Which inequality matches the graph?
A) x > -2
B) x < -2
C) x = -2
D) x ≤ -2
Answer:
D) x ≤ -2
Step-by-step explanation:
The dot is at -2 = -2
the dot is filled in = ≤ or ≥ because its means equal too
think of ≤ or ≥ like arrows = it points left.
so its x ≤ -2
Note on using the ≤ or ≥ like pointing arrows
this only works if its written:
variable < constant form,
which is the way they are usually seen, like x < 5
but it could be 5 > x which means the > points the opposite way

There is a geometric theorem that says "If twp lines in a plane are perpendicular to the same line, they are parallel to each other." Explain why this is true by writing and comparing equations for two different lines that are perpendicular to y= -1/3x.
Two lines perpendicular to a third line are parallel to each other because they both inherit the slope from their perpendicularity. The resulting lines only differ in their y-intercepts, indicating they run parallel.
Explanation:The theorem you're referring to essentially relates to the slope of the lines. If two lines are each perpendicular to the same line, this means the slope of all three lines are related. This occurs because the slope of any line perpendicular to y=-1/3x is 3, the negative reciprocal of -1/3. For example, if we have two lines L1: y = 3x + b1 and L2: y = 3x + b2 which are both perpendicular to y= -1/3x (and thus parallel to each other), their formulas would only differ by their y-intercepts (b1 and b2). Since the coefficient of x (the slope) remains the same (3), we can conclude that these two lines are indeed parallel to each other which confirms the mentioned geometric theorem.

a man pays 20% of his salary as tax and has 24,000$ left. How much did he pay as tax
Answer:
He paid $6,000 in taxes.
Step-by-step explanation:
His final amount after taxes is $24000. In order to obtain this number we had to tax 20% of the total (Note that 100%-20%=80%). In other words if he was taxed 20% he took home 80% of what he was paid. Therefore mathematically we have:
[tex]0.8A_{pre-tax}=A_{taxed}[/tex]
Since we know he was left with $24000 after taxes then:
[tex]0.8A_{pre-tax}=24000\\\\\frac{0.8A_{pre-tax}}{0.8}=\frac{24000}{0.8}\\\\A_{pre-tax}=\frac{24000}{0.8}\\\\A_{pre-tax}=30000[/tex]
So originally he had $30,000. So how much did he pay in taxes? We can calculate the difference of both pretax and after tax and we get:
$30,000 - $24,000= $6,000 taxed
A jacket costs $35 and has an 8 percent tax rate. Which expression will find the cost of the tax on the jacket
Answer:
Step-by-step explanation:
35 x .08 = $2.80
35 + 2.80 = 37.80
Answer:
T = 0.08 × 35
Step-by-step explanation:
The cost of a jacket = $35
The tax rate on the jacket = 8% = [tex]\frac{8}{100}[/tex]
= 0.08
The expression to find the cost of the tax on the jacket would be
T = 0.08 × 35
the expression 1.2p represents the total bill given to a pizza delivery man if he is given a tip of 20% and p represents the cost of the pizza. is this true expression?
Answer: The statement is false because 1.2 is calculating 120% of the cost of pizza. The expression should be .2p.
Step-by-step explanation:
The expression 1.2p correctly represents the total bill for a pizza including a 20% tip, with p representing the price of the pizza. To determine the total cost, you multiply the price by 1.20.
The expression 1.2p does indeed represent the total bill including a 20% tip for the delivery of a pizza where p is the cost of the pizza. When you give a tip of 20%, you are adding 20% of the cost of the pizza to the original price. This is calculated by multiplying the price by 1.20 (which is equivalent to 100% + 20%).
Example Calculation:
If the cost of the pizza is $10 (p = $10), then the total bill with a tip would be 1.2 × $10 = $12. The 20% tip on $10 is $2, so the total bill equals $10 + $2 = $12.

3/4( 1/6 x+16)= 3/7 (4 3/8 x−21)
Answer:
x=12
Step-by-step explanation:
Solve for x:
(3 (x/6 + 16))/4 = (3 ((4 + 3/8) x - 21))/7
Put 4 + 3/8 over the common denominator 8. 4 + 3/8 = (8×4)/8 + 3/8:
(3 (x/6 + 16))/4 = (3 ((8×4)/8 + 3/8 x - 21))/7
8×4 = 32:
(3 (x/6 + 16))/4 = (3 ((32/8 + 3/8) x - 21))/7
32/8 + 3/8 = (32 + 3)/8:
(3 (x/6 + 16))/4 = (3 ((32 + 3)/8 x - 21))/7
32 + 3 = 35:
(3 (x/6 + 16))/4 = (3 ((35 x)/8 - 21))/7
Put each term in x/6 + 16 over the common denominator 6: x/6 + 16 = x/6 + 96/6:
3/4 x/6 + 96/6 = (3 ((35 x)/8 - 21))/7
x/6 + 96/6 = (x + 96)/6:
3/4 (x + 96)/6 = (3 ((35 x)/8 - 21))/7
3/6 = 3/(3×2) = 1/2:
(x + 96)/(2×4) = (3 ((35 x)/8 - 21))/7
Put each term in (35 x)/8 - 21 over the common denominator 8: (35 x)/8 - 21 = (35 x)/8 - 168/8:
(x + 96)/(2×4) = 3/7 (35 x)/8 - 168/8
(35 x)/8 - 168/8 = (35 x - 168)/8:
(x + 96)/(2×4) = 3/7 (35 x - 168)/8
2×4 = 8:
(x + 96)/8 = (3 (35 x - 168))/(8×7)
8×7 = 56:
(x + 96)/8 = (3 (35 x - 168))/56
Multiply both sides by 56:
(56 (x + 96))/8 = (56×3 (35 x - 168))/56
56/8 = (8×7)/8 = 7:
7 (x + 96) = (56×3 (35 x - 168))/56
(56×3 (35 x - 168))/56 = 56/56×3 (35 x - 168) = 3 (35 x - 168):
7 (x + 96) = 3 (35 x - 168)
Expand out terms of the left hand side:
7 x + 672 = 3 (35 x - 168)
Expand out terms of the right hand side:
7 x + 672 = 105 x - 504
Subtract 105 x from both sides:
(7 x - 105 x) + 672 = (105 x - 105 x) - 504
7 x - 105 x = -98 x:
-98 x + 672 = (105 x - 105 x) - 504
105 x - 105 x = 0:
672 - 98 x = -504
Subtract 672 from both sides:
(672 - 672) - 98 x = -672 - 504
672 - 672 = 0:
-98 x = -672 - 504
-672 - 504 = -1176:
-98 x = -1176
Divide both sides of -98 x = -1176 by -98:
(-98 x)/(-98) = (-1176)/(-98)
(-98)/(-98) = 1:
x = (-1176)/(-98)
The gcd of -1176 and -98 is -98, so (-1176)/(-98) = (-98×12)/(-98×1) = (-98)/(-98)×12 = 12:
Answer: x = 12

Answer:
y-2 = 2/3(x-8)
Step-by-step explanation:
We have the line 6x-9y = -7
Let's rewrite it in the form y=mx+b
6x-9y = -7
Subtract 6x from each side
6x-6x-9y = -7 -6x
-9y = -6x-7
Divide by -9
-9y/-9 = -6x/-9 -7/-9
y = 2/3 x + 7/9
The slope is 2/3
If the line is parallel, the slope will be the same so the slope will be 2/3
We have the slope and a point (8,2) on the new line, so we can use the point slope form of a line
y-y1 = m(x-x1)
y-2 = 2/3(x-8)

5|-6+r|=55
[tex]5 | - 6 + r| = 55[/tex]
Answer:
r= -5 , r= 17
Step-by-step explanation:
5|-6+r|=55
solve for 'r'
First we isolate absolute function
We divide both sides by 5
|-6+r| = 11
for absolute function we consider two cases, one with positive and one with negative. Now we make two equations
-6+r = 11 or -6+r = -11
Now solve both equations
-6 + r= 11
Add 6 on both sides
so , r= 17
-6 + r= -11
add 6 on both sides , so r= -5
Two boats sail away from a buoy making a 90 degree angle. The first boat is 165 meters away and is traveling at 25 m/s. The second boat has been traveling at 35 m/s for pi mINUTES. What is the rate of change in distance between the two boats?
Answer:
Step-by-step explanation:
lets say in the shown triangle x=165
so speed [tex]\frac{dx}{dt} =25[/tex]
and [tex]\frac{dy}{dt} =35[/tex]
Also since distance = speed* time
time = pi minutes = pi/60 seconds
y = [tex]\frac{35\pi \pi }{60}[/tex]
y = [tex]\frac{7\pi }{12}[/tex]
Now using the pythagorean :
[tex]x^2+y^2=z^2\\so \\165^2+(\frac{7\pi }{12} )^2 =z^2[/tex]
derivate the equation so we get :
[tex]x\frac{dx}{dt} +y\frac{dy}{dt} =z\frac{dz}{dt} \\[/tex][tex]165*25+35*\frac{7\pi }{12}=\sqrt{165^2+(\frac{7\pi }{12})^2} *\frac{dz}{dt}[/tex]
[tex]\frac{dz}{dt} =25.387[/tex] m/s
So Rate of change = 25.387 m/s

Arithmetic, Geometric, or Neither Classify each sequence as arithmetic, geometric, or neither. (matching) 4/9, 4/3, 4, 12, 36. 0, 1, 2, 3, 4, 5, 6. -10, -6, -2, 2, 6, 10.
Answer:
The given sequence is neither arithmetic not geometric.
Step-by-step explanation:
A sequence is in arithmetic if it has a common difference.
i.e., a sequence a, b, c is in arithmetic if
b - a = c - b
Let's check if the given sequence is in arithmetic.
[tex]\frac{4}{3} -\frac{4}{9} =\frac{12}{9} -\frac{4}{9}[/tex]
[tex]= \frac{8}{9}[/tex]
[tex]4-\frac{4}{3} =\frac{12-4}{3}[/tex]
[tex]=\frac{8}{3}[/tex]
So, [tex]\frac{4}{3} -\frac{4}{9} \neq 4-\frac{4}{3}[/tex]
Hence, the given sequence is not arithmetic.
Let's check if the given sequence is in geometric.
A sequence is in geometric if it has a common ratio.
i.e., a sequence a, b, c is in geometric if
[tex]\frac{b}{a} =\frac{c}{b}[/tex]
[tex]\frac{4/3}{4/9} =\frac{4}{3} (\frac{9}{4} )[/tex]
= 3
[tex]\frac{4}{4/3} =4(\frac{3}{4} )[/tex]
= 3
Clearly, [tex]\frac{12}{4} =\frac{36}{12} =3[/tex]
But, [tex]\frac{0}{36} =0[/tex]
Therefore, the given sequence is not in geometric.
Hence, the given sequence is neither arithmetic not geometric.

Which relation is a function?
Answer:
B
Step-by-step explanation:
For a relationship to be a function
Each value of x in the domain can only have 1 unique value of y in the range. That is, one-to-one correspondence.
The only relation which meets this criteria is B
Answer:
The answer is option B: {(1,3);(-1,5);(2,7);(-2,7);(3,5);(-3,3)}
Step-by-step explanation:
Each element is composed of a first and second point, or by an 'x' and 'y' coordinates, respectively. In this way, all x coordinate from the set of elements constitute the 'domain', and all y coordinates of the set of elements constitute the 'image'.
So, for a set of elements be a function, each point of the domain have to have one an only one image. In other words, two elements with the same image have to have a distinct x's coordinate.
If we take a look at the set of elements in the different options, we find different elements which repeat image:
1) The pairs (1,0) and (1,-1) in the set of point of option A
2) The pairs (-2,-1) and (-2,-2) in the set of point of option C
3) The pairs (1,3) and (1,3) in the set of point of option
In the set of elements of B option, all the elements with the same y coordinate have different x's coordinates.
