3 < -5n + 2n

Simplify.

3 < -3n

Divide both sides by -3.

*Remember, when multiplying and dividing by negatives, you must change the sign.

-1 > n OR n<-1

~Hope I helped!~

The inequality would be the negative factor, because -5n+2n is 3n. You would write it on a number line like this.....

That's not true. 56 is 10 more than 46. 46 +10 is 56.

One integer is 5 less than another and their product is 84. Find the integers.
andrezito [222]

The first integer is going to be x and the second one is going to be y.

We now turn the clues into equations:

x = y - 5

xy = 84

The substitution method:

(y - 5)y = 84

y^2 - 5y - 84 = 0

(y+7)(y-12) = 0

y = -7, 12.

If y = -7, then x = -12.

If y = 12, then x = 7

On a hot day, a fan has a mark on the tip of one blade. The equation y
stellarik [79]
<h3>Answer:  5 cm</h3>

===================================================

Explanation:

Recall that the range for cosine is from -1 to 1, including both endpoints. The smallest cosine value is what we're after, since we want the height to be as small as possible (to allow the blade be closest to the table).

Effectively, this means we replace the cos(x) with -1 so that it's as small as possible. Then we compute to get:

20*cos(x)+25

20*(-1) + 25

-20 + 25

5

The height of the fan tip is 5 cm when it is the closest to the table.

Side note: On the flip side, the furthest away the fan tip can get is 20*(1) + 25 = 45 cm. Therefore, the range of y values is 5 \le y \le 45

Answer:

  F.  30·tan(52°)

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between the opposite and adjacent sides in a right triangle.

  Tan = Opposite/Adjacent

  tan(52°) = BD/DL

  BD = DL·tan(52°)

The boat-to-dock distance is ...

  30·tan(52°) . . . . matches F
