The line from the point to its reflection should be perpendicular.If we imagine a line from (5,7) to (2,2), it would have a slope of (2-7)/(2-5) = 5/3.
For that line to be perpendicular to y=-2/5x+6, their slopes should be each other's negative reciprocals.
-2/5 negative reciprocal is 5/2, which is not equal to our calculated 5/3, so (2,2) cannot be the reflected point. Evan was wrong.
Q1-74: AB have slope 6/5, C has -5/6, D 6/5, E -5/6 again.
You can isolate r to one side of the equation by dividing by adding three, dividing by s, multiplying by a and you get:
r=a(3+k)/s
Answer: option iii
The perimeter of an isosceles triangle with congruent sides of 16.2 cm and a third side half that length is 16.2+16.2+8.1 = 40.5 cm
Explanation:
The perimeter of an isosceles triangle with congruent sides of 16.2 cm and a third side half that length is 16.2+16.2+8.1 = 40.5 cm
First side is = 16.2 cm
Second side is = 16.2 cm
Third side = half of 16.2 = 8.1 cm
The perimeter of an isosceles triangle with congruent sides of 16.2 cm and a third side half that length is 16.2+16.2+8.1 = 40.5 cm
So what you do is evaluate g(2) then plug that value in for x in f(x)
g(2)=2^2-6(2)-7
g(2)=4-12-7
g(2)=-15
now
f(-15)=-15+8
f(-15)=-7
f(g(2)=-7
Answer:
Zero
Step-by-step explanation:
Because integers are equal in magnitude but opposite in sign, therefore they will cancel out each other leaving zero as answer.
