Answer:
y=3/4x
Step-by-step explanation:
Answer:
-8y+6x=-8
Step-by-step explanation:
Can't promise this is 100% correct, but I tried.
y = −2x + 11
If the two equations are graphed, at what point do the lines representing the two equations intersect?
(4, 3)
(3, 4)
(9, 11)
(11, 9)
Answer:
Hence, the two equations intersect at:
(4,3)
Step-by-step explanation:
We are given:
A pair of equations:
3x − y = 9
y = −2x + 11
now, on graphing these equations.
as we can clearly see from the graph the two lines intersect at (4,3)
Hence, the two equations intersect at:
(4,3)
Answer:
40 square metres
Step-by-step explanation:
The shaded region is of a triangle, whose area is denoted by: A = (1/2) * b * h, where b is the base and h is the height.
Since the left figure is a square with side lengths 10, we know that the height of the triangle is also 10 metres. The right figure is a rectangle with length 4. Since the total base length of the entire figure is 18 and the base of the square is 10, then the width of the rectangle is 18 - 10 = 8 metres.
This width is also the base of the triangle, so b = 8.
Now plug these values into the equation:
A = (1/2) * b * h
A = (1/2) * 8 * 10 = (1/2) * 80 = 40
The area is 40 square metres.
Answer:
40 m²
Step-by-step explanation:
Area of any triangle:
½ × base × height
base = 18 - 10 = 8
height = 10
Area:
½ × 8 × 10
40 m²
