Daute bought two types of meat that is pork and tuna from the supermarket. He bought total of 5 lbs of meat, if he bought
lbs of pork. How much lbs of tuna did Daute bought?
A. directly proportional 1/x = 1/y
The radiusof <span> (x^2−6x)+(y^2−10y)=−18 </span>is 4
Answer:
<u>y</u><u> </u><u>=</u><u> </u><u>1</u><u>4</u><u>/</u><u>3</u><u> </u><u>and</u><u> </u><u>2</u>
<u>x</u><u> </u><u>=</u><u> </u><u>-</u><u>1</u><u>3</u><u>/</u><u>3</u><u> </u><u>and</u><u> </u><u>1</u>
<u>(</u><u>-</u><u>1</u><u>3</u><u>/</u><u>3</u><u>,</u><u> </u><u>1</u><u>4</u><u>/</u><u>3</u><u>)</u><u> </u><u>and</u><u> </u><u>(</u><u>1</u><u>,</u><u> </u><u>2</u><u>)</u>
Step-by-step explanation:
<u>f</u><u>o</u><u>r</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>(</u><u>a</u><u>)</u>
make x the subject of the formular:
<u>f</u><u>o</u><u>r</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>(</u><u>b</u><u>)</u>
<u></u>
substitute for x as 5 - 2y in equation (b):
therefore,
substitute for all values of y in equation (c):
<u>f</u><u>o</u><u>r</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>1</u><u>4</u><u>/</u><u>3</u><u>:</u>
<u>f</u><u>o</u><u>r</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>2</u><u>:</u>
