Answer:
D. x-6
Step-by-step explanation:
4x^2 - 4x - 120
4(x-6)(x+5) are the factors.
Height, h of the cone is 3V/πr²
Step-by-step explanation:
- Step 1: Find formula for height.
Volume, V = 1/3 πr²h, where r is the radius and h is the height of the cone.
Cross-multiply to find formula for height.
∴ Height, h = 3V/πr²
From googling linear pair you we now that both angles add to 180.
2x + (2y - 10) = 180
You are missing out information since there are two unknowns, x and y. To solve two unknowns we need to equations. If you would like to comment what the other equation could be i.e. there could be another 'linear pair' rule that I don't know about - which is likely - I'd reply and solve it better for you.
Answer:
x=1/3 or 0.3
Step-by-step explanation:
Multiply to remove the fraction, then set equal to 0 and solve.
Answer:
(-1, -2)
Step-by-step explanation:
Plug (x-1) for y in the first equation:
-4x + 3(x-1) = -2
Simplify:
-4x + 3x - 3 = -2
-x = 1
x = -1
Plug in x=-1 into the second equation:
y = (-1) - 1
y = -2
