I will give brainliest.........................Please explain please..........................

<h3>Answer:  Profit = 6.40 dollars</h3>

======================================================

Explanation:

Plug x = 80 into the equation to get

y = 0.12x

y = 0.12*80

y = 9.60

This means the store paid $9.60 for the rope. This amount of money is leaving the store owner's wallet or bank account. We'll keep this in mind for later.

-------------------

The graph shows the equation y = 0.20x

Note how the point (1, 0.20) is on the line to help see the slope right away. This trick only works when the line goes through the origin.

You could also use the slope formula to get this. The y intercept is 0 since the line goes through the origin.

This equation and graph show that the price per foot is $0.20, or it's 20 cents per foot.

Plug in x = 80 to find how much the store will make in revenue

y = 0.20x

y = 0.20*80

y = 16

The store makes $16 in revenue when it sells 80 ft of rope.

----------------------

The cost to the store was $9.60 found in the first section. The revenue was $16 found in section 2.

So,

profit = revenue - cost

profit = 16 - 9.60

profit = 6.40 dollars

Answer:

It takes him  hours to mow the third lawn

Explanation:

We are given that Evan takes  hours to mow Mr. Gals lawn and  hours to mow Mrs. Lee's lawn

This means that:

Time taken to mow the two lawns =  hours

Now, we are given that the time taken to mow the three lawns is  hours

This means that:

Time taken to mow the third lawn =  hours

Hope this helps :)

What is the discontinuity and zero of the function f(x) = 3x^2 + x - 4 / x-1
7nadin3 [17]
Ans: Option (1) <span>Discontinuity at (1, 7), zero at ( negative four thirds , 0) 
</span>
Explanation:
Given function:
f(x) =  \frac{3x^2 + x - 4}{x-1}

Now if we plug in the x = 1, we would have discontinuity as function goes to infinity.

Now for f(1):
f(x) = \frac{3x^2 + x - 4}{x-1} \\ f(x) = \frac{3x^2 + 4x - 3x - 4}{x-1} \\ f(x) = \frac{x(3x+4)-1(3x+4)}{x-1} \\ f(x) = \frac{(x-1)(3x+4)}{(x-1)} \\ f(x) = 3x+4 \\ now ~ insert ~ x=1: \\ f(1) = 3(1) + 4 = 7 \\ It~means~discontinuity~at~(1,7).\\ Now~let~us~find~zeros.\\ put~ f(x) = 3x+4 ~ equals~ to ~zero. \\ =\ \textgreater \ ~3x+4 = 0 \\ =\ \textgreater \  ~ x =  \frac{-4}{3} \\ Hence~zeros=(  \frac{-4}{3}, 0)
