Quadrilateral ABCD with vertices A(-9, 2), B(-8, 8), C(-4, 6), and D(-2, 2) is shown. You want to reflect quadrilateral ABCD in the
vertical line that passes through the midpoint of BC . Graph the line of reflection and the image after the reflection.

Answers

Answer:

See explanation.

Step-by-step explanation:

Graph the quadrilateral. By inspection, you can tell where the midpoint is. (see attachment 1)

Now, I'll draw a line through it. (see attachment 2)

To reflect across a line, think about the points traveling across the line the same number of spaces the point is from the line. For example, point A is three away from the line. So, A' will be 3 away from the other side. The coordinates will be at (-3,2). (see attachment 3).

Do the same for the other points, and you'll have your image.

Isabella's Flower Shop sells a variety of flowers. Roses cost $5 each. The shop gives a discount of $1 off per rose if more than 10 are bought. Daisies are sold in bunches of 6 flowers and cost $4 per bunch. • Nala bought 12 roses for her friend's going-away party. • Hector bought his mother 4 bunches of daisies for her birthday. • Petunias cost $2 more per bunch than daisies. Use the axioms to make three conclusions about the flowers Isabella sells.​

Answers

Answer:

Isabella earned $48 from Nara. Isabella earned $16 from Hector. Isabella sells petunias for $6 per bunch (the number of petunias per bunch is unclear).

Step-by-step explanation:

Nala bought 12 roses which is greater than 10. So she received a $1 discount for each one. Nara spent 12*4=$48 dollars.

Hector bought 4 bunches of daisies meaning  that Hector spent 4*4=$16.

Petunias cost $6 per bucnh.

✔️Rate of change using two points on the line, say (2, 60) and (3, 75);

Rate of change (m) = ∆y\/∆x = (75 - 60) / (3 - 2) = 15/1

Rate of change = 15

This means each class costs $15

✔️Initial value is the y-intercept (b). It represents the initial start-up fee.

To find initial value/y-intercept (b), substitute m = 15 and (x, y) = (2, 60) into y = mx + b.

Thus:

60 = 15(2) + b

60 = 30 + b

60 - 30 = b

30 = b

b = 30

Therefore, initial start-up fee is $30.

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $2,542 was collected on the
sale of 1,158 tickets. How many of each type of ticket were sold?
The basketball game sold
adult tickets and
student tickets.

Answers

Answer:

#adult tickets sold = 346

#student tickets sold = 812

Step-by-step explanation:

let 'x' = # adult tickets sold

let 'y' = # students tickets sold

System of Equations:

x + y = 1158

5x + y = 2542

I used the elimination method and multiplied the first equation by -1

  -x - y = -1158

+ 5x + y = 2542

  4x  =  1384

   x = 346

346 + y = 1158

y = 812

The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]D = 25 + 0.3X[/tex]

The question has missing details; as what's required is not stated.

However, since it is a linear equation, possible questions could be

1. Determine the slope

2. Determine the D-intercept

3. Calculate the amount in dollars for (say) 5 miles

An equation is represented as:

[tex]D = b + mx[/tex]

Where

[tex]b = D\ intercept[/tex]

[tex]m = slope[/tex]

By comparing: [tex]D = 25 + 0.3X[/tex] to [tex]D = b + mx[/tex]

[tex]b = 25[/tex] and [tex]m = 0.3[/tex]

This means that the slope is 0.3 and the d intercept is 25

To get the amount for 5 miles, we substitute 5 for x in [tex]D = 25 + 0.3X[/tex]

[tex]D = 25 + 0.3 * 5[/tex]

[tex]D = 25 + 1.5[/tex]

[tex]D = 26.5[/tex]

The cost of 5 miles is $26

In the year 2005, there were 100 rabbits in a particular region. Since then, the population has increased by 3.4% per year. Write an expression that represents the rabbit population in the year 2025, and solve it.

Answers

Answer:

Step-by-step explanation:

Your answer

Ok, lets do it systematically.

2005– 100 rabbits

3.4 % per year increasement.

So every year it increase 0.034 *100 = 3.4 per year

Total 2025-2005= 20 years

So expression is : 0.034*100*year(20)

Answer is : 3.4*20 = 68. So, in 2025, total rabbits will be 168
