Answer:

The slope is 3

Step-by-step explanation:

The formula for slope is m = (y₂-y₁)/(x₂-x₁)

We assign

Note: You can choose any set of points as long as you assign y₂ and y₁ to y coordinates and x₂ and x₁ to x coordinates.

m = (-1+4)/(0+1) = 3/1 = 3

Answer:

D. 3 :)

Step-by-step explanation:

As the x value increases, so does the y value but in bigger jumps. It increases by 3 :)

The correct values for b is,

⇒ 0 < b < 1

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

F (x) = [tex]log_{b} x[/tex]

Now, We know that;

As the logarithm of a negative number is undefined, b should be a positive number (b>0 ).

Therefore, the value of b must be in the range of 1 > b > 0 for the function to be a decreasing function.

Thus, The correct values for b is,

⇒ 0 < b < 1

A mean is an arithmetic average of a set of observations. The average time taken by Shiho to complete the track is 3.7 seconds.

A mean is an arithmetic average of a set of observations. it is given by the formula,

[tex]\rm Mean=\dfrac{\text{Sum of all obervation}}{\text{Number of observation}}[/tex]

The reading of the 5 trials of Shiho is 3.3 seconds, 3.8 seconds, 4.1 seconds, 4.1 seconds, and 3.1 seconds. Therefore, the average or the meantime of Shiho can be written as,

[tex]\rm \text{Average Time} = \dfrac{\text{Sum of all observations}}{\text{Number of trials}}\\\\\text{Avrage Time} = \dfrac{3.3+3.8+4.1+4.1+3.1}{5}=\dfrac{18.4}{5}= 3.68\approx 3.7\ seconds[/tex]

Hence, the average time taken by Shiho to complete the track is 3.7 seconds.

Solution -

Let the sum of money that was given to each boy be a and the number of boys be b. Hence, the total no. of money distributed to b no. of boys is ab.

According to the question,

Scenario 1 -

➡ (a + 2)(b - 10) = ab

Solving it further,

➡ a(b - 10) + 2(b - 10)= ab

➡ ab - 10a + 2b - 20= ab

Cancelling ab,

➡ 10a - 2b + 20 = 0

➡ 10a = 2b - 20

➡ a = 2(b - 10)/10

➡ a = (b - 10)/5

Scenario 2 -

➡ (a - 2)(b + 15) = ab

Solving it further,

➡ a(b + 15) - 2(b + 15)= ab

➡ ab + 15a - 2b - 30= ab

Cancelling ab,

➡ 15a - 2b - 30 = 0

Substituting the value of a in the equation,

➡ 15{(b - 10)/5} - 2b - 30 = 0

➡ 3(b - 10) - 2b - 30 = 0

➡ 3b - 30 - 2b - 30 = 0

➡ 3b - 2b -60 = 0

➡ b = 60

Substituting the value of b in a = (b - 10)/5,

➡ a = (60 - 10)/5

➡ a = 50/5

➡ a = 10

[Here we have used the substitution method]

Henceforth, the total number of boys is 60 and the sum received by each is Rs. 10 .

Answer:

y = x-3

Step-by-step explanation:

When the graph of this equation crosses the y - axis , the value of x is = 0.

 sub in zero to find this y value = -3

    so the point is (0, -3)

Now find the drivative of this equation....the derivative tells you the slope of the original graph at any given point

 derivative = 12x^2-10x+1        this , when x = 0 shows slope  = 1

    the equation then becomes   y = (1) x -3     or just  y = x-3

For $22.69 dollars I can ride the scooter for 179 minutes.

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

Given, A scooter ride has a starting fee of $3 and then 11 cents per mile.

Assuming with $22.69 I can ride x no. of minutes.

∴ 0.11x + 3 = 22.69.

0.11x = 19.69.

Answer:

[tex]x=\pm1 \:\textsf{or}\:x=\pm3[/tex]

Step-by-step explanation:

[tex]x^4-10x^2+9=0[/tex]

[tex]\textsf{let}\:x^2=y[/tex]

[tex]\implies y^2-10y+9=0[/tex]

To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find 2 two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex].

⇒ two numbers that multiply to 9 and sum to -10:  -9 and -1

Rewrite [tex]b[/tex] as the sum of these 2 numbers:

[tex]\implies y^2-y-9y+9=0[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies y(y-1)-9(y-1)=0[/tex]

Factor out the common term [tex](y-1)[/tex]:

[tex]\implies (y-9)(y-1)=0[/tex]

[tex]\implies (y-9)=0 \implies y=9[/tex]

[tex]\implies (y-1)=0 \implies y=1[/tex]

Change [tex]y[/tex] back to [tex]x^2[/tex]:

[tex]\implies x^2=9\implies x=\pm3[/tex]

[tex]\implies x^2=1\implies x=\pm 1[/tex]

[tex]\textsf{So}\: x=\pm1 \:\textsf{or}\:x=\pm3[/tex]

Answer:

[tex]$x=\pm1\;\textrm{or}\;x=\pm3$[/tex]

Step-by-step explanation:

Substitute [tex]u = x^2[/tex] into the equation. This will make the quadratic formula easy to use.

[tex]\implies u^2 - 10u + 9 = 0[/tex]

Consider the form [tex]x^2 + bx + c = 0[/tex]. Find a pair of integers whose product is [tex]c[/tex] and whose sum is [tex]c[/tex]. In this case, whose product is [tex]9[/tex]and whose sum is [tex]10[/tex]. And write the factored form using the integers.

[tex]\implies (u - 9)(u - 1) = 0[/tex]

If any individual factor on the left side of the equation is equal to [tex]0[/tex], the entire expression will be equal to [tex]0[/tex].

[tex]\implies \begin{cases}u - 9 = 0 \\ \\ u - 1 = 0\end{cases}[/tex]

Set [tex]u - 9[/tex] equal to [tex]0[/tex] and solve for [tex]u[/tex]. Similarly, Set [tex]u - 1[/tex] equal to [tex]0[/tex] and solve for [tex]u[/tex].

[tex]\implies \begin{cases}u = 9 \\ \\ u = 1\end{cases}[/tex]

Substitute the real value of [tex]u = x^2[/tex] back into the solved equation.

[tex]\implies \begin{cases}x^2 = 9 \\ \\ x^2 = 1\end{cases}[/tex]

Take the square root of both sides of the equations to eliminate the exponent on the left side.

[tex]\implies \begin{cases}x = \sqrt{9} \\ \\ x = \sqrt{1}\end{cases}[/tex]

Solve both the equations for the value of [tex]x[/tex].

[tex]\implies \begin{cases}x = \pm3 \\ \\ x = \pm1\end{cases}[/tex]

Hence, this is our required solution for this question.

Answer:

2500 pence (C = 2500)

Step-by-step explanation:

[tex]C = 10t + 20m[/tex]

From the given information, t is the number of texts so essentially you will plug in the number of texts provided (150) in the place of the variable t.

[tex]C = 10(150) + 20m[/tex]

Apply the same thing to minutes, plug in the number of minutes (50) in the place of the variable m.

[tex]C = 10(150) + 20(50)[/tex]

Now multiply the substitutes with the co-efficient.

[tex]C = 1500 + 1000[/tex] (10*150=1500 & 20*50=1000)

Add the addends
