Answer:
The answer is below
Step-by-step explanation:
a)
1/4x + 5/2x - 2 = 4 - 1/4x
collecting like terms:
(1/4)x + (5/2)x + (1/4)x = 4 + 2
3x = 6
x = 6/3
x = 2
b)
7.9x + x + 4 = -1.1x - 16
collecting like terms:
7.9x + x + 1.1x = - 16 - 4
10x = -20
x = -2
c)
3.2x + 5.7 = -2.5x
collecting like terms:
3.2x + 2.5x = 5.7
5.7x = 5.7
x = 1
d)
10.1x - 1.6x + 44 = -7
collecting like terms:
10.1x - 1.6x = -7 - 44
8.5x = -51
x = -6
Hence the equations in increasing order of the value of their solutions is:
10.1x - 1.6x + 44 = -7
7.9x + x + 4 = -1.1x - 16
3.2x + 5.7 = -2.5x
1/4x + 5/2x - 2 = 4 - 1/4x
Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.
The answer is 6.25 square kilometres
one side is 1.25 and the other will be 1.25*4 =5
and for the area we multiply the two 1.25*5=6.25

B. A circle with radius 16 m
Please, Moody, use " ^ " to denote exponentiation:
f(x) = x^3 and g(x) = <span>(x – 1)^3 + 2
Once you have drawn the graph of f(x) = x^3, you get the graph of g(x) by translating the entire graph of f(x) one unit to the right and then translating the result graph 2 units UP.</span>
