We have
In order to obtain easily the table, we need to clear y
then we evaluate for values of x
if x=0
y=-4(0)+1=1
y=1
if x=1
y=-4(1)+1=-3
y=3
if x=2
y=-4(2)+1=-7
y=-7
if x=3
y=-4(3)+1=-11
y=-11
So the table for the given equation is
x y
0 1
1 -3
2 -7
3 -11
<h3>
Answer: 20 minutes.</h3>
Work Shown:
Estimate = 1.25*(actual time)
Estimate = 1.25*(16)
Estimate = 20
Bryan estimated it would take 20 minutes.
Note: The multiplier 1.25 represents an increase of 25%
The values of the coefficient are ax^2+bx+c=
48x^2-24x+84 and A= 48, B=-24, C=84.
(4x-2)•6(2x+7)=
6•2x+ 6•7
(4x-2)(12x+42)=
4x•12x= 48x^2 4x•42= 168.
-2•12x= -24x -2•42=-84
48x^2-24x+168-84=
48x^2-24x+84=
A= 48, B=-24, C=84
ax^2+bx+c= 48x^2-24x+84.
The simplified expression of (x + y)(x - y) is x^2 - y^2
<h3>How to solve the expression?</h3>
The expression is given as:
(x + y)(x - y)
Expand the bracket
x(x - y) + y(x -y)
Further, expand
x^2 - xy + xy - y^2
Evaluate the like terms
x^2 - y^2
Hence, the simplified expression of (x + y)(x - y) is x^2 - y^2
