What is (f - g)(x)?

(4,3) and (8,6)<br><br> Slope:

nikdorinn [45]

The slope would be 3/2. The formula is (y2-y1)/(x2-x1) which is (6-3)/(8-4)= 3/2

Answer:

The error is located in step 9, because the student made the following operation: $(-4)\cdot (-r) = -4\cdot r$ , instead of $(-4)\cdot (-r) = 4\cdot r$ , presented in step 4) of our demonstration. The real solution is 9.

Step-by-step explanation:

First, we proceed to show the appropriate process to solve the equation for $r$ by algebraic means. That is:

1) $-4\cdot (6-r) = 12$ Given

2) $(-4)\cdot [6+(-r)] = 12$ Definition of substraction

3) $(-4)\cdot (6) +(-4)\cdot (-r) = 12$ Distributive property

4) $(-24) +4\cdot r = 12$ $(-a)\cdot b = -a\cdot b$ / $(-a)\cdot (-b) = a\cdot b$

5) $4\cdot r +[24+(-24)] = 12 +24$ Compatibility with addition/Commutative and associative properties

6) $4\cdot r = 36$ Existence of additive inverse/Modulative property

7) $r\cdot (4\cdot 4^{-1}) = 36\cdot 4^{-1}$ Compatibility with multiplication/Commutative and associative properties

8) $r = 9$ Existence of multiplicative inverse/Definition of division/Result

The error is located in step 9, because the student made the following operation: $(-4)\cdot (-r) = -4\cdot r$ , instead of $(-4)\cdot (-r) = 4\cdot r$ , presented in step 4) of our demonstration. The real solution is 9.

Answer:

See graph attached.

The path of the curve, as t increases goes from the top of the curve going down, following a parabola symmetric in y=5.
