A bag contains white marbles and yellow marbles, 46 in total. The number of white marbles is 1 more than 4 times the number of y
Mrrafil [7]

Answer:

There are 37 white marbles.

Step-by-step explanation:

Let the white marbles be represented as w.

Let the yellow marbles be represented as y.

The bag contains both white marbles and yellow marbles which add up to 46 marbles. This means that:

y + w = 46 ___________(1)

The number of white marbles is 1 more than 4 times the number of yellow marbles. This means that:

w = 1 + 4y ___________(2)

First, we find y by putting (2) in (1), thereafter, we find w:

=> y + 1 + 4y = 46

y + 4y = 46 - 1

5y = 45

y = 45 / 5 = 9 marbles

=> w = 1 + 4(9)

w = 1 + 36 = 37 marbles

There are 37 white marbles.

Reflection across x=-2​
BartSMP [9]
The reflection of the point (x, y) across the y-axis is the point (-x, y). When you reflect a point across the line y = x, the x-coordinate and the y-coordinate change places. Notice how each point of the original figure and its image are the same distance away from the line of reflection (x = –2 in this example).
