Dividing the average speed by distance will give you 2.5 which is the average speed the hoverboard goes assuming the hoverboard will travel at the same speed the answer is 2.5 minutes.

Answer:

x = -1.5, -1, 2.

Step-by-step explanation:

I am assuming you want to solve this>

Solve 2x ³ + x ² -7x - 6​ = 0

It looks like x = -1 is a solution so we try it:

2*(-1)^3 + (-1)^2 -7(-1) - 6

= -2 + 1 + 7 - 6

= -1 + 1 = 0

So x = -1 is one root.

So (x + 1) must be a factor of P(x)

Now we divide by x + 1:

x + 1)2x ³     + x ²   -7x -  6​( 2x^2 - x - 6  <--- quotient

       2x^3 + 2x^2

                  -x^2  - 7x

                  -x^2  -  x

                             -6x -  6

                             -6x -  6

                              ----------

2x^2 - x - 6 = 0

(2x + 3)(x - 2) = 0

x = -1.5, 2.

Answer:

1/2

Step-by-step explanation:

remember that the formula for the slope of a line is

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

where m is the slope, and the x and y variables are the x-y coordinates of two points. Choose two points on the line:

Point 1 : (-1,3) and Point 2 : (1,4)

Plug in your values:

[tex]m=\frac{4-3}{1-(-1)}[/tex]

[tex]m=\frac{1}{2} \\[/tex]

So the slope of this line is 1/2 !

Answer: The slope is [tex]\frac{1}{2}[/tex].

Answer:

1.) 6 football tickets for $24

Step-by-step explanation:

The situation which leads to a unit cost of $6 per football ticket is; 6 football tickets for $24.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Multiplication is the mathematical operation is used to determine the product of two or more numbers.

We have been given a condition as; a unit cost of $6 per football ticket.

Meaning that;

The cost of one football ticket is 6 dollar

Then The cost of 12 football ticket  = 12 x 6 dollar

                                                  = 72

Therefore, the situation which leads to a unit cost of $6 per football ticket is; 12 football tickets for $72.

5) The height of a rocket after it is launched

For this case, what you should do is remember the kinematics expressions where we have:

a

v = a * t + vo

y = a * t ^ 2 + vo * t + i

Where,

a: acceleration

v: speed

y: vertical position

t: time

vo: initial speed

yo: initial position

We observe that the expression for the given position is given by a quadratic expression.

Answer: 7 and 8

Step-by-step explanation:

Square root and squared cancel out

Answer:

a=7

b=32

Step-by-step explanation:

The first one (a) is 7 because if you square a square root, you get the number inside the root. Also, technically a square root has an exponent of (1/2) so when you have a power-to-a-power (power rule of exponents) you multiply the exponents. So ([tex]7^{1/2}[/tex])^2 is 7.

For (b) you have to take it in two parts. Square the square root and you get 2. Square the 4 in front, you get 16. Multiply those two numbers (16 and 2) together and you get 32.

Answer:

Adrian lives closer to the school by A. 1,250 meters.

Step-by-step explanation:

1 kilometer = 1,000 meters

So, if Kevin's home is 2 kilometers from the school, then it is also 2,000 meters away, since  1,000 x 2 = 2,000.

Adrian lives 750 meters, or 0.75 kilometers away from school.

2,000 - 750 = 1,250.

Therefore, Adrian lives closer to the school by A. 1,250 meters.

Hope this helps! :D
