Answer:
(6, 3 )
Step-by-step explanation:
Given the 2 equations
5x - y = 27 → (1)
5x + 4y = 42 → (2)
Multiplying (1) by - 1 and adding to (2) will eliminate the x- term, that is
- 5x + y = - 27 → (3)
Add (2) and (3) term by term to eliminate the x- term
5y = 15 ( divide both sides by 5 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (2)
5x + 4(3) = 42
5x + 12 = 42 ( subtract 12 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Solution is (6, 3 )
Answer:
m=2
Step-by-step explanation:
(x1,y1)=(−7,−6)
(x2,y2)=(−3,2)
m=
y2−y1 / x2−x1
= 2−−6 / −3−−7
= 8/4
m=2
Can you give me Brianliest please
Negative x Negative = Positive.
-0.25 x -1 = 0.25
On the first one you do 2x 2x2 • 2x2x2x2x2 = 60
