Answer:
y = 0.5x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 1, y = 0.5, then
k =
=
= 0.5, hence
y = 0.5x ← equation of variation
check the picture below.

as you may already know, tan⁻¹ function has a range of (π/2, -π/2), and therefore it will give us the negative counterpart angle, however, the positive one we can get it by going the other way, 360 - θ.
I am unable to see the picture ( if you have one) try re uploading and I can help
Hello,
f(x)=x+8
g(x)=x²-6x-7
f(g(x))=f(x²-6x-7)=x²-6x-7+8=x²-6x+1
f(g(2))=2²-6*2+1=4-12+1=-8+1=-7
Answer A
Answer: 7/8
Step-by-step explanation:
If you turn 1 3/4 into a improper fraction the equation is 7/4 times 1/2. 7•1=7 and 4•2=8 so your answer is 7/8.
