Answer:
y = (7/2)x -20
Step-by-step explanation:
The given line is in slope-intercept form, so you can read its slope from the equation.
y = mx + b . . . . . m is the slope; b is the y-intercept
y = -(2/7)x + 9 . . . . . . has slope -2/7
The perpendicular line will have a slope that is the negative reciprocal of this, so will be ...
m = -1/(-2/7) = 7/2
We can use this and the given point to write the equation in point-slope form.
y = m(x -h) +k . . . . . . line with slope m through point (h, k)
We have m = 7/2, (h, k) = (4, -6) so the equation is ...
y = (7/2)(x -4) -6
y = (7/2)x -20
Answer:
$484.97.
Step-by-step explanation:
For a minimum amount of wall/fencing the garden has to be a square.
That would make each side of the garden = √48 dollars.
So the smallest amount would be √48 * 3 * 20 +√48 * 10
= $484.97.

The right answer is: f[g(4)] = 45
Step-by-step explanation:
First of all, we have to find g(4)
So,
Now to find f(g(4)) we will put the value of function g on 4 in place of x in function f
Hence,
The right answer is: f[g(4)] = 45

The area of a triangle is A= 1/2bh. Plugging in the values you know, 30= 1/2*12*h.
Solving for h,
30= 1/2*12*h
30= 6h
h=5
The height of the triangle is 5 units.
