Answer: 40
Step-by-step explanation:
-5/4is left of the line and opposite is right side of line
Answer:
y = 6x +1
Step-by-step explanation:
To write the slope-intercept form equation for a line, you need to know the slope and the y-intercept. These can be found from their respective formulas.
__
<h3>slope</h3>
The slope of a line between points (x1, y1) and (x2, y2) is given by the formula ...
m = (y2 -y1)/(x2 -x1)
For points (-1, -5) and (0, 1), the slope is ...
m = (1 -(-5))/(0 -(-1)) = 6/1
m = 6
<h3>y-intercept</h3>
The y-intercept is the value of y where the line crosses the y-axis. That axis is where x = 0. There is a formula that can be used to find the y-intercept from the slope and a point on the line:
b = y -mx . . . . . y-intercept of line with slope m through point (x, y)
However, one of the given points is already the y-intercept: (0, 1). It tells you b=1.
<h3>equation</h3>
The slope-intercept equation is ...
y = mx +b
y = 6x +1
Let
x--------> the speed of the girl in step
y--------> the speed of the escalator in step
d------> the distance between ground and floor.
we know that
when the girl is going up on escalator
----> equation 
when the girl is going down on escalator
-------> equation 
Adds equation and equation
--------> equation 
Time to climb (in step) with y=0 (escalator standing still)
-----> equation 
Substitute equation in equation
therefore
the answer is
The area of any shape is measured in sq.cm (if the dimensions are measured in cm), sq.m (if the dimensions are measured in m), sq.km (if the dimensions are measured in km). If the unit of dimensions is not given then we write it at sq. units or unit squared.
A shape is covered by 40 unit squares, that means the area of the shape is 40 sq.units
