Edna has a segment with endpoints f(4, 9) and g(7, 2) that is divided by a point h such that fh and gh form a 1: 3 ratio. she knows that the distance between the x-coordinates is 3 units. which of the following fractions will let her find the x-coordinate for point h?

1 over 4
1 over 3
3 over 4
3 over 1

answer:

a. 1/4

step-by-step explanation:

because the ratio is 1: 3 you need to divide the graph into 4 equal parts (1+3=4) or 1/4.

answer: i realy don't get it that much can you me figer it out pleas you

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
