Answer:

Choice D is the correct one

Step-by-step explanation:

The range of a function simply refers to the possible values the function can assume, that is the set of values that y can take. In the fourth relation, the y-coordinates are 4,5,2

Answer:

d) (3, 4), (5, 5), (5, 2)

Step-by-step explanation:

<em></em>

<em>We are asked to determine which orderpair in the option has the range of {2,4,5}</em>

Using the definition of range:

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

So in the given options if we write the relation in the form of (x,y) then 4, 5, 2 are the values in the range

Answer:x=24

Step-by-step explanation:x/2-8=4

Add 8 to both sides

x/2=12

Multiply each side by 2

Please help<br> Find the area in square units of ABC△ plotted below.
neonofarm [45]

Answer:

Use the distance formula on both points AC and AB.

<em>Distance formula is this</em><em>:</em>

<em>\begin{gathered}d=\sqrt{(x2-x1)^2+(y2-y1)^2} \\\\d=\sqrt{(1--5)^2+(8--7)^2} \\\\d=\sqrt{(6)^2+(15)^2} \\\\d=\sqrt{36+225} \\\\d=\sqrt{261} \\\\\end{gathered}d=(x2−x1)2+(y2−y1)2d=(1−−5)2+(8−−7)2d=(6)2+(15)2d=36+225d=261</em>

Distance for AC  is  16.16

Now do the same with the numbers for AB and get the distance of 5.39

2. To get the area, use the formula 1/2 x base x height

AB is the base and AC is the height.

1/2 x 16.16 x 5.39 = 43.55

the answer is 43.5

The first equation, 8x - 9y = - 23

Obtain the equation in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = ( \frac{1}{2}, 3) and (x₂, y₂ ) = (- 4, - 1 )

m = \frac{-1-3}{-4-1/2} = (- 4)/- \frac{9}{2} = \frac{8}{9}

partial equation is y = \frac{8}{9} x + c

to find c substitute either of the 2 points into the partial equation

using (- 4, - 1 ), then

- 1 = - \frac{32}{9} + c ⇒ c = \frac{23}{9}

y = \frac{8}{9} x +\frac{23}{9} ← in slope- intercept form

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

rearrange the slope- intercept equation into this form

multiply through by 9

9y =  8x + 23 ( subtract 9y and 23 from both sides )

8x - 9y = - 23 in standard form
