Question

Evaluate the expression when x = 3 and y = 5.

1: 2xy
2: 6y divided by x
3:4y- x
4:Y(to the power of two) -7x +2

Answer 1

Explanation:

x = 3 and y = 5.

1: 2xy

2 x 3 x 5

=30

2: 6y divided by x

6 x 5 / 3

30/3

=10

3:4y- x

4 x 5 -3

20-3

=17

4:Y(to the power of two) -7x +2

5^2 -7 x 3 + 2

25-7x3+2

25-21+2

25-19

=6
