Step-by-step explanation:

72÷9= 8, so the boat was only doing 8mph going upstream (against the current) the return trip downstream only took 4 hours. 72÷18=4 meaning the boat was traveling at 18mph downstream (no current) there is a 10mph difference between upstream and downstream therefore the current had to be running at 10 mph. so the speed of the tug boat is 8mph without a current and the current is running at 10mph.

Radical 6x^2 multiplied by radical 18x^2
Alina [70]

Does radical mean square root?, because radical can mean square root, cube root, fourth root, etc.


Well, I'm going to assume that radical = square root

So, if you have two square root functions, you can multiply the numbers within the square root, so you now have \sqrt{48x^4}, which I'm not sure if you want it simplified or not

Write an equation of the line in slope-intercept form: y-intercept of 2, x-intercept of 4
zvonat [6]

Answer:

\sf y=-\dfrac12x+2

Step-by-step explanation:

y-intercept is when x = 0, so (0, 2)

x-intercept is when y = 0, so (4, 0)

\sf slope=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{0-2}{4-0}=-\dfrac12

Slope-intercept form of linear equation:  \sf y=mx+b

(where m is the slope and b is the y-intercept)

Given:

  • \sf m=-\dfrac12
  • b = 2

\sf \implies y=-\dfrac12x+2

Answer:

B. 4

Step-by-step explanation:

The sign \geq means greater than or equal to

The sign > just means greater than

4 is a solution for x \geq4, because 4 is equal to 4, but not a solution for x>4, because 4 is not greater than 4

Hope this helps! :)
