Answer:
[tex]\huge\boxed{\sf Solution\ Set = \{x,y\} = \{1,2\}}[/tex]
Step-by-step explanation:
3x + 4y = 11 ----------------------(1)
x = 15 - 7y ----------------------(2)
Put Eq. (2) in (1)
3(15 - 7y) + 4y = 11
45 - 21y + 4y = 11
45 - 17y = 11
Subtracting 45 to bot sides
-17y = 11 - 45
-17y = -34
Dividing both sides by -17
y = -34 / -17
y = 2
[tex]\rule[225]{225}{2}[/tex]
Put y = 2 in Eq. (2)
x = 15 - 7(2)
x = 15 - 14
x = 1
[tex]\rule[225]{225}{2}[/tex]
Solution Set = {x,y} = {1,2}
[tex]\rule[225]{225}{2}[/tex]
Hope this helped!

Given: F(x) = 2x - 1; G(x) = 3x + 2; H(x) = x^2 find the function F[G(x)]-F(x)
Answer:
4x+4
Step-by-step explanation:
F[G(x)]
=F(3x+2)
=2(3x+2)-1
=6x+4-1
=6x+3
F[G(x)]-F(x)
=6x+3-(2x-1)
=6x+3-2x+1
=4x+4
Marie is using unit cubes to build a tower in the shape of a right rectangular prism here is a description of the tower bottom layer is made up of 25 unit cubes bottom layer is in the shape of a square prism 4 more equal layers of unit cubes are added on top of the bottom layer what is the total volume in cubic units of the completed tower
Volume would be the area of the bottom times the height.
The bottom area is given as 25 and the height is given as 4
Volume would be 25 x 4 = 100 cubic units.

Service time for a customer coming through a checkout counter in a retail store is a random variable with the mean of minutes and standard deviation of minutes. Suppose that the distribution of service time is fairly close to a normal distribution. Suppose there are two counters in a store, customers in the first line and customers in the second line. Find the probability that the difference between the mean service time for the shorter line and the mean service time for the longer one is more than minutes. Assume that the service times for each customer can be regarded as independent random variables. Round your answer to two decimal places (e.g. 98.76).

Baldwin Family walked 4/5 of mile in 4/9 of an hour what is their unit rate in mph
Answer:
1.8 mphStep-by-step explanation:
Since we know how much they walked in 4/9 of an hour, we will divide 4/5 by 4/9 to get 4/9 to one. They went 1 4/5 mph or 1.8 mph. I hope this helps!Evaluate the expression 2(4+62)−20÷4 and type your answer in the box. HELP PLEASE!
Answer:
The answer would be 127
Step-by-step explanation:
4+62=66
=2\cdot \:66-20\div \:4
2\cdot \:66=132
=132-20\div \:4
20\div \:4
20\div \:4=5
=132-5
132-5=127
=127
hope this helped !
Answer:
2(4+62)-20/4
2x66-20/4
2x66-5
132-5
=127
Step-by-step explanation:
•You start with Parentheses first which is 4+62=66
•Then do division which is 20/4=5
•you put everything together 2x66-5
• Multiply 2x66=132 then subtract that by 5 and you get 127 as your final answer
Simplify 4(4a+5b-3)

f(x)=18,000(.88)^x ; x represents the number of years since the car started to depreciate and 18,000 = the initial value of the car. What year will you recieve the car when the car value drops below $2,000? Please do a step by step
Answer:
After 17 years and 3 monthsStep-by-step explanation:
Given function:
f(x)=18000(0.88)^xWe are looking for the value of x at f(x) < 2000
Solve the equation:
2000 = 18000(0.88)^x(0.88)^x = 2000/18000(0.88)^x = 0.1111log (0.88)^x = log 0.1111x = log 0.1111 / log 0.88x = 17.18After 17 years and 3 months the car value drops below $2,000
Put f(x)=2000 and solve
2000=18000(0.88)^x2=18(0.88)^x1/9=(0.88)^xln(0.111)=xln0.88x=ln(0.111)/ln0.88x=17.18Atleast 18 years
You will recieve in 18the year going on

A person invests 9000 dollars in a bank. The bank pays 4.75% interest compounded quarterly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 12600 dollars?
7.1 years
Step-by-step explanation:
Principle P = 9000 dollars
Rate r = 4.75% = 0.0475
Total Amount A = 12600 dollars
compounded quarterly n = 4
Time t = ?
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(12,600/9,000) / ( 4 × [ln(1 + 0.011875/4)] )
t = 7.1 years
so the answer is 7.1 years
