Answer:
-4
Step-by-step explanation:
simplify both sides of the equation, subtract 4n from both sides, add 16 to both sides, divide both sides by -3
The equation of a line is usually written in what's called <em>slope-intercept form</em>.
Slope-intercept form is written as y = mx + b where m = slope and b = the y-intercept.
The slope of a line can easily be found just by using two points on the line. The slope is equal to the rise over the run, or the difference in y over the difference in x, between the two points.
The y-intercept of the line is the point at which it intersects the y-axis. (The vertical axis.) All points on the y-axis have an x coordinate of 0, so we would then add or subtract the rise and run to a point on the line until we reached x = 0.
Fortunately, we already have this point! It's (0, -2)!
Now we just need to put our slope and y-intercept into the equation.
And to test if a point is on this line, just plug in the x and y coordinates and see if the equation is true!
Answer:
Distance of Sun and Mercury = 58,000,000 km.
In Scientific notation, it would be: 5.8 × 10⁷ Km
Diameter of a human hair = 0.0025 cm
In scientific notation, it would be: 2.5 × 10⁻³ cm
Before Comparison, we need to bring to or vice-versa, so we can easily calculate then, here, we will go from cm to Km.
2.5 × 10⁻³ × 10⁻⁵ Km = 2.5 × 10⁻⁸
Now, we can compare the values,
5.8 × 10⁷ Km > 2.5 × 10⁻⁸
[ reason. - power of smaller number is in negative, it means, it is denominator, which would be very small as compared to other ]
Answer:
The equation is:
Step-by-step explanation:
Given the endpoints of a side of a rectangle
Finding the slope
Using the point-slope form of a line equation
substituting the values m = -1 and the point (1, 6)
Thus, the equation is:
Set up a proportion!
40 minutes / 5 holes = m minutes / 20 holes
Cross multiply.
800 = 5m
m = 160.
It will take him 160 minutes to dig 20 post holes.
Good luck Fabian!
Hope this helps
