For -4+2, plot -4, then move to the right 2 spaces. You should land on -2.
For -4+(-2), plot -4 then move the left 2 spaces. You should land on -6.
Answer:
14
Step-by-step explanation:
6 x 10 = 60
60 - 5 = 55
5 x 10 = 50
50 - 9 = 41
55 - 41 = 14
One vertex the rectangle lies on the straight line x + y = 6, which means that the sum of lengths of two adjacent sides is 6. Then the perimeter is 12 cm.
Begin by multiplying both sides by 2 to get rid of the fraction. The standard form for a line is Ax + By = C, no fractions allowed. By multiplying we get 2y=-1x+3. Now move the -1x over by adding and we have the standard form we are looking for: x + 2y = 3.
