Answer:
f(x) = -3x + 12
Step-by-step explanation:
The chart could be represented like this:
x y
0 12
1 9
2 6
3 3
Suppose that f(x) = y
And substitute x values.
y = -3x + 12
"x = 0"
y = -3(0) + 12
y = 0 + 12
y = 12
"x = 3"
y = -3(3) + 12
y = -9 + 12
y = 3
From the results, it corresponds to the function.
Answer:
3d - 4f
Step-by-step explanation:
(12d + 28f) - 5f - (27f + 9d)
12d + 28f - 5f - 27f - 9d
(12-9)d + (28-5-27)f
3d - 4f
don't forget to put bracket, it is fundamental
Answer:
y=x
Step-by-step explanation:
As you can see from this graph, all of the x and y coordinates are the same, so it would only make sense for x and y to be equal.
Answer:
x= -6
Step-by-step explanation:
17=-2x+5
17-5=-2x+5-5
12= -2x then divided both side by -2
-6=x
Answer:
slope=-3
y=-3x+5
Step-by-step explanation:
use two given points (3,-4)(0,5)
5- -4= 9
0-3=-3
9/-3=-3
