The total number of combinations is given by the product between the numbers of options, so there are 8 combinations.
How many combinations are possible?Here we have 3 variables and each can take two values:
x = {x₁, x₂}
y = {y₁, y₂}
z = {z₁, z₂}
The total number of combinations is equal to the product between the number of options that we have for each variable, then the number of combinations is:
C = 2*2*2 = 4*2 = 8
C = 8
There are 8 combinations.

The fare for taxi journeys in a certain town is $2.00 plus $1.00 for each kilometre. Using this information, estimate: (i) The fare for a journey of 3.5 km. (ii) The distance travelled if the fare was $6.00
Answer:
Step-by-step explanation:
Since the journey initially costs $2 (this will be our y-intercept), and the variable (x) is $1 for every additional kilometer. This can be modelled as...
y=1x+2
(i) if we want to know the cost of what 3.5 km would cost, we simply plug it into our equation...
y=1(3.5)+2
Answer: $5.5
(ii) For this question you can set the y value equal to 6 and plug in a random number for x until you get 6 on both sides. In this case...
6=1x+2
6=1(4)+2
The distance traveled if the fare was $6 is 4km

y=−x+2 y=3x−4 khan
Answer: 0
Step-by-step explanation:
2y -3x - 4 = 0
Subtract 2y from both sides of the equation.
-3x - 4 = -2y
Add 4 to both sides of the equation.
-3x = -2y + 4
Divide each term by -3 and simplify
6.5. Does Spending Measure Welfare? Suppose a community spends $1 million on salaries and equipment for its police department. Because it believes that citizens are now more law-abiding, the community decides to cut back on the number of police it employs. As a result, the community now spends $800,000 less on police officers. The crime rate remains the same.
a. What happens to measured GDP?
b. Does GDP accurately reflect welfare in this case?
Discuss the underlying issue that this example poses.
Answer:
(a) Measured GDP will decrease by $200,0000
(b) No
Step-by-step explanation:
(a) Gross Domestic Product (GDP) is the total value in monetary terms of al the goods produced in a geographic location.
There will be a $200,000 decrease in the value of the GDP of the community as a result of reduction in the community spending from $1 million to $800,000.
(b) Generally, GDP is not a true indicator of welfare, likewise in this case, GDP does not reflect the welfare of the community.
There's a decrease in the community spending from $1 million to $800,000 but there's an increase in the welfare of the community as a result of decrease in crime rate.
Given the vertex of a parabola is (-3,1) and also contains the point (-4,-1). State the exact equation of the parabola in vertex form, show all your work.
Answer:
y = -2(x + 3)^2 - 1
Step-by-step explanation:
The vertex equation of a parabola is y = a(x - h)^2 + k. If the vertex here is (-3, 1), then this equation becomes y = a(x + 3)^2 + 1.
Knowing that the graph passes through (-4, -1), we let y = -1 and x = -4, obtaining:
-1 = a(-4 + 3)^2 - 1, which must be solved for a:
-1 = a - 1. Therefore, a = -2, and the exact equation of this parabola is:
y = -2(x + 3)^2 - 1

Answer:
∠A = 6x + 4
Step-by-step explanation:
Hello There!
We are given the exterior angle ∠ACD and an interior angle ∠B
If you didn't know this is the rule for exterior angles of a triangle:
An exterior angle is equal to the sum of its opposite interior angles
so ∠ACD = ∠A + ∠B ( ∠A and ∠B being the opposite interior angles)
So with the information that we are given we plug them into their corresponding angle
then we would have
8x+5 = ∠A + 2x + 1
now we solve for A
Well how do we solve for A?
Well we have to isolate the variable
To do so we want to get rid of 2x + 1
We do that by subtract each side by 2x and 1
8x + 5 - (2x + 1 ) = 6x + 4
we're left with
∠A = 6x + 4
1-cosx/1+cosx=secx-1/secx+1

Dollhouse furnishing come in different sizes depending on the size of the doll house. Whyyy ratio of the size of the dollhouse item to the size of the larger item dollhouse piano: 1 3/4 in. High real piano: 3ft 6in. High
Answer:
1: 24
Step-by-step explanation:
The ratio = size of smaller object/size of larger object = Height of dollhouse piano, h/height of real piano, H
H = 3 ft 6 in = 12 in/ft × 3 ft + 6 in = 36 in + 6 in = 42 in
h = 1³/₄ in = 7/4 in
So ratio = h/H = 7/4 in ÷ 42 in = 7/4 in × 1/42 in = 1/4 × 1/6 = 1/24
So ratio = h/H = 1/24 ⇒ h:H = 1: 24

Avery deposited 1250 in a new savings account. Which amount is closest to the balance of the account at the end of three years
Answer: $1,467.80
Step-by-step explanation:
The formula for the future value given annual compounding is:
= Amount * ( 1 + rate) ^ number of years
The amount after 3 years at 5.5% is therefore:
= 1,250 * ( 1 + 5.5%)³
= 1,250 * 1.174241375
= $1,467.80

(b) Write down the coordinates of the turning point of y = x^2 - 2x - 4
Answer: [tex](1,-5)[/tex]
Step-by-step explanation:
Given
Curve is
[tex]y=x^2-2x-4[/tex]
At the turning point of the curve, the slope will be zero.
Differentiate the curve
[tex]\Rightarrow y'=2x-2[/tex]
Substitute 0 for [tex]y'[/tex]
[tex]\Rightarrow 2x-2=0\\\Rightarrow x=1[/tex]
[tex]\therefore y=1^2-2\times 1-4=-5[/tex]
[tex](1,-5)[/tex] is the turning point
