Answers
Answer:
Check the explanation.
Step-by-step explanation:
The slope-intercept form of the equation is
[tex]y=mx + b[/tex]
where m is the slopeb is the y-interceptLine A:
[tex]y = 1 2 x + 2[/tex]
The slope of line A:
[tex]m_A=12[/tex] ∵ comparing with [tex]y=mx + b[/tex]
Line B:
[tex]y = -1 2 x + 7[/tex]
[tex]m_B=-12[/tex] ∵ comparing with [tex]y=mx + b[/tex]
Line C:
[tex]y = -2x + 4[/tex]
[tex]m_C=-2[/tex] ∵ comparing with [tex]y=mx + b[/tex]
Line D:
[tex]y = 12x + 5 4[/tex]
[tex]m_D=12[/tex] ∵ comparing with [tex]y=mx + b[/tex]
As we know that the product of the slopes of perpendicular lines is -1.
i.e. their slopes are opposite of the reciprocal of each other.
Now, let us check the OPTIONS:
Option A) A and B
Check:
[tex]m_A=12[/tex]
[tex]m_B=-12[/tex]
As the product of the slopes A and B is NOT -1, so the lines A and B are not perpendicular. Hence, option A is NOT true.
Option B) A and C
[tex]m_A=12[/tex]
[tex]m_C=-2[/tex]
As the product of the slopes A and C is NOT -1, so the lines A and C are not perpendicular. Hence, option B is NOT true.
Option C) B and C
[tex]m_B=-12[/tex]
[tex]m_C=-2[/tex]
As the product of the slopes B and C is NOT -1, so the lines B and C are not perpendicular. Hence, option C is NOT true.
Option D) A and D
[tex]m_A=12[/tex]
[tex]m_D=12[/tex]
As the product of the slopes A and D is NOT -1, so the lines A and D are not perpendicular. Hence, option D is NOT true.
Therefore, NO OPTION is correct.

Solve for C. Show all work please.
C= 5/9 ( F - 32)
Answers
Answer:
Step-by-step explanation:
It is solved for C unless you C = 5/9 * F - 32*5/9
C = 5/9F - 17.8
=================
If you mean F, then Multiply both sides by 9/5
9/5 * C = F - 32
9/5 * C + 32 = F
=====================
A quick way to do this is to multiply by 2 and add 32
F = 2*C + 30
My wife, an American, always had to do this when she heard the daily temperatures in Canada.
first multiply both sides by 9/5 to get:
9/5C= F -32
Add 32 to both sides and transpose to get:
F=9/5C + 32
these are the formulas to translate between Fahrenheit and Celsius temperatures
Fahrenheit and Celsius meet at - 40 degrees
that is - 40 Fahrenheit = - 40 Celsius
So alternitive formulas for the conversations can be written:
F=9/5 (C+40) - 40
C=5/9 (F+40) - 40
Miguel's cat, Chester, weighs 6.8 pounds. Chester's vet tells Miguel to feed the cat 3 4 of an ounce of canned food daily for each pound of body weight. The next morning, Miguel opens a new can of food to feed Chester. If the can holds 5.5 ounces, how much food will be left after one day? Write your answer as a whole number, decimal, fraction, or mixed number. Simplify any fractions.
Answers
Answer:
0.4 ounces
Step-by-step explanation:
In a day
Miguel is to feed Chester ,
Chester can eat 3/4 of an ounce for each pound of body weight.
Chester weighs 6.8 pounds
Hence:
1 pound = 3/4 ounce
6.8 pounds = x ounces
Cross Multiply
x = 6.8 × (3/4) ounces
x = 5.1 ounces
Chester is to be fed 5.1 ounces of food each day.
The amount of food left after 1 day
= 5.5 ounces - 5.1 ounces
= 0.4 ounces
Hence, 0.4 ounces of food is left after 1 day

B. 1,500.00 miles
C. 142.86 miles
D. 1,750.00 miles
Answers
Answer:
b
Step-by-step explanation:
The distance is 1,750.0 miles if a Boeing 737 airplane travels about 500 miles per hour option (D) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The function d(t) = 500t represents the number of miles traveled in t hours.
Plug t = 3.5 hours in the equation of the function.
d(3.5) = 500(3.5)
d(3.5) = 1,750.0 miles
Thus, the distance is 1,750.0 miles if a Boeing 737 airplane travels about 500 miles per hour option (D) is correct.

He prime factorization of a number is 2 cubed times 3 squared times 5. Which is a true statement about the factors of the number? Fifteen is a factor of the number because both 3 and 5 are prime factors. Fifteen is not a factor of the number because 15 is odd and the number is even. Sixteen is a factor for the number because 2 cubed = 8 and 16 is divisible by 8. Sixteen is not a factor of the number because the exponent of 2 is not even.
Answers
Answer:
Fifteen is a factor of the number because both 3 and 5 are prime factors.
Step-by-step explanation:
The computation is shown below:
The cube of 2 is
= 2^3
= 8
The square of 3 is
= 3^2
= 9
Now if we multiplied the 3 digits that it would be
= 8 × 9 × 5
= 360
As we know that the 15 is a factor of 360
Therefore the first option is correct
i.e.
Fifteen is a factor of the number because both 3 and 5 are prime factors.
And all the other options are incorrect

D.Find the 11th term when the first term is -3 and the common difference is 4.
Answers
9514 1404 393
Answer:
all of them, possibly excepting the 4th term
Step-by-step explanation:
The recursive formula is good if you have terms near the one of interest. It might be used for the 4th term, but that would require that you compute the three previous terms:
7, 5, 3, 1 . . . . requires 3 subtractions
It can be about as easy to calculate ...
a4 = 7 -2(3) = 1 . . . . requires two* subtractions and a multiplication
__
However, for the 7th, 11th, and 106th terms, it is impractical to list all previous terms. The explicit formula is a better choice.
A. a4 = 7 -2(3) = 1
B. a7 = -1 +10(6) = 59
C. a106 = 2 +5(105) = 527
D. a11 = -3 +4(10) = 37
_____
* The explicit formula is ...
an = a1 +d(n -1)
The operations identified in this formula (in the order required by the Order of Operations) are subtraction, multiplication, and addition. For a negative common difference, that amounts to two subtractions and a multiplication.
For manual evaluation, the work involved in using the recursive or explicit formulas for the 4th term is about the same, if the arithmetic is easily done mentally (as here).

Answer:

Step-by-step explanation:
Given that mean absolute deviation tells you how to spread out or how clustered around the mean a set of data is.
Hence, in a comparison of sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean.
On the other hand, a lower mean absolute deviation indicates that the data points are nearer to the mean than a data set with a higher mean absolute deviation

Courtney is twice as old as Andre and three years older than Natalie. Courtney is half Shari's age. The difference between Shari's age and Natalie's age is the same as the sum of Courtney's age and Andre's age. The equation below represents their ages.
Answers
The question does not seem complete, but I'll represent the statement mathematically and look for their ages each. This is because the worst they can ask for is their ages.
Let C stand for Courtney's age, A for Andrei's age, N for Natalie's age and S for Shari's age. From the question we can deduce the following:
C = 2A
C = N + 3
C = S/2
S - N = C + A
S = 2C, N = C - 3 and A = C/2, therefore we have
2C - (C - 3) = C + C/2
C + 3 = C + C/2
C/2 = 3 and C = 6
A = C/2
A= 6/2
A = 3
N = C - 3
N = 6 - 3
N = 3
S = 2C
S = 2 x 6
S = 12.
C = 6, A = 3, N = 3 and S = 12

Given:
The set of points.
To find:
Which set of points represents a function?
Solution:
A set of points represents a function if there exist a unique y-value for each x-value.
It option A, the set of points is
{(1,-2), (3,-5), (3,-2), (5,-7), (7, -8)}
This is not a function because there exist two y-values y=-5 and y=-2 for x=3.
It option B, the set of points is
{(0,1),(1,−3),(2,−5),(3,−7),(4,−9)}
This is a function because there exist a unique y-value for each x-value.
It option C, the set of points is
{(−1,1),(−1,3),(−1,5),(−1,7),(−1,9)}
This is not a function because there exist five y-values y=1,3,5,7,9 for x=-1.
It option D, the set of points is
{(−4,0),(−3,−1),(−3,1),(0,−2),(0,2)}
This is not a function because there exist two y-values y=-1 and y=1 for x=-3.
Therefore, the correct option is B.

Sally is making bouquets of flowers with the ratio of red to white flowers being 2:3. If Sally used 12 red flowers, how many white flowers will she use?
Answers
Answer:
18 white flowers
Step-by-step explanation:
We are given ratio:
Red : White
2 : 3
If Sally used 12 red flowers, how many white flowers will she use?
Let the number of white flowers Sally uses be represented by x
This is calculated as:
2/3 = 12/x
Cross Multiply
2 × x = 3 × 12
x = 3 × 12/2
x = 18 white flowers
Therefore, if Sally used 12 red flowers, the number of white flowers will she use is 18 white flowers.
