Answer:
2x-3 < 7 = x ≤ 5 and 5 - x ≤ 8 = x ≥ - 3
Step-by-step explanation:
Answer:
By multiplying the length of one side by the amount of sides there are.
Step-by-step explanation:
If you find one length just find the rest by multiplying.
1. use the equation y -y1 = m(x-x1)
2. (-6,-4) is x1,y1 and (4,-6) is x2,y2
3. y-(-4) = m(x-(-6)
m is the gradient, 10/10, which is 1. make two negatives into a positive.
4. y+4 = x+6
therefore the equation of the lines is y = x+2
substitute the points back into the equation to double check.
Answer:

Step-by-step explanation:
Answer:
$420 dollars without the 20% reduction
Step-by-step explanation:
20% is 1/5 of 100% so you only have 80% which is 336 so you divide 336 by 4 which is 84 so then you add 84 to 336 which equals 420 which is the answer.
