Look at the graph.
The graph shows a line through the points left parenthesis negative 1 comma negative 2 right parentheses and left parenthesis 2 commas 1 right parenthesis.
The slope of the line is _______.
A. positive
B. negative
C. zero
D. undefined
Answer:
the slope is POSITIVE (answer A)
Step-by-step explanation:
The line goes through: (-1, -2) and ( 2, 1)
Then the slope can be calculated as:
slope = (y2 - y1) / (x2 - x1)
in our case:
slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1
Therefore, the slope is POSITIVE (answer A)

Answer:
X= - 2
Step-by-step explanation:
-3 (5x+6) - 3x = 6-6x
Remove the parentheses
-15x-18-3x=6-6x
Collect the like terms
-18x-18=6-6x
Move the variable to the left-hand side and change its sign
18x+6x=6+18
Collect the like terms
-12x=24
Divide both sides
X=-2

A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle.
True or false??
Given:
The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."
To find:
Whether the given statement in true or false.
Solution:
Area of circle is
[tex]A=\pi r^2[/tex]
Where, r is the radius of the circle.
Let [tex]r_1[/tex] be the radius of the original circle. So, the area of the circle is
[tex]A_1=\pi (r_1)^2[/tex]
The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:
[tex]r_2=1.5r_1[/tex]
The area of the new circle is
[tex]A_2=\pi (r_2)^2[/tex]
[tex]A_2=\pi (1.5r_1)^2[/tex]
[tex]A_2=2.25\pi (r_1)^2[/tex]
[tex]A_2=2.25A_1[/tex]
The area of the new circle is 2.25 times the area of the original circle.
Therefore, the given statement is false.

In a college philosophy class during the fall semester, there were 323 students,42% of whom were male and the rest of whom were female. In the springsemester, the same number of females was in the class as in the fall, but there were only 298 total students in the class. In the spring, what percent of students were female?
A. 46%B. 58%C. 63%D. 92%
Using the percentage concept, it is found that the percentage of female students in the spring was of:
C. 63%
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
During the fall semester, 58% of 323 students were female, hence:
0.58 x 323 = 187.
Then, during the spring semester, the same amount out of 298, hence:
[tex]P = \frac{187}{298} \times 100\% = 63\%[/tex]

Multiply the polynomials. (x-3)(x^2+2x+1)
Answer:
[tex]x^{3} -x^{2} -5x-3[/tex]
Step-by-step explanation:
you use distributive property for this, or you can do the box method
distributive:
[tex]x(x^{2} +2x+1)-3(x^{2} +2x+1)[/tex] (you multiply the second equation by x-3)
then distribute, or multiply everything
[tex]x^{3} +2x^{2} +x-3x^{2} -6x-3[/tex]
then collect like terms

Which of the following equations best verifies the reasonableness of the solution for
log, 128 = x?
The equations best verifies the reasonableness of the solution will be log₃ 2187 = 7 and log₃ (3⁷) = 7. Then the correct options are A and E.
What is a logarithm?Exponents can also be written as logarithms. A number base logarithm is similar to some other number. It is the exact inverse of the exponent expression.
The equation is given below.
log₃ x = 7
Take anti-log on both side, then we have
x = 3⁷
x = 2187
Then the equation is satisfied by 2187. Then we have
log₃ 2187 = 7
log₃ (3⁷) = 7
Then the correct options are A and E.

Solve −3(7n+3)<6n. Write the solution using set-builder notation.
The set builder notation of the inequality - 3(7n + 3) < 6n is,
{n : n ∈ R, n > - 3 }.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, An inequality - 3(7n + 3) < 6n.
Now, distributing the terms we get,
- 21n - 9 < 6n.
- 21n - 6n < 9.
- 27n < 9.
27n > - 9. (Think of moving the variable to the other side to make it
