Answer:

(-11, -12)

Step-by-step explanation:

we need one variable to x out

on the note of x, lets cancel out the xs

6x+3y=-102

3x+y=-45 < same as 6x+2y-90

6x+3y=-102

6x+2y=-90

y=-12

substitute y in

3x-12=-45

3x=-33

x=-11

(-11, -12)

Please give brainliest :)

a manufacturer of bicycle parts requires that a bicycle chain have a width of 0.3 inch with an absolute deviation of at most 0.0

quester [9]

Answer:

$|w-0.3| \leq 0.0003$

And solving we got:

$-0.0003 \leq w-0.3 \leq 0.0003$

$0.3-0.0003 \leq w \leq 0.3+0.0003$

$0.2997 \leq w \leq 0.3003$

Step-by-step explanation:

For this case we can define the following notation:

$W$ represent the width

And we want a maximum error of 0.0003 so we can set up the following equation:

$|w-0.3| \leq 0.0003$

And solving we got:

$-0.0003 \leq w-0.3 \leq 0.0003$

$0.3-0.0003 \leq w \leq 0.3+0.0003$

$0.2997 \leq w \leq 0.3003$
