Answer:
x = 5
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = bh ( b is the base and h the height )
Here b = 8 and h = 15 , then
A = × 8 × 15 = 4 × 15 = 60 cm²
The area of the rectangle is also 60 cm² , then
length × breadth = 60 , that is
12x = 60 ( divide both sides by 12 )
x = 5

Answer:
Y = -1/2 x
Step-by-step explanation:
To write the equation in slope intercept form
Y = mx + c
C is y-intercept
the graph is passing through centre. That means y-intercept is zero.
so C=0
To find m which is slope,
rise = 10
run= -20
So
