Y+3=2(x-1) im not so sure that i got the answer correct.

Vikentia [17]

So just try it for x=1 how many will get for y

y+3=2(x-1) for x = 1 will get y+3 =2(1-1) so y+3=2*0 so y+3=0 so y=-3

x=1
y=-3 so choice A.(1,-3) is right sure

hope this will help you

The variable z is inversely proportional to x. When x is 16, z has the value 0.875. What is the value of z when x= 21?

ziro4ka [17]

For $z$ and $x$ to be inversely proportional, there must be some constant $k$ such that

$zx=k$

Given that $z=0.875$ when $x=16$ , it follows that

$0.875\cdot16=k\implies k=14$

Then when $x=21$ , we have

$21z=14\implies z=\dfrac{14}{21}=\approx0.667$
