Answer:
Step-by-step explanation:
1) r = 5mm; d = 10 mm
2) r = 6 cm; d = 12 cm
3) r = 9 m; d = 18 m
4) r = 8 km; d = 16 km
5) r = 11 m; d = 22 m
6) r = 15 mm; d = 30 mm
7) r = 13 km; d = 26 km
8) r = 7 cm; 14 cm
Answer:
B. y = -x + 2
Step-by-step explanation:
Now, the standard slope formula is y = mx + b, where m is the slope and b is the y intersect. From the graph pictured, we know that it has a slope of 1 since it goes up one point and to the right one point. So, I know the equation of this line is y = x + 2. Now, all that is left is to find this equation with a -x, which indicates that it is a -1 slope. Since option B has the formula y = -x + 2, that is the correct answer.
You gotta remember that
means
.
So, in this case, f(x) is [4x - 3], g(x) is [x^3 + 2x].
So that : f(x)-g(x) = [4x-3] - [x^3+ 2x] = -x^3 + 4x - 2x - 3 = -x^3 + 2x - 3
