answer for a lot of points !!!!

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: Quite simply: 2+x

A constant is simply a number, something that does not change: here it's "2"

A variable can change: here it's "x" - anything can be substituted for x

If we put those two together with a "+" sign, we get an expression: variables or constants (including multiple ones: such as 2x, which is a term) added to each other or subtracted from each other

x = 4

Step-by-step explanation:

[tex]2x - 3y = - 1 \: \: \: \: \: ...(*)\\ y = 3[/tex]

Substitute y = 3 into (*).

[tex]2x - 3(3) = - 1 \\ 2x = - 1 + 3(3) \\ 2x = - 1 + 9 \\ 2x = 8 \\ x = 4[/tex]

Answer:

x = 4

Step-by-step explanation:

2x - 3y = -1

y = 3

Substitute the given value for y.

2x - 3 (3) = -1

2x - 9 = -1

2x - 9 + 9 = -1 + 9

2x = 8

2x/2 = 8/2

x = 4

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

To Find:

What is the cost per soda?

Note:

To find cost per soda you have to divide Cost by number of Sodas

Solve:

$175.00/140 = 1.25

Hence, the cost per soda is $1.25

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

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

[tex]9m+2 \\ -(3m+8) \\ - - - - - \\ 6m - 6 \\ - - - - - [/tex]

Solution :-

[tex]9m + 2 - (3m + 8) \\ 9m + 2 - 3m - 8 \\ m(9 - 3) + (2 - 8) \\ 6m - 6[/tex]

Answer:

6m - 6

Step-by-step explanation:

9m + 2 - (3m + 8) = 9m + 2 -3m -8

= 9m - 3m + 2 - 8

= 6m - 6

when you open the brackets, -(+3m) = -3m because when a positive sign times a negative sign, you get a negative sign. so, same thing for -(+8) = -8

Answer:

[tex]x^3[/tex]+67x+5

Step-by-step explanation:

[tex]13^3=2,197[/tex]

anything higher will surpass 2,637 so dividing 2,637 by 13=67.35 so 67x is the next number .35*13=4.55 round up to get 5 so x^3+67+5 is the answer

Step-by-step explanation:

l = 3x - 5

w = 2x + 9

perimeter = 2l + 2w = 2(3x - 5) + 2(2x + 9) =

= 6x - 10 + 4x + 18 = 10x + 8

area = l×w = (3x - 5)(2x + 9) = 6x² + 27x - 10x - 45 =

= 6x² + 17x - 45

Answer:

[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:

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]

The expression that is equivalent to [tex](3a)^{-2}[/tex] is [tex]\frac{1}{9a^{2} }[/tex].

Given expression is [tex](3a)^{-2}[/tex]

[tex]a^{-n} =\frac{1}{a^{n} }[/tex]

So, the given expression [tex](3a)^{-2}[/tex]can be written as [tex]\frac{1}{(3a)^{2} }[/tex]

[tex]\frac{1}{(3a)^{2} }= \frac{1}{3a*3a} =\frac{1}{9a^{2} }[/tex]

Therefore, the expression that is equivalent to [tex](3a)^{-2}[/tex] is [tex]\frac{1}{9a^{2} }[/tex].
