How do. You solve <br> {4+3[2^3÷2
IgorC [24]

Answer:

16

Step-by-step explanation:

Simplify the following:

4 + 3×2^3/2

3×2^3/2 = (3×2^3)/2:

4 + (3×2^3)/2

Combine powers. (3×2^3)/2 = 3×2^(3 - 1):

4 + 3×2^(3 - 1)

3 - 1 = 2:

4 + 3×2^2

2^2 = 4:

4 + 3×4

3×4 = 12:

4 + 12

4 + 12 = 16:

The graphs of two linear equations ax + by = c and bx - ay = c, where a, b, c are all not equal to zero.
marin [14]
Let us find the slopes of the two lines

ax+by=c, slope m1 = -a/b

bx-ay=c, slope m2 = b/a

m1*m2 = (-a/b)(b/a) = -1

Therefore the two lines are perpendicular so the answer is D
