A map uses a scale of 1 in. : 20 mi. If the distance between two cities on the map is 1.5

IceJOKER [234]

So we know 1 in on a map is 20 miles in real life (irl).

So we can multiply whatever distance on the map, by 20:

1.5 * 20 = 30 miles.

Solve the following system of equations by the substitution method.

ruslelena [56]

5x = y + 6 (I)
2x - 3y = 4 (II)
-------------------
We have:
5x = y + 6 → $x = \frac{y+6}{5}$

Soon:
2x - 3y = 4 → $2* (\frac{y+6}{5}) - 3y = 4\to \frac{2y+12}{5} - 3y = 4$
<span>least common multiple (5)
</span> $\frac{2y+12}{5} - 3y = 4\to \frac{2y+12}{\diagup\!\!\!\!\!5} - \frac{15y}{\diagup\!\!\!\!\!5} = \frac{20}{\diagup\!\!\!\!\!5}$
$2y + 12 - 15y = 20$
$- 15y + 2y = 20 - 12$
$- 13y = 8$
$\boxed{\boxed{y = - \frac{8}{13} }}\end{array}}\qquad\quad\checkmark$

The center of a circle is at (4,-3) and it’s radius is 3 units, which point lie on the circle

sergey [27]

Answer:

Any set of (x , y) whose distance from (4, -3) is 3 units lies on the circle.

Step-by-step explanation:

To find the distance , use the formula

$distance = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}$

If distance < 3, (x, y) lies inside the circle.

If distance > 3, (x, y) lies outside the circle.

If distance = 3 (x, y) lies on the circle.
