Solve for x :
4 - (2x + 4) = 5
1) x = -10
2) x = 5/2
3) x = 1/2
4) x = 6
<h3><u>Answer</u><u>:</u><u> </u></h3>
➛ 4 - 2x + 4 = 5
➛ 2x + 4 - 4 = 5
➛ 2x + 0 = 5
➛ 2x = 5
➛ x = 5/2
Thus, The value of x is <u>5/2</u><u>.</u><u> </u>
Step-by-step explanation:
-7x + 2y = 18
6x + 6y = 0
21x - 6y = - 54
6x + 6y = 0
27x = -54
x = -2
6(-2) + 6y = 0
-12 + 6y = 0
6y = 12
y = 2
(-2,2)
The dependent variable is f(m)...total money earned per day
the independent variable is m...number of miles
f(m) = 3.5m + 65
for 40 miles..
f(40) = 3.5(40) + 65
= 140 + 65
= 205 <== money earned for the day
========================
the dependent variable is f(p)....total charged
the independent variable is p...the number of pounds
f(p) = 3.5p
for 5 lbs...
f(5) = 3.5(5)
f(5) = 17.50 <== total that was charged
