Answer:

\bigtriangleup=2.4\ cm

Step-by-step explanation:

-The difference in length is calculated by subtracting as:

\bigtriangleup=6.82-4.392\\\\=2.428\ cm

-To estimate the length difference, we use the given lengths rounded off to the nearest tenth of a centimeter:

\bigtriangleup=6.8-4.4\\\\=2.4\ cm

-The two differences are reasonably close to each other and an exact match when rounded off to the nearest tenth:

2.428\approx2.4\ cm =2.4\ cm

Which of the coordinates listed below could represent a point found on the line 3x?
Kamila [148]
Well.. You seem to have forgotten to add the coordinates...

Anyway, the line is represented by the function f(x) = 3x .

Any point which follows the form (x,3x) will be on the line

for example (-3,-9) ; (-2,-6) ; (-1,-3) ; (0,0) ; (0.333333,1) ; (1, 3) ; (2,6) ; (3,9) ; and so on....

Use substitution to solve the system of equations<br> Y+x=3<br> Y=1.5x+1
Serjik [45]

The solution to given system of equation is (x, y) = (0.8, 2.2)

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

y + x = 3 --------- eqn 1

y = 1.5x + 1 ---------- eqn 2

We have to solve the above system of equations by substitution method

<em><u>Substitute eqn 2 in eqn 1</u></em>

1.5x + 1 + x = 3

Combine the like terms

2.5x + 1 = 3

Move the constants to Right hand side of equation

2.5x = 3 - 1

2.5x = 2

x = 0.8

<em><u>Substitute x = 0.8 in eqn 2</u></em>

y = 1.5(0.8) + 1

y = 1.2 + 1

y = 2.2

Thus the solution to given system of equation is (x, y) = (0.8, 2.2)
