Answer:
y+4 = 9/4(x-3)
Step-by-step explanation:
m=slope and b=y-intercept (probably useful for later on in the school years)
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
Substituting in what we know
y--4 = 9/4(x-3)
y+4 = 9/4(x-3)
Speed
Riding speed = 9 mph
Driving speed = 27 mph
Time
If x hours is the time taken when riding, (x - 1/3) hours is the time taken when driving.
Distance in both instances is the same, D= Speed * time
Therefore,
9*x = 27(x-1/3)
9x = 27x - 27/2
9x = 27x - 9
(9-27)x = -9
-18x = -9
x = 9/18 = 1/2 hours
Distance, D = 1/2 *9 = 4.5 miles
Answer is 10 cups divided by 3 cups = 1 pitcher smoothie,
10/3 or 3-1/3 pitchers of smoothies
I don’t see your choices so my answers might not be what you have to chose from
A sample graph is attached.
Answer:
x ≈ 41.6°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan x =
=
=
=
, then
x =
