Answer: 10 : t = 16 11 : x = -8 13 : x = 0
Step-by-step explanation: Im sure about 10 and 11 but not too sure about 13 and explanations are too hard for me to explain
Answer: 129
Step-by-step explanation:
the mean is the average of the data. including x, there are 6 data points
average = total/6
average = (98 + 123 + 105 +114 +109 + x) / 6
113 = (98 + 123 + 105 +114 +109 + x) / 6
113 = (549+ x) / 6
678 = 549 + x
x = 129
It should be y=2x-3 since it’s touching -3 on the y axis and the it’s going 2 units up and 1 to the right, making the slope = 2.
Answer:
x^2+x + 1/4
Step-by-step explanation:
x^2+x
Take the coefficient of x
1
divide by 2
1/2
Square it
(1/2)^2 = 1/4
Add this to make a perfect square trinomial
