The answer for the exercise shown above is the second option, the option B, which is: B. In step 3, the addition property of equality was applied incorrectly.
The explanation is:
To solve this problem you must apply the proccedure shown below:. You have the followinwg equation:
<span>
4(m-3)+5(m+2)=m+9
Let's review the steps:
4m-12+5m+10=m+9 (step 1)
9m-2=m+9 (step 2)
8m =7 (step 3) (There is a mistake, because: 9m-m=9+2</span>⇒8m=11)
<span> m=11/8 This should be the step 4</span>
In order to be a function all the x’s must be different. Number 5 is a function. Number 6 is not a function
Answer:
Step-by-step explanation: y=2x−3
Answer:
a. Problem A > Problem B
Step-by-step explanation:
Problem A:
f(x) = x3 + 5
f(-2) = (-2)3 + 5
f(-2) = (-6) + 5
f(-2) = -1
Problem B:
f(x) = x2 - 2
f(-2) = (-2)2 - 2
f(-2) = (-4) - 2
f(-2) = -6
