A marine biologist needs to put a GPS device underwater, halfway between two tracking stations to help document great white shar
Akimi4 [234]

The location of the GPS device will be ( 75,-45).

<h3>What is coordinate geometry?</h3>

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

The given coordinates of the stations are ( -50,-25) and (200,-65).

The midpoints for the two coordinates will be calculated by the formula given below:-

\rm Mid points= (\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})

\rm Midpoint= \dfrac{-50+200}{2},\dfrac{-25-65}{2}

\rm Midpoint =\dfrac{150}{2},\dfrac{-90}{2}

Midpoints = 75, -45

Therefore the location of the GPS device will be ( 75,-45).

Which is the solution to the inequality?
n200080 [17]

y < –12

Solution:

Step 1: Given inequality is y + 15 < 3.

To find the solution to the inequality.

Step 2: Subtract –15 on both sides to equal the expression.

⇒ y + 15 –15 < 3 –15

Step 2: Using addition identity property, any number adding with zero gives the number itself.

⇒ y + 0 < –12

⇒ y < –12

Hence the solution to the inequality is y < –12.
