4.) solve for f(g(2))
Answer:
[tex]f(g(2))=10[/tex]
Step-by-step explanation:
We have the two functions: [tex]f(x)=3x-5[/tex] and [tex]g(x)=2+\frac{6}{x}[/tex].
We want to find [tex]f(g(2))[/tex].
So, let's use the second function to find [tex]g(2)[/tex] first:
[tex]g(2)=2+\frac{6}{2}[/tex]
Divide:
[tex]g(2)=2+3[/tex]
Add:
[tex]g(2)=5[/tex]
Therefore, our expression is the same to [tex]f(g(2))=f(5)[/tex].
Now, we can substitute 5 for f(x). This yields:
[tex]f(5)=3(5)-5[/tex]
Multiply:
[tex]f(5)=15-5[/tex]
Subtract:
[tex]f(5)=10[/tex]
So:
[tex]f(g(2))=10[/tex]
And we're done!

The cost of an Uber ride can be modled by y = 3x + 5, where x is the number of miles driven. You paid $44 in a
cab fare, how many miles did you drive?
Answer:
13
Step-by-step explanation:
44=3x+5
44-5=39
39/3=13
Answer:
13 miles driven
Step-by-step explanation:
y = 3x + 5
Y is the amount we paid, so we insert 44 into the equation.
44 = 3x + 5
Any thing you do to one side of the equation, you do to the other side, so -5 from both sides.
44-5 = 39
5-5 = 0
So you are left with:
39 = 3x + 0 (So you can ignore the 0)
Like I said earlier, anything you do to one side of the equation you do to the other so divide both sides by 3:
39 divided by 3 = 13
3 divided by 3 = 1
So now you have:
13 = 1x
So x = 13 and that is how many miles you drove.
If this is confusing let me know

Logan earned $8
for each dog he walked last summer. This summer, he raised his fee to $9
per dog. Express the change in Logan’s fees as a percent. Round to the nearest tenth of a percent
Answer: 11.11%
Step-by-step explanation: Since he earned 8 dollars for each dog last summer, and he now raised it to 9 dollars per dog, we can make the subtract 9/9 - 8/9, which would equal 1/9. 1 is 11.111% of 9, so that's the answer.
The length of a rectangle is 3 inches more than it’s width. if the perimeter is 42 inches, find the dimensions of the rectangle
Answer:
Length = 9 in Width = 12 inStep-by-step explanation:
Length L = 3 + W
Perimeter P = 42 in
Perimeter = 2L + 2W
plugin values:
42 = 2(3 + W) + 2W
42 = 6 + 2W + 2W
42-6 = 4W
W = 36 / 4
W = 9
solve L by substituting the value of W=9 into the equation:
L = 3 + W
L = 3 + 9
L = 12
therefore, the dimensions of the rectangle:
Length = 9 in
Width = 12 in
The dimensions for the rectangle are 12 in and 9 in if the length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches.
What is rectangle?It is defined as the two-dimensional geometry in which the angle between the adjacent sides are 90 degree. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
It is given that:
The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches.
Let l be the length and w be the width of the rectangle.
Length l = 3 + w
Perimeter P = 42 in
Perimeter = 2l + 2w
42 = 2(3 + w) + 2w
w = 36/4
w = 9 in
solve for l by substituting the value of w = 9 into the equation:
l = 3 + w
l = 3 + 9
l = 12 in
Thus, the dimensions for the rectangle are 12 in and 9 in if the length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches.

Step-by-step explanation:

Venn diagrams gives a visual representation of the distribution of a whole divided into two or more groups using circles. Going by the scale of the Venn diagram given, only the inequalities A, C, E and F must always be true.
Size of brown hair = H
Size of brown eyes = E
Size of those who have both = X
From the Venn diagram given ; we can deduce that H = E
Evaluating the inequalities :
H ≥ E is True because H = E H ≥ X is True because proportion of H is more than X H > X is True because proportion of H is more than X H + 10 ≥ E is must not always be True because H = E ; adding 10 more to H will make H more than E always. H + 10 ≥ X is False because proportion of H is more than X, adding 10 more to H, the proportion gets bigger H + 10 > X is True because proportion of H is more than XTherefore, only the inequalities A, C, E and F must always be true.

What is the solution to the system of equations graphed below?
==================================================
The graphs cross at this point. Intersection points are solutions to systems of equations.
Put another way, (1,4) is on the blue line and on the red line simultaneously.
A point on the red line is a solution to the red equation. A point on the blue line is a solution to the blue equation.
-----------------
Checking the answer:
y = x+3
4 = 1+3 ... plug in x = 1 and y = 4 into the blue equation
4 = 4 .... solution works for the blue equation
y = 3x+1
4 = 3(1)+1 ... plug in x = 1 and y = 4 into the red equation
4 = 3+1
4 = 4 ... solution also works for the red equation
This fully confirms the solution

Car A is traveling east at a steady speed of 60 miles per hour after 2 hours, it is 130 miles east of Johnstown. car B is traveling east on the same road. its distance east of Johnstown is represented by the graph.
Please help!
Answer: A
Step-by-step explanation:
Car B was 10 miles east of car A.
What is speed?The rate of change of position of an object in any direction is called speed.
What is the relation between speed, distance and time?[tex]speed = \frac{distance}{time}[/tex]
According to the given question
Speed of car A was 60 miles/hour.
⇒ After 2hours the distance covered by car A = 60 × 2 = 120 miles.
But it is given that car travelled total 130 miles.
So, the extra distance covered by the car = 130 - 120 = 10 miles.
From the graph we can say that the distance.
At, Time = 0
The distance travelled by car B is 20 miles.
Now, the extra distance covered by the car A w.r.t B = 20 - 10 = 10 miles
Since, both the cars were travelling in east direction.
Therefore, Car B was 10 miles east of car A.
