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
Let's assume length of the room as y
so the width of the room = y - 5
Area
y * (y - 5) = 750
Answer:
0.4
Step-by-step explanation:
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>
<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
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.
