Answer:
(2, -8)
Step-by-step explanation:
y=6x-20
y=-4x
since the bottom equation shows us that y=-4x, we can substitute 4x in place of y in the first equation and solve:
-4x=6x-20
-10x=-20
x=2
since the bottom equation shows y=-4x, and we already know that x=2:
y=-4(2)
y=-8
(2, -8)
Answer:
52a² - 39a
Step-by-step explanation:
Step 1: Write out expression
3a(4a - 5) - 4a(6 - 10a)
Step 2: Distribute
12a² - 15a - 24a + 40a²
Step 3: Combine like terms (a²)
52a² - 15a - 24a
Step 4: Combine like terms (a)
52a² - 39a
Answer:
0.2 repeating
Step-by-step explanation:
If two triangles are similar, then there is a constant ratio between their corresponding sides. With the side lengths provided we find that:
24/16 = 19.5/13 = 6/4
Then, the diagram is:
Line C is a transversal line :D
