Answer:
f(x) = (x-8) -5
My original answer was correct.
Answer:
B
Step-by-step explanation:
look at the graph, it is really easy with such basic numbers involved :
the red dotted line is
y = 2
since the line is dotted (= the points on the line are not included in the solution), the colored area is below the line is
y < 2
the blue line is clearly just a 45° basic line through the origin (0,0), and that means for every point in that line x is equal to y.
y = x
and the line is solid, so the points are included in the solution. the shaded area is above the line, so, we need to use the ">" relation :
y >= x
the required solution is the combination of both, and therefore, B is correct.
Answer:
P = 14.9
Step-by-step explanation:
i used distance formula:
d = √(difference of y-values, squared, + difference of x-values, squared)
distance from (-2,1) and (2,4):
= 5
distance from (-2,1) and (-1,-2): 
distance from (-1,-2) and (2,4):
= 3
P = 5 +
+ 3
≈ 14.9
Answer:
Let Ishaan's age be x. Then, Christopher's age is x-20. These are their current ages.
14 years ago,
x-14 = 3(x-20-14) (we need to subtract 14 from both of their ages')
x - 14 = 3(x - 34)
x - 14 = 3x - 102
2x = 88
x = 44
Ishaan is 44 years old now.
The correct answer would be A.
We can immediately eliminate C and D because they have the slope listed as 2 rather than -2.
Because we're looking for the line that passes through (1, 5), we know that the y-intercept has to be 7, because from (0, 7) we get to (1, 5) when we apply the slope of -2.
Thus, the answer is A.
