Answer:

You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

Solve this inequality: 3p – 6 > 21.

babymother [125]

3p - 6 > 21 <=> 3p > 21+6 <=> 3p > 27 <=> p > 27/3 <=> p > 9. So the answer is B. When solving inequalities the idea is to move the terms which contain the unknown quantity to one side and the rest of the terms to the other side. And then perform valid mathematical operations to find the interval value for the unknown quantity.

A rectangles length is 2 meters greater than its width if the e perimeter is greater than 112 what is the rectangles possible wi

pishuonlain [190]

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2(L +W)

Given L = W + 2 and the perimeter is greater than 112 meters?

P rect < 2(L +W) L = W + 2

P rect < 2(W + 2 +W)

< 2(2W+2)

112 < 4W + 4 solve for W

(112 - 4)/4 < (4W +4 - 4)/4

108/4 < (4W + 0)/4

27 < W

the width has to be greater than 27 meters

SVEN [57.7K]

Cost of painting is GHe 109,320

Given:

Floor measure = 15 m by 8 m

Cost of carpeting = GHe 890 per square meter

Total cost of painting and carpeting = GHe 216,120

Find:

Cost of painting

Computation:

Area of floor = 15 × 8

Area of floor = 120 square meter

Cost of carpeting = 120 × 890

Cost of carpeting = GHe 106,800

Cost of painting = Total cost of painting and carpeting - Cost of carpeting

Cost of painting = 216,120 - 106,800

Cost of painting = GHe 109,320
