he general equation of a line is y = mx+b
m is the slope of the line that you can figure out using the equation: m = (y2-y1)/(x2-x1)
m = (4-2)/(4-1) = 2/3
y = 2/3x+b and you can use either point given to find b:
1) 4 = 2/3(4)+b => b = 4-8/3 = 4/3
2) 2 = 2/3(1)+b => b = 2-2/3 = 4/3
The equation becomes: y = 2/3 x + 4/3

Answer:
<UOX and <YOZ
Step-by-step explanation:
Adjacent angles are angles that share a common side and vertex. So, find the angles that share one side. In this case, the two sides of the angle <XOY are OX and YO. Remember when naming an angle that it should be one side, the vertex, the last side. So, the 2 adjacent angles are <UOX and <YOZ because they each share one common side and vertex.

arrange the equation according to general formula;
General formula: ax² + bx + c = 0
therefore:

Using the quadratic equation :

a » 1, b » 5, c » 2
substitute:

The domain of g(x) is the set of all real numbers. Also, g(g(x)) is defined for the set of all real numbers. Therefore, the domain of is the set of gg D all real numbers
Step-by-step explanation:
Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited
Hey, can someone help me with 8 math problems of numbers in their prime factored form? I have no idea how to do this and my teacher didn't really explain very well, so this would be a big help!
Answers
Prime factorization is shows you the only way a number can be factored.
Here are some examples:
6 = 2 x 3
(2 and 3 are prime numbers) If you need to, search up a prime chart of numbers. Also prime numbers is technically how small you can get a number.
Here are some more examples:
12 = 2 x 2 x 3
45 = 5 x 3 x 3
now that you see what it looks like, you may be wondering how did factor those out? Well first find a divisible number. lets use this example;
Factor out 42.
first think of your times table, what two numbers get you to 42, I know that 6 times 7 does so now write it out:
42 = 6 x 7
Is this equation done?
No it is not, 6 can still be factored.
What two numbers get you the product of 6?
they are 3 and 2.
Now the final factored out equation looks like this:
42 = 3 x 2 x 7

[tex]{ \sf{ \underline{answer \: is \: \: 6 \frac{7}{20} }}}[/tex]
Step-by-step explanation:
Hope you got the idea in previous answer.
[tex]6.350 = \frac{6350}{1000} [/tex]
reduce the fraction by 10:
[tex] = \frac{6350 \div 10}{1000 \div 10} \\ \\ = \frac{635}{100} [/tex]
then reduce it by 5:
[tex] = \frac{635 \div 5}{100 \div 5} \\ \\ = \frac{127}{20} [/tex]
in mixed fraction mode:
[tex] = 6 \frac{7}{20} [/tex]
Working alone, Dan can paint a fence in ten hours. One day his friend Natalie helped him and it only took 4.12
hours. How long would it take Natalie to do it alone?
Answers
===========================================================
Explanation:
Let's say there are 1000 boards to be painted.
Working alone, Dan can paint 1000 boards in 10 hours, so his unit rate is 1000/10 = 100 boards per hour.
In 4.12 hours, he gets 4.12*100 = 412 boards painted. There are 1000-412 = 588 boards left which Natalie takes care of. This is when the two are working together.
Her unit rate is (588 boards)/(4.12 hours) = 142.718447 boards per hour. That value is approximate.
We multiply her unit rate by some unknown amount of time x, and this product will be the 1000 boards we started with. This way she would get the job down by herself.
So the equation we need to solve is
142.718447x = 1000
--------------------
We divide both sides by 142.718447 to fully isolate x.
142.718447x = 1000
x = 1000/(142.718447)
x = 7.006803
That value is approximate.
If we round to the nearest whole number, then x = 7
So it takes about 7 hours for Natalie to get the job done if she works alone.
-------------------

Find the value of x, given that mangle PQS = 110°.
Round the answer to one decimal place if necessary.
72+10x
(gotta find value for X)
Answers
(value of x)
So the answer is 90.8°
The correct answer would be 88.5° because 72 + 10X = 90 + X and then you have to subtract that from 110 degrees. (110 - 90 = 20, 20 / 2 = 10, so you add 10 to both sides of the equation)
110-90=20
20/2=10
10+X=10
X=0.5°
110-90+0.5 = 20.5 and that answer is rounded up to 21°
(The reason it is not rounded down to 20° is because 10/2 is 5 but you don't add it to 10 so it would be rounded down)
So the answer is 88.5°
X=88.5 ° Note: "That" in that mangle PQS = 110 ° does not refer to the answer x and therefore should be omitted. Example: Given mangle PQS = 110 °, find the value of x.
Answer: 90.8° (rounded up to the nearest degree)
Note: In free response questions, typically one decimal place is needed in the answer even if no decimal places are given in the question. For example, 1/3 is 0.33333..., and the answer is 0.3 (not 0).
88.5° should be rounded up to 90° because you add 72 + 10x which equals 90 + x and then you subtract that from 110 degrees which gives you 20 degrees. Then 20/2 = 10 so that's when you add 10 to both sides. 110 - 90 + 0.5 equals 20.5 but since 10/2 is 5 and you add that to 10 so it's now 29.5 which means you have to subtract 15 from both sides of the equation (since you can't subtract half a degree) which leaves you with 14.5 degrees, which rounds up to 15 degrees. So the answer is 88.5°.
So the correct answer should be 90°

then -1 (7) < 7x < 7(4)
- 7 < 7x < 28
-7 + 4 < 7x + 4 < 28 + 4
-3 < 7x + 4 < 32
SInce all the options are within the range between -3 and 32 then the answer is 1.
