x - 6y -- 2: = -8
--x + 5y + 3 = 2
3x - 2y - 42 = 18

Answers

Answer 1
1. Subtract first equation from second equation:

y = 7, if that first step is simplified.


2. Substitute y = 7 in any of the equations. (I am substituting in the first equation) :

You will get your x, which is x = 36


So now that you have your x and your y, you have finished solving the equation.

The answer is:
(x,y) = (36, 7)


Hope this helped! Have an awesome day!!

Answer:

1) x=8, y=138

2) x=110

Step-by-step explanation:

Answer:

1. x = 8, y =138

2. x = 110

Step-by-step explanation:

First we will need to find the value of x.

Since, I feel like being a kindergartener I'll do it the long way.

(5*2+2)+(6*2)

12+12

24

That wouldn't work

(5*8+2)=(6*8)

42+48=90

Therefore x = 8

Since we know 42 would be 42 degrees and it is a straight angle for both 5x+2 and y.

We would subtract 180-42=138.

Therefore, y = 138

2 would be simple. All we need to do is add 80+30=110 then subtract it by 180

180-110=70. Since x and the 70 degrees equal 180 degrees.

180-70=110

Therefore, your answer would be x= 110

if f(x-3)=7x+4 for all values of X what is the value of f(-7)

Answers

Answer:

-66

Step-by-step explanation:

We have the expression f(x-3) = 7x + 4, in which for x the value is -7.

To solve first substitute x next to f(x).

f((-7) - 3) = 7x + 4

(-7) - 3

f(-10) = 7x + 4

Now that we know x is equal to -10, you may substitute to the actual equation.

f(-10) = 7(-10) + 4

f(-10) = -70 + 4

f(-10) = -66

9514 1404 393

Answer:

  -24

Step-by-step explanation:

We want to evaluate the function when ...

  x -3 = -7

  x = -4 . . . . . add 3

Then, ...

  f(-7) = f(-4-3) = 7(-4) +4

  f(-7) = -24

__

Alternatively, we can rewrite the function to be f(x).

  f(x) = f((x+3) -3) = 7(x +3) +4

  f(x) = 7x +25

Now, f(-7) is ...

  f(-7) = 7(-7) +25 = -49 +25

  f(-7) = -24

f(x) = x^2. What is g(x)?

Answers

Answer:

D. g(x) = (1/4 x)^2

Step-by-step explanation:

We have to choose a solution in which the point (4, 1) works.

A) g(x) = 1/4(x^2) = 1/4(4^2) = 1/4(16) = 4 ≠ 1

B) g(x) = (1/2 x)^2 = (1/2 * 4)^2 = 2^2 = 4 ≠ 1

C) g(x) = 4(x^2) = 4(4^2) = 4(16) = 64 ≠ 1

D) g(x) = (1/4 x)^2 = (1/4 * 4)^2 = 1^2 = 1

- There are 130 people in a sport centre,
76 people use the gym,
60 people use the swimming pool,
32 people use the track,
23 people use the gym and the pool.
8 people use the pool and the track
20 people use the gym and the track,
6 people use all three facilities,
A person is selected at random
What is the probability that the person uses exactly one of the facilities?

Answers

Answer:

0.6462 = 64.62% probability that the person uses exactly one of the facilities

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

20 people use the gym and the track and 6 people use all three facilities

So 20-6 = 14 use exactly the gym and the track and 6 use all three.

8 people use the pool and the track

So 8 - 6 = 2 use exactly the pool and the track.

23 people use the gym and the pool.

So 23 - 6 = 17 use exactly the gym and the pool.

32 people use the track

So 32 - (6 + 14 + 2) = 10 use only the track.

60 people use the swimming pool

So 60 - (6 + 2 + 17) = 35 use only the pool.

76 people use the gym

So 76 - (6 + 14 + 17) = 39 use only the gym

What is the probability that the person uses exactly one of the facilities?

Out of 130, 39 + 35 + 10 = 84 use exactly one of the facilities.

84/130 = 0.6462

0.6462 = 64.62% probability that the person uses exactly one of the facilities

P = 18000 deposit

T = ?

Putting into the formula we have

1300 = 18000x1.19/100xT

1300 = 18000x0.0119xT

1300 = 214.2T

Divide through to get T

T = 1300/214.2
