The answer is b because when you add in the scale factor of 3 it makes all of the coordinates 3 times larger (for example -4 * 3 = -12 and 3 * 3 = 9 so P" = (-12, 9))

Devon set out to bicycle from Exeter to the beach, a distance for 10 miles. After going a short while at 15 miles per hour, the

enyata [817]

Answer:

Distance between Exeter and the point where flat tire occurred was 1.875 miles.

Step-by-step explanation:

Let the distance of Exeter and the point where bike developed the flat tire was = x miles

Then time taken to reach that point with speed 15 mi per hour = $\frac{\text{Distance traveled}}{\text{Time taken}}$

= $\frac{x}{15}$ hours

Devon comes back with a speed of 3 miles per hour then time taken to come back = $\frac{x}{3}$ hours

Total time for the entire episode = 48 minutes or $\frac{3}{4}$ hours

Therefore, $\frac{x}{15}+\frac{x}{3}=\frac{3}{4}$

$\frac{x+5x}{15}=\frac{3}{4}$

$\frac{6x}{15}=\frac{3}{4}$

x = $\frac{3}{4}\times \frac{15}{6}$

x = $\frac{15}{8}$ miles

x = 1.875 miles

Therefore, distance between Exeter and the point where flat tire occurred was 1.875 miles.

Consider the system of equations:

vodka [1.7K]

Answer:

(x, y) = (5, 1)

Step-by-step explanation:

To <em>eliminate</em> x, you can double the second equation and subtract the first.

... 2(x +4y) -(2x -3y) = 2(9) -(7)

...11y = 11 . . . . . simplify

... y = 1 . . . . . . divide by 11

Using the second equation to find x, we have ...

... x + 4·1 = 9

... x = 5 . . . . . subtract 4

_____

<u>Check</u>

2·5 -3·1 = 10 -3 = 7 . . . . agrees with the first equation

(Since we used the second equation to find x, we know it will check.)
