Answer:
x = 2/3 or 0.666...
Step-by-step explanation:
-3 + 1 + 10x = x + 4
-2 + 10x = x + 4
10x = x + 4 + 2
10x = x + 6
10x - x = 6
9x = 6
x = 6/9
x = 2/3 or 0.666...
Answer:
4.95+0.10x=120
Step-by-step explanation:
Hope this helps
You could substitute with 6 for x+9 and 9 for x+6 , otherwise it be 0=-3 or no solution
This is a parabola which has vertex at the origin and opens upwards.
general form is x^2 = 4ay where a is the focus
the focus is the same distance from the vertex as the directrix So it is at the point (0, 6)
required equation is x^2 = 4*6 y
or y = (1/24) x^2
Answer:
a. The variable X represents the amount of hot dogs
b. the variable Y represents the amount of sodas
c. Their total expense would be $13.50
If you multiply $1.50 by 7 you would get $10.50, then you would multiply $0.75 by 4 and get $3.00.
then you would add 10.50 and 3.00 to get $13.50
