Given the table of values below, which of the following ordered pairs are
found on the graph of the inverse function?
х
-2
-1
0
1
2
f(x)
12
10
8
6
4
Answer:
(12,-2), (10,-1), (8,0), (6,1) and (4,2).
Step-by-step explanation:
If a function is defined as
[tex]f(x)=\{(x,y):x\in R,y\in R\}[/tex]
then its inverse is defined as
[tex]f^{-1}(x)=\{(y,x):x\in R,y\in R\}[/tex]
It means coordinates of ordered pairs are interchanged.
From the given table it is clear that the function passing through the points (-2,12), (-1,10), (0,8), (1,6) and (2,4).
Using the above definition, we can say that the inverse function passing through the points (12,-2), (10,-1), (8,0), (6,1) and (4,2).
Therefore, the required ordered pairs are (12,-2), (10,-1), (8,0), (6,1) and (4,2).
The shape has an area of 60 square inches. Find the value of x.
Answer:
5 inches
Step-by-step explanation:
A=bh
A=bx
60=12x
12x=60
x=5
Answer:
x = 5 In.
Step-by-step explanation:
The area of a parellelogram is usually basically the same as that of a rectangle or square. So the equation for the area of this parellogram is 60/12.
That would give you 5 which makes x equal to 5 inches.
-2/3a-6=12 what does a equal a=?
Answer:
a= -27
Step-by-step explanation:
The other answer I had was wrong so..
// have a great day //
Answer:
-2/3 a - 6 = 12
+6 +6
-2/3 a = 18
divide by -2/3 on both sides
a = -27.00027
Step-by-step explanation:
CHECK
-2/3 ( -27.00027) -6 = 12
18.00018 -6 = 12
12.00018 about 12 SO YES ITS CORRECT

Why can you use cross products to solve the proportion StartFraction 18 over 5 EndFraction = StartFraction x over 100 EndFraction for x?
because 18 times 100 is equal to 5 times x, which means that x is equal to 36
because 18 times 100 is equal to 5 times x, which means that x is equal to 360
because 18 times x is equal to 5 times 100, which means that x is equal to 36
because 18 times x is equal to 5 times 100, which means that x is equal to 360
Answer:
because 18 times 100 is equal to 5 times x, which means that x is equal to 360
Step-by-step explanation:
18/5=x/100
Cross product
18*100=5*x
1800=5x
x=1800/5
x=360
because 18 times 100 is equal to 5 times x, which means that x is equal to 360

Find the function that represents the relationship in the table
a)
y = 14x + 14
b)
y = 8x + 14
c)
y = 8x
d)
y = 14x + 8
Answer:
option B
Step-by-step explanation:
when the x value is multiplied by 8 and the result is added to 14 you will get the corresponding y value
A triangle is sitting on a horizontal line. The bottom left interior angle of the triangle is (9 + k) degrees. The exterior angle to the bottom left interior angle is (5 k minus 3) degrees.
What is the value of k?
k = 28
k = 29
k = 31
k = 42
Answer:
29
Step-by-step explanation:
If you mean the exterior angle at the same vertex as the interior,
(9+k)+(5k-3)=180
9+k+5k-3=180
6k+6=180
6k=174
k=29 degrees
Answer:
29

A typical dove weighs 345g. A typical duck weighs 1.2kg. What is the difference, in grams, of the weights of a duck and a dove?
Answer:
855 grams
Step-by-step explanation:
First convert the 1.2kg into grams.
1.2kg=1200 grams.
Now we have equal units of measurement. We then subtract: 1200g-345g=855g

How many times larger is 5 × 10 to the power of 6 than 5 × 10 to the power of 2?
Answer:
10,000
Step-by-step explanation:
The bases of the scientific notation are the same, so the answer must be a base of 10. So you just divide [tex]10^{6}[/tex] and [tex]10^{2}[/tex], you should get [tex]10^{4}[/tex], which is equal to 10,000.

The sum of three numbers is 16. The sum of twice the first number, 5 times the second number, and 6 times the third number is 85. The difference between 4 times the first number and the second number is negative 3. Find the three numbers.
Answer:
1, 7, 8Step-by-step explanation:
x, y, z - numbers to find
The difference between 4 times the first number and the second number is negative 3:
4x - y = -3
- y = -3 - 4x
y = 3 + 4x
The sum of three numbers is 16:
x + y + z = 16
x + 4x + 3 + z = 16
5x + z = 13
z = 13 - 5x
The sum of twice the first number, 5 times the second number, and 6 times the third number is 85:
2x + 5y + 6z = 85
2x + 5(3 + 4x) + 6(13-5x) = 85
2x + 15 + 20x + 78 - 30x = 85
-8x + 93 = 85
-8x = -8
x = 1
y = 3 + 4•1 = 7
z = 13 - 5•1 = 8
Veryfying:
1 + 7 + 8 = 16
2•1 + 5•7 + 6•8 = 2 + 35 + 48 = 85

question 3 <><><><><><><><><><><>
Answer: C. none of the above
Step-by-step explanation:
Because you are dealing with a positive and a negative number here, the only way you would be able to get a positive number out of both would be if you squared both of the numbers in parentheses. (grab a calculator and try it if you have one)
(6)^2 and (-6)^2 both give you 36.
And, 6)^3 and (-6)^3 both give you 216.
But, because there are no parentheses in the equation, then the answers would be different, so the correct answer is none of the above.

Find the value of x in the given figure using properties of parallel lines. answers : A) 27° B) 18° C) 36° D) 54°
Answer:
[tex]\mathrm{B}[/tex]
Step-by-step explanation:
[tex]126+3x=180[/tex]
[tex]3x=180-126[/tex]
[tex]3x=54[/tex]
[tex]\frac{3x}{3}=\frac{54}{3}[/tex]
[tex]x=18[/tex]
Answer:
[tex]x = 18[/tex]
Step-by-step explanation:
Co - interior angles = 180°
[tex]3x + 126 = 180 \\ 3x = 180 - 126 \\ 3x = 54 \\ \frac{3x}{3} = \frac{54}{3} \\ x = 18[/tex]

Y=4x + 6
Y = 6x - 12
Solve the systems of equation by substitution
Answer:
x=9, y=42
Step-by-step explanation:
y=4x+6
y=6x-12
Substitute the second equation into the first:
6x-12=4x+6
Subtract 4x from both sides:
2x-12=6
Add 12 to both sides:
2x=18
Divide both sides by 2:
x=9
Plug this back into one of the equations to find y:
y=4(9)+6=36+6=42
Hope this helps!

if it goes down 0.8 % every year it would be 1392
this is what I did 1,450−0.8%−0.8%−0.8%−0.8%
−0.8% I did -0.8% for every year i did 5 times for 5 years
so that the value but if u want the really accurate one then the answer is 1,392.9206056485 i hate myself for doing that but yeah thats it
Meg and Kevin wanted to solve this problem: In 6 hours, Hank the Hiker hiked 24 miles. At that rate, how far can he hike in 9 hours? Meg claimed she could solve the problem by finding Hank’s unit rate of speed in miles per hour. She began by writing the equation: . Explain whether or not she can find the unit rate this way. Then find the unit rate and use it to solve the problem. Show all your work.
Answer: Hank hike 36 miles in 9 h.
6 hours for 24 miles
9 hours for x miles
[tex]Hank_{rate} =24/6=4\;mi/h[/tex]
[tex]x = Hank_{rate}\times Hours=4\;\frac{mi}{h} \times 9\;mi=36 \;miles[/tex]
