Step-by-step explanation:
5 nights
The family have to stay 5 nights in order to cost the same amount of money.
Function in one variable:Let us consider that family is staying for x night.
Given that, Option A costs $479 per night and includes airfare in the cost.
So that, [tex]A(x)=479x[/tex]
Also Option B costs $129 per night but will cost your family $1750 in airfare.
So that, [tex]B(x)=129x+1750[/tex]
for the cost of same amount of money,
[tex]A(x)=B(x)\\\\479x=129x+1750\\\\479x-129x=1750\\\\350x=1750\\\\x=1750/350=5[/tex]
The family have to stay 5 nights in order to cost the same amount of money.

Question 3

If JL = 9x - 5, LR = 7x - 2, and JR = 35, find JL. Round your answer to the nearest tenth.
Answer:
JL = 166 units
Step-by-step explanation:
Given that,
JL = 9x - 5, LR = 7x - 2, and JR = 35
Let us assume that, R is the midpoint of J and L. So,
JL = JR + RL
Putting all the values,
9x - 5 =35 + 7x - 2
Taking like terms together as follows :
9x-7x = 33 + 5
2x = 38
x = 19
Put the value of x inm, JL = 9x-5
JL = 9(19)-5
JL = 166
The value of JL is 166 units.

Answer:
[tex]\boxed{\bold{\huge{\boxed{x = 10}}}}[/tex]
Step-by-step explanation:
=> [tex]\sf \frac{3}{4} x + \frac{5}{6} = 5x - \frac{125}{3}[/tex]
Combining like terms
=> [tex]\sf \frac{3x}{4} - 5x = -\frac{125}{3} - \frac{5}{6}[/tex]
Taking LCM to make the denominator same
=> [tex]\sf \large{\frac{3x-20x}{4} = \frac{-250-5}{6} }[/tex]
=> [tex]\sf \frac{-17x }{4} = \frac{-255}{6}[/tex]
=> [tex]\sf \frac{17x }{4} = \frac{255}{6}[/tex]
Cross Multiplying
=> [tex]\sf 17x * 6 = 4 * 255[/tex]
=> [tex]\sf 102x = 1020[/tex]
Dividing both sides by 102
=> x = 10

Please Please help! I am so beyond stuck. I have figured out what is wrong with the first step but I cant figure out what is going on with the second one!
Answer:
[tex]x<-\frac{1}{2}\text{ or } x>1[/tex]
Step-by-step explanation:
So we have the equation:
[tex]|-4x+1|>3[/tex]
First, note that since the sign is greater than, this is an or inequality (not an "and" inequality). This is the student's first mistake.
So, let's solve this inequality.
Case 1:
[tex]-4x+1>3[/tex]
Subtract 1 from both sides:
[tex]-4x>2[/tex]
Divide both sides by -4:
[tex]x<-\frac{1}{2}[/tex]
The student did not flip the sign when doing this step, hence the incorrect answer.
You correctly spotted the student's mistake. Nicely done!
Case 2:
[tex]-4x+1<-3[/tex]
This is what you're missing: for this second instance, we must flip the sign to less than right away. This is because we are essentially multiplying the 3 by a negative. So, we must flip the sign in order to be correct.
Now solve. Subtract 1 from both sides:
[tex]-4x<-4[/tex]
Divide both sides by -4. Since we're dividing by a negative, flip the sign:
[tex]x>1[/tex]
So, our solutions are:
[tex]x<-\frac{1}{2}, x>1[/tex]
As mentioned previously, this is an or inequality. Therefore, our final answer is:
[tex]x<-\frac{1}{2}\text{ or } x>1[/tex]

Determine the number of degrees for the angle in section B of the pie chart . Round to the nearest whole degree Please assist me
Answer:
115°
Step-by-step explanation:
Measure of the degree of the angle represented by section B on the chart = percentage in the pie chart ÷ 100 × 360. A full circle makes 360°.
Section B represents 32% of the pie chart, therefore, number of degrees for section B = [tex] \frac{32}{100}*360 = \frac{32*360}{100} [/tex]
[tex] = 115.2 [/tex]
Section B = 115° (to the nearest whole number)
h(x)=x^2+1 k(x)=x-2
(h+k)(2)=
(h-k)(3)=
Evaluate 3h(2)+2k(3)=
(h + k)(2) = 5
(h - k)(3) = 9
evaluate 3h(2) + 2k(3) = 17
The composition of functions is solved
a) ( h + k ) ( 2 ) = 5
b) ( h - k ) ( 3 ) = 9
c) 3h ( 2 ) + 2k ( 3 ) = 17
What is Composition of functions?Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the first function be represented as f ( x )
Now , the value of f ( x ) is
h ( x ) = x² + 1
Let the second function be represented as g ( x )
Now , the value of g ( x ) is
k ( x ) = x - 2
Now , the composition of function is
To calculate (h+k)(2), we substitute x = 2 in both h(x) and k(x), add them together and simplify:
h(2) = 2² + 1 = 5
k(2) = 2 - 2 = 0
(h+k)(2) = h(2) + k(2) = 5 + 0 = 5
To calculate (h-k)(3), we substitute x = 3 in both h(x) and k(x), subtract k(x) from h(x), and simplify:
h(3) = 3² + 1 = 10
k(3) = 3 - 2 = 1
(h-k)(3) = h(3) - k(3) = 10 - 1 = 9
To evaluate 3h(2)+2k(3), we substitute x = 2 and x = 3 in h(x) and k(x), respectively, and simplify:
3h(2) + 2k(3) = 3(5) + 2(3-2) = 15 + 2 = 17
Therefore , ( h + k ) ( 2 ) = 5 , ( h - k ) ( 3 ) = 9, and 3h( 2 ) + 2k( 3 ) = 17
Hence , the composition of functions is solved

Jaquarius has a pair of limited edition Jordan tennis shoes that are 12 inches long each. What is the total length of both of his shoes in feet?
Answer:
Total length of shoes in feet = 2 feet
Length of each shoe = 1 feet
Step-by-step explanation:
Given:
Length of each shoe = 12 inches
Find:
Total length of shoes in feet
Computation:
Total length of shoes = [12 + 12] inches
Total length of shoes = 24 inches
12 inches = 1 feet
Total length of shoes in feet = 24 / 12
Total length of shoes in feet = 2 feet
Length of each shoe = 1 feet
At the beginning of a snowstorm, Sydney had 11 inches of snow on her lawn. The
snow then began to fall at a constant rate of 0.5 inches per hour. Assuming no snow
was melting, how much snow would Sydney have on her lawn 3 hours after the snow
began to fall? How much snow would Sydney have on her lawn after t hours of snow
Answer:
12.5in.
x=.5t+11
Step-by-step explanation:
First of all, create the equation so you can solve both questions at once. We know that Sydney had eleven inches of snow on her lawn, and it doesn't dissapear, so it starts with x=11. Then every hour she gets .5 inches per hour, and the amount of hours is t, so that will translate to .5t. that makes the equation x=.5t+11. To find out how much she would have in three hours, substitute 3 for t, which which goes like this: x=.5(3)+11
x=1.5+11
x=12.5
Answer:
Snow after 3 hours: 12.5
Snow after t hours: 11+0.5t
What is the equation of the line that passes through the point (-2,-2) and
has a slope of 42
Answer:
The answer is
[tex]y = 42x + 82[/tex]Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (-2,-2) and slope 42
The equation of the line is
[tex]y + 2 = 42(x + 2) \\ y + 2 = 42x + 84 \\ y = 42x + 84 - 2[/tex]
We have the final answer as
[tex]y = 42x + 82[/tex]
