I Need Help With This Question

Answers

Answer 1

Divide x by y and compare:

5/1 = 5

10/2 = 5

20/4 = 5

All 3 are the same number so yes the rate of change is constant.

Answer 2

Answer:

Yes

Step-by-step explanation:

We can see that the correlation between x and y is

x = y/5

or

y = 5x

The diameter of the circle is 34cm and a chord is at a distance of 15cm from the centre. Find the length of the chord of the circle

Answers

Answer:  16 cm

===================================================

Explanation:

The drawing is shown below.

Point A = center of circlePoints B,C,E = points on the circle's edgePoint D = midpoint of chord CE

The goal is to find the length of CE based on these facts

BC = 34 = diameterAD = 15 = distance from center to chordx = length of segment CD = length of segment DE

Notice how AB = AC = AE = 17 because they are all radii of the same circle. We cut the diameter in half to get the radius.

Focus on triangle CAD. We'll use the pythagorean theorem to find x.

a^2 + b^2 = c^2

(AD)^2 + (DC)^2 = (AC)^2

15^2 + x^2 = 17^2

225 + x^2 = 289

x^2 = 289 - 225

x^2 = 64

x = sqrt(64)

x = 8

Segment CD is 8 cm long, and so is segment DE.

To wrap things up, we then say:

CE = CD + DE

CE = 8 + 8

CE = 16

Chord CE is 16 cm long.

what does 2y-x=-14 equal?

Answers

Answer:

x=2(y+7)

Step-by-step explanation:

2y−x=−14

Subtract 2y from both sides.

−x=−14−2y

The equation is in standard form.

−x=−2y−14

Divide both sides by −1.

x=2y+14

Then use the inverse property of distrubtion.

x=2(y+7)

or if you want to you can leave it as x=2y+14

Answer:

y=x/2-7

Step-by-step explanation:

Move x to the side with the constant and then divide.

1. -x from both sides

2. the divide by 2

it can also be written like

y=1/2x-7

one of 50 states is chosen at random. What is the probability of not choosing a state that begins with the letter n?

Answers

Answer:

8 states start with the letter N. Because you’re looking for the amount of states not starting with the letter N, we’ll subtract 8 from 50. Then you’ll put that over the total amount of states. So you should end up with 42/50 which will simplify to 21/25. Hope this helped!

Consider the relation {(1,3), (2,5), (-6,-3), (0,0)}. What is the range of the relation?

Answers

Answer:

the domain is:

0

,

1

,

6

}

the range is:

{

2

,

3

,

4

,

6

,

4

}

the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .

Step-by-step explanation:

In the relation:

{

,

(

}

:

The domain:

Is the set of all the first numbers of the ordered pairs.

In other words, the domain is all of the x-values.

So in this case the domain is:

{

3

,

0

,

1

,

6

}

The range:

Is the set of the second numbers in each pair, or the y-values.

So in this case the range is:

{

2

,

3

,

4

,

6

,

4

}

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

So in this case the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .

Answer:

the domain is:  { − 3 , 0 , 1 , 6 }

the range is: { 2 , 3 , 4 , − 6, 4 }

the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .

Step-by-step explanation:

In the relation: { ( − 3, 2) , ( 0 , 3 ) , ( 1 , 4 ) , ( 1 , −6 ) , ( 6 , 4 ) } :

The domain:

Is the set of all the first numbers of the ordered pairs.

In other words, the domain is all of the x-values.

So in this case the domain is: {− 3 , 0 , 1 , 6 }

The range:

Is the set of the second numbers in each pair, or the y-values.

So in this case the range is: { 2 , 3 , 4 , − 6, 4 }

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

So in this case the relation is not a function since it has TWO distinct y values '4' and '-6' for the same x value of '1' .

Find the area of the shape shown below.

Answers

Answer:

28 units.

Step-by-step explanation:

Area of square + Area of triangle + Area of rectangle = Area of figure shown

=> (4 x 4) + (1/2 x 4 x 2) + (2 x 4) = Area of figure shown

=> 16 + 4 + 8 = Area of figure shown

=> 28 = Area of figure shown

Therefore, the area of the figure is 28 units.

Hoped this helped.

Answer:

28 units.

Step-by-step explanation:

Act like the shape is just a normal rectangle, because thats easy to do. If it was a full rectangle the length would be 8 and the width would be 4. The formula for finding area of a rectangle is length times width so 8x4 is 32. Now, to find the actual area of the shape, you have to subtract a bit. (I'll add a picture to better explain what I am meaning) You imagine see a mini rectange in the corner with a length of 4 and a width of 2. The area for that is 8. But, only half of that imaginary rectangle is in the actual shape so subtract half of that shape (4) from the original 32 and you get 28. The area is 28 units.

Answer:

x intercept= (-3,0)  y intercept= (0,3)

Step-by-step explanation:

for x intercepts, y should equal zero

for y intercepts, x should equal zero

x intercept: -x+0=3

-x=3

x=-3  (x,y)--> (-3,0)

y intercept: 0+y=3

y=3 (x,y)--> (0,3)

The x-intercept is the point at which the graph crosses the x-axis.The y-intercept is the point at which the graph crosses the y-axis.Let x be 0.Then, -x + y = 3or, y = 3(x, y) = (0, 3)Now, let y be 0.Then, -x + y = 3or, -x + 0 = 3or, x = -3(x, y) = (-3, 0)So, x-intercepts are 0 and -3 and y-intercepts are 3 and 0.

Answer:

Answer:x - intercept (0, -3)

3)y - intercept (3, 0)
