Answer:
A. {3,4}
Step-by-step explanation:
In order to find the x values which would make the entire function undefined, you would have to factor the bottom equation. Factoring x^2+7x+12 gives you (x+3)(x+4). If you set each of these equal to 0, you end up with the x values being 3 and 4.
The answer will be letter "B" you take 450 times it by 4.29
and u get 1,930.50
Answer:
x>=3
Step-by-step explanation:
5x-6>=9
5x>=9+6
5x>=15
x>=15/5
x>=3
Answer:
x = 9.5
this should be the right answer if the same one you had to solve.
Step-by-step explanation:
y = 2x - 4
y = 12 + 3 combine them
2x - 4 = 12 + 3
+4 +4 The 4's cancel each other out
2x = 12 + 7 Add then divide
2x = 19
2x = 19
---- ----
19 19
x = 9.5

= m Multiply both sides by (x - a)
a - c = m (x - a) Use the Distributive Property
a - c = mx - ma Add ma to both sides
a - c + ma = mx Divide both sides by m

= x Switch the sides to make it easier to read
x = <span>
