The answer to your question is a) y = 1.5x - 6

b) y = -4x + 6.1

c) Point (2.2, -2.7)

Step-by-step explanation:

First line Second line

P (0, -6) Q (1, -4.5) R (0, 6.1) S (1, 2.1)

m = (-4.5 + 6) / (1 - 0) m = (2.1 - 6.1) / (1 - 0)

m = 1.5 / 1 m = -4/1

m = 1.5 m = -4

Line Line

y - y1 = m(x - x1) y - 6.1 = -4(x - 0)

y + 6 = 1.5(x) y - 6.1 = -4x

y = 1.5x - 6 y = -4x + 6.1

Solve the system by equality

1.5x - 6 = -4x + 6.1

1.5x + 4x = 6.1 + 6

5.5x = 12.1

x = 12.1 / 5.5

x = 2.2

Find y

y = 1.5(2.2) - 6

y = 3.3 - 6

y = -2.7

Point (2.2, -2.7)

Answer from: Quest

$4\left(625^4\right)\left(y^6\right)$

step-by-step explanation:

given expression is $4\sqrt{625^8y^{12}}$ .

now we need to simplify the given expression $\sqrt{20y^8}$ .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

$4\sqrt{625^8y^{12}}$

$=4\left(625^8y^{12}\right)^{\frac{1}{2}}$

$=4\left(625^8\right)^{\frac{1}{2}}\left(y^{12}\right)^{\frac{1}{2}}$

$=4\left(625^4\right)\left(y^6\right)$

expanding that will give a very very large number so let's keep answer in exponent form.
