Mathematics

otez555 [7]3 years ago
7 0

Answer:

I got x = 1

Step-by-step explanation:

First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:    

1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1

And since -2.5 is less than -1 this statement is true. x does in fact equal 1

Factor Completely:<br><br> 16x8−81y8
svet-max [94.6K]

Answer:

Step-by-step explanation:

16x⁸ - 81y⁸ is the difference of squares.

16x⁸ - 81y⁸ = (4x⁴)² - (9y⁴)² = (4x⁴ + 9y⁴)(4x⁴ - 9y⁴)

Note that 4x⁴ - 9y⁴ is also the difference of squares.

4x⁴ - 9y⁴ = (2x²) - (3y²)² = (2x² + 3y²)(2x² - 3y²)

16x⁸ - 81y⁸ = (4x⁴ + 9y⁴)(2x² + 3y²)(2x² - 3y²)

Sloan [31]

Answer:

Step-by-step explanation:

Step one:

given data

total money = $175

He buys 4 shirts for $24 each= 24*4= $96

The shirts are discounted 20%

2 pairs of shorts for $18 each= $36

2 pairs of pants for $22.50 each= $45

Total cost = $157.8

tax= 6%

total expenses

= 157.8+ 0.06*157.8

=157.8+9.468

=$167.268

The balance is

= 175-167.268
