Determine the constant of proportionality for the graph.

PLEASE HELP ME!!!!

Answers

Answer 1

Answer:

Answer:

$(1)/(5)$

Step-by-step explanation:

On your recent question- you stated that when the x value was 10, the y value was 2. The graph started at the origin. To find the constant of proportionality, use the equation $(rise)/(run)$ . In this case, the "run" was 10, since it went +10 from 0. The "rise" was 2, since it went +2 from 0.

$(2)/(10) = (1)/(5)$ simplified.

Answers

Answer:

x+y=1500

10.50x+7.50y=13950

multiply the first one by -7.5 to eliminate y

-7.5x-7.5y=-11250

Which function below is the inverse of f(x) = x2 − 9?

Answers

Let f(x)=y
y= $x^(2) -9$
Make x the subject of the formula;
y+9= $x^(2)$
x= $√(y+9)$
So, the inverse of the function is thus;
$f^(') = √(x+9)$

f (x)=y
y=2x-9

X Y
-2 -15 y=2 (-2)-9
y=-4+-9
y=-15

-1 -11 y=2 (-1)-9
y=-2+-9
y=-11

0 -9 y=2 (0)-9
y=0+-9
y=-9

1 -7 y=2 (1)-9
y=2+-9
y=-1

2 -5 y=2 (2)-9
y=4+-9
y=-5

What is the probability of not drawing a green marble from a jar containing 7 red, 4 green, 3 white, and 9 blue marbles?

Answers

$7+4+3+9$
$11+12$
$23$

$(23)/(23) - (4)/(23)$

$(23-4)/(23)$

$(19)/(23)$ $chance$

Answer:

Probability of not drawing a green marble is 19/23.

Step-by-step explanation:

A jar is containing 7 red, 3 white, and 9 blue marbles.

Then the probability to draw a green marble will be = Numbers of green marbles/ Total numbers of marbles of all colors

P(G) = 4/(7 + 4 + 3 + 9)

P(G) = 4/23

Now the probability of not drawing a green marble = 1 - probability of drawing a green ball

P = 1 - 4/23 = 19/23

Therefore answer is 19/23.

What are the domain and range of the function {(5, 3), (7, 1), (11, –2), (4, 9), (–2, 4)}? A.

Domain: {3, 1, 9, 4}; Range: {5, 7, 11, 4, }

B.
Domain: {5, 7, 11, 4, }; Range: {3, 1, 9, 4}

C.
Domain: {5, 7, 11, 4, –2}; Range: {3, 1, –2, 9, 4}

D.

Domain: {3, 1, –2, 9, 4}; Range: {5, 7, 11, 4, –2}

Answers

Answer is C. Set of first part of the binary set is domain and second part of it is range. So the domain will be {5, 7, 11, 4, –2} and the range will be {3, 1, –2, 9, 4}

Answer:

Domain: {5, 7, 11, 4, –2}; Range: {3, 1, –2, 9, 4}

Step-by-step explanation:

The domain is the X value or the independent in put.

Range is the Y values, or the Dependant input.
