Answer:
1= 10
2= -5
3= 1
Step-by-step explanation:
Keep change opposite is what I use for number 1
For 2 just subtract 8 - 3
5 will be the answer and since 8 was negative it will be negative 5 cause 8 is the bigger number.
for 3
6-5 is simple.
Answer:
y = -x - 7
Step-by-step explanation:
As we move from the point (3, -4) to the point (5, -6), x increases by 2 and y decreases by 2. Thus, the slope of this line is m = rise / run = -2/2, or -1.
Starting with the general slope-intercept form of the equation of a straight line, we get y = mx + b => y = -1x + b.
Subbing -4 for y and 3 for x, we get
-4 = -1(3) + b, which yields b = -1
Thus, the desired equation is
y = -x - 1
The answer is C ... or you could say n<3
F(x) = x^2 + 1
f(4) = 4^2 + 1 = 16 + 1 = 17
2*f(4) = 2 * 16 = 32
