Goryan [66]

Answer:

<h2>One pound of the item will cost 4.74 bill</h2>

Step-by-step explanation:

In this problem, we are told that Delia bought 4.5 pounds of fruit

and paid with a toa total bill of 20+5= 25 bill

and also she received a  change of 3.67

this means that the item she bought cost 25-3.67= 21.33bill

now if 4.5 pounds of items cost 21.33 bill

then 1 pound will cost Xbill

cross multiply and solve for Xbill

X= 21.33/4.5

X= 4.74 bill

One pound of the item will cost 4.74 bill

photoshop1234 [79]

Answer:

g(-2) = -19

g(0) = -5

g(3) = -14

Step-by-step explanation:

  • g(-2)= -2(-2)2 + 3(-2) - 5
  • 9(-2)= -2(4) - 6-5
  • g(-2)= - 8 - 11
  • g(-2) = -19

<u>This is a quadratic function and its form is:</u>

  • g(x) = -2x² + 3x - 5

<u>Calculation of g(0) and g(3) below:</u>

  • g(0) =  -2*0² + 3*0 - 5
  • g(0) = -5

------------------

  • g(3)= -2*3² + 3*3 - 5
  • g(3) = -18 + 9 - 5
  • g(3) = -14

Write the expression (4x-2) x 6(2x+7) in the standard from of a quadratic expression, ax^2+bx+c. What are the coefficients of ea
umka21 [38]
A=48
b=144
c=-84

First, you simplify the second equation by multiplying 6 to 2x and 6 to 7.  Then, you get the two equations, (4x-2) times (12x+42).  You then use the FOIL method, multiplying 4x to 12x, 4x to 42, -2 to 12x, then -2 to 42.  Simplify.  Then number before x squared is your a value, value before x is b, and the value without x is c.
