Answer:
(-3, -6)
Step-by-step explanation:
Coordinate = (x-axis, y-axis)
=(x,y)
identify value of coordinate A at x-axis before y-axis
x-axis of A is in the middle of -2 and -4, thus it is -3
y-axis of A when refer to graph is -6
thus answer is (-3,-6)
Answer:
d)
true
Step-by-step explanation:
- x - 4y = - 10
x + 4y - 10 = 0
a)
3 + 4×2 - 10 = 0
3 + 8 - 10 = 0
11 - 10 ≠ 0 (false)
b)
- 3 + 4×3 - 10 = 0
12 - 3 - 10 = 0
12 - 13 ≠ 0 (false)
c)
false
d)
true
Answer:
Perimeter of the rectangle = 8 x +4
Length of the rectangle = 12 units.
Step-by-step explanation:
Let the width of the rectangle as 'x' units.
So, length of the rectangle is 2 more than 3 x.
We can set up expression for length as 3 x+2.
Now, perimeter is sum of all side lengths of the rectangle.
So, perimeter = x+x+3 x+2 +3 x+2
Combine like terms,
Perimeter = 8 x+4
Now, it is given perimeter is 36cm
So,
8 x+4=36
Subtract both sides 4
8 x=32
Divide both sides by 8
x=4
So, width of the rectangle =4
Length =3(4) +2=14
