Answer : 2.5
Solution:
To find the halfway number it means that you need to find the middle most value using the formula
Mid value = (X + Y) / 2
So in this case it would be,
Mid value = (-15 + 20 ) / 2
Mid Value = ( 5 ) / 2
Mid Value = 2.5 answer
Hope this helps in understanding the question! :)
Note : do not forget the negative sign as it will change the answer and may cost you marks!
Answer:
y = -3x + 1
Step-by-step explanation:
Starting with the point (-1, 4) and the slope m = -3, write out the point-slope equation of a straight line: y - k = m(x - h) becomes y - 4 = -3(x + 1), or:
y = -3x - 3 + 4
y = -3x + 1 This is the same as answer choice (b).
The answer to your question is option d as x is positive ( making it open up), and the vertex is (-3,-4)
The missing side would be B = 15
