A.) Hobbs:

We know that the dependent variable goes on the y axis and that the independent variable goes on the x axis. In this case, the cost changes according to the number of hours, so x = hours and y = cost. SInce it states that both of the relationships are linear, this means that we should look for a slope equation: y = (slope) * x + (y intercept).

We begin with y2 - y1/x2 - x1. In this case, the x value changes by a value of 0.5 and the y value changes by 17, making our slope 17/0.5, or 34.

Now that we know the m value, write down the equation y = 34x + b, and plug in the values you already know. For instance, if we use the first pair:

25 = 34 * 0.5 + b

25 = 17 + b, which means b = 8. Your equation for this is y = 34x + 8.

McGee:

Using the same method, 144 - 80/4 - 2 = 64/2 = 32.

y = 32x + b

80 = 32 * 2 + b, so b = 16.

Now let's plug in the x values.

Hobbs: y = 34(3) + 8, so y = $110

McGee: y = 32(3) + 16 = $112

Therefore, the customers should go to Hobbs for 3 hour mule rides, since it's less expensive.

B.) Yes. this would affect the answer to part A. Since the x value has changed, the y value would also have to change for the equation to be true. FOr instance:

34(5) + 8 = $178

32(5) + 16 = $176

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
