Answer:
The answer is [10+(9x3]+4 and 5x4+(7x3).
Step-by-step explanation:
I can't really explain, but if you add 10+4, it'll be 14.
If you multiply 9x3, it'll be 27.
So, if you add 27+14, it will be 41.
For the second answer:
If you also multiply 7x3, it'll be 21. If you ALSO multiply 5x4, its 20. So if you add 20+21, it will equal 41.
Answer:
y = 8
Step-by-step explanation:
Line1 with points (4, 1) and (0, 0):
slope = (y₂ - y₁) / (x₂ - x₁)
= (0 - 1) / (0 - 4)
= 1/4
Perpendicular line is opposite inverse so original slope 1/4 becomes -4/1 or simply -4.
Line2 with points (1, 0) and (-1, y):
slope = (y₂ - y₁) / (x₂ - x₁)
= (y - 0) / (-1 - 1)
= y / -2
y must equal to 8 for the slope to be -4 as stated above.
50 mm = 5 cm
130 + 5 = 135 cm
130 cm = 1300 mm
1300 + 50 = 1350 mm
