Write the equation of a line that is perpendicular to the given line and that passes through the given point y+ 2 = -(x - 5). (4.3) Oy=-3x+15 Oy=-3x - 9 Oy=-4x + 3 Oy=-x-11 =-
Answers
Answer:
B. y = -3x - 9
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
The equation perpendicular to the given equation is y=-3x-9. Therefore, option B is the correct answer.
Given that, the equation of the line is y+2 = 1/3 (x-5) and the coordinate point is (-4, 3).
Here, the slope is 1/3
The slope of a line perpendicular to given line is m1=-1/m2
So, the slope is m=-3
Substitute m=-3 and (x, y)=(-4, 3) in y=mx+c, we get
3=-3×(-4)+c
3=12+c
c=-9
So, the equation is y=-3x-9
Therefore, option B is the correct answer.

I really need help! How would I solve this? 4(x−6)−3=2(3−2x)−5
Answers
Remember distributing just means multiplying.
So it would be,
4 times x and 4 times -6
That would equal
4x-24-3=2(3-2x)-5
Now the other side. For this side we distribute the 2 since there is a 2 outside of the parenthesis.
That would equal
2 times 3 and 2 times 2x
Which is 6-4x
We put this whole equation together so it would be
4x-24-3=6-4x-5
We combine the like terms so in this case it would be
4x-28=1-4x
Now here notice how I only added the numbers without x. This is because they were like terms meaning I could add, subtract or multiply, or divide them, but however the number with x are not like terms so therefore we cannot add, subtract, multiply or divide them.
Now we can bring the variables to one side in this case I will bring it to the left side.
So that would be adding 4x to the left side.
So that would be
8x-28=1
Notice how I added the 4x to the 4x I did this because they were like terms.
After this we can now add 28 to both sides.
So that would be 8x=29
Now we divided 8 on both sides so it would be
x=29/8
Or if we simplifies it could be
x=7/2 or x=3.5 or x= 3 1/2

Domain:
Range:
Answers
Answer:
Domain → (-∞, ∞)
Range → (-∞, ∞)
Step-by-step explanation:
Domain of a function is defined by the x-values or input values of the graph.
Similarly, Range of the function is defined by the y-values or output values from the graph.
From the picture attached,
x - values for the line shown in the graph vary from negative infinity to positive infinity.
Therefore, Domain of the function will be → (-∞, ∞)
And for every x-value there is a y-value, so Range of the function will be same as domain (varying from negative infinity to positive infinity) → (-∞, ∞)

The scale drawing of a porch is 8 inches wide by 12 inches long. If the actual porch is 12 feet wide, find the length of the porch. (Draw and label polygons then solve.)
Answers
Answer: The length of porch is 18 feet.
Step-by-step explanation:
Given: The scale drawing of a porch is 8 inches wide by 12 inches long.
The actual porch is 12 feet wide.
Actual porch and the drawing are similar, then
[tex]\dfrac{\text{Actual length}}{\text{Actual width}}=\dfrac{\text{ length in drawing}}{\text{Width in drawing}}[/tex]
[tex]\Rightarrow\ \dfrac{\text{Actual length}}{12}=\dfrac{12}{8}\\\\\Rightarrow\ \text{Actual length}= \dfrac{12}{8}\times12\\\\\Rightarrow\ \text{Actual length}= 18[/tex]
Hence, the length of porch is 18 feet.
Given that the corresponding sides of similar shapes are proportional, the length of the porch would be calculated as: 18 inches.
What are Similar Shapes?Shapes that are similar have corresponding sides that are proportional to each other.
Thus:
Length of scale drawing = 12 inchesActual length of porch = xWidth of scale drawing = 8 inchesActual width of porch = 12 ftTherefore:
x/12 = 12/8
Cross multiply
8x = (12)(12)
x = 18 inches.
Therefore, given that the corresponding sides of similar shapes are proportional, the length of the porch would be calculated as: 18 inches.

The image of the point (1, -3)(1,−3) under a translation is (-4, -2)(−4,−2). Find the coordinates of the image of the point (-3, 7)(−3,7) under the same translation.
Answers
Answer:
The new points under the translation are (-8,8) and (-8,8)
Step-by-step explanation:
The method is actually quite simple and only involves basic arithmetic. The first step is to identify the translations occurring to each coordinate. If we recall that an ordered pair is (x,y), we can assign the translations to each value. Let's take the first point (1, -3) to start. 1 is our x and -3 is our y. If we then look at the translated point we can see that the x value there is -4. Then we can simply subtract the new x value, -4, from the first one, 1, and get 5. 5 is the number that we have to subtract from the next coordinate set to get the translated set. This gets us the first value of the second point -8 which we got by subtracting our 5 from the -3 in the x. Next, we can do the y value. The process is identical. Subtract the new from the old, -3-(-2)=-1. We then simply subtract the negative one (or just add one) from the y value of the other set. This gives us a value of 8, 7-(-1)=8. Then compound the two together putting x first then y and there you have it! Happy to help, Mw

A store sells almonds for $8 per pound and peanuts for $14 per pound. A customer paid $31.50 for a 3-pound mixture of
aimonds and peanuts. The system of equations can be used to represent this situation.
x + y = 3
8x + 14y
31.5
Part A
What does the variable x represent in this system of equations?
Answers
Answer:
The number of pounds of almonds the customer purchased
Step-by-step explanation:
The system of equations can be used to represent this situation is as follows:
x + y = 3
8x + 14y = 31.50
The variable x represents the amount in pound of peanuts.
The almond cost $8 per pound and peanuts cost $14 per pound.
Therefore,
let
x = amount in pounds of almond
y = amount in pounds of peanuts
The customer bought a total of 3 pound. Therefore,
Total weight in pounds:x + y = 3The customer paid a total of $31.50 for the 3 pounds mixture. Therefore,
Total cost :8x + 14y = 31.50Therefore, the variable x represents the amount in pound of peanuts.

Answer:
27 days.
Step-by-step explanation:
Find 1% out of the 30-day period.
100% = 30 days
1% = 30 ÷ 100 = 0.30
Now find the percentage reported that had measurable snowfall which is 90%.
90% = 0.30 x 90 = 27
Out of the 30-day period, only 27 days received measurable snow.

Fourteen of the people signed up for the ski classes are beginners. If 56% of those signed up are beginners, how many people signed up for classes?
Answers
Answer:
25
Step-by-step explanation:
An unknown number of people signed up for the class. Let the total number of people who signed up be x.
56% of the people who signed up are beginners. 14 people are beginners.
That means that
56% of the people who signed up is 14 people.
56% of x = 14
56% * x = 14
0.56x = 14
Divide both sides by 0.56.
0.56x/0.56 = 14/0.56
x = 25
