If (x – 4) + 6 = 2 - (4 - 2x), then x =<br> A. -4<br> B. -2<br> C. 2<br> D. 4
blondinia [14]

Answer:

x=4

Step-by-step explanation:

Remove the parentheses and turn the 4-2x and make it into 4+2x candle the equal term -4 and should be left with x+6=2+2x then move the variable to the left and change the sign so it would be x-2x=2-6 and collect like terms so it would be -x=2-6 and then calculate that and get -x= -4

(sorry its alot)

4. A rock is thrown with a height equation of h = -16t2 + 64t + 5 (where h is the height of the rock in feet at any given time o
boyakko [2]

Answer:

Yes,  see below.

Step-by-step explanation:

Convert the equation to vertex form to find the maximum height:

h = -16t2 + 64t + 5

= -16(t^2 - 4t) + 5

= -16 [(t - 2)^2 - 4] + 5

= -16( t - 2)^2  + 64 + 6

= -16(t - 2)^2 + 69.

So the maximum height the rock reaches is 69 feet.

This height is reached at 2 time seconds.

Karla can buy guppies for $0.90 each at the corner pet store. If she has $13.50, how many guppies can she buy? 
pshichka [43]

All we have to do here is divide $13.50 by $0.90 to figure out how many guppies she can buy

$13.50 ÷ $0.90 = 15

Therefore, Karla can buy <u>15 guppies</u> with $13.50

Hope this helps you

Brainliest would be appreciated
