To find the roots, you must set the function equal to zero and then solve for x. 
For f(x)=4x^2 + 5x -21  
The zeros of the function are: x=-3, x=7/4
Hope this helps!

Give an example of an equation with an infinite number of solutions. Then make one change to the equation so that it has no solu
mrs_skeptik [129]
Two equations with infinite solutions would look the exact same. Example:
y=mx+b
y=mx+b
Example 2
y=2x+5
y=2x+5
For an equation with no solution they would have the same slope but different y intercepts. An equation with same slope and same y intercepts would have infinite solutions.

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>
