Answer:
y + 20 = 1(x + 10)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 10, - 20) and (x₂, y₂ ) = (1, - 9)
m = =
= 1
Using (a, b) = (- 10, - 20), then
y - (- 20) = 1 (x - (- 10)), that is
y + 20 = x + 10

Answer:
h ≈ 9.9 cm
Step-by-step explanation:
By applying tangent rule for the given angle in the given right triangle,
tan(51°) =
tan(51°) =
h = 8 × tan(51°)
h = 9.879
h ≈ 9.9 cm
Therefore, measure of side 'h' is 9.9 cm.
Solution:
The gas can is filled at the rate of 320 cubic inches per minute.
The can is 10 inches long, 8 inches wide, and 12 inches high.
So volume of the can=10 in*8 in *12 in
Time required to fill the can
Hence Time required to fill the can =3 minutes.
