Solve the system of equations: x+y=6 3x−5y=2

Mathematics
1 answer:
Crank2 years ago
7 0

Answer:

x=4, y=2

Step-by-step explanation:

x+y=6

3x−5y=2

Multiply the first equation by 5

5(x+y)=6*5

5x+5y = 30

Add this to the second equation

5x+5y = 30

3x -5y = 2

---------------------

8x    = 32

Divide each side by 8

8x/8 = 32/8

x = 4

Now we need to find y

x+y =6

4+y =6

Subtract 4 from each side

4+y-4 =6-4

y = 2

Find the 58"" term of the following arithmetic sequence,<br> 18, 23, 28, 33,
Anna11 [10]

Answer:

303

Step-by-step explanation:

So the equation to find a term is An=a1+(n-1)d

An represents the value of the number (n)

and n is the selective that you want

d is the difference between the first and second term which is 23-18=5, and you can see that adding 5 to the previous term gives the following term.

a1 is the first term in the sequence

so knowing all that now you can go back and inset all variables into the equation

An=18+(58-1)5

An=303

Hope that helps :)

98 POINTS AND BRAINLIEST TO BEST ANSWER!!!!!!!!!!!
lidiya [134]

Part A: the x-cordinates of where the graphs of the equations intercept are solutions because they make each side of the equation equal to the same value, making them equal. Basically, both functions put out the same value at that point x, making them equal.

Part B: See the attached image. From the tables we can see that both equations have the same output at x=-2, so that is where the graphs would intersect and that would be the solution. They both put out .0625 at x=-2

Part C: You can solve the equation 4^x=2^(x-2) graphically by plotting both sides of the equation as separate functions. In your graphing calculator, you would plot y=4^x and y=2^(x-2), and see at what x-value they intersect to find the solution

What is a factor pair of 72
zubka84 [21]

Hey there!

- Factor pair basically 2 factors that you multiply the given numbers to each other to get a given product (answer)

“Factors of 72”

- So we have to find MULTIPLES that gives you 72

Answers ⬇️

▸ 1 • 72 = 72

(SAME thing with 72 • 1 = 72)

▸ 2 • 36 = 72

(SAME with 36 • 2 = 72)

▸ 3 • 24 = 72

(SAME with 24 • 3 = 72)

▸ 4 • 18 = 72

(SAME with 18 • 4 = 72

▸ 6 • 12 = 72

(SAME with 12 • 6 = 72)

▸ 8 • 9 = 72

(SAME with 9 • 8 = 72)

Good luck on your assignment and enjoy your day!
