yes and.... please explain more.... I will make sure I edit my answer
Answer:
y= 6/5x -8
Step-by-step explanation:
The slope-intercept form (basically the form for the equation of a line)
y=mx+b
m is the slope
x is the value you want to plug in, or the x term in a point (x, y)
we know so far,
y=6/5x + b
so to find the missing value let's plug in the x & y value from (5, -2) and use the given slope
-2 = 6/5(5) + b
6 / 5 x 5/1 or 6/5 times 5 is 30/5 or 6
so
-2 = 6 + b
subtract 6 from each side to isolate the b value or y-intercept ( the point on the graph that is on the y-axis)
-8 = b
Answer:
y=3x-10
Step-by-step explanation:
gradient to the line y=3x+2 is same as that of the line passing through the point (2,-4)
gradient=3
( {y-(-4)}/{x-2} )=3
apply cross multiplication and the equation will be:y=3x-10
Answer:
1) A
2) B
Step-by-step explanation:
For this problem we use exponential growth formulas
if the population increases when t increases
If the population decreases when t increases
Where and is the population as a function of time, 
is the initial population, r is the growth rate, t is the time in years.
1) In this situation we have that 
, the growth is 2.4%, then 
and 
and the equation is:
-------- Option A)
2) In this situation we have that 
, the decrease is 1.7%, then 
and 
and the equation is:
-------- Option B)
Answer:
The area of the circular cross section of the pipe is 
Step-by-step explanation:
we know that
The area of the circle (cross section of the pipe) is equal to
we have
----> the radius is half the diameter
substitute
