Answer:
(0,-2)
Step-by-step explanation:
First we find the equation of the line passes through [tex](-3,-5)[/tex] and [tex](7,5)[/tex].
The slope of the line is
[tex]m=\frac{5-(-5)}{7-(-3)}\\=\frac{10}{10}\\=1[/tex]
So by the point slope formula the equation of the line is
[tex]y-5=1(x-7)\\y=x-7+5\\y=x-2[/tex]
When [tex]x=0[/tex] we have [tex]y=0-2=-2[/tex].
Therefore the line joining the two points cuts the y-axis at (0,-2).
Tim has 74 socks, all in pairs. He has 1 more pair of white socks than black socks. How many individual socks of each color does he have?
The number of black and white socks Tim has is :
Black = 36Black = 36White = 38Let the Number of white and black socks be x and y respectively.
Hence, Total number of socks can be expressed Mathematically as :
x + y = 74 - - - (1)
Since, he has 1 pair (2) more white Than black socks ;then
Number of white socks = 1 + number of black socks
x = 2 + y - - - (2)
Therefore ;
2 + y + y = 74
2 + 2y = 74
2y = 74 - 2
2y = 72
y = 72 / 2
y = 36
x = 2 + y
x = 2 + 36
x = 38
Black socks = 36
Black socks = 36White socks = 38

Which of these is a factor in this expression?
5z4 – 3+8 (y + 4)
O A. (y + 4)
OB. 8 (73 + 4)
O C. 524 – 3
OD. -3+8 (+ 4)
Answer:
A. (y + 4)
Step-by-step explanation:
A factor means that it can be multiplied to a number or an expression to form exactly another expression or another number which are not fractions or decimals, they have no remainder. Looking for a factor, you need to see what is being multiplied. The brackets indicates what is being multiplied. Therefore (y + 4) is the factor since it is being multiplied to the number. Even the number
'524 - 3 + 8' is a factor
Further example to familiarize yourself can be
2 x 3 = 6
2 and 3 are both factors of 6. They are both being multiplied to form 6.

Is negative square root of nine a integer?
Find length
__
AB
A:-6
B: 8
To find the distance between those two points you would need to
do, -6 - (8), which is -14, and than take away the minus sign, and the length of AB is 14 units.
Answer:
14 = AB
Step-by-step explanation:
When finding length, absolute value is the way to go! So if A is -6 and b is 8, then we need to find the distance between them. You can physically count on a number line like I see you did, which would be -5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8=14 numbers
or you can set up the expression---
| -6-8 |
which equals
| -14 |
or
14
because 14 is the same as | -14 |

Lois makes customised tee-shirts. She advertises and receives orders through her own website. She buys blank tee-shirts for $1 each and $1 of fabric paint is used to produce the bespoke designs. She pays herself $6 per hour for her time to create the designs and package the teeshirts. In addition she makes a profit of 20% of the selling price. For how much will she sell a tee-shirt, if the artwork and packaging takes one and a half hours to complete?
Lois will sell her tee-shirt for $13.20
The percentage profit = [tex]\frac{profit}{cost price}[/tex] × 100
Profit = Selling price - cost price
Cost price is the total amount expended in making the tee-shirts
cost price includes cost of buying blank shirt , cost of fabric paint and amount Lois pay herself
cost of buying blank shirt = $1
cost of fabric paint = $1
amount Lois pay herself = [tex]1\frac{1}{2}[/tex] x $6
[tex]\frac{3}{2}[/tex] x $6 = $9
Total cost price = $1 + $1 + $9 = $11
0.2 = [tex]\frac{profit}{11}[/tex]
profit = 11 x 0.2 = $2.2
$2.20 = selling price - $11
selling price = $11 + 2.20 = $13.20

What is a Quadratic Function?The quadratic function can represent a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.
For solving a quadratic function you should find the discriminant: D=b²-4ac and after that use this variable in the formula: [tex]x=\frac{-b\pm \sqrt{D} }{2a}[/tex]
Properties of Multiplication
The properties of multiplication are:
Distributive: a(b±c)= ab±ac Comutative: a . b = b. a Associative: a(b+c)= c(a+b) Identity: b.1=bHere, you should apply the distributive property for solving this expression.
x*(2x)+2*(x+5) = 2x²+2x+10
After that, you should solve the previous quadratic equation.
D=b²-4ac=4-4*2*10=4-80= -76
Then,
[tex]x_{1,2}=\frac{-2\pm \sqrt{-76} }{2*2}=\frac{-2\pm i*\sqrt{76} }{4}=\frac{-2\pm i*2\sqrt{19} }{4}=\frac{-1\pm i*\sqrt{19} }{2}[/tex]

What are Similarities and differences between Inequality Notation, Set Builder Notation, and Interval Notation
Answer:
As the question states - it's just a different notation to express the same thing.
When you represent a set with set notation, you look for a characteristic that identifies the elements of your set. For example, if you want to describe the set of all number greater than
2
and less than
10
, you write
{
x
∈
R
∣
2
<
x
<
10
}
Which you read as "All the real number
x
(
x
∈
R
) such that (the symbol "|")
x
is between
2
and
10
(
2
<
x
<
10
)
On the other hand, if you want to represent the set with interval notation, you need to know the upper and lower bound of the set, or possibly the upper and lower bound of all the intervals that compose the set.
For example, if your set is composed by all the numbers smaller than
5
, or between
10
and
20
, or greater than
100
, you write the following union of intervals:
(
−
∞
,
5
)
∪
(
10
,
20
)
∪
(
100
,
∞
)
This same set can be written in set notation:
{
x
∈
R
∣
x
<
5
or
10
<
x
<
20
or
x
>
100
}
Finally, note that if the characterization of the set is rather complex, the set notation becomes preferable to the interval one, which would require a great number of intervals in the union. In some other cases, it could be literally impossible to write a set in interval notation, for example is you consider only irrational numbers, you write
{
x
∈
R
∣
x
∉
Q
}
but you can't write is as union of intervals.
See explanation below
Step-by-step explanation:
Imagine we have to express
[
a
,
b
]
in set notation
A
=
[
a
,
b
]
, then
A
=
{
x
∈
R
/
a
≤
x
≤
b
}
In this notation we define the characteristics of all
x
belonging to this set
A
…x must be greater or equal to a and simultaneously smaller or equal to b...
Interval notation is other way to say the same but assuming that
[
means the extreme a is IN the interval and
(
means extreme
a
is not.

AP Macroeconomics students were given an exam on a particular topic. Each week, they were tested with a comparable exam on the same topic and the average score for the class was measured. The function M (t) = 80 – 20log(t + 1) models the average score for the class after t weeks. How many weeks will it take for the average score of the class to equal 60?
A. 8 weeks
B. 9 weeks
C. 10 weeks
D. 11 weeks
The answer to the question how many weeks will it take for the average score of the class to equal 60 is B 9 weeks
Since the average score M (t) = 80 – 20log(t + 1) where t = number of weeks, we need to find the number of weeks it will take the average score to reach 60.
So, we find t when M(t) = 60.
So, M (t) = 80 – 20log(t + 1)
60 = 80 – 20log(t + 1)
Subtracting 80 from both sides, we have
60 - 80 = – 20log(t + 1)
-20 = -20log(t + 1)
Dividing both sides by -20, we have
-20/-20 = log(t + 1)
1 = log(t + 1)
Taking inverse logarithm of both sides, we have
10¹ = t + 1
10 = t + 1
Subtracting 1 from both sides, we have
t = 10 - 1
t = 9 weeks
So, the answer to the question how many weeks will it take for the average score of the class to equal 60 is B 9 weeks
