Answer:
y=30
Step-by-step explanation:
y-8=22
Add 8 on both sides
y=30
Answer:
x = 1 and y = - 4
Step-by-step explanation:
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line goes through.
Here the line passes through (1, - 4) with x- coordinate 1, thus
x = 1 ← equation of vertical line
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line goes through.
Here the line passes through (1, - 4) with y- coordinate - 4, thus
y = - 4 ← equation of horizontal line
Answer:
The area is 6.4cm, the perimeter is 12cm
Step-by-step explanation:
The formula to calculate area is
Where is the height
And for the perimeter, you just add up the size of the sides.
