Answer:
<em>First option: </em> 
Step-by-step explanation:
Given the point-slope equation 
, you need to solve for 
, because you are looking for the equation of the line in slope-intercept form:
Being 
the slope of that line, and 
the intersection of the line with the y-axis.
Then:
Apply Distributive property:
Subtract 7 from both sides:
Rewrite the equation:
(The linear function of the First option)
Answer
91
Step-by-step explanation:
62+27+x=180
In the question, the angles proves that this triangle is an isoceles triangle.
So we can set the two sides equal:
Add
to both sides of the equation:
Divide both sides by 2:
We find that
. AC is also x, so, it is 6 too.
Answer:
a)
0.8 hours
b)
1.1 kilometers/min
Step-by-step explanation:
a)
D = distance between town A and town B = 45 kilometers
v = speed of the train traveling from town A to town B = 60 kilometers per hour
t = time taken for the train to travel from town A to town B
Time taken is given as
t = D/v
inserting the values
t = 45/60
t = 0.8 hours
b)
D = distance between town A and town B = 45 kilometers
v = speed of the train traveling from town A to town B = ?
t = time taken for the train to travel from town A to town B = 40 minutes
Speed of the train is given as
v = D/t
inserting the values
v = 45/40
v = 1.1 kilometers/min
Answer:
mass is less than the red
speed is equal
energy is less than
Step-by-step explanation:
Hope this helps!
