what is the equation linethatis perpendicular to the given line and passes through the point (3,0)?
Answer:
3y+x = 3
Step-by-step explanation:
for the point ( 3,0)
x=3 , y= 0
the equation for the line is given as
y-y1= m(x-x1)
for perpendicular ,
m= -1/x
so
y-0 = -1/3(x-3)
3y= -x +3
3y+x=3
Answer: 5x - 3y = 15
Step-by-step explanation: was correct on edge test.

Answer:
In order from smallest to largest:
g(x)=(1,-2)
now, f(x) and h(x) would reach the same height, so from left to right on the graph, if plotting all vertices:
h(x)=(-2,2)
f(x)=(4,2)
Step-by-step explanation:
f(x)
f(x)=-2(x-4)^2+2
This is the vertex form of a quadratic equation: The formula used is f(x)=a(x-h)^2+k, where (h,k) is the vertex. In this case, 4 is h and 2 is k, so the vertex of this equation is (4,2).
g(x)
g(x)=5x^2-10x+7
To find the vertex of a quadratic equation in standard form, you first have to find the x-coordinate of the vertex using the formula, -b/2a. In this equation, a=5 and b=-10, so plug into the formula: -(-10)/2(5)=10/10=1, so the x-coordinate of the vertex is 1. Now to find the y-coordinate of the vertex by plugging in the x-coodinate for x in the equation: 5(1)^2-10(1)+7=5(1)-10+7=5-10+7=-5+7=-2, so your y-coordinate is -2. Therefore, your vertex for this equation is (1,-2).
h(x)
So, this quadratic function is in the form of a graph. The vertex of the graph is the maximum of minimum value of the graph, depending on whether the graph is positive or negative. In this graph, it is the maximum point, which is (-2,2).
A pair of shoes cost $120 but they are 25% Off;
What would be discount and the final price of those
shoes?
Answer:
Discount = $30, Final price = $90
Step-by-step explanation:
25% is one quarter. 120/4=30
One quarter of 120 is 30, so - 30 would give discounted price of $90.
Similarly you could think of it like the discounted price is 75% of the original one and do 120x0.75=90 to find 75% of 120.
Hope this helped!

The function h(x) = 12x8 + 49 is an even function. Which transformation of h(x) would result in a function that is neither even nor odd? reflection over the x-axis vertical stretch by a factor of 7 translation 8 units to the right horizontal compression by a factor ofOne-half
Answer: translation 8 units to the right
Step-by-step explanation:
An even function is a function such that:
h(x) = h(-x)
and the function is odd if:
h(-x) = -h(x)
Now, let's talk about transformations:
A) Reflection over the x-axis:
When we have a point (x,y) and we do a reflection over the x-axis, the reflected point will be:
(x, -y).
Then for the case of a function:
y = h(x).
then the reflection will be:
g(x) = - y = -h(x).
And if h(x) is even, -h(x) is also even, so this is not the correct option.
B) Vertical stretch by a factor of 7.
This is written as:
g(x) = 7*h(x).
then:
g(x) = 7*h(x)
g(-x) = 7*h(-x) = 7*h(x) = g(x)
the transformation is even.
C) Translation of 8 units to the right.
We can write this as:
g(x) = h(x - 8).
Then:
g(-x) = h(-x -8) = h(x + 8)
Then g(-x) is not equal to g(x)
and also g(-x) ≠ -g(x)
So in this case the transformation is neither odd or even.
C) horizontal compression by a factor of One-half.
This transformation is written as:
g(x) = h( (1/2)*x)
And, similar as the case of the vertical compression, in this case the transformation is also even.
Answer: C
Step-by-step explanation:
Translation 8 units to the right

The 8 students in Mrs. Allen's class were asked how many minutes it takes them to get to school in the morning. Here is what they answered: 4, 12, 9, 6, 3, 15, 15, 6 Find the mean and median travel times for these students. If necessary, round your answers to the nearest tenth.
Answer:
Mean: 8,75
Median: 7,5
Step-by-step explanation:
To find Mean
To find the mean data you have to put data all set in order:
3, 4, 6, 6, 9, 12, 15, 15
Then, all of the numbers in the data set added together and then divided by how many numbers in the data that already put in order:
3 + 4 + 6 + 6 + 9 + 12 + 15 + 15 = 70
There are 8 numbers in the data so divide 70 by 8:
70 ÷ 8 = 8,75
----
To find Median
The median is in the middle number of the data that already in order. Which is number 6 and 9.
Median = (6 + 9) ÷ 2
Median = 15 : 2
Median = 7,5

-x^2 -8=-33 Enter the solutions from least to greatest.
Answer:
x = -5, 5
Step-by-step explanation:
Step 1: Write out equation
-x² - 8 = -33
Step 2: Add 8 on both sides
-x² = -25
Step 3: Divide both sides by -1
x² = 25
Step 4: Take square root on both sides
x = ±5
Step 5: Arrange
-5 < 5
So x = -5, 5

11. An AC waveform has a peak voltage of 50 VAC. What's the
waveform's RMS voltage?
O A. 50.0 VAC
B. 35.4 VAC
C. 24.8 VAC
O D.52.8 VAC
Answer:
Option B - 35.4 VAC
Step-by-step explanation:
Formula for peak voltage is;
V_p = V_rms × √2
Making V_rms the formula, we have;
V_rms = (V_p)/√2
We are given:Peak voltage: V_p = 50 VAC
Where 50 VAC means 50 Volts AC power
Thus;
V_rms = 50/√2
V_rms ≈ 35.4 VAC
So option B is correct
A rectangle is a 6 2/3 feet long and 3 1/5 feet wide. About how many feet is the distance around the rectangle
Answer:
[tex]\frac{296}{15}[/tex] or [tex]19\frac{11}{15}[/tex]
Step-by-step explanation:
The distance around the rectangle is also known as the perimeter of the rectangle.
The formula for the perimeter of a rectangle is 2l+2w.
The width of this rectangle is 3 1/5 feet and the length of this rectangle is 6 2/3 feet, so plug into the perimeter formula:
P=2l+2w
=2(6 2/3)+2(3 1/5)
=2(20/3)+2(16/5)
=40/3+32/5
--(LCD is 15)
= 5/5(40/3)+3/3(32/5)
=200/15+96/15
=296/15 or 19 11/15 feet
The distance around the rectangle is about [tex]\frac{296}{15}[/tex] or [tex]19\frac{11}{15}[/tex].
Elena drank 3 liters of water yesterday. Jada drank 3/4 times as much water as Elena. Lin drank twice as much water as Jada. A. Did Jada drink more or less water than Elena? 1 point
Answer:
A. Jada drank less water than Elena
B. Lin drank more water than Elena
Step-by-step explanation:
Elena drink 3 Liters of water yesterday Jada drank 3/4 times as much water as Elena. Lin drank twice as much water as Jada.
A. Did Jada drink more or less water than Elena?
B. Did Lin drink more or less water than Elena?
Elena drank 3 liters of water
Jada drank 3/4 times as much water as Elena.
Lin drank twice as much water as Jada
Elena = 3 liters
Jada = 3/4 × Elena
=3/4 × 3
=9/4 liters
=2 1/4 liters
=2.25 liters
Lin=2×Jada
=2×9/4
=18/4
=4 2/4
=4.5 liters
Did Jada drink more or less water than Elena?
A. Jada drank less water than Elena
Because 2.25 liters is less than 3 liters
B. Lin drank more water than Elena
4.5 liters is greater than 3 liters

Mr Jones is 4 years older than his wife and 31 years older than his son. their ages add up to 82 years. if Mr Jones is x years old, find the value of x and the ages of his wife and son.
first person here gets the brainiest award thingy!
Answer:
39 Mr Jones
35 Mrs. Jones
8 Son
Step-by-step explanation:
x ----> Mr. Jones
x - 4 ----> His wife
x - 31 ---> His son
x + (x - 4) + (x - 31) = 82
3x - 35 = 82
3x = 82 + 35
3x = 117
x = 117/3
x = 39 Mr Jones
x - 4
39 - 4
35 Mrs. Jones
x - 31
39 - 31

A die is thrown . find the probability of (1) a multiple of 2 or 3
Answer:
A die is thrown which means that it can land on either 1-6 on the die.So if you want to find the probability of the multiple of 2 or 3....we have multiplies of 2 in the die from 1-6 which is 2,4 and 6 if you count them they are just 3 numbers and since there is a probability of it to land on any of them it will be 3/6 which is 1/2 if yiu divide by 3 to it's lowest term....Then multiple of 3 is 3,and 6.which will be 2/6 which is 1/3 if u cut to its lowest term. Or in the question means addition sign in probability then it is 2 or 3 which is (1/2)+(1/3)=5/6.Thank you for the question

a+b/c=5. Solve for b
Answer:
b = c(5 - a)
Step-by-step explanation:
Given
a + [tex]\frac{b}{c}[/tex] = 5 ( subtract a from both sides )
[tex]\frac{b}{c}[/tex] = 5 - a ( multiply both sides by c to clear the fraction )
b = c(5 - a)
The value of b form the equation a + b/c = 5 will be b = c(5 - a)
How to evaluate a given mathematical expression with variables if values of the variables are known?We can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
Given;
a + b/c = 5
subtract a from both sides;
b/c = 5 - a
multiply both sides by c to clear the fraction;
b = c(5 - a)
Hence, The value of b form the equation a + b/c = 5 will be b = c(5 - a)

y = 4800(1.239)
growth or decay
Hello there! :D
Well, it is a general rule of thumb that growth is indicated by positive numbers, and decay is indicated by negative numbers. I would show decay in this exponential equation by making the percentage inside the parenthesis negative. It would look like this: y=4800(-1.239)
Obviously, this equation does not have a negative integer so we know it must constitue growth!
