Which ordered pair is the solution to this system of equations?

Mathematics

Answer:

(5, - 3 )

Step-by-step explanation:

Given the 2 equations

x + 2y = - 1 → (1)

x - 3y = 14 → (2)

Subtracting (2) from (1) term by term will eliminate the term in x, that is

(x - x) + (2y - (- 3y)) = (- 1 - 14)

5y = - 15 ( divide both sides by 5 )

y = - 3

Substitute y = - 3 into either of the 2 equations

Substituting into (1)

x + 2(- 3) = - 1

x - 6 = - 1 ( add 6 to both sides )

x = 5

Solution is (5, - 3 )

In a packet of mixed candies there are 2 fruit centers for every 3 caramel centers. There are 30 candies in the packet. How many
WARRIOR [948]

Answer:

18 Caramel Centers

Step-by-step explanation:

Solution

So first off, we can group 2 and 3 toghether to make one "packet" with 5 candies in it. Now, we can divide 5 by 30 and get 6. Now we know how many packets/candies there are. After that, we can multiply 6 with 3 to get 18 caramel centers.

Verification:

2 x 6 = 12

3 x 6 = 18

12 + 18 = 30 ✅

What is the answer to (4-i)(6-5i) ?
hammer [34]
For this we must use foil and multiply
4*6
4*-5i
-i*6
-i*-5i
to get (respectively to above)
24
-20i
-6i
5i^2
combine all of those to get:
24-26i+5i^2
now, i squared is equal to -1, so we can simplify the above even further:
24-26i+5(-1)
24-26i-5
19-26i
Now, that would be your final answer. But if you want it in radical form you would get this: (just so you know, i is the square root of -1, or an imaginary number)
19-26 \sqrt{-1}

If(x)= 2e^x-1 +3 , what is f^-1 (x)
Rainbow [258]

Answer:

f^-1 (x) =  1+ln( (x-3)/2)

Step-by-step explanation:

hello :

let f(x) = y  so : y = 2e^(x-1) +3

calculate x :  e^(x-1) = (y-3)/2

for : y-3 > 0 :  x-1 = ln( (y-3)/2)    so : x= 1+ln( (y-3)/2)

If(x)= 2e^(x-1) +3 , what is f^-1 (x) =  1+ln( (x-3)/2)
