Answer:

Nickels; 5 cents

Dimes; 10 cents

Given that she has 30 nickels:

30(nickels) x 5(a single nickel) = $1.50

2.40 - 1.50 = $0.90, those 90 cents leftovers should then be divided by 10 cents because one dime contains 10 cents and you want to figure out how many dimes there are:

90/10 = there are 9 dimes

Answer:

explanation:

y - 1 = -4(x + 3)

y = -4x - 12 + 1

y = -4x - 11

For find y-intercept, x will be 0

y = -4(0) - 11

y = -11       [ 0, -11 ]

For find x-intercept, y will be 0

0 = -4x - 11

11 = -4x

x = -2.75  [ 2.75 , 0 ]

Plot these two point and draw a straight line. You are done with your task.

The difference in the price per bag for 150 bags versus 50 bags is $0.05 per bag

An equation is an expression that shows the relationship between two or more variables and numbers.

From the diagram:

Price for 150 bag = $38

Cost per bag = $40 / 150 = $0.25

Also:

Price for 50 bag = $15

Cost per bag = $15 / 50 = $0.30

Difference in price = $0.30 - $0.25 = $0.05

[tex]\mathrm{slope\:intercept\:form:\:y = \dfrac{ 1 }{ 2 } x+4}[/tex]

Step-by-step explanation:

To change the equation into slope-intercept form, we write it in the form y=mx+b

So this means that we have to solve for "y" in the equation "-x + 2y = 8"

−x + 2y = 8

Step 1: Add x to both sides

2y = 8 + x

Step 2: Now the equation is in standard form

2y = x + 8

Step 3: Divide both sides by 2

[tex]\mathrm{\dfrac{ 2y }{ 2 } = \dfrac{ x+8 }{ 2 }}[/tex]

Step 4: Dividing by 2 undoes the multiplication by 2

[tex]\mathrm{y = \dfrac{ 1 }{ 2 } x+4}[/tex]

Answer:

14 cm

Step-by-step explanation:

1. Recognize that an isosceles triangle will have at least two equal sides. Given the wording of the problem, we can say that we have two equal sides of 4 cm and a third side of 6 cm

2. Define perimeter. The perimeter of a triangle is the length of the continuous line outlining the triangle

3. Add all three side lengths together (4 cm + 4 cm + 6 cm). This will equal 14 cm

The line of best fit of the student model shows the relationship between variables on a scatter plot

The question is incomplete; So, I will make use of a dataset with the following calculation summary from a graphing calculator

So, the equation of the line of fit is:

[tex]y = -0.1x + 50[/tex]

In (a), we have:

So:

The slope means that the number of students reduces each year by a factor of 0.1, while the y-intercept means that the initial number of students is 50

This means that x = 11.

So, we have:

[tex]y = -0.1*11 + 50[/tex]

[tex]y = 49[/tex]

Hence, the number of students in year 11 is 49

Answer:

  D, E

Step-by-step explanation:

Each vector represents the horizontal and vertical translation amounts:

  [tex]\left[\begin{array}{c}\text{translation right}\\\text{translation up}\end{array}\right][/tex]

Translation left or down will result in negative values for the corresponding translation amounts.

__

We can consider only the lower-left corner to determine the amount of translation.

horizontal: 1 to -4, so -4-1 = -5 units

vertical: 2 to 0, so 0 -2 = -2 units

The translation vector is ...

  [tex]\left[\begin{array}{c}\text{-5}\\\text{-2}\end{array}\right]\qquad\text{matches choice D}[/tex]

__

horizontal: -4 to -1, so -1 -(-4) = -1 +4 = 3 units

vertical: 0 to -4, so -4 -0 = -4 units

The translation vector is ...

  [tex]\left[\begin{array}{c}\text{3}\\\text{-4}\end{array}\right]\qquad\text{matches choice E}[/tex]

Answer:

Question 1

Given expression:

[tex]-2x^3 (4x^3+5x^6)[/tex]

Apply the distributive law [tex]a(b+c)=ab+ac[/tex]:

[tex]\implies -2x^3 \cdot4x^3+-2x^3 \cdot 5x^6[/tex]

Multiply the numbers:

[tex]\implies -8x^3 x^3-10x^3 x^6[/tex]

Apply exponent rule  [tex]a^b \cdot a^c=a^{b+c}[/tex]

[tex]\implies -8x^6-10x^9[/tex]

In standard form we write it in order from the greatest degree:

[tex]\implies -10x^9-8x^6[/tex]

Therefore, as the polynomial is degree 9, it is a nonic polynomial.

End behaviors

As the leading coefficient is negative and the leading degree is odd:

[tex]f(x) \rightarrow + \infty \textsf{, as } x \rightarrow - \infty[/tex]

[tex]f(x) \rightarrow - \infty \textsf{, as } x \rightarrow + \infty[/tex]

Question 2

Factor the given function to find the zeros

Given function:

[tex]f(x) =x^3+15x^2 +63x+49[/tex]

[tex]f(-1) =(-1)^3+15(-1)^2 +63(-1)+49=0[/tex]

Therefore [tex](x+1)[/tex] is a factor of the function

[tex]\implies x^3+15x^2 +63x+49=(x+1)(x^2+bx+49)[/tex]

                                         [tex]=x^3+(b+1)x^2+(b+49)x+49[/tex]

Comparing coefficients ⇒ b = 14

[tex]\implies x^3+15x^2 +63x+49=(x+1)(x^2+14x+49)[/tex]

Factoring [tex](x^2+14x+49)[/tex]:

[tex]\implies (x^2+14x+49)=(x+7)(x+7)=(x+7)^2[/tex]

Therefore,

[tex]f(x)=(x+1)(x+7)^2[/tex]

To find the zeros, equate to the function zero:

[tex](x+1)(x+7)^2=0[/tex]

Therefore,

[tex]x+1=0 \implies x=-1 \textsf{ with multiplicity 1}[/tex]

[tex]x+7=0 \implies x=-7\textsf{ with multiplicity 2}[/tex]
