There are only a few roller coasters in the world whose path takes them underground. Suppose a portion of the roller coaster can

be modeled by the function f(t) = (t2 − 13t + 40)(t2 − 2t + 3), where t represents the time elapsed in seconds since passing point A on the roller coaster and f(t) represents the height in feet above the ground. What am I supposed to write on the ticket?

Find the solution to the system of equations. 4x + 3y = –1 3x – 9y = 33
alexandr1967 [171]

Answer:

Step-by-step explanation:

4x + 3y = -1         --------------(i)

3x - 9y = 33        -------------(ii)

multiply equation (i) by 3

(i)* 3     12x + 9y = -3

(ii)       <u>   3x - 9y = 33</u>

add,       15x = 30

                 x = 30/15

                 x = 2

Put x =2 in Equation (i)

4*2 + 3y = -1

8 +3y = -1

     3y = -1-8

     3y = -9

       y = -9/3

       y= -3

Likurg_2 [28]

Answer:

d =7.6

Step-by-step explanation:

(-3,11) =(x_1,y_1)\\(-6,4)=(x_2,y_2)\\\\\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\\\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\=\sqrt{\left(-6-\left(-3\right)\right)^2+\left(4-11\right)^2}\\= \sqrt{(-6+3)^2+(4-11)^2}\\ \\d= \sqrt{(-3)^2+(-7)^2} \\\\d = \sqrt{9+49}\\ \\d = \sqrt{58}\\\\d = 7.61577\\\\d =7.6

Simplify 7x + 7 + 6x - 9.<br><br> 13x - 2<br> 13x + 2<br> 11x
nikklg [1K]
To do this you must combine like terms as follows.

7x + 6x = 13x
7 - 9 = -2 

Combine these together and you will get the following.

13 - 2 or -2 +13
