Using ƒ(x) = 2x + 7 and g(x) = x − 3, find ƒ(g(-2)).
Answer:
We conclude that:
f(g(-2)) = -3
Step-by-step explanation:
Given
f(x) = 2x + 7g(x) = x-3To determine
f(g(-2)) = ?In order to determine f(g(-2)), first we need to determine g(-2)
so substituting x = -2 in g(x) = x-3
g(-2) = -2 - 3
= -5
Thus,
f(g(-2)) = f(-5)
now substitute x = -5 in the function f(x) = 2x+7
f(x) = 2x+7
f(-5) = 2(-5) + 7
f(-5) = -10 + 7
f(-5) = -3
so
f(g(-2)) = f(-5) = -3
Therefore, we conclude that:
f(g(-2)) = -3

Maddie can not decide which of two Ski sets to buy. The original price of each is $850. The first ski set is marked 50% off. The second was marked down by 30% then a few days later an additional 20% off. 1. Find the sale price of the first ski set... 50% off. Show your work. 2. Find the Sale Price of the Second Ski Set Marked 30% then 20%. Show your work. 3. Which one is a better deal for Maddie and why?
Answer:
$425i. $595 ii. $476First skiStep-by-step explanation:
1. The first ski was valued at $850 but was then given a 50% discount. The sales price will therefore be:
= 850 * ( 1 - 50%)
= 850 * 50%
= $425
2. The first one was first discounted by 30% so the sales price was:
= 850 * ( 1 - 30%)
= 850 * 70%
= $595
It was then marked down by a further 20%:
= 595 * ( 1 + 20%)
= $476
3. The first ski is a better option because the discount makes it cheaper than the second ski even after the second ski had been discounted twice.

A garden patio is covered wit grey slabs and yellow slabs .1/5 of the slabs are grey a)write down the ratio of grey slabs to yellow slabs give your answer in its simplest form b)there are 55 slabs in total work out the number of yellow slabs
Answer:
1:u
Step-by-step explanation:
Grey slabs = 1/5 of total slab
Say total slab = x
Then,
Grey slabs = 1x/5
We can represent
Yellow slabs = u/5
Then ratio of Grey to yellow would be;
Gray slabs / Yellow slabs = (1x/5)/(u/5)
=1/u
= 1:u
Since there are 55 slabs in total, then
Yellow slab would be = 55/5 = 11

please please please help quick
Answer:
[tex]3\sqrt{5}[/tex]
Step-by-step explanation:
Since the triangle has a right angle, we are going to use pythaogoran theoem, which is [tex]a^{2} +b^{2} =c^{2}[/tex], where a and b are the legs and and c is the hypotunese/ slated side. Let set it up.
[tex]3^{2} +6^{2} =c^{2}[/tex]
9+36=c^2
45=c^2
[tex]\sqrt{45}[/tex]=
Then we are going to find a perfect squarre root(1,4,9,16,25....) to simplify the radical
The perfect square root is 9 because 9 goes into 45 5 times.
[tex]\sqrt{9x5}[/tex]
Then take the sqr root of 9 and we have [tex]3\sqrt{5}[/tex]
A clothing store is offering two coupons. one is for $50 off your purchase and the other is for 30% off your purchase. If the total before the discount is $195.42, Which of the coupons is best for you to use
A. $50 off because it gives a bigger discount
B. 30% off because it gives a bigger discount
Answer:
B.
Step-by-step explanation:
$195.42 - $50 = $145.42
$195.42/30% = 136.79

Serenity has some pennies and some nickels. She has no less than 18 coins worth at most $0.66 combined. If Serenity has 12 pennies, determine the maximum number of nickels that she could have. If there are no possible solutions, submit an empty answer.
Answer: 10 nickels
Step-by-step explanation:
A pennie is a cent or $0.01. Serenity has 12 pennies so the amount she has from pennies is:
= 12 * 0.01
= $0.12
The amount she has in nickels at most is therefore:
= 0.66 - 0.12
= $0.54
A nickel is $0.05 so the number of nickels are:
= 0.54/0.05
= 10.8 nickels
= 10 nickels
If she has 10 nickels then the total she would have is:
= (12 * 0.01) + (10 * 0.05)
= $0.62
This fits the parameters

a packet contains 6 maths books each of length 25 CM 20 cm and height 2 cm what is the volume of the packet
Step-by-step explanation:
1book valume = 25cm×20cm×2cm=1000cm³
a packet valume = 6×1000cm³ = 6000cm³
Answer:
216000 cm3
Step-by-step explanation:
length of packet = 6 × 25 cm = 150 cm
breadth of packet = 6 ×20 cm = 120 cm
height of packet = 6 × 2 cm = 12 cm
Now,
volume of packet = l×b×h = 150 cm × 120 cm × 12 cm
= 216000 cm3

Answer:
emily 37.44$ Andy 22.15$
Step-by-step explanation:
Andy needs 23 feet multiply 23 feet by 12 you get the amount of inches so 276 inches if the cost for 130 inches is 10.40 we need to increase this number proportionally to 276 So 130+113%=276.9 so 276. Now 10.40x113%=22.15.
Emily needs 13 yards, 13 yards is 39 feet, 39 feet is 468 inches, Now do same thing we did for Andy. 130+360%=468 exactly 10.40+360%=37.44

Vhat is the value of x in the equation 3x - 2y = 18, when y= 27?
Answer:
x = 24
Step-by-step explanation:
3x - 2y = 18
y = 27
3x - 2(27) = 18
3x - 54 = 18
3x = 72
x = 24
Answer:
x=24
Step-by-step explanation:
3x-2y=18
Put the y value where it belongs...
3x-2(27)=18
3x-54=18 Separate the x
+54 +54
3x=72 Divide
x=24
