Given:
y = mx + b
m = slope
b = y-intercept.
m = 1.35
x = 13
25.43 = 1.35(13) + b
25.43 = 17.55 + b
b = 25.43 - 17.55
b = 7.88
y = 1.35(19) + 7.88
y = 25.65 + 7.88
y = 33.53
The monthly cost for 19HCF is $33.53
(2 + 8) / 2 * 9 / 3
Using order of operations, you will solve what is in the parenthesis first.
10 / 2 * 9 / 3
Then you divide.
5 * 3
Then you multiply.
5 * 3 = 15
Hope this helps!
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
