Answer:
15(3x-1)
Step-by-step explanation:
45x = 5*3*3*x
15 = 5*3
The common terms are 5*3
We can factor out 5*3 or 15
5*3*3*x - 5*3*1
15( 3*x -1)
15(3x-1)
At hour 9 the river is 18 feet deep.
At hour 18 the river is 21 feet deep.
From 9 to 18 hours is 9 hours difference.
From 18 to 21 feet is a 3 foot difference.
The average rate of change is the change in depth divided by the change in time:
3 feet / 9 hours = 0.3 feet per hour. ( Rounded to the nearest tenth)
Answer:
one sixth of 7.5 pounds is 1.25, so 7.5 minus the rotten 1.25 is 6.25.

The slope intercept form of the line whose points are (1,5) and (-2,-4) is y=3x+2.
Given two points of a line (1,5) and (-2,-4).
We have to form an equation in slop intercept form.
Equation is relationship between two or more variables which are expressed in equal to form.Equations of two variables looks like ax+by=c.
Point slope form of an equation is y=x+mc where m is slope of the line.
From two points the formula of equation is as under:
(y-
)=
*(x-
)
where
are the points.
Putting the values of
=1,
=-2,
=5 and
=-4.
y-5=(-4-5/-2-1)*(x-1)
y-5=-9/-3*(x-1)
y-5=3(x-1)
y-5=3x-3
y=3x-3+5
y=3x+2
Hence the slope intercept form of the line having points (1,5)(-2,-4) is y=3x+2.
