F(x) = -2 * x + 8
f(-1.8) = -2 * (-1.8) + 8 = 3.6 + 8 = 11.6
The coefficient (letter chosen) that is used does not matter as it is only to show that it is an unknown variable, if you have more than one variable you need more than one type of coefficient (use different letters for different ones you dont know).
Answer:
Amount on 11% note = $106,666.67
Amount on 8% note = $43,333.33
Step-by-step explanation:
Let the amount for the short-term note at 11% interest be x.
Thus, the amount for the short-term note at 8% interest will be (150000 - x)
Now we are told that the total interest paid is $15,200.
Thus;
0.11x + 0.08(150000 - x) = 15200
0.11x + 12000 - 0.08x = 15200
Rearranging gives;
0.03x = 15200 - 12000
0.03x = 3200
x = 3200/0.03
x = $106666.67
Thus, amount for 8% note = $150000 - $106666.67 = $43,333.33
Step-by-step explanation:
Percentage for Rollerblading
= Total - Percentage for Swimming - Percentage for Biking
= 100% - 43% - 15%
= 42%.
Answer:
A
Step-by-step explanation:
The volume (V) of the triangular prism is calculate as
V = area of triangular face × depth
area of triangle = 0.5 × 9 × 4 = 0.5 × 36 = 18 units², thus
V = 18 × 15 = 270 units³ → A
