(-2.-1). You can just plug in the numbers. -1=-6+5 is -1=-1. -1-2(-2)=3 is -1--4=3 is 3=3.
Answer:
Step-by-step explanation:
The given quadratic function is f(x)=2(2x^2+4x)+3
Multiplying through to open the brackets,
f(x)=4x^2 + 8x +3
To find the zeros, we will equate
f(x) = 0
Therefore,
4x^2 + 8x +3 = 0
Finding two numbers such that when we multiply them, it gives us 12xx^2 and when we add them, it gives us 8x, we have 6x and 2x. Therefore,
4x^2 + 8x +3 = 0 is expressed as
4x^2 + 2x + 6x +3 = 0
2x(2x + 2) +3(2x + 3) = 0
(2x +2)(2x +3) =0
f(x) = 2x +2)(2x +3)

Answer:
745.31+50.60w=1,099.51
W=7
Step-by-step explanation:
1st subtract 1099.51 from 354.20
2nd use your answer which is 745.31 and add that with how much she plans on saving for how ever long
3d to find out how many weeks which is 50.60*w you need to first minus 745.31 from both sides
4th so 745.31- 745.31 and 1099.51-745.31 =354.2 or .20
5th divide 354.2 by 50.60 =7
So overall w= 7
Answer:
C
Step-by-step explanation:
An undefined slope means that the line is vertical and parallel to the y- axis.
A vertical line has equal x- coordinates of the points it passes through.
The only pair where the x- coordinates are equal are
(- 3, - 3) and (- 3, 3) ← undefined slope → C
