wellllllllllll when you plug in (-3) for x and (6) for y

10(-3)-5(6)=16

-30-30=16

-60=16

as you can see -60 is not equal to 16 so that means (-3,6) is not a solution :)

there is not point in trying the second equation cause we already know it is false :))

Which of the following is a solution to the equation x - 5/7 = -3/7
podryga [215]

Solve the equation:

          5              3
x  –  ——  =  –  ——
          7              7


           5
Add  ——  to both sides, so you get  x  isolated at the left-hand side:
           7

          5          5               3          5
x  –  ——  +  ——  =  –  ——  +  ——
          7           7              7           7

              3          5
x  =  –  ——  +  ——
              7           7


Now, add those fractions at the right-hand side of the equation:

          – 3 + 5
x  =  —————
               7

          2
x  =  ——     <———    this is the answer (first option:  2/7).
          7


I hope this helps. =)

Which of the following represents the factored form of f(x) = x3 − 64x?
sp2606 [1]

Answer:

x(x + 8)(x - 8)

Step-by-step explanation:

Given

x³ - 64x ← factor out x from each term

= x(x² - 64) ← x² - 64 is a difference of squares

= x(x + 8)(x - 8) ← in factored form
