Well, in order to answer this problem we need to use the <span>the Pythagorean Theorem and the it will be like this:
cos = x / hypotenuse
cos= 12/13
I think with this you can figure the rest out. Hope this helps</span>
Answer:
Option A
Step-by-step explanation:
Thisbis because when two of them are hanged on the same side it means that it's addition. (Addition of weight)
Answer:
The slope is -
and the y intercept is 2.
Step-by-step explanation:
So, we can see that the line moves down one unit every time it progresses to the right three times. Slope is defined by change in y/change in x. For this problem, the change in y is -1 and the change in x is +3, so the slope is 
.
Now for the y intercept. The y intercept is the point where the line first passes through the y axis. In this case, it passes through 2. Your y intercept can be written in two ways; as a number (2) or as an ordered pair 
, although people usually write the number.
I hope this was helpful. Good luck!
There are several ways in solving quick the 20% of any bill. One of those ways is by getting first the 10% of the amount then will later on be multiplied by two. Another one is by simply dividing the total bill amount by 5, which also 20% of the total bill amount. Hope this helps.
Answer:
y = 3/2
, x = 3/2
Step-by-step explanation:
Solve the following system:
{x + y = 3 | (equation 1)
10 x = 15 | (equation 2)
Divide equation 2 by 5:
{y + x = 3 | (equation 1)
0 y+2 x = 3 | (equation 2)
Divide equation 2 by 2:
{y + x = 3 | (equation 1)
0 y+x = 3/2 | (equation 2)
Subtract equation 2 from equation 1:
{y+0 x = 3/2 | (equation 1)
0 y+x = 3/2 | (equation 2)
Collect results:
Answer: {y = 3/2
, x = 3/2
