Hi can someone help me with the question above?
KatRina [158]
The error is that the graph is moving up two and over one. Basically using the slop 2/1 instead of 1/2. The slope is rise/run, so it should rise up 1 unit and run 2 units to the right.

2a + 7b = 0 ⇒ 10a + 35b = 0

3a - 5b = 31 ⇒ 21a - 35b = 217

31a = 217

a = 7

2a + 7b = 0

2(7) + 7b = 0

14 + 7b = 0

7b = -14

b = -2

(x, y) = (7, -2)

Malcom coasted 32 miles from moon ridge to me tone and then pedaled back hard. If the round trip took 4 hours, what was malcoms
AURORKA [14]

Answer:

Malcom's average speed was 16 miles/hour.

Step-by-step explanation:

Given:

Distance from moon ridge to me tone = 32 miles.

Now including returned back journey.

So we can say that.

Total distance traveled = 32+32 =64\ miles

Also Given:

Time taken to travel total distance = 4 hours.

We need to find the average speed in miles per hour.

Solution:

Now we know that;

average speed is equal to Total distance traveled divided by Total time taken to travel the total distance.

framing in equation form we get;

average speed = \frac{64}{4}=16 \ mi/hr

Hence Malcom's average speed was 16 miles/hour.
