Answer:

a) P = 6x + 13//

b) i) x = 5//

ii) 9//

Step-by-step explanation:

a) P = 2(x+2) + 2(2x-1) + 3 + 8 m

= 2x+4 + 4x-2 + 3 + 8

= 6x + 13//

b) i) P = 43 m

43 = 6x + 13

43-13 = 6x

<u>3</u><u>0</u> = <u>6</u><u>x</u><u> </u>

6 6

x = 5//

ii) longest side = (2x-1) m

2 × 5 - 1

10-1 = 9//

Which statement is true about the graphs of the two lines y= -4/5x + 2 and y = - 5/4x - 1/2?
vagabundo [1.1K]

They have no relation, except for the fact that they intersect.

We have given that,

The graphs of the two lines y= -4/5x + 2 and y = - 5/4x - 1/2

If the equations were instead y = +5/4x - 1/2 and

<h3>What is the slope of the perpendicular line?</h3>

Vertical lines and horizontal lines are perpendicular to each other. The slope of the perpendicular line in this case would be the slope of a horizontal line which would be 0. The slope of the parallel line is undefined and the slope of the perpendicular line is 0.

y = -4/5x + 2, or

y = +4/5 + 2 and

y = -5/4x -1/2,

Then they would be perpendicular.

Point S lies between points R and T on .
Marat540 [252]

Answer:

the value of  line ST is 6 centimeters long

Step-by-step explanation:

The attached image in conjunction with the question is shown in the file below.

We can see from the RT segment that the equation given can be expressed as:

\mathbf{2x+3x = 10}

so; if we solve for x ; we have ;

\mathbf{5x= 10}

divide both sides by 5 ; we have:

\mathbf{\dfrac{5x}{5}= \dfrac{10}{5}}

\mathbf{x=2}

However ; the value of ST is represent by the information:

\mathbf{ ST = 3x}

replcaing the value for x; we have :

\mathbf{ ST = 3*2}

\mathbf{ ST = 6}

Thus, the value of  line ST is 6 centimeters long

Help !!!!! Also show me how to do it if you can guys
natali 33 [55]

Answer:

D.

Step-by-step explanation:

A is linear, you can figure out that y=x+5

B is linear, y=22(x+1)

C is linear, y=8x+5

D is exponential, y=3ˣ⁺¹

Deriving these formulas is a matter of trial and error if you know you can choose between linear and exponential.
