Give a non-zero counterexample to the following statement:
Every multiple of 10 is also a multiple of 30.
Answer:
20 or 40 or 50
(there are many others)
Step-by-step explanation:
A counterexample is an example that shows the statement is not true. The statement in this question is that if a number is a multiple of 10 (10, 20, 30, 40, 50, 60...) then it is a multiple of 30. Some numbers are, like 60 and 90, but not all numbers. So for example (counterexample) 20 is a multiple of 10 but NOT a multiple of 30.
40 is a multiple of 10, but NOT a multople of 30.
50 is a multiple of 10, but NOT a multiple of 30.

Answer:
38%
Step-by-step explanation:
Total: 93
Find percentage
Rain: 24
Snow: 11
24 + 11 = 35
Find what percentage of 90 35 is.
35 of 90 can be written as:
35
----
90
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100
35 100
---- × ----
90 100
= ( 35 * 100/90) * 1/100 = 38.89/100

Is (2,11) a solution to the equation y = 3x - 2 ?
Answer:
No (2, 11) is not a solution.
Step-by-step explanation:
y = 3x - 2
Plug in the points:
11 = 3(2) - 2
Solve:
11 = 6 - 2
11 = 4
11 does not equal 4.

What is the location of the image of P(−8, 1) after a counterclockwise rotation of 90° about (−2, 6) ?
Answer:
(3, 0)
Step-by-step explanation:
Given:
Image: P = (-8, 1)Center of rotation: (-2, 6)Rotation rule for -90°: (x, y) → (y, -x)
As the center of rotation is not the origin, we cannot simply apply the above rule.
To rotate an image around a point other than the origin:
1. Subtract each point of the image from the point of rotation:
⇒ Point of rotation - point of image
⇒ (-2, 6) - P = (-2, 6) - (-8, 1)
= (6, 5)
2. Rotate this about the origin by applying the rotation rule:
⇒ (x, y) → (y, -x)
⇒ (6, 5) → (5, -6)
Add the point of rotation to each rotated point of the image:
⇒ (5, -6) + (-2, 6) = (3, 0)
Therefore, the location of the image of P (-8, 1) after a counterclockwise rotation of 90° about (-2, 6) is (3, 0).
Write the equation of the line that passes through the points (4, -3) and (-5, 4).
Put your answer in fully simplified point-slope form, unless it is a vertical or
horizontal line.
Answer:
y₁ - y₂ = (-7/9)(x₁ - x₂)
Step-by-step explanation:
The general structure for an equation in point-slope form is:
y₁ - y₂ = m(x₁ - x₂)
In this form, "m" represents the slope and the "x" and "y" values come from each point. To find "m", plug the values of each point into the equation.
Point 1: (4, -3) Point 2: (-5,4)
y₁ - y₂ = m(x₁ - x₂) <---- Original equation
-3 - 4 = m(4 - (-5)) <---- Plug values in for "x" and "y"
-7 = m(4 - (-5)) <---- Simplify left side
-7 = m(9) <---- Simplify within parentheses
-7/9 = m <---- Divide both sides by 9
I don't exactly understand what "fully simplified point-slope form" means because if all of the variables are plugged in, you wouldn't be left with an equation. It may just be asking for the slope, which in this case would make the equation look like this:
y₁ - y₂ = (-7/9)(x₁ - x₂)
It may want you to find the equation in slope-intercept form (y = mx + b), and you would have to find "b". Sorry I don't quite understand what exactly you are looking for.

Complete questionAt a certain college, 49% of the students are female, and 21% of the students major in civil engineering. Furthermore, 8% of the students both are female and major in civil engineering. What is the probability that a randomly selected female student majors in civil engineering?
How to determine the probability?Let A represent Female and B represents civil engineering.
The above representation means that the given parameters are:
P(A) = 49%P(B) = 21%P(A and B) = 8%The required probability is calculated as:
P(A or B) = P(A) + P(B) - P(A and B)
This gives
P(A or B) = 49% + 21% - 8%
Evaluate
P(A or B) = 62%
Hence, the probability that a student is a female or major in civil engineering is 62%

The functions f(x) and g(x) are shown on the graph.
The image shows two graphs. The first is f of x equals log base 3 of x and it is increasing from negative infinity in quadrant four as it goes along the y-axis and passes through 0 comma 1 to turn and increase to the right to positive infinity. The second is g of x and it is increasing from negative infinity in quadrant two as it goes along x equals negative 4 and passes through 0 comma negative 3 to turn and increase to the right to positive infinity.
Using f(x), what is the equation that represents g(x)?
g(x) = log3(x) – 4
g(x) = log3(x) + 4
g(x) = log3(x – 4)
g(x) = log3(x + 4)
Answer:
[tex]g(x)=\log_3(x+4)[/tex]
Step-by-step explanation:
Translations
For [tex]a > 0[/tex]
[tex]f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}[/tex]
[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]
[tex]f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}[/tex]
[tex]f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}[/tex]
Parent function:
[tex]f(x)=\log_3x[/tex]
From inspection of the graph:
The x-intercept of [tex]f(x)[/tex] is (1, 0)The x-intercept of [tex]g(x)[/tex] is (-3, 0)If there was a vertical translation, the end behaviors of both g(x) and f(x) would be the same in that the both functions would be increasing from -∞ in quadrant IV.
As the x-intercepts of both functions is different, and g(x) increases from -∞ in quadrant III, this indicates that there has been a horizontal translation of 4 units to the left.
Therefore:
[tex]g(x)=f(x+4)=\log_3(x+4)[/tex]
Further Proof
Logs of zero or negative numbers are undefined.
From inspection of the graph, [tex]x=-3[/tex] is part of the domain of g(x).
Therefore, input this value of x into the answer options:
[tex]g(-3)=\log_3(-3)-4\implies[/tex] undefined
[tex]g(-3)=\log_3(-3)+4\implies[/tex] undefined
[tex]g(-3)=\log_3(-3-4)=\log_3(-7)=\implies[/tex] undefined
[tex]g(-3)=\log_3(-3+4)=\log_3(1)=0[/tex]
Hence proving that [tex]g(x)=\log_3(x+4)[/tex]
The equation that represents g(x) is: [tex]g(x) = log_3(x + 4)[/tex]
The correct answer is: the fourth option:
[tex]g(x) = log_3(x + 4)[/tex].
Here, we have to find the equation that represents g(x) using f(x), we need to consider how the graph of g(x) is related to the graph of f(x).
The graph of f(x) = log base 3 of x starts from negative infinity in quadrant four, passes through (0, 1), and increases to positive infinity.
The graph of g(x) is increasing from negative infinity in quadrant two, passes through (0, -3), and increases to positive infinity.
So, we can see that the graph of g(x) is the graph of f(x) shifted 4 units to the left along the x-axis.
Therefore, the equation that represents g(x) is:
[tex]g(x) = log_3(x + 4)[/tex]
The correct answer is: the fourth option:
[tex]g(x) = log_3(x + 4)[/tex].
