Identify the vertex for the graph of y = −3x^2 + 6x − 4
algol [13]

Answer:

the vertex is (1,-1)

Step-by-step explanation:

y = −3x^2 + 6x − 4


the vertex is at

h= -b/2a  where ax^2 +bx+c

h= -6/2(-3)

h= -6/-6

h=1

substitute this in to find the y value

y = -3(1)^2 +6(1)-4

y = -3+6-4

y = -1

the vertex is (1,-1)

What is the value of x?<br> 6.75+ x = 131
yanalaym [24]

Answer:

x = 497/4 = 124.250

Step-by-step explanation:

Step  1  :

           27

Simplify   ——

           4

Equation at the end of step  1  :

  27          

 (—— +  x) -  131  = 0

  4          

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  4  as the denominator :

        x     x • 4

   x =  —  =  —————

        1       4  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

27 + x • 4     4x + 27

——————————  =  ———————

    4             4  

Equation at the end of step  2  :

 (4x + 27)    

 ————————— -  131  = 0

     4        

Step  3  :

Rewriting the whole as an Equivalent Fraction :

3.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  4  as the denominator :

          131     131 • 4

   131 =  ———  =  ———————

           1         4  

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

(4x+27) - (131 • 4)     4x - 497

———————————————————  =  ————————

         4                 4    

Equation at the end of step  3  :

 4x - 497

 ————————  = 0

    4    

Step  4  :

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, multiplys both sides of the equation by the denominator

Here's how:

 4x-497

 —————— • 4 = 0 • 4

   4  

Now, on the left hand side, the  4  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  4x-497  = 0

Solving a Single Variable Equation :

4.2      Solve  :    4x-497 = 0

Add  497  to both sides of the equation :

                     4x = 497

Divide both sides of the equation by 4:

                    x = 497/4 = 124.250

One solution was found :

                  x = 497/4 = 124.250

What is the value of the expression when a = -1.4 and b = -2.7? <br> |a| + b
Julli [10]
"a" is an absolute value, so that means that after whatever is in the brackets is solved as far as it can be, it becomes a positive value, no matter what it is. So, |-1.4| is equal to 1.4. The equation is 1.4+ (-2.7) or 1.4 - 2.7 which equals -1.3
