Answer:
4/6
Step-by-step explanation:
5 2/6 - 4 4/6 = 4/6
Answer:
(3,7), (3,8), (3,9), (3,10) is not a function.
Step-by-step explanation:
A function is defined as a relation in which each input value has only a single output value.
This means that for each 
value there should be only one 
value. If this criteria is not fulfilled then the relation cannot be called a function.
For the given set of points, we notice that for 
, 
which shows there are many y-values o for a single x-value. This means there are many outputs for a single input. This disqualifies it to be a function.
Thus, (3,7), (3,8), (3,9), (3,10) is not a function.
Answer:
3x - y = -7
Step-by-step explanation:
put into slope-intercept form the equation becomes <em>y = 3x + 7</em>
parallel lines have the same slope, in this case the slope is 3
Answer:
81000000
Step-by-step explanation:3x3=9x9=81
10x10x10=1000x1000=1000000
1000000x81=81000000
One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)
With all this information, you should have the equation:
n + 8n = 90
To solve, combine like terms to get:
9n = 90
Divide by 9 on both sides to isolate the variable n.
n = 10
Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.
