REC(x) = 1

Mathematics
1 answer:
Nastasia [14]4 years ago
4 0

Answer: a. 8; 1/2

Step-by-step explanation:

a. if the function is f(x)=2x+3 and they ask you what is f(5)? Then you just replace x with what they replaced x with and solve. f(5)=2(5)+3. 2x5=10+3=13 so then f(5)=13. So in your case they replace x with 2. Plug it in. h(2)=2^2+4.

2 to the power of 2 is 4 and then + another 4 which is 8. Thats how you get the first one, now you try and solve REC(2).

igomit [66]

Answer:

165 liters of 15% solution

Step-by-step explanation:

15F + 65S = 60(1650)

F + S = 1650

F = 1650-S

15(1650-S) +65S = 99000

50S = 99000-24750= 74250

S = 74250/50 = 7425/5 = 1485 liters of 65% solution

F = 1650-1485 = 165 liters of 15% solution

65 is much closer to 60 than 15 is,  so you know there will be mostly 65% solution with relatively little 15%

Hope this helps, have a nice day/night! :D

What is the answer for 1/4 ( 12x + 24 ) -9x
Gekata [30.6K]

The final expression is -6x+6

Step-by-step explanation:

The expression that we have is

\frac{1}{4}(12x+24)-9x

In order to solve the expression, we start by applying the  distributive property to the bracket. We get:

\frac{1}{4}\cdot 12x + \frac{1}{4}24 -9x

Simplifying,

3x+6-9x

Now we add the two terms in x, and we find:

(3x-9x)+6=\\-6x+6

Which is the final expression.

A retail shop is replacing their flooring with laminate wood. The floor plan is shown below. Determine the total square feet of
Phantasy [73]
<h3>Answer:  1075 square feet</h3>

===========================================================

Explanation:

As shown in the diagram below, I've drawn a blue horizontal line to split the figure into two rectangles (smaller one up top, larger down below).

The smaller rectangle up top is 25 ft by 8 ft, giving an area of 25*8 = 200 sq ft.

The larger rectangle down below is 35 ft by 25 ft so we have an area of 35*25 = 875 sq ft.

The total area is 200+875 = 1075 square feet

Notes:

  • We can write "square feet" as "sq ft" or as "ft^2" without quotes.
  • The portion "5 ft", in the upper left corner, is never used.
