A Translation 4 units leftwards followed by a reflection across the x-axis.

Step-by-step explanation:

he transformations are:

Translation 4 units leftwards.

Reflection across the x-axis.

You can deduct this transformations by using one vertex. Notice that E(4, -9) and E'(0, 9). You can observe that the transformed coordinate has the inverse y-coordinate, which indicates a x axis reflection. Also, it was shifted 4 units leftwards only.

Answer:

40% increase

Step-by-step explanation:

10 is you 100%

if it increased to 14, then that means your 100% = 10 increased +4 which is the 40%

Answer:

Yes, in a Cartesian Coordinate system each point is given by two numbers. If the question is "where" the function has a max or min value, that's "x", the first number in pair. If the question is "what" is that max or min function value, thats "y", the second number in the pair

Now the formula for the area of a circle is: πr². So we take 3 and just put it into the equation. π·3²=28.27. This is the area of the circle. Now the rate of change I think would just be the difference between the radius and the area of the circle so 28.27-3=25.27.

The amount she invested in each account is:

$6,000 invested at 11%

$6,000 invested at 6%

Let x represent the amount invested at 11%

Hence:

.11x+.06(8000-x)=780

.05x+480=780

Collect like terms

.05x=300

Divide both side by .05x

x=300/.05

x=$6,000

Inconclusion the amount she invested in each account is: $6,000 invested at 11% and $6,000 invested at 6%.

To make a random selection using a random number generator, we could make use of a computer programming to execute the task by following the steps below ;

A.) Using python 3 to generate a random sample of 141 plots :

import random

#import the random module

random_sample = random.sample(range(1410), 141)

#using the sample method, randomly select a sample of 141 plots from the total number of plots, 1410

print(random_sample)

#display the randiy selected plots which is 10% of the total

B.) Choosing the first three plots using the method described in (A)

first_3 = random_sample[:3]

#from the 141 random samples, use list slicing to select the first three plots from the sample

print('\n The first 3 plots are : ' , first_3)

#display the first three sample plots selected.

Answer: y = -5/3x + 4 and 5x + 2y = 4

Step-by-step explanation:

1. Firstly, we should substract 5x on both sides of the equation.

3y = -5x + 12

Then we divide by 3 on both sides of the equation. This would give us our answer.

y = -5/3x + 4

2. The answer is 5x + 2y = 4.

The slope of parallel lines should be the same. If we want to isolate y of the above the equation we should first substract 5x on both sides.

2y = -5x + 4

Then we should divide 2 on both sides of the equation.

y = -5/2x + 4

The equation above and y = -5/2x -7 have the same slope. Therefore, they are parallel.

Answer:

Car a is moving at 15 miles per hour

Its slope is 15/1

Its equation is y = 15x

Car b is moving at 7.5 miles per hour

Its slope is 7.5

Its equation is y = 7.5x

Car a is moving twice as fast as car b

Step-by-step explanation:

But here's how you solve

Chose 2 points and find the change in y and change in x, then divide in the same order.

Point 1: (1, 15)

Point 2: (2, 30)

Change in y = 15

Change in x = 1

y = miles

x = hours

15 miles/1 hour

You can also do this

Pick a point and just divide it's y by its x. For example:

(4, 60)

60 miles/4 hours

15 miles per hour

Now that we have the slope, we can get the equation for the graph:

y = 15x + 0

or just y = 15x, because there is no y-intercept

Now let's solve for car b:

Chose a point:

(3, 22.5)

Divide its y by its x

22.5/3

7.5

Car b is moving at 7.5 miles per hour

Now that we have the slope, we can get the equation for the graph:

y = 7.5x + 0

or just y = 7.5x, because there is no y-intercept

Compare the speeds

Car a: 15 mph

Car b 7.5 mph

15 > 7.5

So, Car a > Car b

15/7.5 = 2

So Car a moves twice as fast as Car b

Answer:

2 7/20

Step-by-step explanation:

Therefore, 4 7/10 × 1/2 = 2 7/20.

Answer:

47/20

Step-by-step explanation:

Converting 4 7/10 into improper fraction:

((4*10)+7)/10

= (40+7)/10

= 47/10

Multiply 47/10 by 1/2

= 47/(10*2)

= 47/20
