Answer:
a = 3
Step-by-step explanation:
Calculate the distance d using the distance formula and equate to 4
d =
with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (2, a)
d = =
=
= a + 1 then
a + 1 = 4 ( subtract 1 from both sides )
a = 3

Answer:
Jacob ran 40 yards more than Ali.
Step-by-step explanation:
Football field is in the shape of a rectangle having dimensions 120 yards × 50 yards
Since Jacob runs around the perimeter of the field from one corner to other corner, therefore, distance run by Jacob =
Distance run by Jacob = 50 + 120 = 170 yards
Ali runs through the middle of the field diagonally on a straight line.
Therefore, distance covered by Ali =
=
=
=
= 130 yards
Now difference between the distance covered by Jacob and Ali
= 170 - 130
= 40 yards
Therefore, Jacob ran 40 yards more than Ali.
Answer:
Slope(m) = 16
Y intercept (c) = 23
Step-by-step explanation:
Given:
Points : (x1, y1) = (2, 55)
(x2, y2) = (4, 87)
Using two point form to calculate slope:
m = 16
To find y intercept:
Take any one point ans slope :
Using slope point formula:
y = mx + c
87 = 16(4) + c
Solving for c:
c = 23
