Answer:
f(1) = -6
f(2) = -4
f(n) = f(n - 2) + f(n - 1)
=> f(3) = f(2) + f(1) = -6 + (-4) = -10
Hope this helps!

Answer: C. (10, -10)
Step-by-step explanation:
Given
1) 2x-3y=50
2) 7x+8y=-10
Multiply both sides of 1) equation by 3.5
1) 3.5(2x-3y)=3.5×50
7x-10.5y=175
2) 7x+8y=-10
Subtract 2) equation from the 1)
(7x-10.5y)-(7x+8y)=175-(-10)
-18.5y=185
y=-10
x=10
(10, -10)
Hope this helps!! :)

Answer:
He will need to sleep 5.77 hours
Step-by-step explanation:
The first night, he slept 3 percent more than the previous night, meaning 5.28 + (5.28 x 3/100) = 5.28 + 0.1584 = 5.4384
The second night, he will need to sleep 3 percent more than the previous night, meaning 5.4384 + (5.4384 x 3/100) = 5.4384 + 0.163152 = 5.601552
The third night, he will need to sleep 3 percent more than the previous night, meaning 5.601552 + (5.601552 x 3/100) = 5.601552 + 0.16804656 = 5.76959856 = 5.77

Answer:
x=-5
Step-by-step explanation:
Denominators are:
x+5, 5, and 5x+25
5 cannot be turned to 0 since it does not have a variable.
So we have x+5 and 5x+25.
eqyal each denominator to 0 since that is what we want.
x+5=0 5x+25=0
x=-5 5x=-25
x=-25/5
x=-5
∴x=-5 for all denominators to make 0.
