Y = - 5 x + 10
A ) x = - 15, y = 5
5 = 75 + 10
5 ≠ 85
B ) x = 2, y = 0
0 = - 5 · 2 + 10
0 = 0 ( correct )
C ) x = - 1, y = - 5,
- 5 = 5 + 10
- 5 ≠ 15
D ) x = 3, y = 25
25 = - 15 + 10
25 ≠ - 5
Answer:
B ) ( 2, 0 )
Answer:
Step-by-step explanation:
The way I did this was I noticed that the graph had a y-intercept of 4 and the only exponential function that had a y-intercept of 4 was
<span>If the base rate of Taxation percentage is only 8%, and the item in question that is being taxed costs $30, then the answer of how much the tax will cost ends up being 8% of 30. 8% of 30 is 2.4 so 8% of $30 is $2.40. So the cost of the $30 item, including tax, is $32.40.</span>
Answer:
i think its x= 0.75
Step-by-step explanation:
substitute:
8x × 5 = 40x
8x × 10 = 80x
8 × 5 = 40
5 × 10 =50
40x + 80x = 40 + 50
add like terms
so it'd be:
120x = 90
now divide 90 by 120 and that would give you the value of x alone which is 0.75
For odd functions f(-x) = -f(x).
Given that f(x) = 3sin(x)
f(-x) = 3sin(-x) = -3sinx = -f(x).
Therefore, f(x) = 3sin(x) is an odd function.
