PLEASE HELP!!!

Trava [24]

1/3x - 2 = 1/4x + 11....it looks to me like one y was subbed in for another...

ur 2 equations are :
y = 1/3x - 2 and y = 1/4x + 11...but we need them in standard form...

y = 1/3x - 2
-1/3x + y = -2 ..multiply by 3
-x + 3y = -6.....or 3y - x = -6 <==

y = 1/4x + 11
-1/4x + y = 11 ...multiply by 4
-x + 4y = 44 or 4y - x = 44 <==

Leona [35]

The inequality is used to solve how many hours of television Julia can still watch this week is $x + 1.5 \leq 5$

The remaining hours of TV Julia can watch this week can be expressed is 3.5 hours

<h3><u>Solution:</u></h3>

Given that Julia is allowed to watch no more than 5 hours of television a week

So far this week, she has watched 1.5 hours

To find: number of hours Julia can still watch this week

<em>Let "x" be the number of hours Julia can still watch television this week</em>

"no more than 5" means less than or equal to 5 ( ≤ 5 )

Juila has already watched 1.5 hours. So we can add 1.5 hours and number of hours Julia can still watch television this week which is less than or equal to 5 hours

number of hours Julia can still watch television this week + already watched ≤ Total hours Juila can watch

$x + 1.5 \leq5$

Thus the above inequality is used to solve how many hours of television Julia can still watch this week.

Solving the inequality,

$x + 1.5 \leq5\\\\x \leq 5 - 1.5\\\\x \leq 3.5$

Thus Julia still can watch Television for 3.5 hours

2. A surveyor measures the distance across a river that flows straight north by the following method. Starting directly across f

IgorLugansk [536]

Answer:

The wide is 70.02 m.

Step-by-step explanation:

First you need to draw a triangle with only one 90 degrees angle.

The opposite side to the 90 degrees angle will be the hypotenuse.

We will call the remaining sides ''Baseline'' and ''River wide''.

The angle between hypotenuse and baseline is 35 degrees.

The triangle has one 90 degrees angle so we can apply the tangent equation

in the angles that are no 90 degrees.

Tangent (angle) = Opposite side/adjacent

Tan(35°)= River wide/100m

River wide = 100m.Tan(35°)

River wide = 70.02 m
