Question 7 = 2 Points

Mathematics
1 answer:
anastassius [24]2 years ago
8 0

Answer:

  • See below

Step-by-step explanation:

The budget is $600.

<u>Samantha spends the following amount:</u>

  • 399.95 + 3*7.01 + 34.06 = 455.04

Now, she plans to buy w outfits which cost $75.88 each.

<u>The inequality for this is:</u>

  • 455.04 + 75.88w ≤ 600

<u>Solving this we get:</u>

  • 75.88w ≤ 600 - 455.04
  • 75.88w ≤ 144.96
  • w ≤ 144.96 / 75.88
  • w ≤ 1.91

w = 1 is the only integer solution greater than zero

Write the equation of a line that is parallel to the line 2x - 3y = 5 and passes through the point (2, -1)
jek_recluse [69]

Answer:

The equation of the line is 2x - 3y = 7 ⇒ answer A

Step-by-step explanation:

* Lets revise the relation between the parallel lines

- If two lines are equal then their slopes are equal

- We can make an equation of a line by using its slope and

 a point on the line

- If the slope of the line is m and passing through the point (x1 , y1),

 then we can use this form [y - y1]/[x - x1] = m to find the equation

* Lets solve the problem

- The line is parallel to the line 2x - 3y = 5

∴ the slope of the line = the slope of the line 2x - 3y = 5

- Rearrange the terms of the equation to be in the form

  y = mx + c to find the slope of it

∵ 2x - 3y = 5 ⇒ subtract 2x from both sides

∴ -3y = 5 - 2x ⇒ divide two sides by -3

∴ y = 5/-3 - 2x/-3 ⇒ y = 2/3 x - 5/3

∴ The slop of the line is 2/3

∵ The line passes through point (2 , -1)

* Lets use the rule to find the equation of the line

∵ y - (-1)/x - 2 = 2/3

∴ y + 1/x - 2 = 2/3 ⇒ by using cross multiplication

∴ 3(y + 1) = 2(x - 2) ⇒ open the brackets

∴ 3y + 3 = 2x - 4 ⇒ put x an d y in one side

∴ 2x - 3y = 3 + 4

∴ 2x - 3y = 7

* The equation of the line is 2x - 3y = 7

HELP ASAP PLEASE!!! 20 POINTS!!
Kobotan [32]

Answer: S_{12}=399.90

Step-by-step explanation:

You know that the formula to find the sum of a finite geometric series is:

S_n=\frac{a_1(1-r^n)}{1-r}

Where n is the number of terms, a_1 is the first term and r is the common ratio (r\neq 1).

The steps to find the sum of the first 12 terms of the given geometric serie, are:

1. Find the common ratio "r". By definition:

r=\frac{a_2}{a_1}

Then:

r=\frac{100}{200}\\\\r=\frac{1}{2}

2. Finally, knowing that:

a_1=200\\\\n=12

You must substitute values into the formula.

Then you get:

S_{12}=\frac{200(1-(\frac{1}{2})^{12})}{1-\frac{1}{2}}\\\\S_{12}=399.90
