Answer:

0

Step-by-step explanation:

21 - 4x = 4x + 21

~Subtract 21 to both sides

-4x = 4x

~Divide -4 to both sides

x = -x

~Add 8 to both sides

2x = 0

~Divide 2 to both sides

x = 0

Best of Luck!

Someone please help me with problem #7 !!!
ser-zykov [4K]

Answer: b and d

Step-by-step explanation:

Since the roots are x=2 and x=6, we can write the equation as

f(x)=a(x-2)(x-6)

Substituting in the coordinates of the vertex,

-4=a(4-2)(4-6)\\\\-4=-4a\\\\a=1

So, the equation is f(x)=(x-2)(x-6)

On expanding, we get f(x)=x^2 - 8x+12

Can you turn this sentence into an equation please? Three times twenty one more than a number is twelve. What is that number?
Zanzabum
X + 3 * 21 = 12
x + 63 = 12
x = 12-63
x = -51
The wording was a little odd, but I hope this is what you’re looking for!
