PLEASE HELP 25 POINTS Write the equation for the following relation. Include all of your work in your final answer. Submit your

Deffense [45]

R = {(x, y): (4, 5), (8, 7), (12, 9), (16, 11), . . .}

Notice that y increases by 2 when x increases by 4

slope = 2/4 = 1/2

Notice that if you decrease x by 4 y will decrease by 2

So, y-intercept = (0,3)

Equation: y = (1/2)x+3

---------------------

R = {(x, y): (2, 3), (4, 4), (6, 5), (8, 6), . . .}

slope = 1/2

y-int: (0,1)

Equation: y = (1/2)x + 1

---------------------

Q = {(x, y): (2, 8), (3, 27), (4, 64), (5, 125), . . .}

Not a linear relation because y does not increase consistently

as x increases.

Equation: y = x^3

------------------------------

P = {(x, y): (1, 0), (2, 4), (3, 8), (4, 12), . . .}

slope = 4

y-int: -4

Equation: y = 4x-4

Can someone help me on this math problem.

nekit [7.7K]

In the rhombus, the diagonals are perpendicular.

We know, the sum of the measures of the triangle is equal 180°.

Therefore we have the equation:

$(2x-15)+3x+90=180$

$2x-15+3x+90=180$ <em>combine like terms</em>

$(2x+3x)+(-15+90)=180$

$5x+75=180$ <em>subtract 75 from both sides</em>

$5x=105$ <em>divide both sides by 5</em>

$\boxed{x=21}$

<h3>Answer: x = 21°</h3>

What is the Domain and Range *DON'T FORGET PARENTHESES AND BRACKETS*

Anastasy [175]

Answer:

Domain: (-5,-4,-3,-2,-1,0,1,2,3,4,5)

Range: (0,1,2,3,4, -1, -2)

Step-by-step explanation:

Domain means all of the x-axis values on the graph, so for example in (-2,0), -2 would be part of the domain and 0 part of the range. Therefor, what you would do would be take all of the plots and put all x values as the domain and all y values as the range. Hope this helped!
