Step-by-step explanation:
y = -5/6x - 4
(0,-4) is the y intercept
the slope is -5/6, it descends 5 and goes 6 horizontally.
The graph of a linear function is a line
<span>
A)f(x) = -2 line
</span>
B)f(x) = x - 2 line<span>
C)f(x) = 2x </span>line<span>
D)f(x) = x</span>² parabola
So, D)f(x) = x² <span>is not a linear function</span>
The answer is -50 because -5 squared is 25 and that times 3 is 75 -5 cubed is -150 and -150 + 75 is 50
Answer:
Step-by-step explanation:
- Speed of the boat = x
- Speed of the current = y
<u>Travel downstream, speed is:</u>
<u>Travel upstream, speed is:</u>
<u>Add up the equations:</u>
- x + y + x - y = 30 + 20
- 2x = 50
- x = 25
<u>Find y:</u>
Speed of the boat is 25 mph
Speed of the current is 5 mph
Answer:
yes
