solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation. You'll probably start out by just solving proportions, like this:

<span><span><span>Find the unknown value in the proportion:  </span><span>2 : x = 3 : 9.</span></span><span>2<span> :</span> x = 3<span> :</span> 9</span>First, I convert the colon-based odds-notation ratios to fractional form:.Then I solve the proportion:<span> 
</span><span>9(2) = </span><span>x(3)</span> <span>
1</span><span>8 = 3x</span><span> 
</span><span>6 = x</span></span><span><span><span>Find the unknown value in the proportion:  </span><span>(2x + 1) : 2 = (x + 2) : 5</span></span><span>(2x + 1)<span> :</span> 2 = (x + 2)<span> :</span> 5</span><span><span> ADVERTISEMENT</span><span> </span></span>First, I convert the colon-based odds-notation ratios to fractional form:Then I solve the proportion:<span> 
</span><span>5(2x + 1)  =  2(x + 2)</span><span> 
</span><span>10x + 5  =  2x + 4</span><span> 
</span><span>8x  =  –1</span><span> 
</span><span>x = –1/<span>8</span></span></span>

Use graphing technology to find the range of the function f(x)=2^x+1.f(x)=2 <br> x<br> +1
marusya05 [52]

The range of the given function is equal to (2, 7).

<h3>What is a range?</h3>

A range can be defined as the set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range refers to the set of all possible output numerical values, which are shown on the y-axis of a graph.

<h3>How to identify the range and domain of this graph?</h3>

The vertical extent of a graph represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.

Similarly, the horizontal extent of a graph represents all domain values and they are also read and written from smaller to larger numerical values, and from the left of the graph to the right.

By critically observing the graph of function f(x) shown, we can infer and logically deduce the following:

Range = (2, ∞).

Need help asap!!!! will give brainliest!
Airida [17]

Answer:

Y = 3 \sqrt{2}/2 And x = 3

Step-by-step explanation:

Because this is a 45 to 45 degree triangle, the 3 * (square root of 2 )/2 is y as well. Because this is a 45-45 triangle, x should be y (Square root of 2). Therefore, replacing y with 3 * (square root of 2 )/2 and multiply the square root of 2, the answer for x is 3. If I got something wrong please tell me, thanks.
