It's a linear function.

Domain of a linear function is the set of all real numbers.

If the slope of linear function is different than 0, then range is the set of all real numbers.

We have f(s) = 7s + 15. The slope = 7 ≠ 0. Therefore:

Answer: $Domain=\mathbb{R};\ Range=\mathbb{R}$

The sum of two numbers is 36. one number is 3 times as large as the other. what are the numbers

Veseljchak [2.6K]

Answer: 9 and 27
Explanation: x+3x=36
Combine like terms
4x=36
Divide by 4
X=9, which would be one of the numbers.

So if x = 9 we would do 3(9) which would equal 27

So the answer would be 9 and 27

Hope this helps!

bulgar [2K]

Answer:

Part a)

Steve's expression is $2(2x+5)^{2}-7$

For x=3, the expression is equal to $235$

Part b)

Jasmine's expression is

$(3x^{2})+(25x)$

For x=2, the expression is equal to $62$

Step-by-step explanation:

Part a)

Let

n-----> the first term

The expression is

$(n-7)$

$n=2(2x+5)^{2}$

substitute

Steve's expression is

$2(2x+5)^{2}-7$

Evaluate for x=3

$2(2(3)+5)^{2}-7=242-7=235$

Part b)

Let

n-----> the first term

Jasmine's expression is

$(3x^{2})+(25x)$

Evaluate for x=2

$(3(2)^{2})+(25(2))=12+50=62$
