X + y = 6
x - 6y = -9
Subtract the equations, you get:
y - (-6y) = 6 - (-9)
7y = 15
y = 15/7
x + 15/7 = 6
x + 15/7 = 42/7
x = (42-15)/7
x = 27/15
None of your answer choices are correct, since the solution to the systems of equation is (27/15, 15/7)
<span>y=1/3 x - 2
3y = x - 6
x - 3y = 6 ...this is standard form</span>
<span>The radius of a sphere join refers to the (D) the center and a point on the sphere. A radius is the distance of the center point to any sides of the circle or sphere. The point on the sphere can be anywhere. The center and a point on the sphere forms a sphere join.</span>
Hi,
So we have g(x) = 4√(x). We're looking for g(45). Think of it like this: whatever number is in the place of x in g(x), just place that number AS x.
Therefore, we have :
g(45) = 4√(45) ⇒ (4) × (√(45)) ⇒ (4)(3√(5)) = 12√(5).
-Hope this helps!
substitute 4 as x in both sides of the equation
basically multiply -3/2 by 4
