Answer:

x ≥ -3

Step-by-step explanation:

5(9-x)≤4(x+18)

45-5x≤4x+72

subtract 4 from both sides

45-9x≤72

subtract 45 from both sides

-9x≤27

divide by -9, but when you divide by a negative in an inequality you have to flip the sign

x≥-3

Answer:

-3 ≤ x

Step-by-step explanation:

5(9-X)≤ 4(X+18)

Distribute on both sides

45 -5x ≤ 4x + 72

Add 5x to each side

45 -5x+5x ≤ 4x+5x + 72

45  ≤ 9x + 72

Subtract 72 from each side

45-72 ≤ 9x + 72  -72

-27 ≤ 9x

Divide by 9

-27/9 ≤ 9x/9

-3 ≤ x

(-3, 6) & m = -¹/2 what’s this equation in point slope form
Gre4nikov [31]

The equation of the line in point-slope form is <u>y - 6 = (-1/2)(x - (-3))</u> which can be simplified as <u>x + 2y = 9</u>.

The equation of a line that has a slope m, and passes through the point (x₁, y₁) is given by the point-slope form of a line, which can be shown as:

(y - y₁) = m(x - x₁).

In the question, we are asked to find the equation of the line in point-slope form, that passes through the point (-3, 6) and has a slope m = -1/2.

We know that the equation of a line that has a slope m, and passes through the point (x₁, y₁) is given by the point-slope form of a line, which can be shown as:

(y - y₁) = m(x - x₁).

Taking (x₁, y₁) as (-3, 6) and m = -1/2, in the point-slope form, we get the equation of the line as;

y - 6 = (-1/2)(x - (-3)).

This can be simplified as:

2y - 12 = - x - 3,

or, x + 2y = 9.

Thus, the equation of the line in point-slope form is <u>y - 6 = (-1/2)(x - (-3))</u> which can be simplified as <u>x + 2y = 9</u>.

Mark and Sofia walk together down a long, straight road. They walk without stopping for 4 miles. At this point Sofia says their
victus00 [196]

Answer:

b

Step-by-step explanation:

Displacement and distance have different meanings. Displacement is a vector quantity and is the objects overall change in position. Distance is scalar quantity which describes how much ground an object covers during motion.

If they have covered 4 miles from a origin and we don't know the origin but we know that they start there and continue for 4 miles. It will be displacement if they started at a distance and walked a certain distance and the difference from start to finish is 4 miles. Therefore, it must be distance because we don't know the initial position and only that they walked 4 miles.

Mark is right if their starting point is a origin of a coordinate system
