Cans of corn are on sale at 10 for $4. What is the cost of 15 cans

Answer:

A the answer is A

Step-by-step explanation:

break them apart put 18 into 10 and 8 and multiply it by 30 10 x 30 equals 300

30 x 8 equals 240 add them up you get 540  do the same with next one  break 15 into 10 and 5 multiply 20 by 5 and you get 100 multiply 20 by 10 and you get 200 add them up and you get 300 now add the final numbers up and you get  840

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

You plug in the points in this equation [tex]\frac{y2-y1}{x2-x1}[/tex]

So [tex]\frac{-2-(-5)}{6-2}[/tex] = [tex]\frac{3}{4}[/tex]

Answer:

2 I think I hope it is right?

it will take about 3 hours to get across the rock

The plot of a function f(x) is symmetric across the y-axis if it is even, meaning f(-x) = f(x) for all x in the function's domain.

The answer is then A because

(-x)² = (-1)² x² = x²

|-x| = |-1| |x| = |x|

cos(-x) = cos(x)

The answer is not

• B because sin(-x) = -sin(x) and (-x)³ = (-1)³ x³ = -x³

• C because -x ≠ x and again because of x³

• D because 1/(-x) = -1/x and again because of sin(x)

Answer: A The mean would increase

Step-by-step explanation:

If the smallest numebr dropped, then the numebr would get increased, since there is no more smallest, and the new smallest is $9.25.

Answer:

3rd option

Step-by-step explanation:

Answer: 20%

Step-by-step explanation:

(part / whole) * 100

(3 / 15) * 100 = 20%

The skirts have been reduced to 20% of their original price.

You are looking for the percentage of the original price that the new price is. This means that you are looking for what percentage of $15 that $3 is:

= New price / Original price x 100%

= 3 / 15 x 100%

= 1/5 x 100%

= 20%

The skirts have therefore been reduced to 20% of their original price.

Answer:

A .x+y=150 y=x+80

B. x=35 y=115

x + (x + 80) = 150

2x + 80 = 150

2x = 70

x =35 practicing the guitar

then put x back in to solve for y

C. no because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.

Step-by-step explanation:

this is my first time answering a question so hope it helps :)

A pair of linear equations to show the relationship between the number of minutes ;

x=Max practices the guitar

y= the number of minutes he practices the piano

x+y=150

y=x+80

The time does Max spend practicing the piano every day:

Subsitute x back in to solve for y.

x+y=150  

35+y=150

y=115

No , it is not possible because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.

Answer:

Step-by-step explanation:

Possible rational zeros are of the form ...

  ±{divisor of the constant term}/{divisor of the leading coefficient}

__

1. Rational zeros will be one of ±{1, 2, 3, 6, 9, 18}/{1, 2}, so will be ...

  {±1/2, ±1, ±3/2, ±2, ±3, ±9/2, ±6, ±9, ±18}

__

2. Rational zeros will be one of {±1, ±2, ±3, ±4, ±6, ±8, ±12 ±24}.

__

3. The pairs of coefficients suggest factoring by pairs:

  f(x) = (2x^3 +2x^2) -(8x +8) = 2x^2(x +1) -8(x +1) = 2(x^2 -4)(x +1)

  f(x) = 2(x -2)(x +2)(x +1)

Zeros of f(x) are 2, -2, -1, values of x that make the factors zero.

__

4. The sum of coefficients is zero, so x=1 is a zero. Factoring that out by any of several means, you find ...

  f(x) = (x -1)(x^2 +2x -8)

The quadratic is factored by looking for factors of -8 that have a sum of 2. (4 and -2 are those)

  f(x) = (x -1)(x +4)(x -2)

Zeros of f(x) are 1, -4, 2.

The attached graph confirms our factoring of the polynomials of questions 3 and 4. For cubic and higher degree, I find a graphing calculator to be quite helpful finding zeros.

Answer:

f(x)= 2x^3 + 2x^2 - 8x -8

Answer:

4.397 * 10⁹

Step-by-step explanation:

(3.700 * 10⁹) + (6.970 * 10⁸)  = (3.700 * 10 * 10⁸ ) + (6.970 * 10⁸)

                                             = (37.00 * 10⁸) + (6.970 * 10⁸)

                                             = (37.00 + 6.970) * 10⁸

                                             = 43.97 * 10⁸

                                             = 4.397 * 10 * 10⁸

                                              = 4.397 * 10⁽¹⁺⁸⁾

                                              = 4.397 * 10⁹

solving by the elimination method

[tex]\begin{bmatrix}7x-y=51\\ x+3y=23\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}x+3y=23\mathrm{\:by\:}7\:\mathrm{:}\:\quad \:7x+21y=161[/tex]

[tex]-[/tex]

[tex]\underline{7x-y=51}[/tex]

[tex]22y=110[/tex]

so

[tex]\begin{bmatrix}7x-y=51\\ 22y=110\end{bmatrix}[/tex]

now solving for y

[tex]22y=110[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}22[/tex]

Answer:

Options (2) and (4)

Step-by-step explanation:

Option (1)

The slope of the graph is 60.

From the graph attached,

Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

         = [tex]\frac{-210}{3.5}[/tex]

         = - 60

False.

Option (2)

y-intercept gives the initial distance, in miles from Exit 34.

True.

Option (3)

y-intercept of the graph is 3.5

Since, y-intercept of the graph is 210.

Therefore, Option (3) is False.

Option (4)

Slope gives the rate, in miles per hour, at which the distance to Exit 34 changes over time.

True.
