How many times does the graph of 4x = 32 - x2 cross the x-axis?<br><br> 0<br><br> 1<br><br> 2
Yakvenalex [24]

Answer:

2

Step-by-step explanation:

4x = 32 - x2 would be much clearer if written as 4x = 32 - x^2.  Please use

" ^ " to indicate exponentiation.

Rewrite 4x = 32 - x^2 in the standard form of a quadratic:  x^2 + 4x - 32

Then the coefficients are a = 1, b = 4 and c = -32.

Find the discriminant.  It is b^2-4ac.  

Here, b^2-4ac = 4^2 - 4(1)(-32), or 16 + 128, or 144.

Because the discriminant is positive, we know immediately that this quadratic has two real, unequal roots.

So, the answer to this question is "the graph of 4x = 32 - x^2 cross the x-axis in two places."

Solve these equation<br><br>4(3-x)=(1-2x)​
serg [7]

To attempt this algebraic equation we will be multiplying 4 to (3 - x) bracket so as to form the term on L.H.S.

:\implies\tt{4(3 - x) = (1 - 2x)}

:\implies\tt{(12 - 4x) = (1 - 2x)}

:\implies\tt{12 - 4x = 1 - 2x}

Combining like terms, we get,

:\implies\tt{12 - 1 =  - 2x + 4x}

:\implies\tt{11 = 2x}

:\implies\tt{2x = 11}

:\implies\tt{x =  \frac{11}{2} }

:\implies\tt{x = 5.5}

  • The value of x is 5.5
