Write a system of equations with the solution (5, 2).

Answers

Answer 1
This is one of those questions where they are just trying to confuse you by giving so many possibilities.

(-5, 2) Since (x, y)
x = -5
y = 2

a(x) + b(y) = s a(-5) + b(2) = s
c(x) + d(y) = t c(-5) + d(2) = t

Let's say a = 1, b = -2, c = 4, d = 5. These choices are random since it will work for any numbers.
You just need to solve the totals s and t
x - 2y = s -5 - 2(2) = -9 -5 - 4 = -9 s = -9
4x + 5y = t 4(-5) + 5(2) = -10 -20 + 10 = -10 t = -10

One of any number of solutions
x - 2y = -9
4x + 5y = -10

Solving the system we can show we will end up with our original solution
13y = 26 y = 2 x - 4 = -9 x = -5
(-5, 2)

weeks??

Answers

Answer:

maybe 0 cause I waste my money in videogames

Okay. Since he already has $270 and he gets $80 from his paycheck each week, you will divide $80 dollars a week x 3 weeks = $240
So you add what he already has to the one he gets in 3 weeks, $270 + $240 = $510
He will get $510 dollars after 3 weeks.

If person a and person b go fishing and both catch fish. If person a gives half their fish to person b and then they have equal amounts. How many fish does each have

Answers

Answer:

The number of fishes person b initially has is 0

The number of fishes person a initially has is x, where x is any natural number

Step-by-step explanation:

The given parameters are;

let x represent the number of fish person a catches and let y represent the number of fishes that person b catches, we have;

x - x/2 = y + x/2

2·x - x = 2·y + x

2·x = 2·y + 2·x

∴ y = 0

Therefore;

The number of fishes person b initially has = 0

The number of fishes person a initially has = x, where x is any natural number.

The Positions of Abuja (Nigeria) and Bonn (Germany) to the Nearest degree are (9°N,7°E)and (51°N,7°E) respectively.(use R=6400km to calculate their distance apart to 2s.f)​

Answers

Answer:

4656.46km

Step-by-step explanation:

Given that:

Abuja (Nigeria) = (9°N,7°E)

Bonn (Germany) = (51°N,7°E)

Longitudinal difference = 51 - 9 = 42°

Radius of the earth (R) = 6400

Distance = θ/360 * 2πr

r = Rcos7° = 6400 * cos7 = 6352.2953

Hence,

Distance = (42/360) * 2 * 3.142 * 6352.2953

Distance = 0.1166666 * 2 * 3.142 * 6352.2953

Distance = 4656.4757 km

There are 14 teams in a basketball league.
Each team plays every other team twice
during the season.
a) Suppose that you want to determine
how many games, in total, are played.
Suggest a simpler problem that you
could solve first.
b) How many games, in total, are played
during the season?​

Answers

Answer:

Step-by-step explanation:

Given that :

Number of teams = 14

Each team plays every other team twice ;

Using the combination formula :

nCr = n! ÷ (n-r)! r!

14C2 = 14! ÷ (14 - 2)! 2!

14C2 = 14! ÷ (12)! 2!

14C2 = (14 * 13) ÷ 2 * 1

14C2 = 182 / 2

14C2 = 91

Hence, since they are going to be playing each other twice :

2(14C2)

2 * 91 = 182games

x=2y-4
7x+5y=-66
what is the x- value​

Answers

Answer:

x = -8

Step-by-step explanation:

x = 2y - 4 --- Equation 1

7x + 5y = -66 --- Equation 2

I will be using the substitution method to solve this.

Substitute x = 2y - 4 into Equation 2:

7x + 5y = -66

7(2y - 4) + 5y = -66

Evaluate.

14y - 28 + 5y = -66

Evaluate like terms.

19y - 28 = -66

Isolate 19y.

19y = -66 + 28

     = -38

Find y.

y = -38 ÷ 19

y = -2 --- Equation 3

Substitute y = -2 into Equation 1:

x = 2y - 4

x = 2(-2) - 4

Evaluate.

x = -4 - 4

x = -8

Jill is filling a water trough for her horse. Using pump A, the trough is filled up in half an
hour. Using pump B, the trough is filled up in three quarters of an hour. How long does it
take to fill the trough using both pumps?

Answers

Answer:

It will take 18 minutes to fill the trough using both pumps.

Step-by-step explanation:

Given that:

Time taken by pump A = half hour = 30 minutes

Time taken by pump B = three quarters of an hour

One quarter = [tex]\frac{1}{4}[/tex]

One hour = 60 minutes

Three quarters of an hour = [tex]\frac{3}{4}*60[/tex] = 45 minutes

Let,

x be the time taken by both pumps to fill the trough.

[tex]\frac{1}{time\ taken\ by\ pump\ A}+\frac{1}{time\ taken\ by\ pump\ B}=\frac{1}{Time\ taken\ by\ both\ pumps}[/tex]

[tex]\frac{1}{30}+\frac{1}{45}=\frac{1}{x}\\\\\frac{3+2}{90}=\frac{1}{x}\\\\\frac{5}{90}=\frac{1}{x}\\\\\frac{1}{18}=\frac{1}{x}\\x=18[/tex]

Hence,

It will take 18 minutes to fill the trough using both pumps.

the cable company charges a monthly fee of $45. Each movie rental is $1.99. you owe $68.88. How many movies did you rents?

Answers

Answer:

12 movies

Step-by-step explanation:

If you do not rent any vidoes you will be charged $45 no matter what, so...

Movies + 45 = total charge

each movie is 1.99 and you owe (total charge) $68.88

equation:

1.99x + 45 = 68.88

          -45       -45    (subtract 45 from each side to keep equation balanced)

1.99x = 23.88  (now divide both sides by 1.99 to get x alone)

     x = 12

you rented 12 movies
