find the x intercept and y intercept of
3x - 9y =18
Answer:
y-intercept: (0, -2)
x-intercept: (6, 0)
Step-by-step explanation:
The y-intercept is the value of y when x =0. Substitute 0 for x to find the y-intercept.
[tex]3x - 9y = 18[/tex]
[tex]3(0) - 9y = 18[/tex]
[tex] - 9y = 18[/tex]
[tex]y = - 2[/tex]
When x = 0, y = - 2 so the y-intercept is (0, - 2).
The x-intercept is the value of x when y = 0. Substitute 0 for y in the equation to find the x-intercept.
[tex]3x - 9y = 18[/tex]
[tex]3x - 9(0) = 18[/tex]
[tex]3x = 18[/tex]
[tex]x = 6[/tex]
When y = 0, x = 6 so the x-intercept is (6, 0).

Step-by-step explanation:
Consider the system of equations in standard form. x + 4y = 26, 3x – 4y = 30 What is the best window range for the x-values to determine the solution? What is the best window range for the y-values to determine the solution? What is the exact solution to the system of equations?
Answer: x + 4y = 26 Slope = -0.500/2.000 = -0.250
x-intercept = 26/1 = 26.00000
y-intercept = 26/4 = 13/2 = 6.50000
Step-by-step explanation: x + 4y = 26
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 6.500 and for x=2.000, the value of y is 6.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 6.000 - 6.500 = -0.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -0.500/2.000 = -0.250
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x+4y-26 = 0 and calculate its properties
Notice that when x = 0 the value of y is 13/2 so this line "cuts" the y axis at y= 6.50000
y-intercept = 26/4 = 13/2 = 6.50000
When y = 0 the value of x is 26/1 Our line therefore "cuts" the x axis at x=26.00000
x-intercept = 26/1 = 26.00000
3x – 4y = 30 Slope = 1.500/2.000 = 0.750
x-intercept = 30/3 = 10
y-intercept = 30/-4 = 15/-2 = -7.50000
Notice that when x = 0 the value of y is 15/-2 so this line "cuts" the y axis at y=-7.50000
y-intercept = 30/-4 = 15/-2 = -7.50000
y = 0 the value of x is 10/1 Our line therefore "cuts" the x axis at x=10.00000
x-intercept = 30/3 = 10
Answer:
What is the best window range for the x-values to determine the solution?
x-min=-10, x-max = 15
What is the best window range for the y-values to determine the solution?
y-min= 0, y-max = 5
What is the exact solution to the system of equations?

i can type 39 words 36 secs at this rate how many words will i type in one minute.
Answer:
65
Step-by-step explanation:
You can write it as a ratio. 39:36. You then have x:60. You can divide 36 by 60 and then divide 39 by that number (0.6)
Answer:
65 words perminute
Step-by-step explanation:
36/ 36=1
39/36= 13/12=1 1/12
1 1/12 x 60=65

Put a lid on it! The supplier is considering two changes to reduce to 1% the
percentage of its large-cup lids that are too small. One strategy is to adjust the
mean diameter of its lids. Another option is to alter the production process,
thereby decreasing the standard deviation of the lid diameters,
a. If the standard deviation remains at o = 0.02 inch, at what value should the
supplier set the mean diameter of its large-cup lids so that only 1% are too
small to fit?
b. If the mean diameter stays at = 3.98 inches, what value of the standard
deviation will result in only 1% of lids that are too small to fit?
c. Which of the two options in parts (a) and (b) do you think is preferable? Justify
your answer. (Be sure to consider the effect of these changes on the percent of
lids that are too large to fit.)
Answer:
A) 3.996 inches
B) 0.01
C) option B
Step-by-step explanation:
Note: The diameter of the lid is between : 3.95 and 4.05
A) calculate the supplier set mean diameter
std = 0.02 inch
P( x < 3.95 ) = 1% = 0.01
= P ( Z < [tex](\frac{3.95 - u }{0.02})[/tex] ) = P ( Z < -2.3263 ) = 0.01
therefore :
[tex](\frac{3.95 - u }{0.02})[/tex] = -2.3263
hence : u = 3.996 inches ( mean diameter )
B) At mean diameter = 3.98 calculate the value of std
P ( X < 3.95 ) = 0.01
= P ( Z < [tex]( \frac{3.95-3.98 }{std } )[/tex] ) = P ( Z < -2.3263 ) = 0.01
therefore
[tex]( \frac{3.95-3.98 }{std } )[/tex] = -2.3263
hence std = 0.01 inch
C) option B is preferable because its mean diameter is smaller and the percent of lids too large to fit is considered more carefully using option B

Daisy made 6 phone calls in 13 hour. At that rate, how many phone calls can she make in 1 hour?
Answer:
She can make almost 1 phone call in an hour (particularly, 46 minutes of call per hour)
Step-by-step explanation:
This problem can be solved by using ratios and proportions.
Step 1: Identify the "knowns" from the "unknown."
It is known that Daisy can make 6 phone calls in 13 hours. Now, the problem is asking for the number of phone calls Daisy can make in 1 hour.
The "unknown" here is the number of phone calls Daisy can make in 1 hour.
Step 2: The values should be plug into the proportion.
[tex]\frac{6 phone calls}{13 hours}[/tex] = [tex]\frac{x phone calls}{1 hour}[/tex]
Step 3: We can now solve the proportion.
[tex]\frac{6}{13}[/tex] = [tex]\frac{x}{1}[/tex] ⇒x = 0.46 calls per hour (almost 1 call per hour)

How do I solve for x, y, and z? Please help ASAP.
Answer:
x = 60 degrees, y = 120 degrees, z = 30 degrees
Step-by-step explanation:
To solve this problem, we must first recognize that the triangle on the left is an equilateral triangle. This means that all of its side lengths are equal, which in turn means that all of its angles have the same measure. Since we know the sum of the interior angles of a triangle must be 180, we can write and solve the following:
x + x + x = 180
3x = 180
x = 60 degrees
Next, we should notice that one of the 60 degree angles is supplementary with angle y, which means that their sum should equal 180 degrees. This lets us write the following equation:
y + 60 = 180
When we subtract 60 from both sides to solve, we get:
y = 120 degrees
Finally, we should notice that the triangle on the right is isosceles. This means that two of the side lengths (and thus two of the angles) are equal. This means that the unmarked angle must also measure z degrees since the side lengths corresponding to these two side lengths are equal. From this information we can write the following equation:
y + z + z = 180
If we substitute the value for y and solve, we get:
120 + 2z = 180
2z = 60
z = 30 degrees
Therefore, the correct answer is x = 60 degrees, y = 120 degrees, and z = 30 degrees.
Hope this helps!

how do you solve for x?
Answer: x = 6
Step-by-step explanation:
m<CAD = m<BAC
m<CAD = 4x
m<CAD + m<BAC = m<BAD
4x + 4x = 10x - 12
8x = 10x - 12
-10x -10x
-2x = -12
x = -12/-2
x = 6

Each of these is a pair of equivalent ratios, for each pair explain why they are equivalent. 5:1 and 15:3
10.2 and 25.5
198:1,287 and 2:13
Step-by-step explanation:
5:1 and 15:3 is equivalent because 5 ⋅ 3 = 15, and 1 ⋅ 3 = 3.
10.2 ⋅ 2.5 = 2.5.5 (This wasn't put into a ratio form.)
198:1,287 and 2:13 are equivalent because 198/99 = 2, and 1,287/99 = 13.

The book contains 200 thin sheets of paper.
The student wants to find the average mean, thickness of a sheet of paper in the book
Describe how he can determine such a small distance using only a ruler.
Answer:
Measure all the sheets together and divide by 200
Step-by-step explanation:
An average mean is the sum of something divided by how many things there are. In this case, it is the sum of the thickness of 200 pages, divided by the number of pages, 200.
