What is the equation of a line that is perpendicular to the line y=2x+1 and passes through the point (4,6)?
Answer:
y = - [tex]\frac{1}{2}[/tex] x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 1 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (4, 6 ) into the partial equation
6 = - 2 + c ⇒ c = 6 + 2 = 8
y = - [tex]\frac{1}{2}[/tex] x + 8 ← equation of line

Answer:
3 recipes/week
Step-by-step explanation:
Pick any two points where the line passes to a point in the grid, so you don't go crazy with counts. That means (0.0) (1;3) (2;6) (3;9) Pick two of them, in order. Let's say we like (0.0) and (1.3) since we're lazy. Now let's subtract the second part of each pair, (in our case, 0-3), do it for the first pair (in our case 0-1) and divide the two results: [tex]{-3 \over -1} = 3[/tex] Feel free to pick any other two and double check, being careful you're always doing [tex]\Delta y \over \Delta x[/tex]
For which function is the ordered pair (5, 10) not a solution?
y = 15 - x
y = x - 5
y = x + 5
y = 2 x
Answer:
y = x - 5
Step-by-step explanation:
y = x - 5
10 = 5 - 5
10 is not equal 0
Answer:
y = x - 5
Step-by-step explanation:
y = x - 5
10 = 5 - 5
10 is not equal 0
Allie says that the expressions 4x - 2x +4 and 2(x + 2) are not equivalent because one expression
has a term that is subtracted and the other does not. Do you agree? Explain.
Yes,
the expressions are equivalent. The first expression, 4x - 2x +4, can be simplified to
which equals 2(x + 2).
(Use the operation symbols in the math palette as needed.)
Answer:
the espression are equivalent
Step-by-step explanation:
4x - 2x + 4 = 2 (x + 2)
2x + 4 = 2x + 4
the espression are equivalent
Question 3 "Try Again." Mary needs 3 feet of boondoggle for a craft project.
Boondoggle costs $0.25 per inch. How much will the project cost Mary?
Answer:
$9.00
Step-by-step explanation:
We can use conversion factors to solve this equation. The multiplication sequence that I got is shown below:
[tex]\frac{3ft}{1}[/tex] × [tex]\frac{12 in}{1ft}[/tex] × [tex]\frac{0.25}{1in}[/tex]
Our feet and inches cancel out and we get the final expression [tex]\frac{3*12*0.25}{1}[/tex], which is equal to 9, or $9.00.
Hopefully that was helpful! :)

93 A carpenter has two different boards
measuring 80 inches and 64 inches. If the
carpenter cuts them into equally sized
pieces and has no wood left over, have long
will each piece be?
Answer:
Each piece will be 8 inches
Step-by-step explanation:
We have to find the HCF / GCF of 80 and 64
80 = 2 * 2 * 2 * 2 * 5
64 = 2 * 2 * 2 * 2 * 2 * 2
HCF = 2 *2 *2 = 8
80 inches = 8 * 10 . So, 10 boards each measuring 8 inches
64 = 8 * 8 . So, 8 boards each measuring 8 inches
(81)¾ - (27)⅓
\3 × 2³
Answer:
I won't tell you the answer but if you read the solution, you would understand it.
Step-by-step explanation:
81^3/4 is basically 3 times the fourth root of 81. What number multiplies 4 times to make 81? Then multiply that by 3.
Now we have the cube root of 27. If you have a fractional exponent with no numerator, that just means square root, cube root, fourth root.
Eg. the exponent 1/4 would just mean fourth root
Eg. The exponent 1/2 would just mean square root
The cube root of 27 is 3.
The denominator is 3 times 2 to the third power.
PEMDAS
Order of Operations tells us we do exponents first so 2 to the third power is 8 and multiply by that 3.
You have all the information you need. Now just use your arithmetic skills! Let me know if you need more help.

If given 5 miles is 8km convert 13.5 miles into km
Step-by-step explanation:
There are 2 ways we can do this. We can use our friend which we will call a special device or we could actually solve using formulas we already know. Today, I will be using a formula but you can easily just use the secret device.
Step 1: Knowing the formula which is multiply miles by 1.609 and then round to the nearest tenth or hundredth.
13.5 X 1.609 = 21.7215.
Round down to 21.7.
Final Answer: 21.7 Km is equal to 13.5 miles or vice versa.
Carson has a smart phone data plan that costs $35 per month that includes 10 GB of data, but will charge an extra $15 per GB over the included amount. How much would Carson have to pay in a month where he used 3 GB over the limit? How much would Carson have to pay in a month where he used went over by xx GB?
Total cost when over by 3 GB:
Total cost when over by xx GB:
Answer:
3 GB over: $80 x GB over: $35+$15x
Step-by-step explanation:
First, 3 GB over is 3 times 15 plus 35, which equals 80. x GB over is x times 15 plus 35, hence the answer. Hope this helps!

Answers in Explanation
Step-by-step explanation:
First Question:
[tex]\sqrt{100}[/tex] + [18 ÷ 3 x 4 - 15] - (60 - 7^2 - 1)
[tex]\sqrt{100}[/tex] + [24 - 15] - (60 - 49 - 1)
[tex]\sqrt{100}[/tex] + 9 - 10
10 + 9 - 10
Answer = 9
Second Question:
5x + 2x = 7x
5x^2 + 3x^2 = 8x^2
2x + 3x - x = 4x
2x + 3y + x + y = 3x + 4y
9x - 6x = 3x
-7y + 3x + 4x + 3y = 7x - 4y
-7x^2 + 2x^2 + 9x^2 = 8x^2
(3x^2 + 5x + 4) - (-1 + x^2) = 2x^2 + 5x + 5
(3 + 2x - x^2) + (x^2 + 8x + 5) = 10x + 8
(3x - 4) - (5x + 2) = -2x - 6
(2x^2 + 5x + 3) - (x^2 - 2x + 3) = x^2 + 7x
(3x^2 + 2x - 5) - (2x^2 - x - 4) = x^2 + 3x - 1
Third Question:
17x + 2y
(5x + 12y) + (3x + y) = 8x + 13y
17x - 8x = 9x
2y - 13y = -11y
Answer: 9x - 11y

Answer:
0.01085 ~ 1.085%
Step-by-step explanation:
Okay so a simple way to do these probability ones is to add an extra space around each side
YES NO
POSITIVE 325 2 _____
NEGATIVE 16 1131 _____
_____ _____ _____
Now in these spaces add all the the rows and columns accordingly
YES NO
POSITIVE 325 2 _327_
NEGATIVE 16 1131 _1147_
_341_ _1133_ _1474_
Now the number in the place where the additional rows meet is your total number of patients, so this is what you would use for your probability.
So we are looking for YES / NEGATIVE which is 16
Now do 16 divided by 1474 and your probability comes out to 0.01085..., so as a percentage, would be 1.085%
Hope that helped :)

What is the ratio of the number of beaks to the number of legs the chickens and the sheep have on this farm?
Answer: 1:9
Step-by-step explanation:
If you multiply 2 legs times 8 chickens we get 16
If you multiply 4 legs times 14 sheep we get 56
The number of legs is 16+56=72
So you have 8 beaks and 72 legs or 8:72
Divide both sides by 8 to simplify and you get 1:9 as the answer

Answer:
x= 1 and y =1
Step-by-step explanation:
4+4 is 8, therefore for this to be true both must be 1
Answer:
x = 1; y = 1
Step-by-step explanation:
We know x and y have to equal the same thing because 4 + 4 = 8
x = 4 / 4
y = 4 / 4
x = 1
y = 1
Therefore, x = 1; y = 1
