Pls help with this plsssssss

Answer:

x = 13

Step-by-step explanation:

We know that the angle across from 85° is 85° because of vertical angles. We also know that the 98° also has the same interior angle on the other parallel line because both lines are parallel. We subtract 96 from 180 to find the vertical angle for the right side of the triangle, which comes out to be 82°. Lastly, we solve x + 82 + 85 = 180 and we should get 13 as our answer.

y varies inversely with x. If y = 4 when x= -6, find the constant of variation and find the value of y when x= -2

Setler [38]

Answer:

constant of variation: k = -24

y = 12 when x = -2

Step-by-step explanation:

y varies inversely with x equation is: y = k/x

where 'k' if the constant of variation

plug in:

4 = k/-6

cross-multiply to get value of 'k' which is -24

plug in:

y = -24/-2

y = 12

My teacher wanted us to try this out, but I don't understand it as much.

statuscvo [17]

solve for the indicated variable means isolate that variable.

Ans(7)

P=IRT (T)

that means solve for T or make T alone on one side of equal.

To do that we just need to move IR on the left side

So we get:

$\frac{P}{IR}=T$

Hence final answer will be $T=\frac{P}{IR}$

2x-3y=8 (y)

-3y=8-2x

$y=\frac{8-2x}{-3}$

V=LWH (L)

$L=\frac{V}{WH}$

------------

Ans(10)

A=2(L+W) (w)

A=2L+2W

A-2L=2W

$\frac{A-2L}{2}=W$

$W=\frac{A-2L}{2}$

Ans(11)

ax+by=c (y)

by=c-ax

$y=\frac{c-ax}{b}$

Ans(12)

$P=\frac{R-C}{N}$ (R)

PN=R-C

PN+C=R

R=PN+C
