Answer:
2
Step-by-step explanation:
(x)(y) = k Inverse relationship
(4)(3) = k
12 = k
(6)(y) = 12
y = 2
Answer:
When y=3, x=4 but when x=6, y is :---
[tex] \frac{3}{4} = \frac{y}{6} \\ y = \frac{3 \times 6}{4} \\ y = \frac{9}{2} \\ \boxed{ y = 4.5}[/tex]
★ Value of y is 4.5Jim buys a skateboard for $200. The value of the skateboard depreciates by 15% each year
since buying it. Create a function to represent the value of the skateboard, f(2), in dollars,
after 3 years since buying it.
Answer: f(x)=200•(0.85)^x
Step-by-step explanation:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
Depreciation is often modeled as an exponential decay function. Since Jim bought a skateboard for Co=$200, its value will depreciate by r=15% = 0.15 each year since buying it.

3. A computer is priced at $65,000 plus value added tax at 15%. What amount does the computer actually cost the customer?
Answer:
$74,750
Step-by-step explanation:
Given that,
The cost of a computer = $65,000 + value added tax at 15%
We need to find the amount the computer actually cost the customer.
Total cost = Cost of computer + VAT at 15%
[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]
So, the computer actually cost the customer is $74,750.

Answer:
56 degrees
Step-by-step explanation:
A straight angle is 180 degrees
91 + 33 = 124
180 - 124 = 56
Check:
124 + 56 = 180
Answer:
C=56
Step-by-step explanation:
You subtract the sum of 33 + 91 from 180 which would you give you c=56

7. Expand and reduce A(x). Then calculate A(x) for x=1.
A (x) = (3x – 3)(3x + 2)
Given:
The function is
[tex]A(x)=(3x-3)(3x+2)[/tex]
To find:
The simplified form of A(x) and value of A(x) at x=1.
Solution:
We have,
[tex]A(x)=(3x-3)(3x+2)[/tex]
[tex]A(x)=(3x)(3x)+(3x)(2)+(-3)(3x)+(-3)(2)[/tex]
[tex]A(x)=9x^2+6x-9x-6[/tex]
[tex]A(x)=9x^2-3x-6[/tex]
Putting x=1, we get
[tex]A(1)=9(1)^2-3(1)-6[/tex]
[tex]A(1)=9-3-6[/tex]
[tex]A(1)=9-9[/tex]
[tex]A(1)=0[/tex]
Therefore, the simplified form of A(x) is [tex]A(x)=9x^2-3x-6[/tex] and the value of A(x) at x=1 in 0.

Point B (-4,4) and D (10,4) lie on circle G. The line segment connecting the two points
Answer:
BD = 14units
Step-by-step explanation:
To get the distance of the line connecting the two points, we will use the formula for calculating the distance between two points
D = √(x2-x1)²-(y2-y1)²
D = √(10-(-4))²-(4-4)²
D = √(10+4)²
D = √(14)²
D = 14unit
Hence the distance between the two points is 14units
Factorise 2x^2 + 5x + 2
Answer:
(x+2)(2x+1)
Step-by-step explanation:
x times 2x is 2x^2
x times 1 is x
2 times 2x is 4x
2 times 1 is 2
Overall
2x^2+x+4x+2
add x and 4x:
2x^2 + 5x + 2
So (x+2)(2x+1) is the answer
Answer:
( x + 2 ) , ( 2x + 1 )
Step-by-step explanation:
2x² + 5x +2
2x² + 4x + x +2
2x ( x + 2 ) +1 ( x + 2 )
( x + 2 ) , ( 2x + 1 )

Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.
Sine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:
[tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex]
In triangle LMN:
We can find the length of l using sine rule:
[tex]\frac{l}{sinL}=\frac{n}{sinN} \\\\substituting:\\\\\frac{l}{sin(11)}=\frac{92}{sin(46)} \\\\l=\frac{92}{sin(46)}*sin(11)\\\\k=24\ inches \\[/tex]

The function f(x) is a quadratic function and a limited table of values is provided
below. Write the equation of the quadratic polynomial in standard
form.
Answer:
x^2 - x - 12
Step-by-step explanation:
The quadratic will have the form f(x) = ax^2 + bx + c
Note that when x = 0, y = -12. Thus, we have f(0) = a(0)^2 + b(0) + c = -12, and the function (so far) is f(x) = ax^2 + bx - 12.
Arbitrarily choose two more ordered pairs from the table. I've chosen (-3, 0) and (-4, 8).
For (-3, 0), the quadratic becomes 0 = a(-3)^2 + b(-3) - 12, or:
0 = 9a - 3b, and
For (4, 8), f(4) = 8 = a(4)^2 + b(8), or 8 = 16a + 8b, or 1 = 2a + b, or b = 1 - 2a
Solve 0 = 16a + 4b and b = 1 - 2a for a and b.
Let's use substitution: Substitute b = 1 - 2a into 0 = 9a - 3b or 3a - b = 0:
3a - 1 - 2a = 0, or a = 1.
Since b = 1 - 2a, we get b = 1 - 2(1) = -1
and so a = 1, b = -1 and c = -12
Then the polynomial must be: x^2 - x - 12
Which of the following are characteristics of the graph of the absolute value
parent function?
Check all that apply.
O A. It goes through the origin.
O B. The right half has a slope of -1.
O C. It is in quadrants I and II.
D. It is V-shaped.
Answer: C) It is in quadrants I and II
A) It goes through the origin
D) It is V-shaped
explanation: The graph of the absolute value parent function will be V-shaped. The absolute function is also known as the mode function. The value of the absolute function is always positive. The absolute function is given as f(x) = | x – h | + k
The graph of the absolute value parent function will be V-shaped.
The characteristics of the graph of the absolute value parent function are; A) It goes through the origin, C) It is in quadrants I and II and D) It is V-shaped
What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.
|x| = -x, x < 0.
This measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0, and has vertex at (0,0). The range is from the y-coordinate of the vertex to positive infinity.
Vertex (2, 0), Range: {y | 0 ≤ y < ∞}
Since graph of the absolute value parent function will be V-shaped. The absolute function is also known as the mode function.
The value of the absolute function is always positive. therefore the absolute function is given as ;
f(x) = | x – h | + k
The graph of the absolute value parent function will be ;V-shaped.

It's 7.723, not 5.79.
If you get your bodmas correctly, you should get 7.723.
Solution:
Do "((-4.6) - 1.9) first, which is -6.5 basically.
After that it is (-2.78) x (-2.8), which is 7.784.
After that do (2.2 - 1.8) ÷ ((-4.6) - 1.9), which is -0.061
After that 7.784 + -0.061, which makes it 7.723.
Factorise the following:
10 – x^2
Answer:
It cant be further factorise...you may have missed a value.
10 and x square have nothing in common, nor is there any mid number for mid-term breaking, nor any two square numbers to apply identities. If yu can reveiw he question...which I think might be 100-x^2....the answer will be
(10-x)(10+x)
