1 Remove parentheses.

2(5c−7)≥c−3

2 Expand.
10c−14 ≥ c −3

3 Add 14 to both sides.
10c-14+14≥ c − 3+14

4 Simplify c−3+14 to c+11
10c≥c+11

5 Subtract c from both sides.

10c−c≥11

6 Simplify 10c−c to 9c
9c≥11

7 Divide both sides by 9.
c ≥11/9

Maria is comparing the prices of two window cleaning companies. Company A charges $6 per window and an additional $12 as service

Pani-rosa [81]

Part A: 6w + 12 = 5w + 15

Part B: 6(8) + 12 = 5(8) + 15
48 + 12 = 40 + 15
60 = 55 = Company B equals $55 which is less than $60

Part C: $5 is saved because of the amount of money.
Hope this helps :)

Given that the function g is defined by the rule g(x)=3-2x,determine the following

Illusion [34]

Answer:

The value of g(a) is:

g(a) = 3 - 2a

Step-by-step explanation:

Given

As the function g(x) is given by

$g(x)=3-2x$

To determine

g(a) = ?

In order to determine g(a),

substitute x = a in the function g(x) = 3 - 2x

g(x) = 3 - 2x

g(a) = 3 - 2(a)

g(a) = 3 - 2a

Therefore, the value of g(a) is:

g(a) = 3 - 2a
