What are the coordinates of the point on the directed line segment from (1,-5) to
Black_prince [1.1K]

Answer:

Q (2.5, -4)

Step-by-step explanation:

Let A (1, -5), C = (10, 1), find Q (x, y), so that AQ:QC = 1:5

AQ = (x - 1, y + 5)

QC = (10 - x, 1 - y)

AQ:QC = 1:5

so 5*AQ = QC

5(x - 1) = (10 - x)

5(y + 5) = 1 - y

Solve them:

5x - 5 = 10 - x

6x = 15

x = 15/6 = 2.5

5y + 25 = 1 - y

6y = -24

y = -24/6 = -4

Then answer is Q (2.5, -4)

Can someone help me understand this!!!
otez555 [7]

Answer:

7b, 8a

Step-by-step explanation:

using the equation y=m(x)+b, m(x) is the slope, and b is the y intercept. Oky so for 7, its a slope of negative 2, and it has a y-intercept of 5, and if you look at graph b a  slope of -2 and would be a y-intercept of 5.

looking at equation a, its a Quadric function, f(x)=x^2, but it doesn't match the graph... strange because the graph for that equation would look like the image included. Hopefully this helps!
