The coordinates of point A on a grid are (−3, −2). Point A is reflected across the y-axis to obtain point B. The coordinates of point B are (___, −2). I need help plzz asp thx

The coordinates of point B are  (3,-2)

Step-by-step explanation:

we know that

The rule of the reflection of a point across the y-axis is given by

(x,y) > (-x,y)

so

Applying this rule to the point A(-3,-2)

A(-3,-2) > B(3,-2)

therefore

The coordinates of point B are  (3,-2)

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
