1. Lenas total pay if she sells 25 copy is $3050.

2. The copy sold is 34.

From the information given, Lena is a software salesperson. Her base salary is $1800 and she makes $50 more for every copy of English is Fun she sells.

It should be noted that the total pay, P after selling c copies is given by:

P = 50c + 1800

c = number of copies

The pay for 25 copies will be:

P = 50c + 1800

P = 50(25) + 1800

P = 1250 + 1800

P = 3050

When lenas total pay is 3500 the copys did she sell will be:

50x + 1800 = 3500

Collect like terms

50x = 3500 - 1800

50x = 1700

Divide

x = 34

The copy is 34.

Answer:

Approximately twenty-three and a half.

Step-by-step explanation:

sum of two interior angles is equal to one exterior angle....this implies that,

(6x+4) +(5x+2)= 12x-4

11x+6=12x-4.......make X the subject

11x-12x=-4-6

-x= -10......divide both sides by -1

x=10

Answer:

Step-by-step explanation:

The system has infinitely many solutions if the two equations are equivalent.

We can analyze the given systems to see:

A)

Different slopes, there is one solution

B)

Different slopes, there is one solution

C)

Same lines, infinitely many solutions

D)

Different slopes, there is one solution

Solution:

When two equations are equivalent, it is infinitely many solutions because the two lines overlap each other.

Option A - 2x + 7x + y = 6 and y = 9x + 6

Option B - y = 5x + 7 and y = 2x + 8

Option C - y = x + 4 and 2y = 2x + 8

Option D - 7x - y = 10 and y = 6x + 8

Hence, Option C is correct.

The equation can be used to represent statement 'Sixteen is the same as one and two-tenths times a number added to negative 8' is,

[tex]16=1.2n+(-8)[/tex]

Algebraic equation are the expression which consist the variables, coefficients of variables and constants.

The algebraic equation are used represent the general problem in the mathematical way to solve them.

Steps to write down the simple algebraic equation from statement-

Given information-

The given statement is  'sixteen is the same as one and two-tenths times a number added to negative 8'.

The statement given in the problem is talking about a unknown number. Let the unknown number is [tex]n[/tex].

The number is sixteen is the same as one and two-tenths times a number added to negative 8.

This means when our number n, multiplied by the fraction 2/10, and added by the negative 8, then it becomes equal to the number 16. Mathematically,

[tex]16=n+\dfrac{2}{10}\times n+(-8)\\16=1.2n+(-8)[/tex]

Thus the equation can be used to represent the given statement is,

[tex]16=1.2n+(-8)[/tex]

Answer:

y= -6x

Step-by-step explanation:

As you move up vertically  from your y-intercept (0,0) six times, you can see that your x-intercept increased by -1. Because your x-intercept has increased by -1, there is a negative sign in front of 6x

There is no number after -6x because the place where your line meets the y-axis (y-intercept) is (0,0).

Hi there!

8.

Recall the following properties:
[tex]\frac{1}{x^{-a}} = x^a\\\\x^0 = 1[/tex]

Thus, we can rearrange the expression in parts.

[tex](3x)^0 = 1\\\\x^4 = x^4\\\\y^{-4} = \frac{1}{y^4}\\\\\frac{1}{x^{-3}} = x^3\\\\\frac{1}{y^{-7}} = y^7[/tex]

Now, combine these terms:

[tex](1) * x^4 * \frac{1}{y^4} * x^3 * y^7 = \frac{x^4 * x^3 * y^7}{y^4}[/tex]

More properties:
[tex]x^a * x^b = x^{a + b}\\\\\frac{x^a}{x^b} = x^{a - b}[/tex]

Rewrite:
[tex](1) = x^{4 + 3} * y^{7 - 4} = \boxed{\text{D) } x^7y^3}[/tex]

9)

Begin by solving the inside of the parenthesis.

[tex](3^2 + 3^0)^2 = (9 + 1)^2 = 10^2 = 100\\\\(6^{-2} + 3)^0 = 1\\\\100 - 1 = \boxed{ \text{ B. 99}}[/tex]

10)

Simplify the inside of the parenthesis using the above properties.
[tex](\frac{x^2y^5z^3}{xy^7})^{-2} = (\frac{xz^3}{y^2})^{-2}[/tex]

Since there is a negative in the outside exponent, we must take the reciprocal. (flip the numerator and denominator).

[tex]=( \frac{y^2}{xz^3})^2[/tex]

Square both the numerator and denominator.

Recall the property:
[tex](x^a)^b = x^{ab}[/tex]

[tex]= \frac{y^{2*2}}{x^2 * z^{3 * 2}} = \boxed{ \text{C. }\frac{y^4}{x^2z^6}}[/tex]

[tex]x\\[/tex]Answer:

[tex]x=-2[/tex]

Step-by-step explanation:

[tex]x+4=2[/tex]

we want to solve for [tex]x[/tex] so we will let [tex]x[/tex] alone and we will move [tex]4[/tex] to the other side of the equation with an opposite sign ( if it was positive then it will move to the other side with a negative sign, and the opposite is correct ):

[tex]x=2-4[/tex]

solve :

[tex]x=2-4 \\x=-2[/tex][tex]x=2-4[/tex]

[tex]x=-2[/tex]

now [tex]x[/tex] is equal to [tex]-2[/tex]

Answer:

x = -2

Step-by-step explanation:

x + 4 = 2

Answer:

A.) Y= 8
B.) X= 9
