Answer:
Area = 4in^2
Step-by-step explanation:
If BAC = 6
3 x 2 = 6
So, EDF's given is 2
2 x 2 = 4
Answer:
The lines are perpendicular
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are equal
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have
----> equation A
isolate the variable y
Divide by 7 both sides

The slope of the line A is 
----> equation B
isolate the variable y
Divide by 3 both sides

The slope of the line B is 
Compare the slope of both lines


so
----> the lines are not parallel
Find the product of the slopes
----> the lines are perpendicular
Now get the square root of 30
Answer:
See below
Step-by-step explanation:
Part 1 -
x: number of hours worked
y: total income
This is written as → y = f(x)
Part 2 -
y = 15*x
Part 3 -
f (35) = 15 × 35 = $525
f (29) 15 × 29 = $435
Week 1 - Ashley worked 35 hours with a total income of $525.
Week 2 - Ashley worked 29 hours with a total income of $435.
A. is not a real number, or square root -3
Negative numbers do NOT have a square root because it is negative
