55 if you mean one half
5500 if you mean 50 times 110
60 if you mean 50 from 110
Answer:
A. 9
Step-by-step explanation:
First find the slope (m) using two given pairs of values form the table, say (1, 6) and (2, 3):
Slope (m) = change in y/change in x
Slope (m) = (3 - 6)/(2 - 1) = -3/1
Slope (m) = -3
Next, substitute (1, 6) = (x, y) and m = -3 into y = mx + b and solve for y-intercept (b).
Thus:
6 = -3(1) + b
6 = -3 + b
Add 3 to both sides
6 + 3 = -3 + b + 3
9 = b
b = 9
y-intercept = 9
Answer:
A and D
If you take all the numbers and add them together they all equal and equivalence to 1.6a and 1.7d. So, if you take the numbers then add them it is A and D
The standard equation of a parabola is:
(y-k) = a(x - h)² , where h and k are the coordinates of the Vertex
Since the vertex is ( - 5 , -7), then :
(y +7) = a (x + 5)².
It's given that the vertex is a minimum, that means the coefficient a>0 and the parabola is open upward.
Depending on the value of a (always a>0) , the equation :
y = a(x-5)² + 7 is a parabola
Answer:
2x=-7y not sure tho just guessping probably wrong sorry
