y=3x+3

Step-by-step explanation:

The m is 3 because it is rise over run. For every 3 up it goes one over (3/1) or just 3. The b is 3 because b is where x equals 0 and it is at 3.

Answer:

I believe it would be -20 because the number line values skip by 2 or 3 each skip.

Using the relative frequency concept, it is found that:

A relative frequency is given by the number of desired outcomes divided by the number of total outcomes.

The number in the cell has bounds conversible and Pluto Cars, and the table represents the amount earned, that is, revenue, hence option b is correct.

The total revenue of Pluto Cars is of $80 million, with convertibles corresponding to $18 million, hence the relative frequency is given by:

r = 18/80 = 0.225.

Based on the attached photo and explanation below, the price should not be increased at all.

Note: See the attached photo for the calculation of Revenues at Different Number of Customers and Prices.

Every other being equal, profit is maximized when revenue is at the maximum,

From the attached photo, it can be seen that revenue is at the maximum or the highest when the price is $10 and the number of customers is 1,000.

Increasing the price in increments of a dollar results in a fall in revenue progressively until it reaches $0.

Therefore, the price should not be increased at all.

The general formula for a tangent and secant is

tangent^2 = external segment * full length of the secant.

Givens

tangent length = x

external segment = 7

secant length = 7+ 21

Formula

x^2 = 7 * (7 + 21)                         Remove brackets

x^2 = 7 * 28                                Combine

x^2 = 196                                    Take the square root of both sides

√x^2 = √196

Answer:

[tex]x = - 5 [/tex]

Step-by-step explanation:

To work out this question you have to first cross multiply.

[tex] \frac{2}{5} = \frac{(x - 3)} {(7x + 15)} \\ \\ 2(7x + 15) = 5(x - 3)[/tex]

When you cross multiply you will get the equation above. Therefore

[tex](2 \times 7x) + (2 \times 15) = (5 \times x) \\ - (5 \times 3) \\ \\ 14x + 30 = 5x - 15 \\ \\ 14x - 5x = - 30 - 15 \\ \\ 9x = - 45[/tex]

Therefore

[tex] \frac{9}{9} x = \frac{ - 45}{9} \\ \\ x = - 5[/tex]

Answer:

x = -5

Step by step:

multiply both side by 7x + 15.

2/5 (7x+15)= x − 3

Simplify 2)5 (7x+15) to 2(7x+15)/5.

2(7x+15)/5= x - 3

multiply both sides by 5.

2(7x+15)= 5x - 15

Expand.

14x+30= 5x - 15

subtract 5x from both sides.

14x+30−5x= − 15

Simplify 14x + 30 - 5x14x + 30−5x to 9x + 309x + 30.

9x+30= - 15

Subtract 30 from both sides.

simplify

x = -5

The number of the grass squares of 1 square foot will be 480.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called as the area of the rectangle.

The total area covered by the grass will be:-

A  =  L  x   W

A  =  24  x  20 = 480 square feet

Number of the grass squares having an area of 1 square foot:-

N   =   Total area / area of one grass square

N   =  480 square feet   /   1 square feet

N   =  480

Therefore the number of the grass squares of 1 square foot will be 480.

The length of Seneca between Mesa and La Paz Dr is = 144ft.

The driver of the Seneca Street was driving at 0.75 mi/hr therefore he was with the speed limits.

The maximum length of the skid marks left of Seneca Street by a car that travels within the speed limit is = 144ft

Length of Mesa (a)= 308ft

Length of La Paz Dr (c)= 340ft

Length of Seneca =b

Using Pythagorean theorem,

c²= a² + b²

340²= 308² + b²

make b the subject formula,

b² = 340² - 308²

b² = 115,600 - 94,864

b²= 20736

b = √20736

b = 144ft.

The speed limit within the Seneca road(s) = 50mi/h

The coefficient of friction (f) based on the surface material = 0.7 (asphalt).

The distance covered by the car = 144ft to miles = 144/5280 = 0.027.

Therefore the speed of car(s)

Answer: 9,156.24 ft³

Step-by-step explanation:

The formula for the volume of a cylinder is V = πr²h. The problem gives us both the radius and the height, so we have all necessary values to solve by substitution:

r = 9

h = 36

V = π(9)²×36

= 81 × 36 × π

= 2916π

He will reach the dance before time if he leaves at 16:40.

The formula for speed is speed = distance ÷ time.

To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

Given distance= 120 Km, speed= 100 km/h

For this speed,

time= distance/ speed

       = 120/100

        = 1.2 hours

If the guest leave at 4:40 p.m. then by the speed of 100 km/h he will reach the venue at 06:00 p.m.

The critical points for the inequality x²-5x+6 is x= 2 and x = 3.

In calculus, a critical point of a function is a point where the derivative of the function is either zero or undefined.

These points are important in determining the maximum and minimum values of a function, and can also help identify points of inflection and other important features of a curve.

To find the critical points for the inequality x²-5x+6, we need to find the values of x that make the expression equal to zero (i.e., the roots of the quadratic equation).

We can factor the expression as (x-2)(x-3) and set each factor to zero to find the critical points:

x-2 = 0 or x-3 = 0

x = 2 or x = 3

So the critical points are x = 2 and x = 3.

Therefore, the answer is x= 2 and x = 3.
