I need help please :/

Part (a)

Plug in y = 0 and solve for x. Use the zero product property

y = x(x+3)(x-2)

0 = x(x+3)(x-2)

x(x+3)(x-2) = 0

x = 0 or x+3 = 0 or x-2 = 0 .... zero product property

x = 0 or x = -3 or x = 2

The three roots or zeros are x = 0 or x = -3 or x = 2

================================================

Part (b)

The roots of the graph are: x = -2, x = 1, x = 3. Each root is where the graph crosses or touches the horizontal x axis.

Note how x = 0 is found in part (a), but not found here. This is one example where the graphs don't match. Another would be x = -3 is in part (a), but not here.

So that's why the graph does <u>not</u> match with the function in part (a)

The average salary for a doctorate is 39,000 less than twice that of someone with a bachelor's degree. Combined, a people (one w

tester [92]

Answer:

doctorate salary: d = $71,000

bachelor salary: b = $55,000

Step-by-step explanation:

doctorate salary: d

bachelor salary: b

relationship between b and d: d = 2b - $39,000

Unfortunately, your "1 + 126,000" could not be correct. I'm going to assume that the total of the two salaries is $126,000. If that's the case, then:

bachelor salary + (2 times bachelor salary less $39,000) = $126,000. In symbols,

b + 2b - $39,000 = $126,000

Consolidating the 'b' terms results in 3b - $39,000 = $126,000, and so:

3b = $126,000 + $39,000 = $165,000

Dividing both sides by 3 yields the bachelor salary: b = $55,000

Then the doctoral salary is 2b - $39,000 = 2($55,000) - $39,000, or $71,000.

Check: Does b + (2b - $39,000) = $126,000? Yes.

Then the doctoral salary is d = $103,000, and the bachelor salary $29,000
