Answer:

Malcom's family travel 15 miles per hour faster than Theo's

Step-by-step explanation:

<em>See attachment for complete question</em>

Given

Malcom's Family:

d = 65t

To determine the equation of Theo's family, we refer to the attached graph.

From the graph:

t = 1; d = 50

t = 2; d = 100

First, we determine the slope, m:

m = \frac{d_2 - d_1}{t_2 - t_1}

m = \frac{100 - 50}{2- 1}

m = \frac{50}{1}

m = 50

Next, we determine equation for Theo's family using:

d - d_1 = m(t - t_1)

d - 50 =50(t - 1)

d - 50 =50t - 50

Add 50 to both sides

d - 50 +50=50t - 50 + 50

d =50t

So, we have the following:

d = 65t --- For Malcom's family

This implies that Malcom's family travel at 65 miles per hour

d =50t --- For Theo's family

This implies that Theo's family travel at 50 miles per hour

The difference between this rates is:

Rate = 65t - 50t

Rate = 15t

<em>Which implies that Malcom's family travel 15 miles per hour faster than Theo's</em>

Solve this linear system by graphing <br> x-y=6 <br> 2x=12+2y
lys-0071 [83]
You need to isolate the variables. For the first equation add x to both sides, which leaves you with y.

For the second equation, divide each side by 2 leaving you with
x= 6+y. Subtract y from each side. Subtract x from both sides. Now you have y= x + 6.

Now graph those equations.
