All that's necessary is to add 4 to both sides of the equation. This gives
... y = 1/2(x -8) +4
If you like, you can simplify this by eliminating the parentheses and collecting terms.
... y = 1/2·x -4 +4
... y = (1/2)x
Answer:
80°
Step-by-step explanation:
Since a triangle has three angles that add up to 180°, you add the two given angles and subtract it from 180°.
1
70° + 30° = 100°
2
180° - 100° = 80°
Answer:
p= -12/5
Step-by-step explanation:
you have to subtract 2 from both sides
5p+2(-2)=-10 (-2)
5p= -12
5p/5= -12/5
p= -12/5

Step-by-step explanation:
Answer:
w =< 70
(width is less or equal to 70 inches)
Step-by-step explanation:
Let l = length, w = width, h = height
Restrictions given in this question:
'sum of perimeter of the base and the height cannot exceed 130 inches'
perimeter of the base is 2 width and 2 length of the box
perimeter = 2w + 2l
Therefore, inequality involves here is
2w + 2l + h =< 130
(Note that =< here means less or equal)
Then a new condition given with
height, h = 60 in
and length is 2.5 times the width
l = 2.5w
Substitute this new condition into the equation will give us the following:
2w + 2(2.5w) + 60 =< 130
2w + 5w + 60 =< 130
7w + 60 =< 130
7w =< 130-60
7w =< 70
w =< 10
