Answer:

y = (-4/5)x - 4

slope = m = -4/5

y-intercept = -4

Step-by-step explanation:

slope-intercept form: y = mx + b

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. Isolate the variable, y.

First, subtract 4x from both sides:

4x (-4x) + 5y = -20 (-4x)

5y = -20 - 4x

Next, divide 5 from both sides to isolate the y:

(5y)/5 = (-20 - 4x)/5

y = (-4x - 20)/5

y = (-4/5)x - 4

y = (-4/5)x - 4 is your answer.

An assembly line inspector inspected 340 machine parts. 323 of the parts passed inspection. What percent of the machine parts di

tester [92]

Answer:

5% did not pass inspection

Step-by-step explanation:

Given

$Inspected= 340$

$Passed = 323$

Required

Determine the percentage of parts that didn't pass inspection.

First, we need to calculate the number of those that didn't pass inspection.

$Failed = Inspected - Passed$

$Failed = 340 - 323$

$Failed = 17$

Next, we calculate the percentage as follows:

$\% = \frac{Failed}{Inspected} * 100\%$

The above formula is derived by dividing the number of parts that didn't pass inspection by the total machine inspected, then multiplied by 100%

So:

$\% = \frac{17}{340} * 100\%$

$\% = \frac{17 * 100\%}{340}$

$\% = \frac{1700\%}{340}$

$\% = 5\%$

<em>5% did not pass inspection</em>
