Answer:
Step-by-step explanation:
(-1,5) (0,2)
y2= 2, y1 = 5, x2 = 0, x1 = -1
Slope m = [y2 - y1]/[x2 - x1]
m = {2 - 5}/{0+1}
m = -3/1
m = -3
And
y - y1 = m(x - x1)
y - 5 = -3(x + 1)
y - 5 = -3x - 3
y = -3x - 3 + 5
y = -3x + 2
Answer:
1
Step-by-step explanation:
If you put in 12 for t, you might see what to do.
5 - 12 / 3
12 divided by 3 = 4
/ means divide
5 - 4 = 1
Answer:
-87
Step-by-step explanation:
So, first to find <em>x</em> you need to subtract 121 from 180. You do this because both the angle which measures 121 degrees and <em>x</em> lie on the same line, and since a line has an angle measure of 180, you do 180-121 to find <em>x</em>. The same thing can be done for <em>y</em>. Since the angle measure of 34 degrees and y lie on the same line you can calculate 180-34 to get <em>y. </em>So, let's do that.
180-121=x
59=x
180-34=y
146=y
Once you've done that you can easily subtract the two and get your answer.
x-y
substitute the answer for the variables and get
59-146
and then your answer is
-87
Answer:
To simplify the ratio, you can put it into a fraction and divide both the numerator and the denominator
Both numbers can be divided by 7
21/7= 3
35/7= 5

Answer:
1. 1/2(x - 3)³
2. 3x/y²
Step-by-step explanation:
1. to simplify, we could just FOIL the equations out, but since this is a division, we can cancel out any common factors in the numerator and the denominator to make it easier
2(x - 3)³
----------
4(x- 3)^6
what do these two have in common? both have a (x - 3)³ to start off, so we can cancel out the (x - 3)³ in the numerator, and take the diference in the denominator which gives us (x - 3)³
2(x - 3)³ / (x - 3)³ = 2
4(x - 3)^6 / (x - 3)³ = 4(x - 3)³
so now we have:
2
-----
4(x - 3)³
we can simplify 2/4 and get 1/2 so now we have the following:
1
--------
2(x - 3)³
there is nothing else to simplify, so this is the final answer
2. to solve 8x/y² - 5x/y², we see they both have <em>like denominators</em>, this means that we can just combine the terms over one denominator and we get the following:
8x - 5x
----------
y²
we can subtract 5x from 8x because both have an x in them and are therefore able to be subtracted
8x - 5x = 3
so the final answer is 3x/y²
