Answer:
A=x2 - 2x -35
Step-by-step explanation:
x+5 x-7
The solution is Option D.
The area of the rectangle is A = x² - 2x - 35
What is the Area of a Rectangle?
The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of the rectangle be represented as A
Now , the value of A is
The length of the rectangle L = x + 5
The width of the rectangle is W = x - 7
And ,
The area of rectangle = L x W
Substituting the values in the equation , we get
The area of rectangle = Length of rectangle x Width of rectangle
The area of rectangle = ( x + 5 ) ( x - 7 )
On simplifying the equation , we get
The area of rectangle A = x ( x - 7 ) + 5 ( x - 7 )
The area of rectangle A = x² - 7x + 5x - 35
The area of rectangle A = x² - 2x - 35
Therefore , the value of A is x² - 2x - 35
Hence , the area of rectangle is x² - 2x - 35

Hope this helps
Option B is correct, No, j = 9 is not a solution to the inequality j+1>10.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
We can substitute j = 9 into the inequality j + 1 > 10 and see if it is true or false.
j plus one greater than ten.
j + 1 > 10
We have to check whether j=9 is the solution of the given inequality.
Substitute j equal to 9 in the above inequality.
9 + 1 > 10
10 > 10
The inequality is not true when j = 9. Therefore, j = 9 is not a solution to the inequality.
Hence, Option B is correct, No, j = 9 is not a solution to the inequality j+1>10.

Step-by-step explanation:
Given
[tex]Line\ 1: (2, -3), (-4, -6)[/tex]
[tex]Line\ 2: (-3, 2), (2, -8)[/tex]
Required
Tell the relationship between both lines
We start by calculating the slopes (m) of both lines.
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
For Line 1:
[tex]m_1 = \frac{-6 - (-3)}{-4 - 2}[/tex]
[tex]m_1 = \frac{-6 +3}{-4 - 2}[/tex]
[tex]m_1 = \frac{-3}{-6}[/tex]
[tex]m_1 = \frac{1}{2}[/tex]
For Line 2:
[tex]m_2 = \frac{-8 - 2}{2 - (-3)}[/tex]
[tex]m_2 = \frac{-8 - 2}{2 +3}[/tex]
[tex]m_2 = \frac{-10}{5}[/tex]
[tex]m_2 = -2[/tex]
The lines are not parallel because [tex]m_1 \ne m_2[/tex]
However, they are perpendicular, because:
[tex]m_1 = -\frac{1}{m_2}[/tex]
To prove this, substitute values for m1 and m2
[tex]\frac{1}{2} = -\frac{1}{-2}[/tex]
[tex]\frac{1}{2} = \frac{1}{2}[/tex] --- Proved

Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors
Complete question :
In a class of 125 students, 27 are computer science majors, 51 are mechanical engineering majors, 12 are civil engineers and the rest are general engineering majors. Assume students only have one major.
Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors?
Answer:
0.039
Step-by-step explanation:
Total = T = 125
Computer Science = S = 27
Mechanical Engineering = M = 51
Civil Engineering = C = 12
General engineering, G = 125 - (27 + 51 + 12) = 35
Probability that none out of six chosen at random are Mechanical Engineering major :
Probability = required outcome / Total possible outcomes
Non mechanical engineering majors = 125 - 51 = 74
Probability none of 6 selected are mechanical engineering majors :
74C6 / 125C6
Recall :
nCr = n! / (n-r)! r!
, using calculator :
74C6 / 125C6 = 185250786 / 4690625500
= 0.0394938
= 0.039

[tex]\frac{4}{5}[/tex]
Step-by-step explanation:
Key skills needed --> Division of fractions, Multiplication of fractions
1) 2/4 over 5/8 is the same thing as division ---> [tex]\frac{2}{4}[/tex] ÷ [tex]\frac{5}{8}[/tex] = [tex]\frac{2}{4}[/tex] × [tex]\frac{8}{5}[/tex] = [tex]\frac{16}{20}[/tex] = [tex]\frac{4}{5}[/tex]
2) Dividing by a fraction is the same thing as multiplying by its reciprocal.
Basically if you are dividing by [tex]\frac{3}{4}[/tex], you are multiplying by [tex]\frac{4}{3}[/tex]. A reciprocal is when the fraction's numerator becomes the denominator, and the fraction's denominator becomes the numerator. [tex]\frac{1}{2}[/tex] --> reciprocal is [tex]\frac{2}{1}[/tex] (or 2)

The value of the expression [tex]log_b(4b) = 3.[/tex]
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
We can use logarithmic rules to solve this problem.
First, we know that log_b(8) = 3.
Using the definition of logarithms, this means that b³ = 8.
Solving for b, we find that b = 2.
Next, we know that log_b(0.5) = -1.
Using the definition of logarithms, this means that b^(-1) = 0.5.
Solving for b, we find that b = 2.
Since both expressions have the same base, we can use the logarithmic rule that states log_b(xy) = log_b(x) + log_b(y) to simplify log_b(4b) as follows:
[tex]log_b(4b) = log_b(4) + log_b(b)[/tex]
We can use the logarithmic rule that states:
log_b(b) = 1 to simplify log_b(b):
[tex]log_b(4b) = log_b(4) + 1[/tex]
Now, we can use the logarithmic rule that states:
[tex]log_b(x) = log_c(x)/log_c(b)[/tex]
To convert log_b(4) to a base 2 logarithm:
[tex]log_b(4) = log_2(4)/log_2(b) = 2/1 = 2[/tex]
Substituting this into the expression we found earlier, we get:
[tex]log_b(4b) = log_b(4) + 1 = 2 + 1 = 3[/tex]
Therefore,
[tex]log_b(4b) = 3.[/tex]

Use the equation 2m + 4s = 16 to complete the table, then graph the line using s as the
dependent variable.
Answer:
S. 4
M. 2
S. 5
M. 8
And the graphing you just do those as m/s -->(M,S)
You can put the value of m or s in the given equation of m and s to obtained the missing value.
The completed table would look like:
[tex]\begin{array}{ccccc}m & 0 & 2 & -2 & 8\\s & 4 & 3 & 5 & 0\end{array}[/tex]
Simplifying the relation between m and s:[tex]2m + 4s = 16\\\\ \text{Dividing by 2 on both sides}\\\\ \dfrac{2m + 4s}{2} = \dfrac{16}{2}\\\\ m + 2s = 8[/tex]
How to evaluate the missing values?Use one of the given value and the equation to find the missing value:
For m = 0:[tex]m + 2s = 8\\ 0 + 2s = 8\\ 2s = 8\\\\ s = \dfrac{8}{2}\\\\ s = 4[/tex]
For s = 3:[tex]m + 2s = 8\\ m + 2 \times 3 = 8\\ m = 8 - 6\\ m = 2[/tex]
For m = -2:[tex]m + 2s = 8\\ -2 + 2s = 8\\ 2s = 10\\ \\ s = \dfrac{10}{2} \\\\ s= 5[/tex]
For s= 0:[tex]m + 2s = 8\\ m + 2 \times 0 = 8\\ m = 8[/tex]
Thus, the completed table would be:
[tex]\begin{array}{ccccc}m & 0 & 2 & -2 & 8\\s & 4 & 3 & 5 & 0\end{array}[/tex]

Amount of tip = [tex]\frac{18}{100}*75[/tex]
Amount of tip = [tex]0.18 * 75[/tex]
Amount of tip = $13.50
