Answer:
you just have to check the first and the third box
Step-by-step explanation:
put each into slop intercept form
y+6=-5(x-2) is the same as y=-5x+4
y-2=-5(x+6) is the same as y=-5x-28
y=-5x+4
y=-5x-28
all of them have a slope of -5, but you need to plug in (2,-6) to see which on is true
Answer:
The container's base is 2 by 2 meters
If it contains 400 liters, its height must be 100 cm
2 x 2 x .10 meters = .4 cubic meters = 400 liters
Step-by-step explanation:
Answer:
line a and b are parallel, there is no perpendicular lines
Step-by-step explanation:
Looking at the slope of each line, you can identify whether the lines are parallel, perpendicularlar, or neither.
When the slopes are the same, they are parallel.
When the slopes have opposite sign and numerator and denominator flipped, they are perpendicular. Ex.
and
are perpendicular slopes.
Finding slope is using the formula: 
Line a has slope
= 
Line b also has slope 
Line c has slope 2
Since slope of line a and b are same, they are parallel.
Line c is not perpendicular to line a and b because the slope should have opposite sign and numerator and denominator flipped, which is 4 not 2.
Answer:
a. (6x-5)^2
b. 4x(2x^2+1)
c. -4(x-12)(x+3)
d. (2x+1)(4x-3)
Step-by-step explanation:
Andy because 4 and 4 are the same numbers. If one of the numbers was 4.1 that would have been uneven.
