Answer:
The distance of the point P(-6, 8) from the origin is
OP2=(-6)2+82=36+64=100⇒OP=√100=10 units
Answer:
$14.88
Step-by-step explanation:
Ria earns 1.2 times more than Peter does
Peter earns $12.40
To solve, you have to multiply the amount peter has by 1.2
12.40(1.2) = 14.88
Therefore, Ria earns $14.88
Answer:
=−14x+18
Step-by-step explanation:
happy to help ya :)
I think the answer would be A
Please use " ^ " to indicate exponentiation: x^2 + 3x - 4 = 0
Here, a = 1, b = 3 and c = -4.
The formula for the discriminant is b^2 - 4(a)(c).
Substituting the given values of a, b and c, we get:
(3)^2 - 4(1)(-4)
Evaluating this, we get 9 + 16 = 25.
The discriminant is 25.
-3 plus or minus √25
Taking this further, x = ------------------------------------
2
-3 plus or minus 5
or: x = -------------------------------- => {-4, 1} (solutions)
