cancelStep-by-step explanation:
10) there are infinity values for k
4(k-8)=-32+4k
4k-32=-32+4k
these two equal each other so any value is equal to k
12) there are no values for b
-(3-6b)=6b+5
-3+6b=6b+5
the b's out and you are left with -3=5 which is impossible
Hope that helps :)

What is the solution to the system of linear equations represented by the table?
Everything is in the picture
Answers
Answer:
B. (-3, -4)
Step-by-step explanation:
The solution to the system of the linear equations represented by the table is the coordinate pair of the point at which both the value of y1 and y2 are the same for a given x-value.
Thus, when x = -3, y1 and y2 are both -4.
Therefore, it is safe to conclude that the solution to the system of equations is:
(-3, -4).

elnumero e s 1Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 2 inches, and the larger gear has a radius of 7 inches.
Part 1: What is the angle measure, in degrees and rounded to the nearest tenth, through which the larger gear has rotated when the smaller gear has made one complete rotation?
Part 2: How many rotations will the smaller gear make during one complete rotation of the larger gear?
Show all work.
Answers
Answer:
Let r represent the radius of the smaller circle and R the radius of the larger circle.
Apply ratios: the radius of smaller circle to radius of larger circle, i.e.
r: R = 3 : 7.
I complete rotation = 360 degrees.
Part 1:
For one complete rotation of the smaller circle, the larger circle is rotated through: (3/7)*(360) = 154.3 degrees
Part 2:
For one complete rotation of the larger circle, the larger circle is rotated through: (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios:
The number of rotations = R/r = 7/3 = 2.3 rotations

for larger gear
l=4π
θ=l/r
θ=(4 ×180)/7=720/7=102 .9°
for larger gear circumference=2π×7=14π
number of rotations=(14π)/4π=7/2=3.5 rotations or 3 1/2 rotations.
Rewrite the function by completing the square.
f(x) = x^2 – 10x—96
Answers
Answer:
(x - 5)² -121 = 0
Step-by-step explanation:
if you need to find the roots you can take the square root of each side:
(x-5)² = 121
(x-5)² = 121
square root of (x-5)² is x-5
square root of 121 is ±11
first root: x-5 = 11
x = 16
second root: x-5 = -11
x = -6
Answer:
[tex]f(x) = (x - 5)^{2} - 121[/tex].
Step-by-step explanation:
The goal is to rewrite [tex]f(x)[/tex] in the vertex form [tex]a\, (x - h)^{2} + k[/tex] by completing the square (where [tex]a[/tex], [tex]h[/tex], and [tex]k[/tex] are constants.)
Expand the vertex form expression:
[tex]\begin{aligned}& a\, (x - h)^{2} + k\\ &= a\, (x - h)\, (x - h) + k \\ &= a\, \left(x^2 - h\, x - h\, x + h^2\right) + k \\ &= a\, \left(x^2 - 2\, h\, x + h^2\right) + k\\ &= a\, x^2 - 2\, a\, h\, x + \left(a\, h^2 + k\right) \end{aligned}[/tex].
Compare this expression to [tex]f(x) = x^2 - 10\, x - 96[/tex] and solve for the constants [tex]a[/tex], [tex]h[/tex], and [tex]k[/tex]. Make sure that the coefficient of each term matches:
Coefficient for the [tex]x^2[/tex] term: [tex]a[/tex] in the expanded expression and [tex]1[/tex] in the expression for [tex]f(x)[/tex]. Hence, [tex]a = 1[/tex].Coefficient for the [tex]x[/tex] term: [tex](-2\, a\, h)[/tex] in the expanded expression and [tex](-10)[/tex] in the expression for [tex]f(x)[/tex]. Hence, [tex]-2\, a\, h = -10[/tex].Coefficient for the constant term: [tex]\left(a\, h^2 + k\right)[/tex] in the expanded expression and [tex](-96)[/tex] in the expression for [tex]f(x)[/tex]. Hence, [tex]a\, h^{2} + k = -96[/tex].Substitute [tex]a = 1[/tex] into the second equation, [tex]-2\, a\, h = -10[/tex], and solve for [tex]h[/tex].
[tex]-2 \, h = -10[/tex].
[tex]h = 5[/tex].
Substitute both [tex]a = 1[/tex] and [tex]h = 5[/tex] into the third equation, [tex]a\, h^{2} + k = -96[/tex], and solve for [tex]k[/tex].
[tex]5^2 + k = -96[/tex].
[tex]k = -121[/tex].
Therefore, [tex]a\, (x - h)^{2} + k[/tex] becomes [tex](x - 5)^2 + (-121)[/tex].
Hence, the vertex form of the parabola [tex]f(x)[/tex] would be:
[tex]f(x) = (x - 5)^{2} - 121[/tex].

The total cost of a tablet device comprises the cost of material, labour and overheads in the ratio 3:4:1. The cost of material is $315. What is the total cost of the tablet?
Answers
Answer:
$840
Step-by-step explanation:
Given data
The cost of material is $315
The ratio is
3:4:1
The total number of part is
3+4+1= 8
Let us apply the part to all method
let the total cost be x
hence
3/8=315/x
cross multiply
3x= 8*315
3x= 2520
divide both sides by 3
x= 2520/3
x= $840
Hence the total money is $840
Extra Example 3: Hazel has $23.28 in her purse. She has $5.60 more than Nixon.
Paul says that Nixon has $28.88. Yolanda says that Nixon has $17.68. Who is
correct?
Answers
Answer:
Yolanda is correct.
Step-by-step explanation:
If Hazel has $23.28 and $5.60 more than Nixon, then Nixon will have $17.68 because 23.28-5.60 is 17.68.
The only way Paul would be right is if Nixon has $5.60 more than Hazel because 23.28+5.60 is 28.88.
