If a scattergraph contains points that do not fall in a perfect line: Multiple Choice a straight line can still be used to approximate the relationship if a general linear trend can be discerned. the relationship between the variables is not good enough to warrant fitting a line to the data. this is an indication that there is no relationship whatsoever between the variables. the visual fit method and high-low methods should not be used, but least-squares regression can be used.

x > 2

Answer:

(-2,-1)

Step-by-step explanation:

The point (-2, -1) lies on the graph of  y=x²-5

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given function is y=x²-5

A relation is a function if it has only one y-value for each x-value.

We have to find the points which lies on the graph of  y=x²-5

The graph is a parabola which has vertex of (0, -5)

Let us find few points of function

When x=-2, y=-1

When x=0, y=-5

when x=1, y=-4

when x=2, y=-1

when x=3, y=4

when x=4, y=11

when x=5, y=20

Hence, the point (-2, -1) lies on the graph of  y=x²-5

[tex]D = (7,3)[/tex]

Step-by-step explanation:

Given

[tex]D = (3,7)[/tex]

See attachment for graph

Required

Identify and correct the error

From the attached graph, the coordinate of D is at:

[tex]x = 7[/tex]

[tex]y = 3[/tex]

So:

Allie's mistake is that, she identifies x as y coordinate and y as the x coordinate.

So, the right coordinate is:

Answer:

Area is 10.5

Step-by-step explanation:

We can use the trapezoid formula of

[tex]A = \frac{a+b}{2}h[/tex]

A = (2 + 5) / 2 * 3 = 3.5 * 3 = 10.5

or break it into a rectangle and a triangle (natural split by y axis).

A = 2 * 3 + 3 * 3 / 2 = 6 + 9 / 2 = 6 + 4.5 = 10.5

Answer:

10.5 units²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = OS = 3 , b₁ = OC = 5 , b₂ = SK = 2 , then

A = [tex]\frac{1}{2}[/tex] × 3 × (5 + 2) = 1.5 × 7 = 10.5 units²

Answer:

-1/5

Step-by-step explanation:

I couldn't tell whether or not your question was asking for either the slope intercept form or just the slope.

Your answer would be: y = -1/5x + 3   [if your question is asking for the slope intercept form]

Step-by-step explanation:

Answer:

40 ribbon

Step-by-step explanation:

We need to idenify the ratio which is 1 bow to 4 ribbons, so we times that by ten and we get 10:40 so its 40 ribbons. (Hope it helps)

The amount of ribbon she needs for 10 bows will be 40 feet.

It is given that

As she uses 48 feet of ribbon for 12 bows.

So for one bow, the ribbon will be

[tex]\dfrac{48}{12} =4[/tex]

So now if the size of the ribbon should be the same for the new 10 bows then

Size =[tex]10\times 4=40\ feet[/tex]

Thus the amount of ribbon she needs for 10 bows will be 40 feet

Answer:

4y = 6x + 40

Step-by-step explanation:

The general equation of a straight line is y = mx + b

m is the slope and b is the y-intercept

let us write both equations in this form;

we have this as;

6y = -4x + 1

y = -4x/6 + 1/6

and;

2x + 3y = 18

3y = -2x + 18

y = -2x/3 + 6

So firstly we want to find an equation that is perpendicular to the first

When two lines are perpendicular, their slopes has a product of -1

The slope of the first line is -4/6

let the slope of the line we want be m

As per they are perpendicular;

-4/6 * m = -1

-4m/6 = -1

-4m = -6

m = 6/4

So now, we want the y-intercept greater than that of the second equation which is a y-intercept of 6

we can choose 10

and we have the equation as:

y = 6x/4 + 10

multiply through by 4

4y = 6x + 40

Answer:

2/7 is the scale factor.

Step-by-step explanation:

All you have to do is get two sides that are equal to each other. Let's say Side SR and YX. 3 and 10.5. Do 3/10.5, which is 30/105, which simplified is 6/21, which again simplified is 2/7. So, the scale factor is 2/7.

Answer:

106 - 24 = 82

Step-by-step explanation:

b = 106, solve 106 - 24 and you get 82.

Hope this helped.

Answer:

b/24=82

Step-by-step explanation:

Since the difference of an equation is the outcome of division we place 82 as the answer.  

Also, since 82 is greater than 24 we can assume that the variable "b" is larger than both 82 and 24.

Step-by-step explanation:

Since a and b are being multiplied, we can just right ab. Since 4 and c are being multiplied, we ca just right 4c.

Answer:

ab=4c

Step-by-step explanation:

Basically, if you see any variables that are together like that or numbers side by side with letters, it means it's just being multiplied! This doesn't however, work with numbers next to numbers. So for example:

Say you have a x b = 5 x 5c

It would be ab = 5 x 5c Because only letters get put next to each other. That's really the only way I know how to explain it. Have a great day and good luck!
