To find out the area of a triangle just pretend that it’s a square and when u get ur answer, divide it by half. So for example of the area of a square is 20 then the area of a triangle that fits inside that square would be 10.
15% of 1200 = 180
1200-180= 1020
to find the cost price use the discounted price and take it away from the original, then use the profit take away the discounted price.
1020-120=900
the cost price of the watch is Rs. 900
Equation of the graph is y = –9x + 360.
Solution:
Take any two points on the line.
Let the points are (40, 0) and (0, 360).
Slope of the line:
m = –9
The slope is –9.
y-intercept is the point where the line intersects with the y-axis.
y-intercept = 360
b = 360
Slope-intercept form:
y = mx + b
y = –9x + 360
Equation of the graph is y = –9x + 360.
Answer:
A.
