Please help me ill put the question up for a lot of point, and i will mark as brainliest!!!
sattari [20]

Step-by-step explanation:

(2x³y^-4)^-2 = 1/(4x⁶y^‐8) = y⁸/(4x⁶)

1/(8x⁵y^-7) = y⁷/(8x⁵)

4x^-9y⁴ = 4y⁴/x⁹

so, the whole expression is then

y⁸/(4x⁶) × y⁷/(8x⁵) × 4y⁴/x⁹

4y¹⁹/(32x²⁰) = y¹⁹/(8x²⁰)

so, D is the correct answer.

Which is the equation of a line that has a slope of 1/2 and passes through point (2, -3)?
Varvara68 [4.7K]

Start with the point-slope formula: y-k = m(x-h), where (h,k) is the given point and m is the given slope:


y+3 = (1/2)(x-2)

This equation can be rewritten in other forms if desired.
