Solve the equation using the zero-product property. (2x − 8)(7x + 5) = 0 x = –2 or x = 7 x = 4 or x = x = 4 or x = x = –4 or x =
aliya0001 [1]

(2x-8)(7x+5)=0\iff2x-8=0\ \vee\ 7x+5=0\\\\2x-8=0\qquad\text{add 8 to both sides}\\2x=8\qquad\text{divide both sides by 2}\\\boxed{x=4}\\\\7x+5=0\qquad\text{subtract 5 from both sides}\\7x=-5\qquad\text{divide both sides by 7}\\\boxed{x=-\dfrac{5}{7}}

What's something that could go wrong if you use numbers that are not precise?​
Strike441 [17]

Answer:

There are a lot of things that can go wrong, especially when we have an error in a measure that we use a lot of times (each time, that error increases).

For example, you think that each meter of fence costs $5, but the actual price is $5.30, and you need 40 meters, then you think that you may need to pay:

40*$5 = $200

But they will actually charge you:

40*$5.30 = $212.

Now this is a small example, now let's go to medicine, suppose that you want to trait cancer with radiation in a pacient, if you do not use precise measures for the dosage of radiation or the measures of the tumor, you may cause a lot of damage in the patient. (And similar cases if you want to give some medication and the numbers that you use are not precise, you may overdose the patient)

So the use of precise numbers may be critical in a lot of scenarios.

Whats the measure of the angles (SHOW YOUR WORK so I can understand)
evablogger [386]

Answer:

Angle DEB: 52

Angle ADB: 30

Angle CBE: 52

Angle BEC: 38

Step-by-step explanation:

Angle DEB = 52 because triangles' angles must add up to 180. Angle ADB is 30 because it is complementary to angle BDE. Angle CBE is 52 because angle BEC is complementary to BED which is 52 degrees to BEC is 38 degrees. since the angles add up to 180, and C is 90, CBE is 52. Finally, BEC is 38 because it is complementary to BED.

You have $25 to buy 6 fishing lures. Write and solve an inequality that represents the prices you can pay per fishing lure.
Rus_ich [418]

We are given that we have $25 to pay for 6 fishing lures.

We can make an equality for this as follows:

Suppose price of one fishing lure is x dollars.

So we will use unitary method to find price of 6 fishing lures.

Price of 6 fishing lures = 6 * ( price of one fishing lure) = 6* x = 6x

Now we only have 25 dollars with us, so the price of 6 fishing lures has to be less than or equal to 25 dollars.

So creating an inequality,

6x\leq25

Now in order to find price for one fishing lure, we have to solve this for x.

Dividing both sides by 6 we have,

x\leq\frac{25}{6}

Converting to decimal,

x\leq4.167

Answer : The price of one fishing lure must be less than or equal to $4.167
