[multiply the first equation by -2]
[-2x - 10y = 4]
[add like terms between the equations]
[-5y = 10]
[y = -2]
[x = 8]
(8, -2)

You can use the subtraction method to eliminate the 5y. Then you would subtract x and 2x to get -x. Next, subtract the 6 from the -2 to get -8. Now we know that -x=-8 so then x=8. Finally substitute x for 8 and solve for y

Which expression is equivalent to (5^3)^-2?
s2008m [1.1K]

Answer:

The Last One

Step-by-step explanation:

1/5 x 5 x 5 x 5 x 5 x 5

Because:

5 x 5 = 25

25 x 5 = 125

125 x 5 = 625

625 x 5 = 3125

3125 x 5 = 15625

And (5^3)^-2 is equal to 1/15625

Hope This Helps! :)

Answer:

MN = 3

Step-by-step explanation:

The following are congruent to each other as each pair are tangents of a circle drawn from the same external point:

PQ = QJ = 1

JK = KL = 4 - 1 = 3

MN = ML

Thus, ML = KM - KL

ML = 6 - 3 = 3

Therefore, MN = ML = 3 (both are tangents drawn from the same external point, M.

100 POINTS<br> PLEASE EXPLAIN AND ADD STEPS. THANK YOU IN ADVANCE
e-lub [12.9K]

Given one to one f(6)=3, f'(6)=5, find tangent line to y=f⁻¹(x) at (3,6)

OK, we know

f⁻¹(3)=6

The inverse function is the reflection in y=x.  So slopes, i.e. the derivative will be the reciprocal.  We know the derivative of f at 6 is 5, so the derivative of f⁻¹  at y=6 is 1/5, which corresponds to x=3.

f⁻¹ ' (3) = 1/5

That slope through (3,6) is the tangent line we seek:

y - 6 = (1/5) (x-3)

That's the tangent line.

y = x/5 + 27/5
