Answer:
Step-by-step explanation:
To factor by grouping, take the first two numbers and last two numbers. First, look at the first two numbers.
Each number can be divided by 7 and x^2, so pull it out as a GCF.
Next, look at the last two numbers.
Each number can be divided by 3, so we will pull it out as a GCF.
Add the two results together.
When factoring by grouping, the two expressions in the parenthesis should always be the same. In this case, it is x-3.
Combine the numbers outside and inside parenthesis.
Answer:
The amount to be pay for coat is <u>$128.70</u>.
Step-by-step explanation:
Given:
The sales tax rate is 7.25% in California.
The cost for a coat in Los angeles is $120.00.
Now, to find amount to be paid.
Sales tax = 7.25%.
Cost = $120.00.
So, amount to be paid = $120 + 7.25% of $120.00.
Therefore, the amount to be pay for coat is $128.70.
Step-by-step explanation:
The interval of increasing for both the given functions f((x) and g(x) is given by : (-∞, 4)
Step-by-step explanation:
The function f(x) = |3x| + 3
Since, The modulus function is always increasing so adding 3 to it also increase over the whole number line.
So, The interval of increasing for the function f(x) : (-∞, +∞)
The function g(x) = -x² + 8x - 5
⇒ g'(x) = -2x + 8
To find critical points : g'(x) = 0
⇒ -2x + 8 = 0
⇒ x = 4
So, Intervals of increasing or decreasing are : (-∞, 4) and (4, +∞)
Now, On checking g(x) is increasing on (-∞, 4) and decreasing on (4, +∞)
Hence, The interval of increasing for both the given functions f((x) and g(x) is given by : (-∞, 4)
