Select the table that represents a linear function. (Graph them if necessary.)
Answers
Answer:
table B represents the linear equation which is:
[tex]y=-3x+11[/tex]
The graph of the linear function is also attached below.
Step-by-step explanation:
Given the table B values
x y
0 11
1 8
2 5
3 2
As the equation for the linear function
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
As the y-intercept can be obtained by setting x=0
From the table, it is clear that when the value of x=0, then the value of
y=11.
so (0, 11) is the y-intercept.
Also taking two points (0, 11) and (1, 8) to find the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:11\right),\:\left(x_2,\:y_2\right)=\left(1,\:8\right)[/tex]
[tex]m=\frac{8-11}{1-0}[/tex]
[tex]m=-3[/tex]
so substituting the value m=-3 and the point (1, 8) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-8=-3\left(x-1\right)[/tex]
[tex]y-8=-3x+3[/tex]
[tex]y=-3x+3+8[/tex]
[tex]y=-3x+11[/tex]
comparing the equation with the slope-intercept form of linear equation
[tex]y=mx+b[/tex]
[tex]y=-3x+11[/tex]
here
m=slope=-3b=y-intercept=11Therefore, table B represents the linear equation which is:
[tex]y=-3x+11[/tex]
The graph of the linear function is also attached below.

B

An ice chest contains 7 cans of apple juice, 6 cans of grape juice, 6 cans of orange juice, and 4 cans of mango juice. Suppose that you reach into the container and randomly select three cans in succession. Find the probability of selecting three cans of mango juice.
Answers
Answer:
4/1771Step-by-step explanation:
Step one:
given
sample space
7 cans of apple juice,
6 cans of grape juice,
6 cans of orange juice, and
4 cans of mango juice
Sample size= (7+6+6+4)
= 23
Step two:
Required
The probability of randomly selecting three cans of mango juice in succession
Note: we are selecting without replacement
let the probability of selecting three cans of mango juice be
the first selection is= 4/23
The second = 3/22
the third= 2/21
[tex]P(x)= 4/23*3/22*2/21[/tex]
[tex]P(x)= \frac{4*3*2}{23*22*21} \\\\P(x)= \frac{4}{23*11*7}\\\\P(x)= \frac{4}{1771}[/tex]

Step-by-step explanation:
3*x = 3x
3*-4= -12
3x - 12 = 12x
12x-3x = 9x
9x-12
Answer: x = -4/3
Step-by-step explanation:
3(x−4)=12x
Step 1: Simplify both sides of the equation.
3(x−4)=12x
(3)(x)+(3)(−4)=12x (Distribute)
3x+−12=12x
3x−12=12x
Step 2: Subtract 12x from both sides.
3x−12−12x=12x−12x
−9x−12=0
Step 3: Add 12 to both sides.
−9x−12+12=0+12
−9x=12
Step 4: Divide both sides by -9.
-9x/-9 = 12/-9
x = -4/3

Answer:
x=9
Step-by-step explanation:
First you have to identify the black line at the bottom so it means it's 180 degrees. No notice the red box it means it's 90 degrees. We can conclude from this that the other side of the red box should also equal 90 degrees. So to find x you have to set up this equation: 6x+4+32=90. Then you solve for x which ends up being 9.
If you liked my answer then please make it the brainliest it would be much appreciated. Thanks!
Answer:
The x would be 9
Step-by-step explanation:
9 times 6 equals 54 plus 4 equals 58
the square is 90 degrees and 90 plus 58 plus 32 equals 180 degrees which is the right amount of a flat line

Step-by-step explanation:
A manufacturer wants to construct a box whose base length is 4 times the base width. The material to build the top and bottom cost 8 dollars per ft.2 and sides 5 dollars per ft.2. If the box must have a volume of 72 ft.3, determine the dimensions that will minimize cost.
Answers
Answer:
width = 1.77845 ft
length = 7.1138 ft
height = 5.691 ft
total cost = $759.09
Step-by-step explanation:
volume = length x width x height
length = 4 width
base of the rectangle = 4 x 1 w = 4w²
72 (volume) = 4w²h
18 = w²h
f(c) = (2 x 4w² x $10) + (2 x wh x $5) + (2 x 4wh x $5)
f(c) = 80w² + 10wh + 40wh
f(c) = 80w² + 50wh
since we need only 1 variable (width), we have to substitute h:
h = 18/w²
f(c) = 80w² + 50w(18/w²) = 80w² + 900/w
f'(c) = 160w + 900/w²
0 = (160w³ + 900)/w²
0 = 160w³ + 900
0 = 20(8w³ + 45)
0 = 8w³ + 45
8w³ = -45
w³ = -45/8
w = ∛-45/8 = -1.77845 and 1.77845
since w cannot be negative, then it must be 1.77845
