1) we find out the equation of the line.
Given a point (x₀,y₀) and the slope m, the slope-point form is:
y-y₀=m(x-x₀)
Data:
(3,4)
m=6
Therefore:
y-4=6(x-3)
y-4=6x-18
y=6x-18+4
y=6x-14
2) we find out y, when x=27
y=6*(27)-14
y=162-14
y=148
Answer: When x=27, then y=148.
Answer:
all but the middle
Step-by-step explanation:
did this on a test an got 100%
If you mean -1/3x try using y=3x
The correct answer is A) y = -1/5x + 1
To find the equation of the line, start by finding the slope. You can do this by using the slope formula below.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - -1)/(-5 - 10)
m = 3/-15
m = -1/5
Now that we have the slope, we can use it along with either point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 2 = -1/5(x + 5)
y - 2 = -1/5x - 1
y = -1/5x + 1
Answer:
C. 2.1 g/cm^3
Step-by-step explanation:
The density of an object is its mass per unit volume.
The formula for density is:
The object has a mass of 4.2 grams.
and a volume of 2 cubic centimeters
We substitute the known values into the formula to get:
We simplify to obtain:
