Please answer: is y = 4x - 9 a function?

Answer:

183

Step-by-step explanation:

Answer:

y = 6x - 4

Step-by-step explanation:

Slope formula: y = mx + b

m = slope, found by figuring out the change in y over the change in x. A fancy way to say find the simplest rate of how far up it goes over how far right it goes. In this case, the line goes up 6 for every time it goes right one; 6/1. This can be simplified as 6.

b = y-intercept, meaning where the line crosses the y line. In this line, you can see that it crosses at -4.

Answer:

D. 216

Step-by-step explanation:

What I did was I multiply 9x9x8 and got 648. I then divide 648 by 3 and got 216. I would appreciate it if you can mark this the brainliest if you can.

The volume of the regular pyramid is V = 216 units³

The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.

Volume of Pyramid = ( 1/3 )a²H

Given data ,

Let the volume of the pyramid be represented as V

Now , the equation will be

Let the height of the pyramid be H = 8 units

Let the side length of the pyramid a = 9 units

Now , Volume of Pyramid = ( 1/3 )a²H

On simplifying , we get

The volume of pyramid V = ( 1/3 ) ( 9 )² ( 8 )

The volume of pyramid V = ( 27 ) ( 8 )

The volume of pyramid V = 216 units³

Hence , the volume of the pyramid is 216 units³

Answer:

The similar figures are shown in the attached drawing created with Microsoft Visio;

The similar figures are the rectangles in figures 2, and 5

Step-by-step explanation:

The given figure is a rectangle with dimensions of 3 yd. by 9 yd., therefore the length = 3 × The width of the rectangle

1) The 9 yd. by 18 yd. figure is a rectangle with the length = 2 × The width of the rectangle, therefore, the figure is not similar to the given rectangle

2) The 3 yd. by 1 yd. figure is a rectangle with the width = 3 × The length of the rectangle, therefore, the figure is similar to the given rectangle

3) The figure is a trapezium, while the given figure is a rectangle, therefore, they are not similar

4) The 6 yd. by 3 yd. figure is a rectangle with the width = 2 × The length of the rectangle, therefore, the figure is not similar to the given rectangle

5) The 6 yd. by 18 yd. figure is a rectangle with the length = 3 × The width of the rectangle, therefore, the figure is similar to the given rectangle

6) The 2 yd. by 8 yd. figure is a rectangle with the length = 4 × The width of the rectangle, therefore, the figure is not similar to the given rectangle

Answer:

∠A is 55°

∠B is 125°

∠C is 55°

∠D is 125°

Step-by-step explanation:

The two acute angles in a parallelogram are equal, and the two obtuse angles are equal too. The angles in all quadrilaterals add to 360°. Since You're given one of the obtuse angles, multiply that number by 2 (125 × 2 = 250) , then subtract that from 360 (360 - 250 = 110) for the value of BOTH acute angles. Divide that by 2 for each individual acute angle (110/2 = 55)

Answer:

1.

Step-by-step explanation:

sec 16° cosec 74° - cot 74° tan 16°​

= 1/ cos 16 * 1/ sin 74 - 1/tan 74 * tan16

= 1/ cos16 sin 74 -  cos74/ sin74 *  sin 16 / cos 16

Now cos 16 = sin 74  and sin 16 = cos 74  (supplementary angles) so:

= 1 / cos^2 16   - sin 16/cos 16 * sin 16 / cos 16

=( 1 - sin ^2 16 )/ cos^2 16

= cos^2 16 / cos^2 16

= 1.

Complete Question:

Mrs. Roberts plants tomatoes and radishes in the areas shown in the model below.

[tex]Tomatoes: 35\ acres[/tex]

[tex]Radishes: 28\ acres[/tex]

Which expression is equivalent to the sum of the two areas?

Answer:

[tex]A + B = 63[/tex]

Step-by-step explanation:

Given

Represent the area of Tomato with A and area of Radish with B

So:

[tex]A = 35[/tex]

[tex]B = 28[/tex]

The sum of the two areas is therefore:

[tex]Sum = A + B[/tex]

Substitute 35 for A and 28 for B

[tex]Sum = 35 + 28[/tex]

[tex]Sum = 63[/tex]

So, you either represent the model as:

[tex]Sum = 63[/tex]

or

[tex]A + B = 63[/tex]

Step-by-step explanation:

On the picture above.

Answer: Dad = 3 hours

Mom = 11 hours

Step-by-step explanation:

Let the number of hours driven by her mum be m.

Let the number of hours driven by her dad be d.

We can form equation from the question as:

d + m = 14 ........... i

60d + 65m = 895.......... ii

Since d + m = 14, d = 14 - m

Substitute 14 - m into d in equation ii

60d + 65m = 895

60(14 - m) + 65m = 895

840 - 60m + 65m = 895

840 + 5m = 895

5m = 895 - 840

5m = 55

m = 11

The mother drove for 11 hours

Since d + m = 14

d + 11 = 14

d = 14 - 11

d = 3

The father drive for 3 hours

Answer:

410 minutes

Step-by-step explanation:

Given that:

Time for which Jesse practices trumpet in the first week = 165 minutes

Time for which Jesse practices trumpet in the second week = 245 minutes

To find:

The total amount of time rounded to the nearest 10 minutes.

Solution:

To find the total amount of time for which Jesse practices, we need to add the time taken for practice in the first week and the time taken for practice in the second week.

Therefore, total time taken = 165 + 245 = 410 minutes

It is already rounded off to the nearest 10 minutes.

Therefore, the answer is:

Total amount of time for which Jesse practices = 410 minutes

B. Intersecting

Step-by-step explanation:

If you were to extend the lines, they would cross eachother

The given lines are intersecting.

When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.

As, from the figure we can see that the line p and q are not parallel to each other because the distance between them is not constant.

Now, the lines are not either skew or perpendicular.

If we extend the lines p and q then will meet at some point which is know as intersecting lines.
