WEDNESDAY: Use the quadratic formula to solve the following: 3x^2 - 6x-12 = 0*a. 3.236 or -1.236
b. -3.236 or 1.236
c. 04 or 9
d. 2.487 or -5.859
e. None of these​

Answers

Answer:

a.) 3.236 or -1.236

Step-by-step explanation:

Used an online calculator for this answer...

Using the Quadratic Formula where

x = ( -b \pm √(b^2 - 4ac))/( 2a )\nx = ( -(-6) \pm √((-6)^2 - 4(3)(-12)))/( 2(3) )\nx = ( 6 \pm √(36 - -144))/( 6 )\nx = ( 6 \pm √(180))/( 6 )

The discriminant b^2−4ac > 0

so, there are two real roots.

Simplify the radical...

x = ( 6 \pm 6√(5)\, )/( 6 )\nx = ( 6 )/( 6 ) \pm (6√(5)\, )/( 6 )\nx = 1 \pm √(5)\,

This simplifies to...

x = 3.23607\nx = -1.23607

Answer:

#2 is not a function

Step-by-step explanation:

Although there can be multiple y-values attributed to a single x-value, there can only be ONE x-value(of a number) in a function, so #2 would be incorrect seeing as it uses the x-value, 2, two times.

-15m = -4m
-7m - 8 = m - 4
-3m - 8 = 4 - m
m - 4 = -7m - 8
-8 - 7m = -4 + m
-8 - 3m = 4 - m

Answers

first  you need to solve the equation
-2m-5m-8=3+(-7)+m
-7m-8=-4+m   or -7m-8=m-4
the second choice

also this choice
8 - 7m = -4 + m  the fifth one

To solve this problem, we must simplify the the equation:

Here is the base equation -2m - 5m - 8 = 3 + (-7) + m (Add all like terms):


#1 -2m - 5m - 8 = 3 + (-7) + m (Property of Addition)

#2 -7m - 8 = -4 + m (Most Simplified Equation)


The answer your would be the 2nd one. -7m - 8 = m - 4
