Answer:
X^2-x- 8/x+4
Step-by-step explanation:
X+4 becomes a negative 4
Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.
I need some help pretty please!
Answer:
Number & Cost($)
Feet & Yards
Step-by-step explanation:
Number & Cost:
(2, 38), (4, 76) <====== pick any two point to find constant
constant = (y₂ - y₁) / (x₂ - x₁)
= (76 - 38) / (4 - 2)
= 38 / 2
= 19 <====== k the constant
y = kx
y = 19x
point (2, 38): 38 = 19(2) ===> 38 = 38
point (4, 76): 76 = 19(4) ===> 76 = 76
point (7, 133): 133 = 19(7) ===> 133 = 133
point (9, 171): 171 = 19(9) ===> 171 = 171
Feet & Yards:
(27, 9), (75, 25) <====== pick any two point to find constant
constant = (y₂ - y₁) / (x₂ - x₁)
= (25 - 9) / (75 - 27)
= 16 / 48
= 1/3 <====== k the constant
y = kx
y = 1/3x
point (3, 1): 1 = 1/3(3) ===> 1 = 1
point (12, 4): 4 = 1/3(12) ===> 4 = 4
point (27, 9): 9 = 1/3(27) ===> 9 = 9
point (75, 25): 25 = 1/3(75) ===> 25 = 25

c. Expand: (tan(theta) - 1)^3
Answer:
(tan(theta)-1)^3
= (tan(theta)-1)(tan(theta)-1)(tan(theta)-1)
= (tan^2(theta)-2tan(theta)+1)(tan(theta)-1)
= tan^3(theta)-2tan^2(theta)+tan(theta)-tan^2(theta)+2tan(theta)-1
= tan^3(theta)-3tan^2(theta)+3tan(theta)-1

Please help! Only if you KNOw, I’m confused
Answer:
40
Step-by-step explanation:
1.Kknow the following information;
Remember, the sum of degrees of angles in a triangle is 180.
So say if a traingle contained;
<1, <2, <3,
Then:
<1 + <2 + <3 = 180
2. State the given, and set up an equation;
In this case, it is given that;
<1 = 115
<2 = 25
Therefore, set up the equation;
115 + 25 + <3 = 180
3. Solve the equation;
115 + 25 + <3 = 180
Simplify,
140 + <3 = 180
Inverse operations,
140 + <3 = 180
-140 -140
<3 = 40

The graph in the question is missing.
Answer:
y = [tex]\frac{-1}{4}( x^3 + 2x^2 - 32x -96)[/tex]
Step-by-step explanation:
The function is cubic
It has roots as -4, -4 , 6
this means the value of x = -4, -4 , 6 which makes the entire equation zero
so we have solutions as
x+4 = 0
x+4 = 0
x- 6 = 0
on forming a cubic equation using these
(x+4)(x+4)(x-6)
the equation passes through (2,36)
put x = 2
(2+4)(2+4)(2-6) = (6)*(6)*(-4)
which exceeds 36 so we product the equation with -1/4 to get 36
Final equation
y = [tex]\frac{-1}{4} (x+4)(x+4)(x-6)[/tex]
y = [tex]\frac{-1}{4}( x^3 + 2x^2 - 32x -96)[/tex]

Step-by-step explanation:
x = 13
Answer:
I think its 13
Step-by-step explanation:
because the line above it which is 18 looks like the same length. So I would subtract 5 from 18 to get 13. because 13+5 is 18. Good luck!!

Mrs. Clarke saved $60 by buying a dress at a 30% discount. The original price of the dress was
Answer:
$200Step-by-step explanation:
Step one:
given
let the original price of the be x
discount = 30%
30 of x is $60
Step two:
Mathematically
30/100*x=60
0.3x=60
divide both sides by 0.3
x=60/0.3
x=200
Hence the original price of the dress is $200

The transformation formula of a horizontal-facing parabola is:
x = ±a(b(y - k)) + h, where the vertex is at (h, k).
Looking at the graph, we can see a vertex at (-2, -3) with a stretch of 2. The graph is also pointed towards the RIGHT, which means that the coefficient "a" must be positive. Therefore:
The only logical answer choice is B, or x = 2(y + 3)² - 2.
The formula indicates that:
* Vertex at (-2, -3)
* Stretch of 2
* Right-facing parabola
