F(x) = -x+2
F(x-4) = ?
-(x+4)+2 = -x-4+2 = -x-2.
Hope this helps!
Answer:
x = 3/4
Step-by-step explanation:
f(x) = -2×2 +4x +1
f(x) = -4 +4x +1
f(x) = 4x -3
3 = 4x
3/4 = x
x= 3/4
Let's call the numbers x (the bigger) and y (the smaller)
The larger of two integers is 8 less than twice the smaller. this means:
x=2z-8
When the smaller number is subtracted from the larger, the difference

is 17.
This means: x-z=17.
i'll insert </span>
2z-8
instead of x, since it's equal to it:
2z-8-z=17
2z-z is just z:
z-8=17
so
z=25.
and x must be 25+17=42
let's check:The larger of two integers is 8 less than twice the smaller.
twice the smaller is 50, and yes, 42 is 8 smaller than 50, it's correct!
so the two numbers are 25 and 42
Answer:
m = (70-10)/(70-50) = 3 , slope
Step-by-step explanation:
m =(y2-y1)/(x2-x1) = gradient/ slope
choose any points on the graph for each x that corresponds to the y,
say choose, where x =50, y =10 (make this x1 and y1)
second step choose, another points to make Y2 and X2
where x=70, y=70, make these , y2 and x2
thus, m = (70-10)/(70-50) = 3
