To find the x-intercept, we let y = 0 and solve for x and to find y-intercept, we let x=0 and solve for y. Figure out the x-intercept and y-intercept in given equation of the line.
6x + 2y = 12
Answer:
x-intercept = 2
y-intercept = 6
Step-by-step explanation:
x-intercept: 6x = 12; x = 2
y-intercept: 2y = 12; y = 6

The width of a rectangle is 4 feet and the diagonal length of he rectangle is 13 feet what is the measurement is the closest to the length of the rectangle in feet
Answer:
The length is APPROXIMATELY equal to 12.4.
Step-by-step explanation:
Use the converse of the Pythagorean Theorem ([tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex] [where "c" is both the longest side and the hypotenuse]) since a rectangle's diagonals will always cut it into two right triangles:
[tex]13^{2} = 169[/tex]
[tex]4^{2} =16[/tex]
169-16=153.
[tex]\sqrt{153}[/tex] ≈ 12
or
[tex]\sqrt{153}=12.36931688[/tex]
or if the problem has to be exact (using radicals)
3*[tex]\sqrt{17}[/tex]
I hope this helps ;)

Answer:
Slope is -5/3
Step-by-step explanation: when you look at the graph, the line is descending meaning it will be a negative, so we can eliminate the answers that are positive leaving us with 2 options. Then we have to do rise/run, you figure that out by counting how many points the line goes up and to the right or left, and intersects with the line

Answer:
2/11
Step-by-step explanation:
Let's say x = 0.18181818..
Then, 100x = 18.1818181....
so, if you put x in the repeating decimal in 18.1818,
you get the equation,
100x = 18+x
so, 99x = 18
x = 18/99 = 2/11
Answer:
18/100 = 9/50
Answer is 9/50

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter...This shows that hydrogen has been conserved throughout the entire process as the product has the same amount of hydrogen as the reactants.
Denira needs to run 9 4/10 miles this week to meet her goal for her training plan. So far this week she has run 3 1/2 miles on Monday and 2 1/2 miles on Tuesday. How many more miles does she need to run this week in order to meet her goal
Answer:
3 2/5
Step-by-step explanation:
Add the distance she already ran, and subtract the sum from the total she needs to run.
Add two distances she ran:
3 1/2 + 2 1/2 = 3 + 2 + 1/2 + 1/2 = 5 + 1 = 6
Subtract sum from total:
9 4/10 - 6 = 3 4/10 = 3 2/5
Answer:
She needs to run 3 4/10 more miles
Step-by-step explanation:
If you add the amount she ran on Monday and the amount she ran on Tuesday you get 6 miles then subtract the 6 miles minus 9 4/10 you will get 3 4/10.

Which of the following best describes the vertical cross-section of the cylinder ?
A.
cone
B.
rectangle
C.
triangle
D.
circle
The shape that best describes the vertical cross-section of the cylinder is given by: Option B: Rectangle.
What is a vertical cross section?When you slice a given object vertically (perpendicular to the ground level), then the sliced surface is called vertical cross section.
For a cylinder, usually it sits on its base and we take a right circular cylinder. When we slice it vertically, we obtain a rectangle, as shown in the figure attached below.
It can be proven that this shape is always going to be rectangular.
Thus, the shape that best describes the vertical cross-section of the cylinder is given by: Option B: Rectangle.

The mean, median, and mode of the given monthly salary is 1794, 1790, and 1940, respectively.
What is the measure of central tendency?Measures of central tendency assist in the discovery of a data set's middle, or average. The mode, median, and mean are the three most popular metrics of central tendency.
Mode: It is the most common value in a given data set.
Median: In an ordered data set, the median is the number in the middle.
Mean: It is the total number of values divided by the sum of all values.
For the given data, the mean, median and the mode of the data can be found as shown below,
Sum of the Observations
= 1940 + 1660 + 1860 + 2100 + 1720 + 1540 + 1760 + 1940 + 1820 + 1600
= 17940
Number of Observations = 10
The mean of the data is,
Mean = Sum of Observations / Number of Observations
= 17940 / 10
= 1794
The median of the data can be found by arranging the data in an order first. Therefore, the data can be arranged as,
1540160016601720176018201860194019402100The median of the data is,
Median = (Sum of the two mid values) / 2
= (1760 + 1820) / 2
= 1790
The mode of the data is 1940, since this is repeated twice.
b.
If the salary of each employee is increased by 5% that means that the value of each observation in the data will increase by 5%. Therefore, The raise increases the mean, median, and mode by 5% each.
c.
As it is now required to find the mean, median, and mode of the annual salary; there is a need to multiply the monthly salary of each employee by 12. Therefore, the value of each observation will be 12 times its original value. These values are 12 times the mean median, and mode of the monthly salaries.

Show your work or explain your answer. Round your final answer to the nearest tenth of a foot. Enter your model, your answer, and your work or explanations in the space provided.
Answer:5.7
Step-by-step explanation:
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The distance between the point Q and the ground is h-[L cos(80°)].
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The Base is the adjacent smaller side of the angle θ.
Let the height of the support be h and the height between the point q and the ground is x. Also, the distance between point Q and the support of the seesaw is L.
Now if we look at the ΔQAR, the measure of the ∠QRA is 80°, therefore, the sine of ∠QRA can be written as,
[tex]\rm Cos(\theta)=\dfrac{Base}{Perpendicular}\\\\Cos(\angle QRA) = \dfrac{AR}{QR}\\\\Cos(\angle QRA) = \dfrac{h-x}{L}\\\\L \times Cos(80^o)=h-x\\\\x=h-[L\ Cos(80^o)][/tex]
Hence, the distance between the point Q and the ground is h-[L cos(80°)].
