Answer:
980 students
Step-by-step explanation:
14/20=x/1400
cross multiplication and then u get the equatiton 20x=19600
solve and get 980
Given data:
The graph of the given points is shown below.
The slope of the line passing through A(-2, -3) and B(-6, -6).
The slope of the line passing through B(-6, -6) and C(-8, 5).
The slope of the line passing through A(-2, -3) and C(-8, 5).
The product of the slope of line passing through AB and line passing through AC is,
Thus, the line passing through AB and line passing through AC are perpendicular.
No the product will be less than 9/10.
This can be easily seen if the fractions are converted into decimals.
The decimal form of the product of 7/8 and 9/10 is 0.867 while the decimal form of 9/10 is 0.9. Therefore, the product of 7/8 and 9/10 is not greater than 9/10
Answer:
4(a + b)^2
p = 6/5 or 1.2
Step-by-step explanation:
Question One
z = a^2 + b^2
y = ab
4z = 4*a^2 + 4*b^2
8y = 8*ab
=================
4z + 8y = 4a^2 + 8ab + 4b^2
4z + 8y = 4(a^2 + 2ab + b^2)
4z + 8y = 4(a + b)^2
Question Two
2(p + 1) + 8(p - 1) = 5p
2p + 2 + 8p - 8 = 5p
2p + 8p + 2 - 8 = 5p
10*p - 6 = 5p
10*p = 5p + 6
10p - 5p = 6
5p = 6
p = 6/5 or 1.2
