The lines described by y = (a + 12)x + 3 and y = 4ax are parallel. what is the value of a

Answers

Answer 1

The lines are parallel if and only if the values of their slopes are equal. In a standard form of the equation of the line, the slope is the numerical coefficient of x. Given this condition, we determine the value of a by equation a + 12 and 4a.

    Slope = a + 12 = 4a

 The value of a from the equation is 4.

Answer: 4

One way to find the total cost of a jacket for $55.80 with a sales tax of 2.7% is 55.80+0.027(55.80) write an equivalent expression to show another way to find the total cost

Answers

Final answer:

To find the total cost of a jacket with sales tax, you can either use the given expression or calculate the sales tax separately and add it to the original price.

Explanation:

To find the total cost of a jacket with a sales tax, you can use the expression 55.80 + 0.027(55.80) as mentioned in the question.

Another way to find the total cost is to calculate the sales tax first and then add it to the original price of the jacket. To do this, you need to multiply the original price of the jacket by the sales tax rate (2.7% or 0.027) and then add the result to the original price: 55.80 + (0.027 * 55.80).

Tanner walked a total of 8 kilometers by making 2 trips to school. How many trips will Tanner have to make in all to walk a total of 12 kilometers?

Answers

3. every trip it's 4 kilometers, and 4 times 2 equals 8 so 4 times 3 equals 12 so yeah :))

The total number of trips is x to walk a total of 12 kilometers is 3 trips if Tanner walked a total of 8 kilometers by making 2 trips to school.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Tanner walked a total of 8 kilometers by making 2 trips to school.

Let the total number of trips be x to walk a total of 12 kilometers.

8 km → 2 trips

12 km → x trips

8x = 24

x = 24/8

x = 3 trips

Thus, the total number of trips is x to walk a total of 12 kilometers is 3 trips if Tanner walked a total of 8 kilometers by making 2 trips to school.

Which functions have graphs that are steeper than the graph of f(x)=−3x^2 ?

Steepness in quadratic functions refers to how wide or narrow the graph is.

Positive/negative doesn't affect steepness in this situation so A would be out because it is essentially the same as the problem.

You would have to use graph transformations. When a number is front of the whole equation like how 3 is in front of x^2, it stretches the graph VERTICALLY making the graph MORE STEEP.

How to find the equation of a parabola given the vertex and one point?

Answers

first, write down y=a(x-the x coordinate of the vertex)^2+the y coordinate of the vertex)
second, plug the x coordinate and coordinate of the given point in the above equation to find out a
For example, vertex is (1,2), the point is (3,4)
y=a(x-1)^2+2 
then plug in x=3, y=4 in the above equation to find out a
4=a(3-1)^2+2
4=4a+2
4a=2
a=1/2
the equation of the parabola with a vertex at (1,2) and passes through the point (3,4) is 0.5(x-1)^2+2
Final answer:

To find the equation of a parabola given the vertex and one point, use the vertex form of a parabola equation: y = a(x - h)² + k.

Explanation:

To find the equation of a parabola given the vertex and one point, you can use the vertex form of a parabola equation: y = a(x - h)² + k. Here's how:

Determine the values of h and k from the given vertex.Use the given point to substitute the values of x and y in the vertex form.Solve for a to find the equation of the parabola.

For example, if the vertex is (2, 3) and the point is (4, 5), the equation of the parabola would be y = 1(x - 2)² + 3.

hm, if order does not matter
then it is 3/10 that one of the 3 is chosen
assuming that one was chosen, we now have a probablity of 2/9
then the last is 1/8

so the ending probablity will be 3/10 times 2/9 times 1/8 or 6/720 or 1/120

the probablity will be 1/120

if the order does matter then it is

In a shopping mall, shoppers who use a reward points card get a 10% discount on every transaction. If the average transaction is $450 for customers with these cards, and $500 for other customers, what happens to the expected value of a transaction?

Answers

Final answer:

The expected value of a transaction decreases by 10% for customers using a rewards points card, going from $500 to $450 per transaction as they receive a 10% discount.

Explanation:

The question pertains to the expected value of a transaction at a shopping mall considering different discounts for customers who use a rewards points card. The expected value takes into account the average (mean) value of transactions and the discounts applied to those transactions. With shoppers using the rewards card receiving a 10% discount, the average transaction value for these customers is $450, compared to $500 for those without the card.

If we calculate the expected value for a transaction without considering the card, it would simply be the average transaction amount of $500. However, when including the rewards card usage, we have to account for the discount. Therefore, the expected value for a transaction from a customer using the rewards card is 10% less than $500, which equals $450. This means the expected value for a transaction with the card has decreased by $50 compared to customers without the card.

To summarize the effect, use of the rewards card reduces the expected value of transactions for the business, given that a discount is provided. On the other hand, it incentivizes customers with savings, potentially increasing customer loyalty and the frequency of visits, which might offset the decrease in expected transaction value in a broader business strategy.

Answers

UW is 1/2 KL so that one is out 
UV is parallel to JL that's correct
JK is 2VW that's correct
UV and UK aren't congruent
UW and UV aren't congruent

The only correct statements in relation to the given triangle are;

JK = 2VW

UV ║ JL

1) UW = VW; This is not correct because we see that UW forms a parallel line to KV but there is nothing to show about it being equal to VW.

2) UV = UK; This is not correct because there is no sign of them being congruent to each other.

3) JK = 2VW; We see that UKVW forms a rhombus. This means that parallel sides are equal. Thus; UK = VW.

Since UK is equal to UJ from the triangle, then;

2UK = JK

Since UK = VW, then; 2VW = JK. Thus, the statement is true.

4) UW = 12KL; This is not correct because UW = KV = KL/2 from the diagram.

5) UV ║ JL; This statement is correct because from the diagram UV is a side of the parallelogram UVLW with UV parallel to WL since opposite sides of a parallelogram are equal.
