Step-by-step explanation:
use law of cosine. you can search on wikipedia.
find u. then use law of cosine again to find angle T. but i think you need use calculator
This is asking for slope intercept form. See attached
[Slope]
The slope is -.
-> Start at (0, 0)
-> Count four units down and three units right to the next point
-> Since this line is going from top left to bottom right, the slope is negative
[Y-intercept]
Since this line goes through the orgin, (0, 0), there is no y-intercept. Hence why this value is nonexistent in the equation they give to fill out.
Answer:
To fill it in for your assignment, see attached or read below;
The slope itself should be negative, so enter a "-" (or however you do it)
The question mark, outlined in green, should be 1
The top of the fraction, the numerator, should be 1
The bottom of the fraction, the denominator, should be 3
The equation of the line that passes through (4,-1) and (-2,3) is y=-2/3x+5/3. You have to use two points to find the equation. Use the formula y=mx+b to solve.
For copy of AB, (call it A'B').
Draw a line approximately horizontal in the space provided.
Use a pencil to mark the left end and call it A'.
Put the compass (a math tool, not the one that shows north in the woods) point at A, and stretch the pencil end to match B.
Now move the compass point to A' and use the pencil to mark on the line you drew the point B'.
That's it. A'B' is a copy of AB.
Do the same for CD and EF.
Answer:
(7,0)
Step-by-step explanation:
By Multiplying 4 and 7 (aka x), it will equal 28.
Multiplying 9 and y, (aka 0) , it will equal to 0
4(7)+9(0)=28
multiplying -4 by 7 will equal to -28 ,minus y which is 0, total will be -28
