Step-by-step explanation:
use point slope form ----> y-y,=m(x-x,)
(the commas serve as ones)
y-4= -2(x-1)
use distributive property
y-4= -2x+2
add 4 to each side
y= -2x+6

Using the Pythagorean Theorem, it is found that the side length is of x = 6.93.
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In this problem, we have that:
[tex]h = 13, l_1 = 11, l_2 = x[/tex]
Hence, applying the Theorem:
[tex]h^2 = l_1^2 + l_2^2[/tex]
[tex]13^2 = 11^2 + x^2[/tex]
[tex]x^2 = 169 - 121[/tex]
[tex]x = \sqrt{48}[/tex]
x = 6.93.

3x+6x+14=41
Solving Multi-Step Equations by Combining Like Terms
Answer:
x = 3
Step-by-step explanation:
Given
3x + 6x + 14 = 41, that is
9x + 14 = 41 ( subtract 14 from both sides )
9x = 27 ( divide both sides by 9 )
x = 3
Answer:
x=3
Step-by-step explanation:
3x+6x+14=41
9x + 14 = 41
- 14 = - 14
9x = 27

A streetlight that is 10 feet tall casts a 2.5-foot-long shadow. A nearby flagpole casts a 9-foot-long shadow. What is the height of the flagpole?
Answer:
The height of the flagpole is 36 feet
Step-by-step explanation:
The given parameters are;
The height of the street light = 10 feet
The shadow cast by the streetlight = 2.5 feet
The shadow cast by the flagpole = 9 foot
The height of the flagpole is given as follows;
The height of the street light/(The shadow cast by the streetlight) = (The height of the flagpole)/(The shadow cast by the flagpole)
∴ The height of the flagpole = (The shadow cast by the flagpole) × (The height of the street light)/(The shadow cast by the streetlight)
By substituting the values, we get;
The height of the flagpole = 9 ft. × 10 ft./2.5 ft. = 36 feet
The height of the flagpole = 36 feet.

The sum of two numbers is 18. 5 times the first number subtracted from 4/7 of the second number is 14. Find the number.
Answer:
The sum of two numbers is 18.
5 times the first number subtracted from 4/7 of the second number is 14.
First number --> x
Second number --> y
so
x + y = 18 --> x = 18-y
5x - (4/7)y = 14
so
5 (18-y) - (4/7)y = 14
90 - 5y - 4/7 y = 14
-5.57 y = 14-90
y = 13.64
so
x = 18 - 13.64
x = 4.36

A scale drawing of a rectangular flag is 12 inches long and 8 inches wide. If the scale is 1 inch: 2.4 feet, what is the length and width of the actual flag?
Answer: length = 28.80 feet
Width = 19.20 feet
Step-by-step explanation:
Scale used = 1 inch:2.4 feet
Length or scale drawing = 12 inches
Width of scale drawing = 8 inches
Length of actual flag = (12 × 2.4 feet) = 28.80 feet
Width of actual flag = (8 × 2.4 feet) = 19.20 feet.
Answer:Answer: length = 28.80 feet
Width = 19.20 feet
Step-by-step explanation
Scale used = 1 inch:2.4 feet
Length or scale drawing = 12 inches
Width of scale drawing = 8 inches
Length of actual flag = (12 × 2.4 feet) = 28.80 feet
Width of actual flag = (8 × 2.4 feet) = 19.20 feet.
The sanctuary’s gift shop purchases items for the amount shown in the table. Leo marks up the cost of each item by 45% to determine the gift shop’s selling price. How much would a customer pay for one pair of binoculars and one bird guide after the mark-up and 8.5% sales tax?
Answer:21.50 dollars
Step-by-step explanation:
The customer pays an amount of $26.74 for one pair of binoculars and one bird guide after the mark-up and 8.5% sales tax
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
According to the given, the required solution would be as:
Mark up for binoculars = 10 x 1.45 = 14.50
14.5 x 1.085 = 15.7325 in sales tax
The total cost per binocular is $15.73 ($).
Bird Guide Commission = 7 x 1.45 = 10.15
10.15 x 1.085 = 11.01275 Sales Tax
The total cost per Bird Guide is $11.11 ($).
The addition provides one of each.
⇒ 15.73 + 11.01 = 26.74
Thus, the customer pays an amount of $26.74 for one pair of binoculars and one bird guide after the mark-up and 8.5% sales tax

Step-by-step explanation:
1. Andrew went to FYE to buy music for the band. He spent a total of $112 on 14 music purchases. one Music CDs were on sale for $10 and cassettes were on sale for $3. How much did Andrew pay for each music CD and each cassette tape? Enter your one-sentence interpretation in the space below.
Answer:
Total Money spent on Music CDs = 10 [tex]\times[/tex] 10 = $100
Total Money spent on Cassette tapes = 4 [tex]\times[/tex] 3 = $12
Step-by-step explanation:
Given that:
Total money spent = $112
Number of music purchases = 14
Cost of one Music CD = $10
Cost of one cassette = $3
To find:
How much money was paid for each music CD and each cassette.
Solution:
Let the number of Music CDs purchased = [tex]x[/tex]
Money spent on Music CDs = [tex]\$10\times x[/tex]
Then the number of cassette tapes purchased = [tex]14-x[/tex]
Money spent on cassette tapes = [tex]\$3\times (14-x)[/tex]
As per the question statement:
[tex]10x+3(14-x)=112\\\Rightarrow 10x+42-3x=112\\\Rightarrow 7x=112-42\\\Rightarrow 7x=70\\\Rightarrow x =10[/tex]
Therefore, number of Music CDs purchased = 10
Total Money spent on Music CDs = 10 [tex]\times[/tex] 10 = $100
And number of cassette tapes purchased = 14 - 10 = 4
Total Money spent on Cassette tapes = 4 [tex]\times[/tex] 3 = $12

The plans for a new street show lamp post that are 2.5 inches apart. If the plans use a scale of 0.5 inch = 9 yards, find the actual distance between the lamp posts.
Answer: 45 yards
Step-by-step explanation:
From the question, we are given the information that the plans for a new street show lamp post that are 2.5 inches apart and that the plans use a scale of 0.5 inch = 9 yards,
Since a scale of 0.5 inch = 9 yards is used, the actual distance between the lamp posts will be:
= (2.5inches / 0.5 inches) × 9 yards
= 5 × 9 yards
= 45 yards
