f(5) = 0.5^(5-1)*f(1) = 0.5^4 * 120 = 7.5
1. 6.5, 2. 22.4, 3. 10 and 11, 4. 6 and 7, 5. between 8 and 9 but closer to 8
-1.1-1.9, 1.9,1.1,2.1,-3.9,3.-9,-2.-1
Answer:
B
Step-by-step explanation:
First label the equations.
6x +3y= 18 -----(1)
y= -2x +5 -----(2)
subst. (2) into (1):
6x +3(-2x +5)= 18
6x +3(-2x) +3(5)= 18 (expand)
6x -6x +15= 18
15= 18 (simplify)
(reject)
There is no solution.
<u>Further explanation</u><u>:</u>
If I rewrite the first equation into the form of y=mx+c, I would get
6x +3y=18
3y= 18 -6x (bring y term to one side)
y= 6- 2x (÷3 throughout)
y= -2x +6
Notice that the gradients of both lines are equal ( -2). This implies that they are parallel to each other and will never meet. Hence there are no solutions.
