Answer:

well, r = 79°

s = 63°

Step-by-step explanation:

r = 90° - 11° = 79°

s = 90° - 27° = 63°

<h2>answer.</h2>

y is ⅓ of x

<h3>step by step explanation.</h3>

ratio of x to y is 3:1

x=¾

y=¼

¼÷¾=⅓

that means y is ⅓ of x

to confirm the answer.when you take¾×⅓=¼.

Graph y < x2 + 4x. Click on the graph until the correct graph appears.

Answer: The correct answer is:

_________________________

The given "graph" in the bottom right, lowest corner

Step-by-step explanation:

_________________________

Note: When there is only one (1) equation give for a graph;

and/or: only one (1) "inequality given";

we look for the symbol.

If the symbol is "not" an "equals" symbol (i.e. not an: = symbol) ;

we check for the type of "inequality" symbol.

If there is a: "less than" (<) ; or a "greater than" (>) symbol; the graph of the "inequality" will have "dashed lines" (since there will be a "boundary").

If there is an "inequality" that is a: "less than or equal to" (≤) ;

or a: "greater than or equal to" (≥) ;

→ then there will be not be a dashed line when graphed;

but rather—a "solid line" ; since "less than or equal to" ;

or "greater than or equal to" —is similar to:

"up to AND including"; or: "lesser/fewer than AND including".).

_________________________

Note: We are given the "inequality" :

→ " y < x² + 4x " .

_________________________________

Note that we have a "less than" symbol (< ) ; so the graph will have a:

"solid line" [and not a "dotted line".].

_________________________________

Note that all of the graphs among our 4 answer choices have "dotted lines".

Not that all values (all x and y coordinated) within the "shaded portion" of the corresponding graph are considered part of the graph.

As such, given any point within the shaded part, the x and y coordinates must match the inequality (i.e. the given inequality must be true when one puts in the "x-coordinate" and "y-coordinate" into the "given inequality" :

→ " y < x² + 4x " .

_________________________

Likewise, we can take any point within the "white, unshaded" portion of any of the graph, and take the "x-coordinate" and "y-coordinate" of that point, and the inequality: → " y < x² + 4x " ; will not hold true when the "x-coordinate" and "y-coordinate" values of that point— are substituted into the "inequality".
