Answer: i don’t know
Step-by-step explanation: my brain hurts from trying to figure this out sorry
-x^3 + x^2/3 + 5 - 13/x
I don't know if this is correct
Answer:
10\pi[/tex]
Step-by-step explanation:
Circunferencia de un círculo = Pi veces diámetro
como el diámetro es igual a la mitad del radio, sabemos que si multiplicamos el radio por dos obtendremos el diámetro del círculo. Por lo tanto, 5 veces 2 = 10. Ahora hacemos 10 veces pi. El cual es 10 pi o 31.4159
Circumference of a circle = Pi times diameter
since the diameter is equal to half the radius, we know that if we multiply the radius by two we will obtain the diameter of the circle. Therefore, 5 times 2 = 10. Now we do 10 times pi. Which is 10 pi or 31.4159
<span>Pick two pairs: 4x - 3y + z = - 10. 2x + y + 3z = 0. ... Eliminate the same variable from each system: 4x - 3y + z = - 10. 2x + y + 3z = 0. ... Solve the system of the two new equations: -5y - 5z = - 10. 5y - 7z = 34. ... Substitute into one of the original equations: - x + 2y - 5z = 17. ... <span>Check: Does 2(1) + 4 + 3(- 2) = 0 ? Yes.</span></span>
Answer: the answer is 2x-3=15
Step-by-step explanation: It’s simple so whenever you see x in the equation you just plug 9 in it’s place for example:
equation 1: 2x-3=15 —> 2(9)=18-3= 15 for this equation 9 is the solution
equation 2: 4+5(9)=18 —> 4+45=49 and 49 does NOT equal to 18 therefor 9 is not a solution
equation 3: 3(9)+2= 29 and 29 does NOT equal to 25 so 9 is not the solution
equation 4: 81(9)-3=6 —> 726 does NOT equal to 6 so not a solution
equation 5: 24-2(9)=13–> 6 does not equal to 13 so 9 is not a solution
equation 6: 3(9)+7=8 —> 34 does not equal to 8 so 9 is not a solution
(hope this helps)
