What is the valuable of x in the equation 1.8-3.7x=-4.2x+0.3
Mumz [18]

Answer:

x = 3

Step-by-step explanation:

1.8 - 3.7x = -4.2x + 0.3

add -4.2x to both sides

1.8 - 0.5x = 0.3

subtract 1.8 from both sides

-0.5x = 0.3 - 1.8

-0.5x = -1.5

divide by -0.5 on both sides

x = 3

GREAT JOB!!!! YOU GOT IT!!! =)

Alina [70]

Answer:

A = 5.5t + 9

Step-by-step explanation:

We assume that the relationship between t and A is linear.

We have two points on a line: (2, 20) and (4, 31).

We now find the equation of the line.

A = mt + b

m = (31 - 20)/(4 - 2) = 11/2 = 5.5

20 = 5.5(2) + b

20 = 11 + b

b = 9

A = 5.5t + 9

The graph below shows a line segment MN: graph of line MN going through ordered pairs negative 2, 3 and 1, negative 3 Which of t
Katyanochek1 [597]
The line segment goes through (-2,3) and (1,-3).

The slope of the line is
\frac{-3-3}{1-(-2)} = \frac{-6}{3} =-2

Therefore the equation of the line segment is of the form
y = -2x + b

Because the line segments goes through (-2,3), therefore
-2(-2) + b = 3
4 + b = 3
b = -1

Answer: The equation is y = -2x - 1
