Answer:
y = - 1/2x + 5
Step-by-step explanation:
y = 2x – 6 slope = 2
Perpendicular line slope = -1/2
for (4 , 3) y = mx + b y = 3, x = 4, m = -1/2
b = y - mx = 3 - (-1/2) x 4 = 5
equation: y = - 1/2x + 5
Answer:
7.
Step-by-step explanation:
-10 /(3 + 2) + 9
= -10 /5 + 9
= -2 + 9
= 7.
Answer:
Hello,
First equation is false
Second equation is true
Step-by-step explanation:
1)
(4,-3) is a point of the line y=4x-19 since
-3=?4*4-19
-3=-3
2)
(4,-3) is not a point of the line y=1/4x-2 since
-3=? 1/4*4-2
-3=? 1-2
-3≠-1
I have written that because it is difficult for me to understand
"the negative reciprocal of the slope of the first"
the negative reciprocal of 4 should be -1/4.
Equation y=1/4x-2 is false.
Answer:
1) 81.64 ft 2) 12.56 in
Step-by-step explanation:
a radius is a line <em>halfway</em> through the circle starting in the middle... a diameter is double that, or a line that goes <em>all the way </em>through the circle
you are working with diameter
in order to find the circumference of a circle using diameter, the equation is
C (circumference) = pi x d (diameter)
in order to find the circumference of a circle using radius, the equation is
C = 2 x pi x R (radius)
