The function is a parabola which opens downwards.
-x^2 - 2x + 15
-(x^2 + 2x) + 15
= -[(x + 1)^2 - 1 ]+ 15
= -(x + 1)^2 + 16

The domain is all real numbers and the range is {y|y <= 16}
Its the second choice.

Blababa [14]

Answer:

68°

Step-by-step explanation:

Okay, so m<8 is on the same plane as m<7 because line <em>q </em>is intersecting line <em>t  </em>and that's supposed to add up to 180° so:

180° - 112° = 68°

So, m<7 = 68°

hope this helps:)

Myesha finds some nickels and quarters under the couch cushions. How many coins does she have if she has 6 nickels and 12 quarte
Advocard [28]

If Myesha found 6 nickels and 12 quarters under her cushion, this means that she has a total of 18 coins.

<h3>What is an equation?</h3>

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the number of nickels and y represent the number of quarters. There are 2 cups in 1 pint. Hence:

If she has 6 nickels and 12 quarters:

Number of coins = 12 + 6  = 18

If she has x nickels and y quarters:

Number of coins = x + y  

If Myesha has 6 nickels and 12 quarters, this means that she has 18 coins.

How much water must be evaporated from 36 ounces of a 8% salt solution to make a 9% salt solution?
topjm [15]

Answer:

  4 oz of water must be evaporated

Step-by-step explanation:

If we let x represent the amount of water to be evaporated, the relation between the solutions is ...

  0.08 · 36 oz = 0.09 · (36 -x) oz

  0.09x = 36(0.09 -0.08) . . . . . divide by oz; add .09x, subtract .08·36

  x = 36· 0.01/0.09 = 36/9 = 4

4 ounces of water must be evaporated.
