<span>Standard form means that you write the terms by descending degree.
</span>
<span>
The degree of the first term </span>
is
.
The degree of the second term
is
.
The degree of the third term
is
.
The terms are written by descending degree. Therefore, polynomial
is written in standard form.
3x-6y=12
y=mx+b
-6y=-3x+12 <- divide by -6 to make y by itself
y=1/2x-2
The y-intercept is (0,-2)
x-intercept: put 0 in for y
0=1/2x-2
2=1/2x
x=4
(4,0)
Y intercept: (0,-2)
X-intercept (4,0)
Answer:
21/7
Step-by-step explanation:
One way of doing it is by using the properties of summing things, like factoring out the minus sign:
<span><span>∑<span>n=2</span>8</span><span>−(n−5)</span>=−<span>∑<span>n=2</span>8</span><span>(n−5)
</span></span>
and splitting it up into two parts and again factor
<span>=−<span>(<span><span>∑<span>n=2</span>8</span><span>n−5<span>∑<span>n=2</span>8</span>1</span></span>)
</span></span>
The last sum is just counting how many numbers there are from 2 to 8, which is 7 (you can do it on your fingers). The first one can be calculated fast if we are clever and use this identity:
<span><span>∑<span>n=1</span>m</span>n=<span><span>m(m+1)</span>2
</span></span>
So what we get is
<span><span>=−<span>(<span>−1+<span><span>8(8+1)</span>2</span>−7</span>)</span>=8−72/2=8−36=−28.</span></span>
Answer:
A triangle has angle measures of 45, 110, and 25 degrees would has an orthocenter outside the triangle.
Hope this helps!
