The answer is B. There are certain keywords that can show you what the sign will be.

"A pet store has 12 cats. If 3 of them are sold, how many cats have not been sold?" That is basically asking you to subtracted. Can you see how? "How many cats have NOT been sold." That's the key right there. so it's obviously not that one.

"A key chain can hold 3 keys. If there are a total of 12 keys, how many key chains are there?" That is asking you to divide 12 keys into key chains that can hold 3 keys. Did you take the hint?

Answer C is obvious because the phrase "In all" is addition.

And the answer isn't D either. Does this make sense?

Solve each absolute value equation and chose The correct answer from the choices provided |x|+5=18

Kamila [148]

Solve the absolute value equation.

First subtract 5 from both sides.

|x|+5=18

|x|=13

If the absolute value of x is 13 that x equals 13 and -13. Absolute value means distance from 0.

x=13,-13

What is the value of 2x – 17 when x=-3?

Maksim231197 [3]

Answer:

-23

Explanation:

To find the value of the expression when x = -3, we simply put in -3 wherever we find x - doing this gives

$2(-3)-17$ $=-6-17$ $=-23$

which is our answer!

The table shows the approximate height of an object x seconds after the object was dropped. The function h(x) = –16x2 100 models

gregori [183]

The given model would make the least sense to use for x=-2.75.

the given function is:

$h(x)= -16x^2 +100$

a quadratic relationship,

where

h is the height in feet

x is the time in seconds

<h3>what is kinetic energy?</h3>

Kinetic energy is a form of energy that an object or a particle has by reason of its motion.

as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.

h(-2.75) = $-16*(-2.75)^2+100 = -21\\$

h(0.25) = $-16*0.25^2 +100=99$ $-0.25^2*16+100=99$

h(1.75) = $-16*1.75^2+100=51$

h(25) = $-16*2.25^2+100= 19$

therefore, x=-2.75 this model would make the least sense to use
