Mischa wrote the quadratic equation 0 = –x2 + 4x – 7 in standard form. What is the value of c in her equation
Zolol [24]

Mischa wrote the quadratic equation 0 = –x2 + 4x – 7 in standard form

The standard form of quadratic equation is

y= ax^2 + bx + c

When y=0 then the standard equation becomes

0= ax^2 + bx + c

Now we compare the given equation 0 = -x^2 + 4x - 7  with 0= ax^2 + bx + c and find the value of a, b,c

-x^2 can be written as -1x^2

0= ax^2 + bx + c

0 = -1x^2 + 4x - 7

a= -1 , b=4  and c=-7

The value of c is -7

They're just hired a new employee to work in your bike shop in one hour the employee burns 55 chocolate chip cookies if this rep
KATRIN_1 [288]

Answer:

250 cookies

Step-by-step explanation:

The employee burns 55 chocolate chip cookies

if this represented 22% of the days production

Let x = the total production of cookies for the day

how many cookies did you plan on producing that day?

22% of x = 55

22 / 100 * x = 55

0.22x = 55

Divide both sides by 0.22

x = 55 / 0.22

= 250

x = 250 cookies

Therefore, the total production of cookies for the day is 250
