How to solve the problem 3.2d-4d=2.3d+3
Liula [17]
3.2d - 4d = 2.3d + 3...simplify by combining like terms
-0.8d = 2.3d + 3....subtract 2.3d from both sides
-0.8d - 2.3d = 3 ...simplify again
-3.1d = 3...divide both sides by -3.1
d = 3/ -3.1
d = - 0.97

or
3.2d - 4d = 2.3d + 3....multiply the equation by 10, gets rid of the decimals
32d - 40d = 23d + 30....subtract 23d from both sides
32d - 40d - 23d = 30....simplify
-31d = 30...divide by -31
d = -30/31
d = - 0.97

If a line with a slope of -2 crosses the y-axis at (0, 3), what is the equation of the line?
Karo-lina-s [1.5K]

Answer: Option D

y +2x = 3

Step-by-step explanation:

The equation of a line in the form of "slope-interception" has the following form:

y = mx + b

Where m is the slope of the line and b is the interception of the line with the y axis.

In this case we know that the line has a slope of -2. Then m = -2.

We also know that the line intercepts the axis y at the point (0, 3) therefore we know that:

b = 3.

Finally the equation of the line will be:

y = -2x + 3

If we add 2x on both sides of the equation we get:

y +2x = 3

The answer is the option D
