Find the solution to the system of equations given below: x=-4 -5x-4y=16 PLS HELP

Mathematics

poizon [28]3 years ago

Answer:

Step-by-step explanation:

Since x=-4 plug in the -4 into the equation to find y,

-5(-4)-4y=16

20-4y=16                                                                                                                             -20       -20                                                                                                                   __________

-4y=-4

-4y/-4=-4/-4

___________

y=1

So now you found both x and y so plug in both now to check if both are correct.

-5(-4)-4(1)=16

20-4=16

16=16

So both y and x are correct.

Hope this helps!:)

VashaNatasha [74]

Answer:

3/5 of students who take the first path and pass

Step-by-step explanation:

* Lets explain how to solve the problem

- There are two pathways through the math program

- At this school 3/4 of students follow the first​ path

- The rest take the second path

- During one​ semester, 80% of the students who follow the first path

 pass the​ program

- 20​% of the students who follow the second path pass it

- We want to know the fraction of students who take the first path

 and pass

* Lets solve the problem

∵ 3/4 of students follow the first​ path

∵ The rest take the second path

∴ The fraction of the rest = 1 - 3/4 = 1/4

∴ 1/4 of the students follow the second path

∵ 80% of the students who follow the first path pass the​ program

∵ 80% = 80/100 = 8/10 = 4/5

∵ 4/5 of the students who follow the first path pass the​ program

∵ 3/4 of students follow the first​ path

∴ 4/5 of 3/4 of the students of the first path pass

∵ 4/5 of 3/4 = 3/5

∴ 3/5 of students who take the first path and pass

What is the factored form of x^3 - 729
tensa zangetsu [6.8K]

Answer:

(x - 9)(x^2 + 18x + 81).

Step-by-step explanation:

Use the difference of cubes factorization, which claims that a^3 - b^3 = (a - b)(a^2 + ab + b^2)

x^3 - 729 = (x - 9)(x^2 + 18x + 81)
