Answer:

D. -2x + 2y = 1

Step-by-step explanation:

When the line is given in standard form:

ax + by = c, it has slope of -a/b

Given line:

4x + 4y = 3

It has a slope:

m = -4/4 = -1

A line perpendicular to the given should have a slope m = 1 as negative reciprocal to the given

Let's see which line has the slope of 1:

1. m = -(-1)/6 = 1/6 - NO
2. m = -4/4 = -1 - NO
3. m = -2/4 = -1/2 - NO
4. m = -(-2)/2 = 1 - YES

Correct option is D

SpyIntel [72]

Answer:

The quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2

Step-by-step explanation:

Given:

32 ÷ 4 + (fraction 1 over 2 x 16) − 2.

32/4 + (1/2 * 16) - 2

32 times 4 plus fraction 1 over 2 times 16, then subtract 2

32 divided by 16 added to fraction 1 over 2 plus 4, then subtract 2 Half of 16 divided by 4 plus 32, then subtract 2

The quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2

The statement which describes the situation is:

The quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2
