Answer:
Step-by-step explanation:
1). y = - 4x + 7
Reflected across what????
if x-axis, then y ⇒ - y
So the answer would be y = 4x - 7
2). y = 2x - 14
3). y = 2x - 8
4). y = 12x + 9

Prices for a day ticket entrance at the Disneyland Paris Resort are as follows: Work out the percentage discount offered with the family ticket option.
Answer:
15% discount
Step-by-step explanation:
To find the discount first we need to find out the cost without the family ticketNow the family ticket covers 2 Adults and 2 children, but how much is that using the standard prices?So [tex]2adults= 2*(55)=110[/tex] which is Euros I believeThen [tex]2children= 2*(45)=90[/tex] We add these together 110+90=200 Euros, that's how much 2 adults and 2 children cost with standard pricesNow the family ticket only charges 170 EurosSo how much less is the family ticket to the regular price? 200-170=30 EurosThat's the discount, now what percentage of the actual price 200 Euros, is 30 Euros?First we write it as a fraction; 30 Euros out of 200 Euros which is [tex]\frac{30}{200} =\frac{3}{20}[/tex] To find the percentage, we multiply the fraction by 100[tex]\frac{3}{20} *100=\frac{3*100}{20}=\frac{300}{20} =15percent[/tex] or 15%This just means "take out 15% of 200 from the 200 Euros original price" so that's the percentage discount that the family ticket providesAnswer:
15%
Step-by-step explanation:
Twenty percent of all telephones of a certain type are submitted for service while under warranty. Of these, 60% can be repaired, whereas the other 40% must be replaced with new units. If a company purchases ten of these telephones, what is the probability that exactly three will end up being replaced under warranty
Answer:
the probability that exact three would be replaced under each warranty is 0.34
Step-by-step explanation:
The computation of the probability that exact three would be replaced under each warranty is as follows
Given that
Submitted under warranty = P = 20%
Replaced with the new units = 40%
So replaced and submitted would be
= 40% × 20%
= 80%
Now let us assume the number of telephones be x for ending up for replacement
Total number of telephones purchased is 10
Now the probability by applying the formula of binomial probability is
[tex]P(X) = n_C_xp^x(1 - p)^{n-x}[/tex]
[tex]P (X = 3) = ^{10}C_3(0.08)^3 (1 - 0.08)^{10 - 3}\\\\= \frac{10!}{3!(10! - 3!)} (0.08)^3(0.92)^7\\\\[/tex]
= 0.34
Hence, the probability that exact three would be replaced under each warranty is 0.34

The sum of two numbers is -124. one number is 22 less than the other. Find the numbers
Answer: -51 and -73
Step-by-step explanation:
Let the first number be x.
Let the second number be x-22.
Since the sum of two numbers is -124, this means that:
x + x - 22 = -124
2x - 22 = -124
2x = -124 + 22
2x = -102
x = -102/2
x = -51
Since the second number is x - 22. This will be:
= x - 22
= -51 - 22
= -73
The numbers are -51 and -73

Answer:
11 1/2 teaspoons
Step-by-step explanation:
1 2/4 basil= 1.5 tsp If you multiply this by two to double the recipe you will have 3 teaspoons of basil.
1/4*2= 2/4 pepper
4*2=8 parsley
After you double everything you need to add them together:
3+2/4+8
Which brings you to the final answer of 11 2/4 teaspoons or if you simplify it.... 11 1/2 teaspoons

If 200 men can make an embankment 3km long in 25 days, how much overtime per day must 60 men work to complete an embankment 2km long in 32 days, 12 hours being a day's work?
Answer:
Each man would have to work 7.2 overtime hours per day if they wanted to meet the goal.
Step-by-step explanation:
If 200 men can make a 3 km long embankment in 25 days, their work day being 12 hours, to determine the amount of work that each one does, the following calculation must be made, taking into account that 3 km is the same at 3,000 meters:
3000/25 = 120 meters per day
120/200 = 0.6 meters per day per man
0.6 / 12 = 0.05 meters per hour worked per man
Therefore, to determine the extra work time that 60 men should carry out, if they wanted to complete a 2 km long embankment in 32 days, the following calculation should be performed:
2000/32 = 62.5 meters per day
62.5 / 60 = 1.04 meters per day per man
1.04 / 12 = 0.08 meters per hour worked per man
Therefore, that difference of 0.03 meters must be taken into account to determine the extra time of work that these men must carry out, carrying out the following cross multiplication:
0.05 = 12
0.08 = X
((0.08 x 12) / 0.05) = X
(0.96 / 0.05) = X
19.2 = X
Therefore, each man would have to work 7.2 overtime hours per day if they wanted to meet the goal.
12. Emani says, "If you subtract 18 from my number and multiply the difference by -6, the result is -36." What is Emani's number? Your answer
Answer:
24Step-by-step explanation:
Step one:
let the number be x
given
1. x-18
2. (x-18)*-6
3. (x-18)*-6=-36
Required
x
the final expression mathematically is '
(x-18)*-6=-36
open bracket and solve for x
-6x+108=-36
collect like terms
-6x=-36-108
-6x=-144
divide both sides by -6
x=144/6
x=24
Emani's number is 24
A racecar driver is doing a time trial of a new car on a straight back. The car's distance from the timekeeper is represented by y=293x+50 where x is time in seconds and y is the distance from the timekeeper's position. How many feet from the timekeeper is the race car at the beginning?
Answer:
50 feet
Step-by-step explanation:
The car's distance from the timekeeper us given by :
y = 293x+50
Where x is time in seconds and y is the distance from the timekeeper's position.
The general equation of a line is given by :
y = mx +c
On comparing, we get : c = 50
It means the timekeeper has covered 50 feets at the beginning.
