The x-intercept and the y-intercept of the line described by the equation 3x - 9y = 10.8 are 3.6 and -1.2
The x-intercept of a line is the point where y-coordinate is zero while the y-intercept of the line is the point where the x-coordinate is zero
Given the expression 3x - 9y = 10.8
Get the x-intercept. If y = 0
3x - 9(0) = 10.8
3x = 10.8
x = 10.8/3
x = 3.6
Get the y-intercept. If x = 0
3(0) - 9y = 10.8
-9y = 10.8
y = -10.8/9
y = -1.2
Hence the x-intercept and the y-intercept of the line described by the equation 3x - 9y = 10.8 are 3.6 and -1.2

His average percentile is 72%
A student passed 60 percent out of 20 quizzes50 quizzes in a year and passed 80 percent of the remaining quizzesThe success rate for all his quizzes for the entire year is unknown.Further ExplanationA student passed 60 percent out of 20 quizzes, which can be expressed as
[tex]\frac{60}{100}[/tex] x [tex]20[/tex]
[tex]60[/tex] x [tex]\frac{20}{100}[/tex]
[tex]\frac{1200}{100}[/tex]
[tex]12[/tex]
Therefore the remaining quizzes will be:
[tex]50[/tex] - [tex]20[/tex]
[tex]30[/tex] quizzes
Also, we have to determine the 80% of 30 quizzes, which can also be expressed as
[tex]\frac{80}{100}[/tex] x [tex]30[/tex]
[tex]80[/tex] x [tex]\frac{30}{100}[/tex]
[tex]\frac{2400}{100}[/tex]
[tex]24[/tex]
To find the total remaining quizzes, then we have to add both value together
Therefore, we have
[tex]30[/tex] + [tex]24[/tex]
[tex]36[/tex]
Thus, the total remaining quizzes is 36.
Now, if the student writes 50 quizzes during the year, his average percentile would be:
[tex]\frac{36}{50}[/tex] x [tex]100%[/tex]
[tex]0.72[/tex] x [tex]100%[/tex]

(x – 3)2 + (y – 5)2 = 6
(x – 3)2 + (y – 5)2 = 36
(x + 3)2 + (y + 5)2 = 6
(x + 3)2 + (y + 5)2 = 36
Answer:
Option D. (x + 3)² + (y + 5)² = 36
Step-by-step explanation:
We have to find the equation of a circle given with a center at (-3, -5) and radius of 6.
Since the standard equation of a circle is
[tex](x -h)^{2}+(y-k)^{2}=r^{2}[/tex]
where (h, k) is the center and r is the radius.

A plane that carries mail makes a round trip each day from Chicago to New York. It makes 3 intermediate stops on the way to New York and 1 intermediate stops on the way back to Chicago. Suppose you make a graph on the altitude of the plane for one day, whit time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?
Answer:
7
Step-by-step explanation:
The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.
Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.
Next, when the plane lands in New York the altitude will touch the horizontal axis.
Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.
Lastly the altitude will touch the axis when plane lands back in Chicago.
So, cumulatively the altitude will touch the horizontal axis seven times.
The altitude vs time graph for the plane's journey will touch the horizontal axis 6 times - at each landing during the round trip from Chicago to New York and back.
Explanation:The graph of the plane's altitude versus time will touch the horizontal axis each time the plane lands. The plane lands at the 3 intermediate stops on the way to New York, once in New York, at the 1 intermediate stop on the way back, and once back in Chicago. This totals up to 6 times. Skyward journeys will create upward curves on the graph while the landings create points where the graph touches the horizontal axis (indicating an altitude of 0 at landing).

Joe painted 1/4 of a bedroom in 1/2 a day. How many days will it take for Joe to paint one bedroom?
Final answer:
Joe painted a quarter of a bedroom in half a day, so it would take him 2 days to paint the entire bedroom.
Explanation:
If Joe painted ¼ of a bedroom in ½ a day, we can determine that to paint the entire bedroom, it would take four times as long since a full bedroom is four times as much as one quarter. Multiplying ½ day by 4, we get:
½ day * 4 = 2 days
Therefore, it will take Joe 2 days to paint the whole bedroom. Understanding the proportionality between the fraction of work completed and the time required enables accurate estimation of the total time needed for a task.
This logical approach simplifies complex problems and aids in efficient planning and resource management.

fg-9h=10j solve for g
It should be noted that when g is made the subject of the formula in fg - 9h = 10j, g will be g = (10j - 9h) / f.
How to illustrate the information?It should be noted that an equation is used to show the relationship that exist between the variables that are illustrated.
Based on the information, it should be noted that we want to make g the subject of the formula. This will be illustrated as:
fg - 9h = 10j
Add 9 h to both sides
fg - 9h + 9h = 10j - 9h.
fg = 10j - 9h.
Divide through by f
fg / f = (10j - 9h) / f
g = (10j - 9h) / f
In this case, it should be noted that when g is made the subject of the formula in fg - 9h = 10j, g will be g = (10j - 9h) / f.

Answer: The correct option is C. The domain of [tex](b\circ a)(x)[/tex] is [tex][0,\infty)[/tex].
Explanation:
It is given that,
[tex]a(x)=3x+1[/tex]
[tex]b(x)=\sqrt{x-4}[/tex]
First we have to find the composite function [tex](b\circ a)(x)[/tex].
[tex](b\circ a)(x)=b(a(x))[/tex]
[tex](b\circ a)(x)=b(3x+1)[/tex]
[tex](b\circ a)(x)=\sqrt{3x+1-4}[/tex]
[tex](b\circ a)(x)=\sqrt{3x-3}[/tex]
We know that a root function is defined for only positive values therefore the composite function is defined if,
[tex]3x-3\geq 0[/tex]
[tex]3x\geq 3[/tex]
[tex]x\geq 1[/tex]
The function is defined for all the values of x which are greater than or equal to 1. Therefore the domain of [tex](b\circ a)(x)[/tex] is [tex][0,\infty)[/tex] and option C is correct.
