How many solutions does the system have? <br> y=−2x+2<br> y=x^2−3x
s2008m [1.1K]
Y=-2x+2 and y=x^2-3x.

If there are solutions the x and y values are equal so we can say y=y:

x^2-3x=-2x+2  add 2x to both sides

x^2-x=2  subtract 2 from both sides

x^2-x-2=0  now factor...

x^2+x-2x-2=0

x(x+1)-2(x+1)=0

(x-2)(x+1)=0

So there are two solutions, when x=-1 and 2

Using y=-2x+2 we can find the corresponding y values for the solutions...

y(-1)=-2(-1)+2=2+2=4, y(2)=-2(2)+2=-4+2=-2 so the two solutions are the points:

(-1,4) and (2,-2)

A client's inventory is recorded at $600,000 and is comprised of 1,000 items. The auditors examined a sample of items with a rec
KonstantinChe [14]

Based on the calculation done below, the estimated audited value for inventory is $540,000.

<h3>How is the estimated audited value for inventory calculated?</h3>

This can be calculated using the following formula:

E = (T / S) * A ……………………… (1)

E = Estimated audited value for inventory = ?

T = Total value of inventory recorded by client = $600,000

S = Value of inventory sampled by the auditor as recorded by the client = $100,000

A = Audited value of the inventory sampled = $90,000

Substituting the values into equation (1), we have:

E = ($600,000 / $100,000) * $90,000

E = 6 * $90,000

E = $540,000

Therefore, the estimated audited value for inventory is $540,000.

5(12 + m) = 100 find m
Llana [10]

Answer:

8

Step-by-step explanation:

1. multiply 5 and 12 to get 60

2. multiply 5 and m to get 5m

3. the equation would be 60 + 5m = 100

4. next, subtract 60 on both sides

5. your equation so far is 5m = 40

6. then divide 5 on both sides

7. then you have your answer m = 8
