-2(5x-1) + 7(5x-1) - 3(-5x+1)
LuckyWell [14K]
First you would distribute through the parenthesis
-10x+2+7(5x-1)-3(-5x+1)
Then distribute
-10x+2+35x-7-3(-5x+1)
And then distribute 3
-10x+2+35x-7+15x-3
Collect like terms
40x+2-7-3
40x-8 is your answer :)

Alika [10]

Functions can be represented using equations and graphs Both f(x) and g(x) include domain values of [4, ∞) and range values of [0, ∞), and both functions have a y-intercept in common.

<h3>How to determine the key features?</h3>

The domain of the function is defined as the set of the numbers we are allowed to put in the function while the range is the assumed data put in the function.

The functions are given as:

F(x)=e^{-x}\\\\\\g(x)=-\sqrt{x-4}

Using a graphing calculator:

The domain of g(x) is [4, ∞)

The range of g(x) is  [0, ∞)

The domain of f(x) is  (–∞, ∞),

The range of f(x) is  [0, ∞)

Both functions have positive values for their domains

By comparing the above highlights, the true statement between functions g(x) and f(x) is option 3

Simplify the following expressions by combining like terms. Then, tell if the expressions are equivalent.
dezoksy [38]

Answer:

<em>2+4r. Expressions are equivalent.</em>

Step-by-step explanation:

  • <em>3r + 10 + r -8 </em>

<em> Multiply r and 3 </em>

<em>Multiply r and 1 </em>

<em> The r just gets copied along. </em>

<em> The answer is r </em>

<em> r </em>

<em> 3*r evaluates to 3r </em>

<em> 3*r+10 evaluates to 3r+10 </em>

<em> 3r + r = 4r </em>

<em> The answer is 4r+10 </em>

<em> 3*r+10+r evaluates to 4r+10 </em>

<em> 10 - 8 = 2 </em>

<em> The answer is 2+4r </em>

<em> 3*r+10+r-8 evaluates to 2+4r </em>

<em> The final answer is </em>

<em>2+4r</em>

<em />

  • <em>8 + 2(2r) - 6 </em>

<em> Multiply r and 2 </em>

<em>Multiply r and 1 </em>

<em> The r just gets copied along. </em>

<em> The answer is r </em>

<em> r </em>

<em> 2*r evaluates to 2r </em>

<em> Multiply 2 and 2r </em>

<em> Multiply 1 and r </em>

<em> The r just gets copied along. </em>

<em> r </em>

<em> 2*(2*r) evaluates to 4r </em>

<em> 8+2*(2*r) evaluates to 8+4r </em>

<em> 8 - 6 = 2 </em>

<em> The answer is 2+4r </em>

<em> 8+2*(2*r)-6 evaluates to 2+4r </em>

<em> The final answer is </em>

<em>2+4r</em>
