Y=-3/2x+4

The slope is -3/2, since Kerry traveled three feet and only went down 2.

The y intercept is 4, since she started four feet above the origin

Which value of x makes the following equation true?

Goryan [66]

Answer:

Step-by-step explanation:

multiply through by 10

10{4.8(x-4)} = 10(-0.2x) + 10(15.8)

48(x-4) = -2x + 158

48x - 192 = -2x +158

48x + 2x = 158 + 192

50x = 350

divide through by 50

x=350/50

x=7

therefore, answer = C

find the ratio which are the points p(X,2) divides the line segment joining the point a(12,5) and b(4,-3) also find X plz give a

chubhunter [2.5K]

Answer: ratio a:b = 3:5 p(X, 2) = p(9, 2)

Step-by-step explanation:

Plot points a = (12, 5) and b = (4, -3) and draw a line segment from a to b.

Notice that when y = 2, X = 9 so point p = (9, 2) see graph

The distance from a to p = 3√2

The distance from b to p = 5√2

So the ratio of a:b = 3√2:5√2 = 3:5 when simplified

To find the distance, use the distance formula OR pythagorean theorem.
