Answer:
y = x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 2 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
The line crosses the y- axis at (0, 1) ⇒ c = 1
y = x + 1 ← equation of line
Answer:
3/49
Step-by-step explanation:
The area of a rectangle is found using A = l*w. At the park, it measures A = 49*25 = 1,225 yards².
On the map the area is A = 3*25 = 75 inches².
The ratio of the area of the map to the area of the park is found by placing 75 ovre 1,225. Then simplify if possible.
Answer:
0.6 liters paint will he need to cover
Step-by-step explanation:
Direct Variation states that the two quantities are related in such a way that increase in one quantity results in a corresponding increase in the other quantity and vice versa, then such type of a variation is called a direct variation.
i.e
It is given that the painter uses 1.2 liters of paint to cover
This is the situation of Direct Variation: As less area cover, less liters of paint.
Let two quantities are x and y;
x represents the area covered by painter
y represents the liters uses by the painter.
Then, the ratio of any two values of y is equal to the corresponding value of x.
i.e,
or
therefore, from the given information we have;
Simplify:
Therefore, 0.5 liters paint required by the painter to cover the area
