x^2 - 7x = -12
x^2 - 7x + 12 = 0
(x - 3)(x - 4) = 0 ... see note below
x - 3 = 0 or x - 4 = 0
x = 3 or x = 4
Note: we're looking for two numbers that multiply to 12 and add to -7. Those two numbers are -3 and -4, so that's where the factorization (x-3)(x-4) comes in. After this step, you set each factor equal to zero and solve for x.
Its the first one
It is a statistical question because the data may vary for each player. :)
Find the slope which is -1/3 and add the y intercept which is 5. Feel free to check on a graphing tool like desmos
Hope this helps :D
You need 2 columns and 4 rows of data here:
Each time x increases by 1, y increases by 30, so the relationship between x and y is y = previous y + 30. This is the 3rd answer choice.
