<span>Answer: option B. each input value is mapped to a single output value.
</span><span />

<span>Justification:
</span><span />

<span>A function (per definition) is an unambiguos rule that maps each input to a different output.
</span><span />

<span>That means that a single input value cannot have two (or more) different images (output values of the function).
</span><span />

<span>Then, the graph of a function cannot have two different points with the same x-coordinate.
</span><span>
</span><span>
</span><span>For example, these two points (0,5) and (0,6) cannot belong to a same function, because that is relating the same input (0) to two different values (5 and 6) which is precluded by the definition of function.</span>

Kevin has a rectangular

Nikitich [7]

Answer:

20 feet long

Step-by-step explanation:

To solve this you need to use the Pythagorean theorum, $a^2+b^2=c^2$ , where c is the length of rope needed and A and B are the side lengths. Think of it like a right triangle.

So, the equation is

$12^2+16^2=c^2$

Which is then

$144+256=c^2$

$c^2=400$

And the possible values of c are 20 and -20.

From here we know the answer cannot be -20 because you cannot have a negatively long length of rope, so the answer must be 20 feet.

what is the equation of the line that is perpendicular to the line y=-3x+2 and passes through (3,-1)

Ivenika [448]

Answer:Answer: y=x/3−2.

Step-by-step explanation:

find the equation of the line perpendicular to the line y=2−3x passing through the point (3,−1).

The equation of the line in the slope-intercept form is y=2−3x.

The slope of the perpendicular line is negative inverse: m=13.

So, the equation of the perpendicular line is y=x3+a.

To find a, we use the fact that the line should pass through the given point: −1=(13)⋅(3)+a.

Thus, a=−2.

Therefore, the equation of the line is y=x3−2.

Answer: y=x/3−2.

You practice playing your guitar every day. You spend 15 minutes practicing chords and the rest of the time practicing a new son

Black_prince [1.1K]

Answer:

<h2>x=(y-105)/7</h2>

Step-by-step explanation:

Given that the total time taken to practice is given by the expression as

y=7(15+x)

Simplifying the expression we have

y=105+7x

Solving for x (that is making x subject of formula we have)

7x=y-105

Divide both sides by 7 we have

x=(y-105)/7

Therefore the expression is

x=(y-105)/7

Compare adding unlike fractions and adding like fractions

muminat

Answer:

We just add numerators and rewrite denominator.

Adding unlike dominators:

We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.

Step-by-step explanation:

You mean unlike denominators and like denominators.

Adding like dominators: We just add numerators and rewrite denominator :

Example : $\frac{1}{4} +\frac{2}{4}=\frac{1+2}{4} =\frac{3}{4}$

Adding unlike dominators:

We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.

For example :

$\frac{1}{5}+\frac{3}{4}$

LCM for 5 and 4 is 20 : Now, divide by 5 and multiply by 1 for first fraction. 20 divide by 4 and multiply by 3 :

$\frac{1*4}{20} +\frac{3*5}{20}=\frac{4}{20} +\frac{15}{20}=\frac{19}{20}$
