Using linear functions, the system of inequalities that matches the graph is given by:
y ≥ 3x.y > -2x - 1.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points, the slope is given by change in y divided by change in x. For the first line, the points are:
(-1, -3) and (0,0).
Hence the slope is:
m = (0 - (-3))/(0 - (-1))
m = 3.
When x = 0, y = 0, hence the y-intercept is of b = 0 and the line is given by:
y = 3x.
Everything to the right of the solid line is shaded, hence the values that are equal(line is solid) or greater than the line compose the inequality, as follows:
y ≥ 3x.
For the second line, the points are:
(-2,3) and (1,-3).
Hence the slope is:
m = (-3 - 3)/(1 - (-2)) = -6/3 = -2.
Then:
y = -2x + b.
When x = -2, y = 3, hence:
3 = -2(-2) + b
b = -1.
Hence the line is:
y = -2x - 1.
Everything to the right of the dashed line is shaded, hence the inequality is:
y > -2x - 1.

PUNTOS Write the equation of the line parallel to y = -1/3x + 4 and passing through the point (-6, -9). Be sure to write your answer in slope-intercept form(y=mx+b)
The slope intercept of the line is y = -1/3x -11
Slope-intercept is one of the special forms of line equation
The slope intercept of a line can be found by solving the slope-intercept equation of a line which is parallel to that line.
Slope-intercept equation is
y = mx + b
where m is the slope and b is the intercept.
The slope-intercept equation of the parallel line is
y = -1/3x + 4
The slope will be the same for both lines as they were parallel to each other.
Thus m = -1/3
The point in which the line passes is given as (-6,-9)
So with these data, We can find the intercept of the line
y = mx + b
where m = -1/3 and (x,y) is (-6,-9),Thus
-9 = -1/3(-6) +b
-9 = 6/3 +b
-9 = 2 + b
b = -9-2
b = -11
Thus the intercept of the line passing through the point (-6,-9) is -11
Thus, the slope-intercept equation of the line we need to find is
y = -1/3x -11

Answer:
[tex]-\sqrt{2}[/tex]
Step-by-step explanation:
Note that:
[tex]a^2-2ab+b^2=(a-b)^2 = 4ab \\ \\ a^2 + 2ab+b^2 = (a+b)^2 = 8ab \\ \\ \implies \frac{a+b}{a-b}=\frac{\sqrt{8ab}}{-\sqrt{4ab}}=-\sqrt{2}[/tex]
Answer:
[tex]\sf \dfrac{a+b}{a-b}= -\sqrt{2}[/tex]
Step-by-step explanation:
[tex]\sf a^2 + b^2 = 6ab \qquad where\:\:0 < a < b[/tex]
Basic formula:
[tex]\sf (a + b)^2 = a^2 +b^2 +2ab[/tex]
[tex]\sf (a - b)^2 = a^2 + b^2 -2ab[/tex]
solve for a + b
[tex]\sf \rightarrow a^2 + b^2 = 6ab[/tex]
[tex]\sf \rightarrow (a+b)^2-2ab = 6ab[/tex]
[tex]\sf \rightarrow (a+b)^2 = 6ab+2ab[/tex]
[tex]\sf \rightarrow (a+b)^2 = 8ab[/tex]
[tex]\sf \rightarrow a+b = \pm \sqrt{8ab}[/tex]
solve for a - b
[tex]\sf \rightarrow a^2 + b^2 = 6ab[/tex]
[tex]\sf \rightarrow (a-b)^2 + 2ab = 6ab[/tex]
[tex]\sf \rightarrow (a-b)^2 = 6ab-2ab[/tex]
[tex]\sf \rightarrow (a-b)^2 = 4ab[/tex]
[tex]\sf \rightarrow a-b = \pm \sqrt{4ab}[/tex]
Now solve for (a + b)/(a - b)
[tex]\sf \rightarrow \dfrac{a+b}{a-b}= \dfrac{\pm\sqrt{8ab} }{\pm\sqrt{4ab} }[/tex]
[tex]\sf \rightarrow \dfrac{a+b}{a-b}= \pm \sqrt\dfrac{8ab }{4ab}[/tex]
[tex]\sf \rightarrow \dfrac{a+b}{a-b}= \pm \sqrt{2}[/tex]
As, the value of b is greater than the value of a and both the values a and b are greater than 0. It turns the value of expression negative as the denominator will be always evaluated to negative integer and the numerator value always > 0. So, the answer will be negative, -√2.
[tex]\sf \rightarrow \dfrac{a+b}{a-b}= - \sqrt{2}[/tex]

What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
The dark city had a population of 350,000 in 1990 and has increased exponentially since then, to 475,000 in 2008. Then the equation will be
350,000 = a(b) ...1
475,000 = a(b)¹⁸ ...2
From equations 1 and 2, then we have
475,000 / 350,000 = b¹⁷
b = 1.018
Then the value of the variable a will be
350,000 = 1.018a
a = 343768.87
Then the equation will be
y = 343,768.87 (1.018)ˣ
The population in 2015 will be
y = 343,768.87 (1.018)¹⁵
y = 343,768.87 x 1.3068
y = 449,245

The african bush elephant weights about 4.4 tons and 7.7 tons what are if least and greatest sight rounded to the nearest ton
The least ton is 4 ton and the greatest ton is 8 ton.
Given an approximation for the weight of African bush elephant.
If we take x as the weight of an African Bush elephant, then
4.4 < x < 7.7.
We are asked to find the least and greatest weights rounded to the nearest ton.
The least weight is 4.4. But when rounded to the nearest ton, we can consider the least weight at 4 tons.
Likewise, the greatest weight is 7.7 tons.
But the greatest weight rounded to the nearest ton = 8 tons
We rounded 4.4 to 4 because the decimal digit 4 is less than 5.
Also we rounded 7.7 to 8 because the decimal digit 7 is greater than 5.

(second digit in the answer!) e) quicksilver collected 700 nickels in a jar. he went to the bank to cash them in. how much money did the bank give him? f) for breakfast, mystique bought a bagel for $1.55 and a glass of orange juice for $2.25. at lunch, mystique spent $6.25 on a sandwich and $0.55 on a carton of milk. how much more money did she spend on lunch than on breakfast? g) mirage had three pizzas. each pizza had eight slices. if mirage at 75% of the pizza slices, how many were left? h) iceman has a highlighter obsession. in his desk drawer, there are 19 yellow highlighters. there are 15 more blue highlighters than yellow, and there are 37 green highlighters total. how many more green highlighters than blue does he have?
He finished the number of books by the time he arrived = 3.3 books, b) she withdrew $15 from her bank account. c) 6 people have nothing on their feet.d) He must wait before he can buy the pair of shoes = 20 minutes. e) After dividing the bank gives him 700 nickels = $35. f) She spent more money on lunch than breakfast = $3. g) After eating the mirage slices left = 6 slices. h) He has more green highlighter than blue = 3
a) professor finished 3 books by the time he arrived.
Professor x traveled to see jean grey = 1500 miles
He read one book he traveled = 450 miles
So,
He finished books by the time he arrived by dividing both the numbers = 1500/450
He finished total books by the time he arrived = 3.3 books
b) Storm had money = $74
She bought a pair of slacks = $34
She bought two shirts = $16
She bought a pair of shoes = $24
After shopping she left with = $15
Storm expenses on the items = $34 + $16 + $24
= $74
So, after shopping she left with $15 so it is clear that she withdrew $15 from her bank account.
c) Pacific northwest geocachers in wolverine’s living room = 12
Wearing shoes = 4
Wearing socks = 6
Wearing both socks and shoes = 4
As we know 4people wearing both socks and shoes
So, 2 people are wearing only sock
And no people wearing only shoes = 4-4=0
So, in total 4+2+0= 6
Now, 12 people are there
So, 12-6=6
So, 6 people have nothing on their feet.
d) Cyclops waited 20 minutes
Cyclops will buy a new pair of shoes = 1200 seconds
Here, 60 minutes = 3600 seconds
Now, divide 1200 seconds by a minute (1 minute = 60 sec)
He must wait before he can buy the pair of shoes = 1200/60
He must wait before he can buy the pair of shoes = 20 minutes
e) Quicksilver collected nickels in a jar = 700
First, we have to calculate how many cents are there in 700 nickels by multiplying 700 * 5, and then dividing that result by 100 cents
=700 nickels x 5 cents
= 3,500 cents ( 100 cents = $1)
= 3,500 cents / 100 cents
The bank gives him 700 nickels = $35
f) For breakfast, Mystique bought a bagel = $1.55
A glass of orange juice = $2.25
At lunch,
On sandwich, she spent = $6.25
On a carton of milk, she spent = $0.55
Total spent on breakfast = $1.55+$2.25
= $3.80
Total spent on lunch = $6.25+$0.55
= $6.80
She spent more money on lunch than breakfast = $6.80-$3.80
She spent more money on lunch than breakfast = $3
g) Mirage had 3 pizzas
Each pizza had = 8 slices
So, After multiplying total number of slice we have of the pizza = 3*8
= 24 slices
He ate 75% of the pizza slices = 75/100 * 24
= ¾ * 24
After multiplying, he ate pizza slice = 3 * 6
= 18 slices
So, after eating by the mirage slices left = 24-18
= 6 slices
h) He has 3 more green highlighters than blue highlighters.
In the iceman desk drawer, the number of yellow highlighters are = 19
As given, there are 15 more blue highlighters than yellow in his desk drawer
Then,
the number of blue highlighters = 19+15
= 34
There are total numbers of green highlighters = 37
He has more green highlighters than blue highlighters = 37-34
= 3

in 5 miles. Which measurement is closest to the number of kilometers between these
two lighthouses?
Measurement is closest to the number of kilometers between these
two lighthouses is 219.2 kilometers.
Assume the distance between two lighthouses is x kilometers in 137 miles.
It knows there are approximately 8 kilometer in 5 miles.
Since the number of kilometers per mile is same
So x:137=8:5
x/137=8/5
5x=1096
5x/5=1096/5
x=219.2
1 kilometer is equal to 0.621371 miles (often shortened to . 62). 1 mile is equal to 1.609344 kilometers. Thus, to convert kilometers to miles, simply multiply the number of kilometers by 0.62137.
