I'm assuming this is trig - is this all for one triangle and is it right?
If you would like to know what is the solution to the system of equations, you can calculate this using the following steps:<span>
2d + e = 8
d - e - 4 = 0 ... d = e + 4
___________________
</span>
<span>2d + e = 8
</span><span>2 * (e + 4) + e = 8
2e + 8 + e = 8
3e = 0
e = 0
d = e + 4 = 0 + 4 = 4
(d, e) = (4, 0)
The correct result would be: C. The solution is (4, 0).</span>
Answer:
n=6
m=4.5
I don't know about the angle though
Step-by-step explanation:
sf = 1.5
1.5x4=6
1.5x3= 4.5
Answer:
point slope form:
y - 3 = -4/3(x- (-1))
slope intercept form:
y = -4/3x + 13/3
Step-by-step explanation:
So if the points are (7, -4) and (-1,3) then we can use those points to figure out the slope.
y2-y1/x2-x1 is the forumla for the slope
3-7/ -1 - (-4) --> -4/-1+4 --> -4/3
point slope form:
y - y1 = m(x-x1) ~ you can choose either of the two points to use, you should get the same answer
y - 3 = -4/3(x- (-1))
y - 3 = -4/3x+4/3
add 3 to both sides
y = -4/3x + 13/3 ~ slope intercept form
