Hi there! :)
Answer:
Choice D. (y - 4) = 3(x + 2)
Step-by-step explanation:
An equation in point-slope form is:
(y - y1) = m(x - x1)
Where:
y1 = y-coordinate of a point
m = slope
x1 = x-coordinate of a point
In this instance, the point given is (-2, 4) with a slope of 3. Therefore, the equation in point-slope form would be Choice D. (y - 4) = 3(x + 2)
A
Because of 3 adults bought 3 tickets, 9 x 3. 9(3)
4 students bought 4 tickets, 4 x 5, 4(3)
Every equilateral triangle is also anisosceles triangle, so any two sides that are equal have equal opposite angles. Therefore, since all three sides of an equilateral triangle are equal, all three angles are equal, too.
Let speed of bicycle be xmph
then speed of car will be x+33.6mph
total speed of both of them since they are moving towards each other= 2x+33.6
308miles/2x+33.6mph=5.5
2x+33.6=308/5.5=56
2x=56-33.6=22.4
x=11.2
bicycle ave rate is 11.2
car ave rate is 44.8
First get everything that has like terms on one side.
2b+3b=5.5+6.25
Then add things together to simplify.
5b=11.75
Finally, divide to find your answer.
b=11.75/5
b=2.35
