Ayoung equestrian loved to ride her horse all day long, dreaming of the day
she would ride in the kentucky derby. one day in early april, she left home at
10: 00 am and rode her stallion at a nice, steady 10 miles per hour away from
her house. at noon a call came in from the derby saying she was in! her
father immediately jumped on his scooter and rides at a breezy 15 miles per
hour to try and track her down and tell her the good news.
on what scale would you measure the number of minutes the father must
ride his scooter before catching up to his daughter?
o
a. ten thousands
o
b. thousands
o
c. tens
o
d. hundreds

Ten thousands

Step-by-step explanation:

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
