Answer:
My answer came out to -22.
Step-by-step explanation:
Start multiplying from left to right:
Two negatives multiplied are positive:
-2.2·(-2)=4.4
A negative and a positive multiplied equal a negative:
4.4·(-1)=-4.4
-4.4·5=-22
 
        
             
        
        
        
Ratio 5:2 as fraction should be 5/2
as you know 5/2 = 2.5
This is the biggest compared to 9/5, 8/5 and 2/7
9/5 < 2
8/5 <2
2/7 < 1
so 5/2 is greatest

Answer:
A
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (6, a ) and (x₂, y₂ ) = (9, - 4 )
m =  =
 = 
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
2x - 3y = 6 ( subtract 2x from both sides )
- 3y = - 2x + 6 ( divide through by - 3 )
y =  x - 2 ← in slope- intercept form
 x - 2 ← in slope- intercept form
with slope m = 
Parallel lines have equal slopes , then
 =
 =  , so
 , so
- 4 - a = 2 ( add 4 to both sides )
-a = 6 ( multiply both sides by - 1 )
a = - 6 → A
