of more than 1 dot is on an “up and down” line then it’s not a function
Answer:
16
Step-by-step explanation:
Hope this helps sorry if I'm wrong
Z=kx, 30=8k, so k=30/8=15/4 and z=15x/4, so when x=4, z=15.
x=1001+75.55x
Simplify
x=<span><span>75.55x</span>+1001</span>
Subtract
x−<span>75.55x</span>=<span><span><span>75.55x</span>+1001</span>−<span>75.55x</span></span>
−<span>74.55x</span>=1001
Divide
<span><span>−<span>74.55x/</span></span><span>−74.55 = </span></span>
<span><span><span><span><span>1001/<span>−74.55</span></span><span><span>your answer is:</span></span><span>x=<span>−<span>13.42723</span></span></span></span></span></span></span>
The correct way is to plug in the answer back into the equation and see if it results in the correct solution.
