The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms.
hope it helps!!!! :]
Answer: 281.7
Step-by-step explanation:
Line YZ is the midsegment of triangle QRS because it connects the midpoints of lines QR and RS. We would solve for x by appying the midsegment theorem which states that the midsegment is half the length of the third side or base. This means that
YZ = 1/2(QS)
x + 2 = 1/2 * (3x - 8)
2(x + 2) = 3x - 8
By opening the parenthesis, we have
2x + 4 = 3x - 8
Collecting like terms, we have
3x - 2x = 4 + 8
x = 12
Option C is correct
Answer:
x = 2
Step-by-step explanation:
Solve for x:
5 x - 5 = 3 x - 9
Subtract 3 x from both sides:
(5 x - 3 x) - 5 = (3 x - 3 x) - 9
5 x - 3 x = 2 x:
2 x - 5 = (3 x - 3 x) - 9
3 x - 3 x = 0:
2 x - 5 = -9
Add 5 to both sides:
2 x + (5 - 5) = 5 - 9
5 - 5 = 0:
2 x = 5 - 9
5 - 9 = -4:
2 x = -4
Divide both sides of 2 x = -4 by 2:
(2 x)/2 = (-4)/2
2/2 = 1:
x = (-4)/2
The gcd of -4 and 2 is 2, so (-4)/2 = (2 (-2))/(2×1) = 2/2×-2 = -2:
Answer: x = -2
Into the equation y=−3x+b substitute 5 for x and 2 for y, obtaining:
2 = -3(5) + b. Then 2 = -15 + b, or b = 17.
