Can someone could explain the part of simplifying rational expressions where it is x is not equal to a number. I've had a hard time understanding how to get that answer. The picture is an example in my notes.

Answer:

From the identity C + I + G + X = Y, where X represents exports, we see that the size of the multiplier depends on the marginal propensities to consume (MPC), which equals the proportion of income spent on consumption out of disposable income (Y - T). MPC = C/ (Y - T). Since we don't know the values of Y and T yet, we can't say what event might affect the multiplier without knowing their effects on T and Y. Answer e is incorrect as it assumes that the change in T only affects the government budget balance, not net tax revenue. Moreover, it also incorrectly assumes that reducing taxes increases disposable income instead of just increasing private sector savings.

Answer:

B

Step-by-step explanation:

Letter B as no solution. Because there are no values of x that make the equation true.

Answer:

Quotient does not need to be divided because quotient itsenf means answer.

Quotient means answer when we divide the dividend by the divisor.

Step-by-step explanation:

Let's call the shorter base of the trapezoid "b1", the longer base "b2", and the height "h". We can use the formula for the surface area of a right prism to set up an equation:

Surface area of prism = 2(base area) + (lateral area) = 1280

The base area is the area of the trapezoid, which is given by:

(base area) = (1/2)(b1 + b2)h

The lateral area is the area of the four rectangular faces of the prism, which are all congruent. Each face has an area equal to the product of the height and the length of one of the legs of the trapezoid, so the lateral area is:

(lateral area) = 4hl

where l is the length of one of the legs of the trapezoid.

Substituting these expressions into the formula for the surface area of the prism, we get:

2[(1/2)(b1 + b2)h] + 4hl = 1280

Simplifying and rearranging, we get:

h(b1 + b2) + 2hl = 1280

We also know that the sum of the lengths of the legs of the trapezoid is 52 feet, which means:

l1 + l2 = 52

But we can express l1 and l2 in terms of b1 and b2 using the formula for the area of a trapezoid:

(base area) = (1/2)(b1 + b2)h = (1/2)(l1 + l2)h

Simplifying, we get:

b1 + b2 = (l1 + l2)h

Substituting this into the previous equation, we get:

h[(l1 + l2)h] + 2hl = 1280

Simplifying, we get:

h^2(l1 + l2) + 2hl = 1280

Substituting l1 + l2 = 52, we get:

h^2(52) + 2hl = 1280

This is a quadratic equation in h. We can solve it using the quadratic formula:

h = [-2l ± sqrt(4l^2 + 4h^2(52)(1280 - 2hl))] / 2(52)

Simplifying and factoring out a 2, we get:

h = [-l ± sqrt(l^2 + h^2(1280 - 2hl))] / 52

We have two possible solutions for h, but one of them is negative, which doesn't make sense in the context of the problem. So we can discard the negative solution and focus on the positive one:

h = [-l + sqrt(l^2 + h^2(1280 - 2hl))] / 52

We don't know the exact value of h yet, but we can use this equation to set up a system of equations that we can solve for h. Specifically, we can use the fact that the legs of the trapezoid add up to 52 feet to solve for l in terms of b1 and b2:

l = 52 - (b1 + b2)

Substituting this into the equation for h, we get:

h = [-l + sqrt(l^2 + h^2(1280 - 2hl))] / 52

h = [-52 + (b1 + b2) + sqrt((52 - (b1 + b2))^2 + h^2(1280 - 2h(b1 + b

Subtract the balance from the original amount:

15 - 12.34 = 2.66

Now divide the amount spent by price per minute:

2.66 / 0.19 = 14

The call lasted 14 minutes.

Answer:

A) (-4,-3), B) (-1,1.5), D) (0,3)

Step-by-step explanation:

First turn 4y - 6x = 12 to slope intercept form

(y = mx + b), by adding 6x on both sides in order to move it to the other side. So now you have

4y = 6x +12, next divide both sides by 4 in order to get y by its self. Now you have y = 6/4x + 3, since 6 can't be divided by 4 yet 12 can.

The diameter of the small volcano 'Pico' would be = 8km

An isoline is defined as the line found on a map that has constant value of either distance, temperature or rainfall.

The isoline that is used in the given map above = 2000m.

The number of lines that surrounds the pico volcano = 4

Therefore the diameter of the volcano = 2000×4 = 8000m

The sequence with the given nth term is n-2. The first four terms of the sequence are a₁ = -1, a₂ = 0, a₃ = 1, and a₄ = 2. The term a₁₀ is equal to 8, a₉ is equal to 7, and a₁₅ is equal to 13.

The given nth term of the sequence is n-2, which means that each term is obtained by subtracting 2 from the corresponding value of n.

To find the first four terms of the sequence, we substitute the values of n from 1 to 4 into the nth term expression. Thus, we have a₁ = 1-2 = -1, a₂ = 2-2 = 0, a₃ = 3-2 = 1, and a₄ = 4-2 = 2.

To find a specific term, we substitute the corresponding value of n into the nth term expression. For example, a₁₀ = 10-2 = 8, a₉ = 9-2 = 7, and a₁₅ = 15-2 = 13.

In summary, the first four terms of the sequence are a₁ = -1, a₂ = 0, a₃ = 1, and a₄ = 2. The term a₁₀ is equal to 8, a₉ is equal to 7, and a₁₅ is equal to 13.

Exponential functions are mathematical functions that involve an exponent or power. There are two types of exponential functions: growth and decay.

1. Exponential Growth Functions: These functions have the form y = a*b^x, where a > 0 and b > 1. They model exponential growth, where the value of y increases rapidly as x increases. For example, the function y = 2^x is an exponential growth function, as the value of y doubles for each increase in x.

2. Exponential Decay Functions: These functions have the form y = a*b^x, where a > 0 and 0 < b < 1. They model exponential decay, where the value of y decreases rapidly as x increases. For example, the function y = (1/2)^x is an exponential decay function, as the value of y is halved for each increase in x.

Both types of exponential functions are important in many fields, including finance, biology, and physics. They are used to model phenomena such as compound interest, population growth, and radioactive decay.

Expression which represents the amount of money spend by each woman is equal to [ 9 + 1.35 + (one- half)(3.50 + 1.74)].

As given in the question,

Condition for the expression:

Sally and Anne both went for a movie.

Each one purchased a drink.

Shared one popcorn and one veggie bought by them.

Consider movie ticket price = 9

drink price = 1.35

Popcorn price = 3.50

Veggie price = 1.74

Explanation for different expressions are:

1. one-half (9 + 1. 35 + 3. 50 + 1. 74)

Here sum of all the amount is divided equally, which is not correct as movie ticket and drink they have purchased individually.

2.  9 + 1. 35 + one-half (3. 50 + 1. 74)

This is correct option as it represents :

Movie ticket price = 9

Drink = 1.35

one-half (3. 50 + 1. 74) = one popcorn and one veggie divided equally.

3. 18 + 2. 70 + one-half (3. 50 + 1. 74)

As per consideration of price this is not correct option.

Movie ticket price =18

Drink = 2.70

one-half (3. 50 + 1. 74) = one popcorn and one veggie divided equally.

4. 9+1. 35+2(3. 50+1. 7)

This is not correct option as popcorn and veggie price is doubled.

Therefore, expression which represents the amount of money spend by each woman is equal to [ 9 + 1.35 + (one- half)(3.50 + 1.74)].

Answer:

1 bag of CB = 10.5 bags of candy corns

Step-by-step explanation:

The kids have an agreement on how to trade their goods:

1 piece of bubble gum (BG) = 4 candy corns (CC)

1 lollipop (LP) = 3 pieces of bubble gum (BG)

1 candy bar (CB) = 2 lollypops (LP)

This last equivalence will be expanded by using back the other agreements:

1 CB = 2 LP

But since:

1 LP =3 BG, then

1 CB = 2 * 3 GB = 6 GB

Also 1 GB = 4 CC, thus:

1 CB = 6 * 4 CC = 24 CC

1 candy bar = 24 candy corns

If we multiply by 35:

35 candy bars = 35 * 24 candy corns

But 35 candy bars = 1 bag of CB, thus

1 bag of CB = 35 * 24 candy corns

If we now divide by 80:

1 bag of CB = 35 * 24 / 80 bags of candy corns

Operating:

1 bag of CB = 10.5 bags of candy corns

The amount for the deposit is $25350, monthly payment is $1436.5 and the total amount that Sipho pays is $178492.

Given price of car $169000, deposit of 15%, monthly installments being 1% of left over price and number of years be 9 years.

We have to find the amount of deposit, monthly installments and the total amount paid by Sipho.

We have been told that deposit is 15% of total amount. So the deposit will be 15%*169000=$25350.

Monthly installment is 1% of the left over amount.

left amount=169000-25350=$143650.

Monthly installment being =143650*1/100

=$1436.5

Total amount paid by Sipho=deposit +installment amount  * numberof installments

Number of installments=12*9

=108

Total amount=25350+1436.5*108
