Answer:
D = 1/2 , E = -1/2 , F = -5/2
Step-by-step explanation:
vertical parabola : ( 1,-2), ( -3, 10 ), (4, 31 )
General form ; 
( 1 ,-2 ) = x1, y1
( -3, 10 ) = x2, y2
( 4, 31 ) = x3, y3
hence :
attached below is the detailed solution required
D = 1/2 , E = -1/2 , F = -5/2
Answer:
4; y-5=2(x+3)
Step-by-step explanation:
Question 1: 8y-18=14
8y=32
y=4
Question 2: y-5=2(x-(-3)
y-5=2(x+3)
Answer:
3,333...
Step-by-step explanation: U can do a rule of three
4 ---- 1
x ---- 5/6
4 x 5/6 = 20/6
20/6 = 3,33...

Step-by-step explanation:
Isolating a variable means rearranging an algebraic equation so that a different variable is on its own.
Answer:
180
Step-by-step explanation:
From the table :
Slope :
m = (y2 - y1) / (x2 - x1)
m = (100 - 80) / (5 - 4)
m = 20 / 1
m = 20
y = 20x
Hence, when, x = 12
y = 20 * 12
y = 240
From the graph:
Slope :
m = (y2 - y1) / (x2 - x1)
m = (280 - 70) / (8 - 2)
m = 210 / 6
m = 35
y = 35x
When x = 12
Graph :
y = 35 * 12
y = 420
Difference :
420 - 240
= 180
