Answer:
-2 and 24
Step-by-step explanation:
the trend line is linear,
let the unknowns be A and B
hence the equation becomes
K = AJ + B
from the graph we can see the following:
when J = 0, K = 24 (substitute this into the equation)
K = AJ + B
24 = A(0) + B
24 = B (Answer)
Also notice that when K = 0, J = 12
together with our previous finding that B = 24, the equation becomes:
K = AJ + B
0 = A(12) + 24
12A = -24
A = -24 / 12
A = -2 (answer)
ADC = 40 + 30 = 70 degrees
DBC is given at 45 deg
AEB = 100 degrees, vertical angle from intersecting lines
BCD = 50 + 50 = 100 degrees
Answer:
f(2) = -5
Step-by-step explanation:
For this problem, we are evaluating the graph of f(x), meaning at the value of x, we want the y-value.
Note, when x = 2 on the graph, the only y coordinate available is y = -5.
Hence, when we evaluate f(x) for x = 2, we get y = -5. f(2) = -5.
Cheers.
