(Remember, PEMDAS)
First find what 5^2 equal to
5 • 5 = 25
Then add 25 to 3
25 + 3 = 28
So Oc. :)
The values are equal.
Root 5.76= 2.4
-2.4=-2.4
You are given two equations, solve for one variable in one of the equations. Say you solved for x in the second equation. Then, plug in that value of x in the x of the first equation. Solve this (first) equation for y (as it should become apparent) and you'll get a number value. Plug in this numerical value of y into the y of the second equation. Solve for x in the second equation. And there you have it: (x, y)
Answer: c. x=-1 and x=7
Step-by-step explanation:
All you need to do is plug in 3 wherever you see an x!
y = 3(3) - 2(3)^2 + 5(3)^3
y = 9 - 2(9) + 5(27)
y = 9 - 18 + 135
y = -9 + 135
y = 126
Hope this helps!
