It is 20
I hoped i helped
hi! so i tried to solve this one for you, let me know if it is right..! have a great day
Answer:
The equation that represent x, the height of the sign is;
Step-by-step explanation:
Given that the area of the triangular yield is A square feet
and it has a base length of 3 feet.
also the height is represented by x;
Recall that the area of a triangle can be written as;
substituting the given;
Therefore, the equation that represent x, the height of the sign is;
The equation of the line is given as
A straight line equation is given in the form
where
is the gradient and
is the y-interest.
We need to rearrange
to make
the subject.
⇒ from here we can read the gradient and the y-intercept. The gradient,
and
.
<span>A line that is parallel to
will have the same gradient,
but different y-intercept. One example of equation of a line that is parallel to
is
</span>
A line perpendicular to another will have the opposite sign and be flipped
ex: slope is 4/5 the other lines slope will be -5/4
(-2,-1) (2,-3)
slope formula
y2-y1/x2-x1
-3-(-1)
____
2-(-2)
-3+1
___
2+2
-2
___
0
the slope of the perpendicular line is 0/-2 which is just 0
