Answer:
y = −3x − 23
Step-by-step explanation:
The equation of the line in the slope-intercept form is y= x/3 + 6.
The slope of the perpendicular line is negative inverse: m = −3.
So, the equation of the perpendicular line is y = −3x + a.
To find a, we use the fact that the line should pass through the given point:
−2 = (−3) ⋅ (−7) + a.
Thus, a = −23.
Therefore, the equation of the line is y = −3x − 23.
Answer: y =−3x − 23

Answer:
y = -1x + 1
Step-by-step explanation:
- Plug the values into slope formula:
y2 - y1 / x2 - x1
1 - 0 / 0 - 1
1 / -1
= -1
y = -1x + b
1 = -1(0) + b
1 = 0 + b
1 = b

Answer:
Step-by-step explanation:
Lets call the number n.
So the cube of this number is [tex]n^3[/tex] and the sum of 7 and the cube of this number is [tex]7+n^3[/tex]
The sum of twice a number and 4 is equal to the sum of the number and 3.
Answer:
number = - 1
Step-by-step explanation:
let the number be n then twice the number is 2n , so
2n + 4 = n + 3 ( subtract n from both sides )
n + 4 = 3 ( subtract 4 from both sides )
n = - 1
The number is - 1

$18 less than the original price is $48.
HELP!!
Answer:
i believe itd be 66 dollars :D
hope this helps !!
Step-by-step explanation:
x - 18 = 48
add 48 and 18 and get the answer = $66
The given information is,
→ $18 less than the original price is $48.
Let the value of original price be x.
The equation will be,
→ x - $18 = $48
Let's find the required solution,
→ x - 18 = 48
→ x = 48 + 18
→ [x = 66]
Hence, the original price is $66.

On the first day of class, Willem’s Algebra I teacher agreed to assign no homework for a week to the first student to answer this question: There is a positive two-digit integer that is divisible by the sum of its digits and has exactly five factors. What is the sum of its factors? (This is for my little sister in middle school)
Answer:
81
Step-by-step explanation:
There are only two numbers with 5 factors that are only two digits. 16 and 81 are the only options and when you add 8+1=9 and 81 is divisible by 9.

the measure of the angles of a triangle are shown in the figure below. solve for x.
Answer:
[tex]\boxed {\boxed {\sf x= 12}}[/tex]
Step-by-step explanation:
We are asked to solve for x. We are given a triangle and all 3 angles are labeled. We know that the sum of the angles in a triangle must be 180 degrees. Therefore, the given angles: 81, 57, and (2x+18) must add to 180. We can set up an equation.
[tex]81+57+ (2x+18)= 180[/tex]
Now we can solve for x. Begin by combing like terms on the left side of the equation. All the constants (terms without a variable) can be added.
[tex](81+57+18)+2x=180[/tex]
[tex]156+2x=180[/tex]
We will solve for x by isolating it. 156 is being added to 2x. The inverse operation of addition is subtraction. Subtract 156 from both sides of the equation.
[tex]156-156+2x=180-156 \\2x=180-156 \\2x= 24[/tex]
x is being multiplied by 2. The inverse operation of multiplication is division. Divide both sides by 2.
[tex]2x/2= 24/2 \\x= 24/2 \\x=12[/tex]
In this triangle, x is equal to 12.
Answer:
x° = 12°Step-by-step explanation:
❁ Hello! ❁
The sum of the measures of the angles of a triangle is 180°.
81° + 57° + (2x + 18)° = 180°
138° + (2x + 18)° = 180°
(2x + 18)° + 138° = 180°
2x + 18° = 180° - 138°
2x + 18° = 42°
2x = 42° - 18°
2x = 24°
x° = 24° ÷ 2
x° = 12°
Success! ☺️
Three companies Benfel Ltd, Cromwell Ltd and Samtec Ltd were recently launched in the Kenyan market. The companies have operated in the Kenyan market for a few months now. At the beginning of the month of August 2019, a survey on monthly brand switching behavior was conducted on a representative sample among customers of the three companies. The survey revealed that Benfel Ltd retains 70% of its customers and loses 20% to Cromwell Ltd and 10% to Samtec Ltd. Similarly, Cromwell Ltd retains 60% of its customers and loses 30% to Benfel Ltd and 10% to Samtec Ltd. Furthermore, Samtec Ltd retains 50% while it loses 30% to Cromwell Ltd and 20% to Benfel Ltd. It has been determined that there will be 3,500, 4,300 and 2,200 customers shopping with Benfel Ltd, Cromwell Ltd and Samtec Ltd respectively at the start of the month of September 2019.
i. Evaluate the distribution of the sample surveyed as at the beginning month of August 2019. (5 marks)
ii. Compare the long run state of the market amongst the three companies. (5 marks)
Evaluating the distribution sample surveyed and comparing the long run state of the market of the three companies
i) The distribution of sample as at the beginning month of August is :
Benfel limited = 5000 customers
Cromwell Ltd = 7167 customers
Samtec Ltd = 4400 customers
ii) In the long run Benfel limited will have more customers than Cromwell and Samtec because they both lose more customers to Benfel limited than Benfel loses to them. also Benfel keeps a higher percentage of its customer
i) At the Beginning of the month of August the sample size for each company respectively will be
X * 70/100 = 3500 ∴ x ( sample size at August ) = 5000 ( Benfel )
y * 60/100 = 4300 ∴ y ( sample size at August ) = 7167 ( Cromwell )
z * 50/100 = 2200 ∴ z ( sample size at August ) = 4,400 ( Samtec )
ii) In the long run Benfel limited will have more customers than Cromwell and Samtec because they both lose more customers to Benfel limited than Benfel loses to them. also Benfel keeps a higher percentage of its customers

Find m<1 if <1 is complementary to <2, <2 is supplementary to <3, and
m<3 = 126
Answer:
∠ 1 = 36°
Step-by-step explanation:
Supplementary angles sum to 180° then
∠ 2 + ∠ 3 = 180° , that is
∠ 2 + 126° = 180° ( subtract 126° from both sides )
∠ 2 = 54°
Complementary angles sum to 90° , then
∠ 1 + ∠ 2 = 90° , that is
∠ 1 + 54° = 90° ( subtract 54° from both sides )
∠ 1 = 36°
Points X, Y, and Z are collinear, with Y in between X and Z. If XY = 5x, YZ = 2x + 7, and XZ = 56, find x.x = 7
When two or more points are on a straight path, then they are collinear. So that in the given question, the value of x is 7.
Two or more points are said to be collinear if and only if they fall on a straight line. Thus, the points can be joined by a single straight line.
From the given question, it can be observed that;
XZ = XY + YZ
But given the following:
XY = 5x, YZ = 2x + 7, and XZ = 56
Then,
56 = 5x + (2x + 7)
= 5x + 2x + 7
56 = 7x + 7
collect like terms to have
56 - 7 = 7x
49 = 7x
x = [tex]\frac{49}{7}[/tex]
= 7
x = 7
Therefore, the value of x is 7.
