Answer:
Step-by-step explanation:
f(x) = -x + 71 - 4 is a straight line. It does not have a vertex.
40hrs/5days a week= 8hrs a day
£14x8=£112 a day
112x5= £560 a week
560x4= £2240 gross monthly income
Take 1/2 of 1 and square it and add to both sides
1/2 squared=1/4, add to both sides
x^2+x+1/4=19/4+1/4
factor perfect square
(x+1/2)^2=20/4
(x+1/2)^2=5
square root both sides
x+1/2=+/-√5
minus 1/2 both sides
x=-1/2+/-√5
x=-1/2+√5 or
x=-1/2-√5
B is answer
If 4 < b < 5, then -4 > -b > -5, or -5 < -b < -4.
Then
3 < a < 4 ==> 3 - 5 < a - b < 4 - 4 ==> -2 < a - b < 0
Answer: If you plot a point in the y-axis at -6, you can plot two more points by using the slope "rise over run" Then draw a line connecting the points.
The coordinate of the y intercept is (0.-6) To find the first x values of the first 2 coordinates, add 1 then 2 to 0. To find the y values, add 2 then 4 to the -6
Step-by-step explanation:
From -6 go up 2 over 1 and plot at (1, -4 ) then up 2 over 1 again to (2, -2)
The x- intercept will be at (3,0)
