Answer:
Option A - 
Step-by-step explanation:
Given : Expression 
To find : Solve the expression ?
Solution :
Step 1 - Write the expression
Step 2 - Multiply the first two bracket in multiplication if base are same power get added and apply symbol rule of multiplication 
Step 3 - Again multiply the bracket,
Therefore, Option A is correct
First expression: (-7)/(-4)
Divide. Note that two negative numbers divided will result in a positive answer
(-7)/(-4) = 7/4 = 1.75
First expression: Greater than 1.
-----------------------------------------------------------------------------------------------------------------
Second expression: -(3/2)
Simplify: 3/2 = 1.5
-(1.5) = -1.5
Second expression: Less than -1
--------------------------------------------------------------------------------------------------------------
Third expression: (-8/5) x (-5/8)
Note that two negatives = one positive answer when multiplying
8/5 x 5/8 = 40/40 = 1
Third expression: Neither
----------------------------------------------------------------------------------------------------------------
Fourth Expression: (-5)/(-3)
Divide: (-5)/(-3) = 5/3 = ~1.67
Fourth Expression: Greater than 1
----------------------------------------------------------------------------------------------------------------
Fifth Expression: (-9)/6
Divide: (-9)/6 = -1.5
Fifth expression: Less than -1
----------------------------------------------------------------------------------------------------------------
hope this helps
Slope = -1
x-intercept = 3/-1 = -3.00000
f-intercept = 3/-1 = -3.00000
Slope = 0.667/2.000 = 0.333
x-intercept = 3/-1 = -3.00000
f-intercept = 3/3 = 1
Slope = 0.400/2.000 = 0.200
x-intercept = 3/-1 = -3.00000
f-intercept = 3/5 = 0.60000
Slope = 0.286/2.000 = 0.143
x-intercept = 3/-1 = -3.00000
f-intercept = 3/7 = 0.42857
What do you mean what is UW ? There is no equation
Answer:
y= ab if a≠b
Step-by-step explanation:
y/a −b= y/b −a
multiply each side by ab to clear the fractions
ab(y/a −b) = ab( y/b −a)
distribute
ab * y/a - ab*b = ab * y/b - ab *a
b*y - ab^2 = ay -a^2 b
subtract ay on each side
by -ay -ab^2 = ay-ay -a^2b
by -ay -ab^2 =-a^2b
add ab^2 to each side
by-ay -ab^2 +ab^2 = ab^2 - a^2b
by-ay = ab^2 - a^2b
factor out the y on the left, factor out an ab on the right
y (b-a) = ab(b-a)
divide by (b-a)
y (b-a) /(b-a)= ab(b-a)/(b-a) b-a ≠0 or b≠a
y = ab
