How do you solve this systems of equations problem 2r +3s=-5 6s=2r

Mathematics

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

2r + 3s = - 5 → (1)

6s = 2r → (2) ( divide both sides by 2 ), then

r = 3s

Substitute r = 3s into (1)

2(3s) + 3s = - 5

6s + 3s = - 5

9s = - 5 ( divide both sides by 9 )

s = - \frac{5}{9}

Substitute this value into either of the 2 equations and evaluate for r

Substituting into r = 3s, then

r = 3 × - \frac{5}{9} = - \frac{5}{3}

Solution is r = - \frac{5}{3} and s = - \frac{5}{9}

(6(1) = -5<br> 1) Find (4) in the sequence given by<br> (6(n) = b(n − 1) +9
Sloan [31]

Answer:

f(4) = 22

Step-by-step explanation:

I think that you type wrongly.

we have f(1) = -5

and f(n) = f(n-1) + 9

Find f(4)

Then

with n= 2 we have f(2) = f(1) + 9 = - 5+ 9= 4

with n= 3 we have f(3) = f(2) + 9 = 4 + 9= 13

and finally with n= 4 we find f(4) = f(3) + 9 = 13+ 9= 22

So f(4) = 22

Hope you understand.

* ANSWER PLS * What is the value of x?
uysha [10]

Answer: 21°

Since angles DAE and CBE are inscribed on arc AC, they r equal

Hence angle CBE = 42°

So angle DAE = 42/2 = 21°

The manager of a video game store found that 35 of the 140 people who preordered the latest baseball game canceled their orders
irina1246 [14]

Using the data presented in the problem, you are asked to predict the probability that future customers will cancel their preorders. To find the probability, you have to divide the number of people who cancelled their preorders by the total number of people who preordered.

35 people / 140 people = .25 or 25% probability that the future customers will cancel their preorders.
