Answer:

a) f(4) = 2(4) - 5 = 3

Step-by-step explanation:

First, we look at the function, and we see different domain restrictions.

We are given the value of 4. The first equation has a domain restriction which includes 4 as it has the line below the greater than sign.

So, the first equation must work.

So our answer is A.

The answer would be 12 feet square.

That’s because taking out the square is taking out an area of 4 feet square. If you substitute the 4 feet square back in, that would fill in the empty spot marked with the 2 feet by 2 feet dimensions. Then, you could treat it like a rectangle of 4 by 3. If you multiply them you’ll get 12 feet square which is your answer. Hope this helps

Answer:

y=32, x=96

Step-by-step explanation:

The complete question in the attached figure

we know that

r=\frac{4x+8y}{x+y} ----> given problem

r=5\% ----> given problem

substitute the value of r in the expression

5=\frac{4x+8y}{x+y}

Simplify the expression

Multiply both sides by (x+y)

5(x+y)=4x+8y\\5x+5y=4x+8y\\5x-4x=8y-5y\\x=3y

So

In the table, just look for two values, one of which is three times the other

<u><em>Verify each number in the table</em></u>

1) For y=21 ----> x=3(21)=63

The value of 63 is not in the table

2) For y=32 ----> x=3(32)=96

The value of 96 is in the table

3) For y=51 ----> x=3(51)=153

The value of 153 is not in the table

4) For y=64 ----> x=3(64)=192

The value of 192 is not in the table

5) For y=81 ----> x=3(81)=243

The value of 243 is not in the table

6) For y=96 ----> x=3(96)=288

The value of 288 is not in the table

therefore

y=32, x=96
