10x-20
Step-by-step explanation:
(5×2x)-(5×4)
10x-20
Answer:
20 is right
Step-by-step explanation:
to easy I know maths
I believe you may have the order incorrect. If we were looking at g(f(x)) the answer would be 47. We would get this by sticking the 3 in for x in f(x) and solving, which would give us 48. We would then stick that answer in for x in the g(x), giving us 47.
In its current order the answer would be 28.
Slope formula = y2 - y1/ x2 - x1
SF = 3 - (-3)/ 2 - 5
SF = 6/ -3
Slope = -2
Now we need to find b (the y-intercept)
y = mx + b
y = -2x + b
3 = -2(2) + b
3 = -4 + b
+4 +4
7 = b
The equation of the line should be:
y = -2x + 7
