Arrange the equations in increasing order of the value of their solutions.

Ulleksa [173]

See the explanation

<h2>Explanation:</h2>

The complete question is attached below. In order to solve this problem, we'll use a graphing tool. First of all, we'll say that the LHS is a linear function and the RHS is another linear function, so for each case, we'll have:

$f(x)=g(x)$

For each graph, $f(x)$ will be drawn in red while $g(x)$ will be drawn in blue.

Case 1:

$f(x)=\frac{1}{4}x+\frac{5}{2}x-2 \\ \\ g(x)=4-\frac{1}{4}x$

So by equating both equations:

$\frac{1}{4}x+\frac{5}{2}x-2=4-\frac{1}{4}x$

By using graphing tool we get a point of intersection at which the x-value is the solution to our equation. So:

<u>Solution:</u>

$\boxed{x=2}$

See First Figure below.

Case 2:

$f(x)=7.9x+x+4 \\ \\ g(x)=-1.1x-16$

Applying a similar method as in case 1.

<u>Solution:</u>

$\boxed{x=-5.8}$

See Second Figure below.

Case 3:

$f(x)=3.2x+5.7 \\ \\ g(x)=-2.5x$

Applying a similar method as in case 1.

<u>Solution:</u>

$\boxed{x=-1}$

See Third Figure below.

Case 4:

$f(x)=10.1x-1.6x+44 \\ \\ g(x)=-7$

Applying a similar method as in case 1.

<u>Solution:</u>

$\boxed{x=-6}$

See Fourth Figure below.

Slove this question c^2-81=0

Firdavs [7]

To solve a square root, get the ^2 on one side and the 81 on the other side.
add 81 to both sides.

c^2 = 81
to clear the power of 2, take the square root of both sides.
c = + - sqrt81
c = + - 9
c = 9 and c = -9

harrison bought a 10 foot ramp to load his dirt bike into the back of his truck. the ramp hooks to the 3 foot high tailgate. how

dangina [55]

Answer:

9.54 feet

Step-by-step explanation:

Using Pythagoras rule :

Length of ramp = 10 feets = hypotenus

Hypotenus² = opposite² - adjacent²

d² = 10² - 3²

d² = 100 - 9

d² = 91

d = √91

d = 9.5393920

d = 9.54 feets

Pelase help me thank you

Morgarella [4.7K]

Step-by-step explanation:

it has been awhile since ive done this.

so a line =180

so to find the other angle you simply subtract 120 from 180.
