Answer:
C) 4/15
Step-by-step explanation:
The two equations ...
- 2x + 1/2y = 2
- 1/2x + 2y = 6
can be solved for x using Cramer's rule:
x = (2·2 -1/2·6)/(2·2 -1/2·1/2) = (4-3)/(4-1/4) = 1/(15/4)
x = 4/15
_____
Cramer's rule for the solution to ...
is ...
- ∆ = ae-db
- x = (ce -fb)/∆
- y = (fa-dc)/∆
Answer:
Step-by-step explanation:
The endpoint of the graph is the midpoint between 2 and 4, so it is 3.
This point is included since indicated as full circle.
<u>The graph includes the line to the left of 3:</u>
Use the 2 points and use the formula

to get slope

and you get a slope of -2
for the second question its non of the above? i think the x intercept is 0.6666. if you're talking about y intercept then its -5
False, because a^2+b^2=c^2 and no matter what numbers substitute for which ever variable the answer isn’t going to be true
A) -18
b) -18
c)24
d) 0
e) -4
f) 4
