greatest to least: 6.32, 6, 4.27, 4, 3.5 .
I got 4.27 by multiplying 4 x 11, adding three which makes it 47 and then divided it by 11
Answer:
Associative Property of Addition
Step-by-step explanation:
When you add, you can group the numbers in any combination.
Answer:
-1
Step-by-step explanation 4 - 3x= 2x+9
take x in a side and the numbers in the other side then 4-9=2x+3x................-5=5x.....x=-1
To solve this problem, you must name a variable, create expressions representing the parts of the problem, and then set up an equation.
Let Tim's age today be t. Since Tim's mom's age five years ago was 3 times Tim's current age, Tim's mom's current age is equal to 3t + 5.
Their ages are collectively 45, so Tim's age t and Tim's mom's age 3t + 5 must be equal to 45. Set up an equation and solve for the variable t.
45 = t + (3t + 5)
45 = t + 3t + 5
45 = 4t + 5
40 = 4t
10 = t
Tim is currently 10, and after plugging 10 for t into 3t + 5, we see that Tim's mom is 35.
Now let's check our work. Their combined ages are 45; 10 plus 35 is equal to 45, so that is correct. Further, addressing the "Five years ago, Tim's mom was three times Tim's age today" bit, we see that 10 - Tim's current age - times 3 is equal to 30, which would be Tim's mom's age 5 years ago.
Answer:
Today, Tim's mom is 35.
Answer:
(a)

(b)

(c)

Step-by-step explanation:
(a)
Simply evaluate (a+h) in the function:

(b)
Evaluate (a) in the function:

Using the previous answers lets calculate f(a+h)-f(a)

(c) To find the rate of change of f(a+1) when a=7 we need to calculate its derivate at that point:
