Answer: The cost of 16 pencils and 10 notebooks is $5.84.


Explanation: You can solve this using linear systems:

Let X be the cost per pencil, and let Y be the cost per notebook.

(1) 7x+8y=4.15
(2) 5x+3y=1.77

Choose a variable to eliminate. I’ll eliminate X first as an example. To eliminate a variable, you must have the same coefficient beside the variable for both equations.

Equation 1 now becomes:

(3) 35x+40y=20.75

Equation 2 now becomes:

(4) 35x+21y=12.39

Now that you have 35 as a coefficient for X in both equations, you can subtract the two equations to officially eliminate it!

(3)-(4)

19y=8.36
y=0.44

Now that you have the value of Y, substitute that value into either one of the equations to get X.

Substitute y=0.44 in (1)

7x+8(0.44)=4.15
7x+3.52=4.15
7x=0.63
x=0.09

Therefore, the cost per pencil is $0.09/pencil and the cost per notebook is $0.44/notebook.

Almost done lol...

To find the cost of 16 pencils, multiply 0.09*16. That gives you $1.44, which will be the cost of 16 pencils.
The cost of 10 notebooks is 0.44*10, which gives you $4.40. That’s the cost of 10 notebooks.

To find the total price, add these values together!

1.44+4.40=5.84

Therefore, the cost of 16 pencils and 10 notebooks is $5.84.

Hope that helps シ

error uses 1/3 can of wet dog food for his dog,muddy,each day.how many servings will he get from 5 cans of dog food?
Vesnalui [34]
First convert 5 cans of dog food to a fraction
(5*3)/3 = 15/3
15/3 - 1/3 = 14/3
he uses 1/3 a can and so he then has 14 servings.

Write a polynomial functionſ of least degree that has rational coefficients, a leading coefficient of 1, and the zeros 1,3, and
otez555 [7]

Answer:

f(x) = x^{4}  -  8x^{3}  + 24x^{2}  - 32x  + 15

Step-by-step explanation:

First of all, if 2 - i is a zero, then so is 2 + i

All you need to do now is multiply (x - 1)(x - 3)(x - 2 + i)(x - 2 - i)

I will do part of that multiplication

(x - 2 + i)(x - 2 - i) = x^{2} - 2x - xi - 2x + 4 + 2i + xi - 2i - i^{2}

                           = x^{2} - 4x + 5

So, now (x - 1)(x - 3)(x^{2} - 4x + 5) =  x^{4}  -  8x^{3}  + 24x^{2}  - 32x  + 15

I will let you finish that multiplication.  I did some and you can do some.  OK?

Which is the graph of f(x) = (x - 1)(x + 4)?
zheka24 [161]

You can determine this by finding zeros of quadratic function,

(x-1)(x+4)=0\implies x_1=1, x_2=-4.

Which eliminates first and third option.

Now we have up and down parabolas left.

If we factor (x-1)(x+4)=x^2+4x+\dots we find that the coefficient before x^2 determines how it is turned, since its positive its an upward turned parabola hence the answer is the last graph.

Hope this helps.
