Hey there!

To make a line perpendicular to another line, you have to find the reciprocal. The reciprocal of 3/4x is -4/3x. Any y-intercept would work. So let’s just say 1. The answer would be y=-4/3x+1.

I hope this helps!

It will be
.. y = -4/3x +c . . . . . for some value of c

_____
The slope of the perpendicular line will be the negative reciprocal of the slope of the given line, which is 3/4.

You and your friend collect each rocks and fossils. your friend collects three times as many rocks and half as many fossils as y

Murljashka [212]

Answer:

you - 4 rocks and 16 fossils
friend - 12 rocks and 8 fossils

Step-by-step explanation:

Let the rock be r and the fossil be f

Equations

You: r + f = 20
Friend: 3r + 1/2f = 20

Double the second equation and subtract the first one:

2(3r + 1/2f) - (r - f) = 2*20 - 20
6r - r = 20
5r = 20
r = 4

Then find f:

f = 20 - 4 = 16

So you collect 4 rocks and 16 fossils

Friend collects:

4*3 = 12 rocks and
1/2*16 = 8 fossils

Simplify. 1/3(1−1/4)^2 Enter your answer, as a simplified fraction, in the box.

Slav-nsk [51]

Remember that $(\frac{a}{b})^c=\frac{a^c}{b^c}$

simplify inside parentahsees first

1-1/4=3/4

1/3(3/4)^2=
$(\frac{1}{3})(\frac{3}{4})^2=$
$(\frac{1}{3})(\frac{3^2}{4^2})=$
$(\frac{1}{3})(\frac{9}{16})=$
$\frac{9}{48}=$
$\frac{3}{16}=$
