To answer this question we will set the equation y=f(x), then we will solve the equation for x, and finally, we will exchange x and y.
Setting y=f(x) we get:
[tex]y=\frac{3}{4}x+12.[/tex]Subtracting 12 from the above equation we get:
[tex]\begin{gathered} y-12=\frac{3}{4}x+12-12, \\ y-12=\frac{3}{4}x\text{.} \end{gathered}[/tex]Multiplying the above equation by 4/3 we get:
[tex]\begin{gathered} (y-12)\times\frac{4}{3}=\frac{3}{4}x\times\frac{4}{3}, \\ x=\frac{4}{3}y-16. \end{gathered}[/tex]Exchanging x and y in the above equation we get:

The equation of line is y = 8/5x-26/5.
What is a line equation?
A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.
Equation 8x-5y=4 is given.
-5y = 4-8x
y = 8/5x-4/5 and we are aware that the line's equation is y = mx+b
m = 8/5
Nowadays, coordinates are (2,-2)
Y=-2, X=2, and m=8/5
y = mx+c
-2 = 8/5(2)+c
c = -26/5

Josh is mountain climbing with Kendall and has just climbed a 6-meter vertical rock face. Kendall is standing 8 meters away from the bottom of the cliff, looking up at Josh. How far away are Josh and Kendall?
Answers
Josh and Kendall are 10m far away from each other.
Josh is mountain climbing with Kendall and has just climbed a 6-meter vertical rock face.
Kendall is standing 8 meters away from the bottom of the cliff
As he climbed a vertical rock face the, the angle formed between the rock and the ground is 90.
Josh climbed 6 meter vertical rock, so perpendicular is 6m
Kendall is standing 8 meters away from the bottom of the cliff, base = 8m
So, here pythagoras theorem is used here to find the distance between Josh and kendall
As per pythagoras theorem,
h² = b² + p²
= 8² + 6²
= 64 + 36
h² = 100
h = √100 = 10
Therefore the distance between Josh and Kendall is 10m.

Tammy drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 7 hours. When Tammy drove home, there was no traffic and the trip only took 5 hours. If her average rate was 18 miles per hour faster on the trip home, how far away does Tammy live from the mountains?
Answers
ANSWER
[tex]\begin{equation*} 315\text{ }miles \end{equation*}[/tex]EXPLANATION
Let her average rate on the trip to the mountains be x miles per hour.
This implies that her average rate on her way home was (x + 18) miles per hour.
The distance traveled can be found using the formula for speed(average rate):
[tex]\begin{gathered} speed=\frac{distance}{time} \\ \\ distance=speed*time \end{gathered}[/tex]Therefore, on her way to the mountains:
[tex]d=x*7[/tex]And on her way home:
[tex]d=(x+18)*5[/tex]Since the distance is the same for both trips, equate the two equations:
[tex]\begin{gathered} x*7=(x+18)*5 \\ \\ 7x=5x+90 \end{gathered}[/tex]Solve for x in the equation:
[tex]\begin{gathered} 7x-5x=90 \\ \\ 2x=90 \\ \\ x=\frac{90}{2} \\ \\ x=45\text{ mph} \end{gathered}[/tex]Substitute the value of x into the equation for distance to find the distance:
[tex]\begin{gathered} d=45*7 \\ \\ d=315\text{ }miles \end{gathered}[/tex]That is the distance from the mountains to where Tammy lives.

Answers
From the standard normal tables, we have the value of

P(z=0) = 0.5000
Therefore the area between z = 0 and z = 0.8 under the standard curve is,
P(z=0.8) - P(z=0) = 0.7881 - 0.5000

The rate of growth dPdt of a population of bacteria is proportional to the square root of t with a constant coefficient of 9, where P is the population size and t is the time in days (0≤t≤10). The initial size of the population is 600. Approximate the population after 7 days. Round the answer to the nearest integer.

To solve this question we are going to need to define an equation with the data that the problem gives us
The first part (rate of growth) shows us a derivate, this is equal to 9 square root of t or:
[tex]\frac{dP(t)}{dt}=9\sqrt{t}[/tex]where P is the population size and t is the time in days
Now we need the population after 7 days, so we need the P(t) formula, which means that we need the integration
First, we send the dt to the other side to have something to integrate
[tex]\int dP(t)=\int9\sqrt{t}dt[/tex]Solving
[tex]\begin{gathered} P(t)=9(\frac{2}{3}t^{\frac{3}{2}})+C \\ \\ P(t)=6t^{\frac{3}{2}}+C \end{gathered}[/tex]We know that P(0)=600 so
[tex]P(0)=600=C[/tex][tex]P(t)=6t^{\frac{3}{2}}+600[/tex]Now we replace the t by 7

Answers
The y-intercept of the equation y = 3x − 2 is (0, -2).
y-intercept
In Mathematics, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx + c, where m is slope and c is the y-intercept.
Equation of a line
The standard form of equation of a line is ax + by + c = 0. Here a, b, are the coefficients, x, y are the variables, and c is the constant term. It is an equation of degree one, with variables x and y. The values of x and y represent the coordinates of the point on the line represented in the coordinate plane.
Given that lies on the graph of the equation y = 3x − 2.

Write an equation to that can be used to determine B. What is the flat rate of the cab ride? C. How much does it cost to travel 7 miles in a cab?
Answers
The total distance from Washington DC to Dulles airport is 15 miles
The total cost of the cab ride is $25. 50
The cabbie charges $1.50 per mile for the entire trip
Let T be the total cost of the entire trip
Let x represents the number of miles traveled
Let y be the flat rate of the cab ride
Total cost = flat rate + charge per trip x number of miles covered
Mathematically,
T = y + 1.5 * x
T = y + 1.5x
Where, 1.5 is the charge per trip.
The equation becomes
T = y + 1.5x
B
To calculate the flat rate of the cab ride?
The total cost = $25.50
Charges per mile = $1.5
Total number of miles = 15
Substitute the above values into the equation
25.50 = y + 1.5 x 15
25.50 = y + 22.5
Make y the subject of the formula
y = 25.50 - 22.5
Y = $3
The flat rate of the cab ride is $3
