The total amount of income Xander earns from selling y books algebraically is C = 25000 + xy + 0.08y.

An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenarios.

In this situation, Xander writes math textbooks that sell x dollars each, he received a bonus of $25,000 for signing a contract, and he receives 8% commission on each book sale.

c = total amount

y = number of books.

The total amount of income will be:

= 25000 + (x × y) + (8% × y)

= 25000 + xy + (0.08 × y)

C = 25000 + xy + 0.08y

Answer:

x = 8

Step-by-step explanation:

Given

- 4(- x + 8) = 0

- 4≠ 0, so

- x + 8 = 0 ( subtract 8 from both sides )

- x = - 8 ( multiply both sides by - 1 )

x = 8

Answer:

X=8

Answer:

L=8

Step-by-step explanation:

area of a rectangle = length x width

given:

area= 20 square units

width =2.5 units

find the length by substituting :

20=2.5 x L

L= 20/2.5=8

that's it :)

X should equal 11. X=11

x = 11

Hope so this answer guide you to understand

Answer: x - x1/ x2- x1 = y -y1 / y2-y1

x - 6/ -6-6= y - 1/ -1 -1

x -6/-12 = y -1 /-2

-2(x-6) = -12 (y-1)

-2x +12 = -12y +12

12y = 2x +12-12

y= 2x/12

y= x/6

Answer:

[tex]T=0.3142km \\T=0.31km\ to\ 2dp[/tex]

Step-by-step explanation:

Diameter [tex]d=32cm=0.32m[/tex]

Number of rotations [tex]N=100\pi[/tex]

Generally the circumference of the wheel is mathematically given as

[tex]C=2\pi r[/tex]

[tex]C=2\pi (0.32)^2/4[/tex]

[tex]C=1.005309649m[/tex]

[tex]C=1.0m[/tex]

Generally the total distance traveled  T is mathematically given as

[tex]T=N*C[/tex]

[tex]T=100\pi *1m[/tex]

[tex]T=314.1592654m \approx 314.16m[/tex]

Total distance traveled  T in Kilometres

[tex]T=314.1592654m[/tex]

[tex]T=\frac{314.1592654m}{1000}[/tex]

[tex]T=0.3142km \\T=0.31km\ to\ 2dp[/tex]

the answer is 4.6 or 4.60

Answer:

Step-by-step explanation:

On the given graph the period is the distance between maximum points -7 and 3:

Answer:

The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.

From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units

Therefore, 10 units is the right answer.

Step-by-step explanation:

A is equal to 5d-5

I just went through all eh choices

It can’t be b or c becuase when distributed, it automatically is -5d+25 or vice versa with a different sign so their out

D is impossible becuase you can’t jsut flip a subtraction problem

And A is possible because adding a negative basically means subtracting so if flipped The signs have to change
