What is the domain of f?

2 answers:

7 0

Well what you have to see here is where the lowest our x gets to and that is -7. Next we would want to find the highest x value that the graph gets to which is 7. The domain would be (-7, 7).

Kevin can carry a basket 5 feet Rachel can carry it three feet farther than Kevin Daniel can carry the basket half as far as Rac

OlgaM077 [116]

Yes. Kevin can carry the basket 5 ft. Rachel can carry it 3 feet more than Kevin (5+3=8). Daniel can carry the basket half the length of Rachel (8/2=4). The total distance they can carry the basket is 5+8+4=17. 17 is greater than 15, so yes they can carry it 15 feet.

Graph the line of the equation 8x/5 - 2y = -8 using its slope and y-intercept

satela [25.4K]

Answer:

$y=\frac{4}{5}x+4$

Step-by-step explanation:

You'll need to get this equation in slope-intercept form by solving for y. I do a little extra here to get it in the correct form, but I think it's pretty clear. Let me know if I need to clarify.

$\\\\\frac{8x}{5}-2y=-8\\\\-2y=-\frac{8x}{5}-8\\\\2y=\frac{8x}{5}+8\\\\y=\frac{4}{5}x+4$

Once it's in slope-intercept form, both the slope and the y-intercept are readily available so you can easily graph it. I graphed both of them in the attached image so you can see that they are the same line.
