inna [77]
Hello! First insert 6 where the h is located. So we have an equation that looks like the following. 6 = 2 - 18t + 16t^2

Although you could leave the equation in its original form, I am going to switch it around.
6 = 2 - 18t + 16t^2
16t^2 - 18t + 2 = 6
Move the 6 to the other side and do the math
16t^2 - 18t + 2 - 6 = 6 - 6
16t^2 - 18t -4 = 0
Factor and after factoring your T will be as follows
t = \frac{9}{16} - \frac{\sqrt{145}}{16} = -0.1900
t = \frac{9}{16} + \frac{\sqrt{145}}{16} = 1.315

13 + 2v - 8 + 6 > -7 - v please simplify and explain IN ONLY NUMBERS NO WORDS
insens350 [35]

Answer:

v > - 6

Step-by-step explanation:

13 + 2v - 8 + 6 > -7 - v (calculate the sum of difference)

= 11 + 2v>-7-v (move variable to the left-hand side and change its sign and move constant to the right-hand side and change its sign)

= 2v + v > - 7 - 11 (collect like items and calculate the difference)

= 3v>-18 (divide both sides of the inequality by 3)

=v > - 6

*in parentheses is written what to do to get the next number*
