Answer:
<h2> I am not so good at drawing .</h2><h3>BE = 3.6</h3>
Answer:
B
Step-by-step explanation:
y= -x+18 and y= 3/4x+4
use slope intercept form: y=mx+b
m = slope
b = y-intercept
The sin <ABC means that AC/AB. So we know AB=34. AC/AB=8/17. So the length of AC is 16. cos<ABC means BC/AB. tan<ABC means AC/BC.
Answer:
x = -1, y = -2.
Step-by-step explanation:
Using the elimination method,
multiply the first eqn by 2 and the 2nd eqn by 5.
6x - 10y = 14
25x - 10y = -5
Subtract one of the new equations from the other
-19x = 19
x = -1
Sub x=-1 into the 2nd eqn
-5 - 2y = -1
y = -2
Hence x = -1, y = -2.
