Addie and Namanda's 1 hour work = 1/10
So -
1/A + 1/N + 1/T = 1/6
1/A + 1/N = 1/10
Now -
1/T = 1/6 - 1/10
1/T = 10/60 - 6/60
1/T = 4/60
T = 60/4
T = 15 hours
Therefore, it will take Taylor alone 15 hours to complete the work alone.

Write an equation for the quadratic graphed below
x-intercepts: (-1,0) and (2,0). y-intercept: (0,-3)
Answer:
Step-by-step explanation:
LOL The graph doesn’t match the y intercept :)
Anyway
If we have point (0,-3) we have a quadratic of
y=ax^2+bx-3 we are given points (-1,0) and (2,0) so
a-b-3=0 and 4a+2b-3=0
4a+2b-3+2(a-b-3)=0
4a+2b-3+2a-2b-6=0
6a-9=0
6a=9
a=1.5, since a-b=3
1.5-b=3
b=-1.5
y=1.5x^2-1.5x-3
Answer:
1/2(x + 1)(x - 2)
Step-by-step explanation:
The x intercepts are -1 and 2, so the intercept form for this is y = a(x+1)(x-2).
We then by plug in the y intercept (0,-3)
-3 = a(0+1)(0-2)
1 * -2 = -2
-3 = -2a
division
-3/-2 = 3/2 which is 1.5
a = 1.5
y = 1.5(x+1)(x-2)

What is the total amount of interest using simple interest given the following: Principal: $20,000 Interest rate: 12% Time: 10 Months
Answer:
Amount = $22000
Step-by-step explanation:
Amount = Principal + Interest
Get the interest
Interest = PRT/100
Interest = 20,000*12*10/12*100
Interest = 200 * 10
Interest = $2000
Amount = $20,000 + $2000
Amount = $22000

It might help you to think of an exponent as indicating repeated multiplication. It tells you how many times the factor is repeated. In this case, it means ...
[tex]z^5\cdot z^6=(z\cdot z\cdot z\cdot z\cdot z)\cdot(z\cdot z\cdot z\cdot z\cdot z\cdot z)\\=z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z = z^{11}[/tex]

What is the volume of a hemisphere shaped coffee if the width of the coffee cup is about 16.51 cm (use 3.14 for pie)
1177.58
2355.16
18,841.25
12,850.80
Answer:
A. 1,177.58 cm³
Step-by-step explanation:
Volume of hemisphere = ⅔πr³
Radius (r) = 16.51 ÷ 2 = 8.255
π = 3.14
Plug in the values
Volume of the hemisphere-shaped cup = ⅔ × 3.14 × 8.255³
= 1,177.57783 ≈ 1,177.58 cm³
