Answer:
sorry idk
Step-by-step explanation:
you know that (0,3) is a point and (1,1) is another point.
so now you have to replace them in the follow equations.
i did that and the right answer is the first equation => y=-2x+3
The correct answer is 10/15, simplified to 2/3.
Answer:
<em>The answer to your question would be D.</em>
<em>D. Range: 20</em>
<em>Mean: 10</em>
<em>Median: 9</em>
<em>Mode: none</em>
Step-by-step explanation:
1, 2, 3, 8, 9, 12, 14, 20, 21
Range: 21 - 1 = 20
Mean: 1 + 2 + 3 + 8 + 9 + 12 + 14 + 20 + 21 = 90/9 = 10
Median: 9
Mode: there are no mode in the following given data set.
Equation for parabola is
y = a ( x - h ) ^2 + k where (h,k) is the vertex of the parabola.
Given: vertex (-4, -1) h = -4; k = -1
y = a (x - (-4))^2 + (-1)
y = a ( x + 4)^2 - 1 plug in the values given for x and y. y-value is 0 and x-value is 2
0 = a (2 + 4)^2 -1
0 = a (6)^2 -1 square 6
0 = a 36 - 1 add 1 to both sides to isolate the a
1 = 36 a divide both sides by 36 to isolate the a
1/36 = a the coefficient.
i think you might have typed a number incorrectly if those are your answer choices. Maybe the step by step process can still help you with your correct numbers. :-)
