I think the answer is 17 because the pattern adds 4 then takes away 1 so 14-1=13 13+4=17

Help<br> 1<br> A /<br> 7 (x + 2) -5 = 30

DaniilM [7]

Answer:

x = 3

Step-by-step explanation:

Given

7(x + 2) - 5 = 30 ( add 5 to both sides )

7(x + 2) = 35 ( divide both sides by 7 )

x + 2 = 5 ( subtract 2 from both sides )

x = 3

A football is kicked from the ground and follows the graph of the function y = –t2 + 3t, where y represents height and t represe

vesna_86 [32]

Answer:

The height of the objects are the same after 2 seconds.

Step-by-step explanation:

In order to calculate at which time both objects have the same height we need to find the value of t that makes both equations equal. Therefore:

$-t^2 + 3t = -t + 4\\t^2 - 3t - t + 4 = 0\\t^2 - 4t + 4 = 0\\t_{1,2} = \frac{-(-4) \pm \sqrt{(-4)^2 - 4*1*4}}{2*1} = \frac{4 \pm \sqrt{16 - 16}}{2}\\t_{1,2} = \frac{4}{2} = 2$

The height of the objects are the same after 2 seconds.

A parking garage charges an initial fee plus an hourly rate. The prices are shown in the table.

andreyandreev [35.5K]

Because it goes up for a constant rate, to find the rice for 1 hour of parking do 16.00-12.50 and get 3.50 . To find the fee, just subtract 12.5 - 3.5
The fee for parking is $9
Hope this helps
