Answer:

r = -1

Step-by-step explanation:

(y2-y1)/(x2-x1)=m

(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5

so plug in...

(4-7)/(4-r)=-3/5

then solve for r which will get that r = -1

numerator: 4-7=-3

denominator: 4-r=5 -> 4-5=0+r -> -1=r

If Log x (1 / 8) = - 3 / 2, then x is equal to. A. - 4 B. 4 C. 1 / 4 D: 0

Softa [21]

$log_{x}(1/8)=-3/2$

This is equal to...

$x^{-3/2}=1/8$

We want "x" so we need to isolate it using laws of exponents...

$x^{(-1)(3/2)}=1/8$

$x^{3/2}=8$ because $x^{-a}=1/x^{a}$

$x=\sqrt[3]{8^{2}}$ because $x^{a/b}=\sqrt[b]{x^{a}}$

x = 4

answer: B

Sati [7]

If it goes from a higher number to a lower number it is a decrease.

(15,295 - 9182) / 15295....x 100
6113 / 15295 = 0.399....x 100 = 39.9% decrease
