Answer:

b

Step-by-step explanation:

When the object hits the ground , the h = 0 , that is

- 16t² + 54 = 0 ( subtract 54 from both sides )

- 16t² = - 54 ( divide both sides by - 16 )

t² = \frac{54}{16} ( take square root of both sides )

t = \sqrt{\frac{54}{16} } ≈ 1.84 seconds ( to 2 dec. places )

The correct question in the attached figure

Let
x-------------> <span>the number of granola bars 
y-------------> the pounds of fruit

we know that

if 12 bars------------> cost $12
 1 bars--------------> X
X=12/12---> x=$1
1 bar---------> cost $1

if 9 pounds of fruit----------> cost $36
 1 pound-------------------> X
X=36/9--------> x=$4
1 pound -------> cost $4

</span><span>expression for the total cost=(1)*x+(4)*y----------> x+4y
</span><span>x=12
y=9
then
</span>the total cost=12+4*9----- $48

<span>an inequality that compares
the total cost with the amount you have to spend is
x+4y<=48
</span>
using a graph tool see the attached figure

<span>the inequality that models the number of granola bars you need to buy is

Help me solve this problem please
BabaBlast [244]

Answer:

x=-10

Step-by-step explanation:

15-2(x+5)=25

multiply the 2 by the x and 5 and you get

15-2x-10=25

since the 15 and the negative 10 are on the same side you add them together and get

5 -2x= 25

-5       -5

-2x =20

Then divide the -2/20= -10
