Zanzabum

Answer:

<h2>x = -3 or x = 1</h2>

Step-by-step explanation:

x^2+5x-4=3x-1\qquad\text{subtract}\ 3x\ \text{from both sides}\\\\x^2+5x-3x-4=3x-3x-1\\\\x^2+2x-4=-1\qquad\text{add 1 to both sides}\\\\x^2+2x-4+1=-1+1\\\\x^2+2x-3=0\\\\x^2+3x-x-3=0\\\\x(x+3)-1(x+3)=0\\\\(x+3)(x-1)=0\iff x+3=0\ \vee\ x-1=0\\\\x+3=0\qquad\text{subtract 3 from both sides}\\x+3-3=0-3\\\boxed{x=-3}\\\\x-1=0\qquad\text{add 1 to both sides}\\x-1+1=0+1\\\boxed{x=1}

PLEASE HELP!!!!!!!!
Taya2010 [7]

Answer:

9

Step-by-step explanation:

A quadratic equation is

ax^{2} +b+c

The axis of symmetry is 1. This means that some value of

-b/2a =1.

f(0) represent one of the horinzontal roots. Since f(0) equal 0, the constant is 0.

Notice how x=1 is the line of symmetry. This means when x=4 and x=-2, the quadratic is equal. so consider this equation.

a(4)^{2} +b(4)= a(-2)^{2} +b(-2)=-24

16a+4b= -24

4a-2b=-24

Solve for a by elimination.

2(4a-2b=-24)= 8a-4b=-48

Add both equations.

(16a+4b=-24)+(8a-4b=-48)= 24a=-92

Solve for a.

24a=-92

a=-3

Subsitute to in for b.

16(-3)+4b=-24

-48+4b=-24

4b=24

b=6

This means a=-3

b=6

So b-a is

6+3=9

quester [9]

Answer:

- 5

Step-by-step explanation:

Given

3x = 21 ( divide both sides by 3 )

x = 7

Then

23 - 4x = 23 - 4(7) = 23 - 28 = - 5

Alex can cut a cord into 7 pieces in 36 seconds. How long will it take him to cut the cord into 12 pieces? (the answer is NOT 61
Anika [276]

Answer:

x=61.71428 or 61 5/7

Step-by-step explanation:

We can use a ratio to solve

7 pieces              12 pieces

-----------------   = ---------------

36 seconds          x seconds

Using cross products

7x = 36*12

7x = 432

Divide by 7

7x/7 = 432/7

61 5/7

x=61.71428
