Answer:
x = 4.5
Step-by-step explanation:
a^2 + b^2= = c^2
4^2 + 2^ = c^2
16 + 4 = c^2
20 = c^2 --> find square root of 20 and round to nearest tenth*
4.47 = c
round up to 4.5
Answer:
-10
Step-by-step explanation:
x+75=180-(x+125)
2x=-20
x=-10
Answer:
510
Step-by-step explanation:
Group and factor out the greatest common factor (GCF), then combine.
Answer:
Option 2, (y = 4/6x - 4)
Step-by-step explanation:
Knowing that m acts as the slope in general, we can conclude that part of the equation is as such:
y = 4/6x
Now we are given coordinate (0, - 4) so that here x = 0 and y = - 4. Let's substitute these values into the prior equation:
y = 4/6x
-4 = 4/6(0)
-4 = 0
Now in order for y (-4) to be equal to the opposite side of the equation you would have to add -4:
-4 = 0 - 4
-4 = -4
That would mean the equation represents:
y = 4/6x - 4
