<span>The limitation of
algebra that leads development of calculus is that it can make a complex number
of variables present it as a single variable and then apply the necessary
formula needed to find the answer. After manipulation, the presented single
variable can be changed back to a complex variable by substitution</span>
Answer:
D
Step-by-step explanation:
For a function in the form f(x) = x, we can say:
- the function f(x) = ax is a vertical stretch if a>1 and compress if 0<a<1
- the function -f(x) is the original, flipped over x-axis
<em>keeping the 2 rules in mind, we can say that</em>
<em>vertical stretch by a factor of 3 would make it f(x) = 3x</em>
<em>Then</em>
<em>flip over x-axis would make it f(x) = -3x</em>

answer choice D is right
Answer:
B. 1
Step-by-step explanation:
5x + 10 = 15
-10 -10
5x = 5
÷ 5 ÷ 5
x = 1
