Answer:
y = -2x + 27
Step-by-step explanation:
Firstly, we shall need to reform the given line equation;
y-7 = 1/2 ( x + 2)
y - 7 = x/2 + 1
y = x/2 + 1 + 8
y = x/2 + 8
Comparing this with y = mx + c
where m is the slope, then the slope of the line is 1/2
Since the line we are looking for has a slope perpendicular to this line, it means that the product of their slopes is -1
m1 * m2 = -1
1/2 * m2 = -1
m2 = -2
So we want an equation with slope -2 passing through (6,15)
we use the point slope method here;
y-y1 = m(x-x1)
y-15 = -2(x-6)
y-15 = -2x + 12
y= -2x + 12 + 15
y = -2x + 27
Hello!
A(r) is a function. It takes a value of r, and from that calculates the value A. In this case, it takes the value of a radius, and <u>depending on what that value is</u>, it calculates the area.
A(3) would therefore represent the area based off of a radius of 3.
Hope this helps!
–x + y = –3 (a)
3x + 2y = 9 (b)
Lt's eliminate y , by multiplying a) by -2
-2(–x + y) = -2(–3) → +2x - 2y = +6 (c). Now add (c) to (b)
+2x - 2y = +6 (c).
3x + 2y = 9 (b)
----------- --------
5x + 0 = 15 and x = 15/5 and x = 3
To find y, plugin the value of x in any of the equation, sat (a):
–x + y = –3 (a) → -3 + y = -3; y = -3+3 → y = 0
So the solution is (3,0) Answer C
