Answer:
Yes! You would sub 10-3x for y and solve.
Don't forget to use the distributive property! Your answer should be 5.

Answer:
2. chord theorem; t = 10.5
3. chord theorem; x = 5
Step-by-step explanation:
For both of these problems, the relevant theorem is the "intersecting chord theorem", also referred to as the "chord theorem." It tells you the product of the lengths of the parts of one chord is equal to the product of the lengths of the parts of the other chord.
2. 20t = 10·21
t = 210/20 . . . . divide by 20
t = 10.5 . . . . . . . simplify
__
3. 10(x +4) = 15(x +1)
10x +40 = 15x +15 . . . . . eliminate parentheses
25 = 5x . . . . . . . . . . . . . subtract 10x+15
5 = x . . . . . . . divide by 5
For this case we must resolve each of the inequalities and find the solution set.
Inequality 1:

We subtract 7 from both sides of the inequality:

We divide between 12 on both sides of the inequality:

Thus, the solution is given by all values of x less than
Inequality 2:

We add 8 to both sides of the inequality:

We divide between 5 on both sides of the inequality:

Thus, the solution is given by all values of x greater than
The solution set is given by:
