Constant rate of change of y=4x-3?

10 POINTS

Answer:

-2/3

Step-by-step explanation:

We can use the slope formula when we have two points

m = ( y2-y1)/(x2-x1)

   = ( 4 - -2)/( -5 -4)

   = ( 4+2)/( -5-4)

    = 6/ -9

Simplifying

  = -2/3

Slope:-

Answer:

-10=$35r+$5r

+10=$30r

Step-by-step explanation:

This function represents this situation. If someone orders less than ten rings (-10) then they will pay $35 for each ring($35r) plus dollars for each for shipping ($5r)

If someone were to buy more than ten rings (+10) then they will pay $30 for each ring ($30r)

Have a great day!

Answer:

Step-by-step explanation:

The side opposite the given width of x is also x.

So you have to relate 3 facts.

The angle

The adjacent side

The hypotenuse.

Formula

Cos(28) = x / 35

Solution

Cos(28) = x / 35                Multiply both sides by 35

35 cos(28) = 35 * x / 35   Cancel

35 cos(28) = x                  Multiply

30.90 = x

Rounded, it is 30.9

Answer:30.9 cm

Step-by-step explanation:  =X/35

X= 35 cos 28'

X= 30. 90cm

width 06

Rectangle = 30.9cm

Answer:

dx/dt | (x=3) = 27/2

Explanation:

x*y = 2 ......... (a)

At x = 3, (3)*y = 2 => y = 2/3

Differentiate (a) wrt t,

x.dy/dt + y.dx/dt = 0 ........ (b)

Put x=3, dy/dt=-3 and y=2/3 in the differential equation (b),

3(-3) + (2/3)*dx/dt = 0

dx/dt = (9*3)/2 = 27/2

The necessary step for constructing parallel lines is to draw a line that intersects the first line using a straightedge.

Two lines are said to be parallel in a plane if they do not intersect each other even if extended till infinite in both the directions.

Steps to construct a parallel line using ruler and compass are:

Answer: Irrigation water can come from groundwater, through springs or wells, surface water, through rivers, lakes, or reservoirs, or even other sources, such as treated wastewater or desalinated water. As a result, it is critical that farmers protect their agricultural water source to minimize the potential for contamination.

Answer:

Total pipes = 692 pipes

Step-by-step explanation:

Now we have to,

→ find the amount of pipes he use.

Forming the expression,

→ 610 plastic pipes + 82 metal pipes

Let's solve the problem,

→ 610 plastic pipes + 82 metal pipes

→ 610 + 82

→ 692 pipes

Hence, the farmer used 692 pipes.

Answer:

$ 3.75

Step-by-step explanation:

Let the unknown price be x.

Ounces                                 cost

16                ⇒                  $ 2.50

24                ⇒                   x

Now let us use cross multiplication and find the value of x.

16 × x = 24 × 2.50

16x = 60

Divide both sides by 16.

x = 3.75

Therefore, 24 ounces of bulk rice cost $ 3.75

Answer:

Keep Change Flip. Then, multiply out.

You will get:

x^3 - 9x +2x^2 - 18 / 3x^3 - x^2 - 27x + 9

Now factorise top and bottom to get :

(x+2)(x+3)(x-3) / (3x-1)(x+3)(x-3)

The same bracket at the top and bottom cancels out to give the final answer of:

x+2 / 3x-1

Or

x+2 ÷ 3x-1

Hope this helps!

Use the difference of 2 squares to expand x^2-9 to (x+3)(x-3).

factorizing 3x^2 + 8x -3 gives (3x-1)(x+3). With all these, we can simplify as shown in the picture above

The Answer Is: "5x + 16"

Step-by-step explanation:

Question A-

To find: Greatest number of toys that Paul can buy with $2760

We can simply divide the total money by the toy's price-

total money/toy's price

= 2760 / 9

= 306.6

= 306 (since we cannot buy .6 of a toy we round it off to the previous number)

Question B-

To find: Amount of money left after buying the toys

The remanider of 2760/9 will give us the money left with Paul

Answer:

$11

Step-by-step explanation:

5*2=10 (for 5 yards) plus  1.00 for the 1/2 yard

Answer:

$ 11.00 or 11

Step-by-step explanation:

2.00 X 5 1/2 = 11

You would multiply the cost of $ 2.00 (one yard) with the total yard 5 1/2 and get 11 or $11

So your answer is for a total of 5 1/2 yards it would cost $11.

Answer:

x=6

Step-by-step explanation:

If a line has an undefined slope, then it has to be a vertical line.

Since the line is vertical, there is only one x value for any given y value. This means we can use the x value in the given coordinate pair to find the equation...

Answer:

2 acute angles

Step-by-step explanation:

A right triangle HAS to have a right angle, which is 90 degrees. This means the other two angles must add up to:

180-90 = 90 degrees

Acute angles are LESS than 90 degrees. You cannot add two positive integers over 90 to get 90 (obtuse angles), and you can also not have two 90 degree angles since that forms a straight line, therefore meaning the other two angles must be acute.

Answer:

2

Step-by-step explanation:a normal right triangle has 3 angles in total and looking at the bend in each corner only two of them are acute so that makes it 2

Answer:

So 85 percent of 112
A percentage basically means “out of a hundred”

So 85 percent is 85/100
85/100 is 0.85
KEY word is “of”, we multiply when there’s of
0.85*112= 95.2
95.2 is 85 percent of 112

They are the same :)

[tex] \cos(45) = \frac{ \sqrt{2} }{2} = 0.71(2d.p) \\ \\ \sin(45) = \frac{ \sqrt{2} }{2} = 0.71(2d.p)[/tex]
