Please help! What is the function for the graph
Evgen [1.6K]

When x = 0 the value of the function is 2 so its either A or B.

When x = 1, y = 8 so substituting these values in A we get:-

8 = 2 * 8^1 = 16 so

its Not A. Try B:-

8 = 2 *4^1 = 8 which fits

The model represents x2 – 9x + 14.
Stels [109]

Factorize the quadratic trinomial x^2 - 9x + 14 by the rule:

ax^2+bx+c=a(x-x_1)(x-x_2), \text{ where } x_1,\ x_2 \text{ are its roots. }

1. Find the roots:

D=(-9)^2-4\cdot 14=81-56=25,\ \sqrt{D}=5,\\ \\ x_1=\dfrac{9-5}{2}=2,\ x_2=\dfrac{9+5}{2}=7.

2. Factorize the polynomial:

x^2 - 9x + 14=(x-2)(x-7).

3. Only factor x-2 is given in options, then the correct choice is B.

The linear combination method is applied to a system of equations as shown.
olga_2 [115]
If you apply the linear combination method to the system like:
<span>4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Then you can be sure that the solution of all this system is: (9,3). Hope this si what you were looking for</span>

it costs $15 per month for membership at a baseball club. Members pay $5 for game tickets. Write an expression for the cost of 1
julia-pushkina [17]
Y=15+5g Y is the total cost in one month. 15 is the cost of the membership and 5 is the amount you paid to see the game. G is the variable for the amount of games. You multiple the g by 5 to get the total cost of games per a month that you went and saw. Than you add the base cost of 15 or your starting point. And you get your total cost.
