Answer:
point D
Step-by-step explanation:
AD is a line and CD is a line
The intersection of two lines is a point ( if the lines intersect)
The two lines intersect at point D
Let the number of apples be x and that of pears be y, then:
0.64x + 0.45y = 5.26 . . . (1)
0.32x + 0.39y = 3.62 . . . (2)
(2) x 2 => 0.64x + 0.78y = 7.24 . . . (3)
(1) - (3) => -0.33y = -1.98
y = -1.98 / -0.33 = 6
From (2), 0.32x + 0.39(6) = 3.62
0.32x = 3.62 - 2.34 = 1.28
x = 1.28 / 0.32 = 4
Therefore, he bought 4 apples and 6 pears.
Answer:
Work done = 0 J
Step-by-step explanation:
work done= ∫ F. dr
= + + + + + + + + + + +
Work done= x²/2 + y²/2 + z²/2
Applying integral limits for entire pathway
Work done= 2 + 0 -2 + 0 + 0+ 25/2 - 25/2 + 0 + 1/2 + 0 - 1/2
Work done = 0 J
absolutely you must choose 3 because only f(x)-1 is able to shift a graph down.
and in question of the left side 1 and 4 and 5 are correct!
I hope you understand it. Also pay attention to if the line is dotted or not because they do matter.
