Answer: x = -3

Step-by-step explanation:

1. 2x + 3 + 7x = -24 (combine like terms, 2x + 7x)

2. 9x + 3 = -24 (subtract 3 from both sides of the equation, inverse operations)

3. 9x = -27 (divide -27 by 9 from both sides, inverse operations)

4. X = -3 (-27 divided by 9 is equal to -3, a positive divided by a negative is a negative)

Naddika [18.5K]

Answer: $5

Step-by-step explanation: This can be represented by the equation

40 + 12T = 25 + 15T

We just solve for T.

Subtract 12T from both sides

40 = 25 + 3T Subtract 25

15 = 3T Divide by 3

5 = T

A football is kicked into the air. The height of the football can be modeled by the equation

Alinara [238K]

Answer:

x = 0 and x = 1

Step-by-step explanation:

Given that,

A football is kicked into the air. The height of the football can be modeled by the equation :

$h = -16x^2 + 16x$

Where

h is the height reached by the ball after x seconds

When it touches the ground, h = 0

So,

$-16x^2 + 16x=0\\\\16x(-x+1)=0\\\\x=0\ and\ x=1$

So, it will touch the ground at x = 0 and x = 1 seconds.
