Answer:
Vertex: (-1/2, -25/4)
Focus: (-1/2, -6)
Axis of Symmetry: x=-1/2
Directrix: y=-13/2
Step-by-step explanation:
x = -2, -1, -1/2, 1, 2
y = -4, -6, -25/4, -4, 0
They are parallel to eachother
$1200+ $1400 = 2600
Answer:
1200 : 1400 = 6 : 7
The ratio is not in lowest terms so we found an equivalent ratio by simplifying.
Solution:
We can simplify the ratio 1200 : 1400 by dividing both terms by the greatest common factor (GCF).
The GCF of 1200 and 1400 is 200.
Divide both terms by 200.
1200 ÷ 200 = 6
1400 ÷ 200 = 7
Therefore:
1200 : 1400 = 6 : 7
Putting the expression in same number into both expression should yield the same answer if they are equivalent.
Gradient of the line= -1/4
equation of line: y=-1/4x + c
substitute (2,7)
c= 15/2
hence the equation is: y= -1/4x + 15/2
