How can I solve a mapping diagram and determine if there a function or not

ch4aika [34]

To check if a relation is a function, given a mapping diagram of the relation, use the following criterion: If each input has only one line connected to it, then the outputs are a function of the inputs.

M angle 3= 31°. Find m angle 4 (complementary angle)

solniwko [45]

Hi, there.

________

$\boxed{\begin{minipage}{8cm} Complementary angles \\ Complementary angles are angles whose sum \\ is 90^\circ. \text{Using this info, let's consider this:} \\ \text{If an angle's measure is 31 degrees, what's} \\ \text{its \ complement?}\end{minipage}}$

$\text{Set up an equation, letting a be the unknown angle}$

$\bold{a+31=90}\\\text{Subtract 31 from both sides}\\\bold{a=59}$

Hope the answer - and explanation - made sense,

happy studying!!

A line crosses through the point (3,10) and another point can be found on the line by going right 2 and down 7. find slope and y

DerKrebs [107]

Answer:

y = $\frac{-7x}{2}+\frac{41}{2}$

Step-by-step explanation:

We are given the point (3, 10).

The second point is 2 on the x-axis and -7 on the y-axis. So our second point is: (3 + 2, 10 - 7) which is (5, 3).

Our formula for slope is m = $\frac{rise}{run}$ = $\frac{y2-y1}{x2-x1}$

So, our equation would be $\frac{3-10}{5-3}$ = $\frac{-7}{2}$

Using the standard formula of a line, y = mx + b, we can substitute for the slope, m.

y = $\frac{-7x}{2}$ + b

Now, we can substitute a point on the line to determine the y-intercept:

Using the point (3, 10),

10 = $\frac{-7(3)}{2}$ + b

b = 10 + $\frac{21}{2}$

b = $\frac{41}{2}$

So our full equation is: y = $\frac{-7x}{2}+\frac{41}{2}$
