Which equation has the same solution as x2 + 16x + 9 = -3?

Answers

Answer 1

Answer:

Step-by-step explanation:

x² + 16x + 9 = - 3

x² + 16x + 12 = 0

D = 16² - 4(1)(12) = 208

√D = 4√13

[tex]x_{1}[/tex] = ( - 16 - 4√13 ) ÷ 2 = - 8 - 2√13 ≈ - 15.21

[tex]x_{2}[/tex] = ( - 16 + 4√13 ) ÷ 2 = 2√13 - 8 ≈ - 0.79

Including a 7% sales tax, an inn charges $125.19 per night. Find the inn's nightly cost before tax is added.

Answers

The inn's nightly cost before tax is added is $23.54

Taxes are prices added on top of goods and services

Let the normal price be x

Price including tax = x + 0.07x (note that the tax iss 7%)

Given that Price including tax = $125.19, then;

$125.19 = x + 0.07x

Find the value of x

125.19 = 1.07x

Swap

1.07x = 125.19

x = 125.19/1.07

x = $23.54

This shows that the inn's nightly cost before tax is added is $23.54

Step-by-step explanation:

[tex] - 9 + x \leqslant 4 \\ x \leqslant 4 + 9 \\ x \leqslant 13[/tex]

Hello!

For this type of problem, treat the “less than or equal to” sign as an equal sign!

So, -9+x=4

Now, it is as simple as solving for “x” just like a regular algebra problem. Add 9 to both sides to get “x” by itself:

-9+x+9=4+9

Now you have:

X= 13

Plug the “less than or equal to” sign back into the equation:

X ≤ 13

13. In ADGE,DG = 8,GE = 17, and DE = 15. What is the length of DF? Round to the nearest hundredth.

Answers

Answer:

Step-by-step explanation:

The trick is not to get all caught up in Pythagoras. There is a much simpler way to do it. Find the area of the triangle two different ways. DG and DE are at right angles. That is one way to find area. The other is use the height (DF) and multiply that by the hypotenuse GE.

DG*DE/2 = GE * DF/2            Multiply both sides by 2

DG*DE = GE * DF

DG = 8

DE = 15

GE = 17

8*15 = 17* DF

120 = 17 * DF                         Divide by 17

120/17 = DF

DF = 7.06

Length = 12

Midpoint = 1

Step-by-step explanation:

to find the length u cancount from left to right of the segment and u can see that it is 12 units long. To find the mid point just take half of the the length, which is 6, and count that many units from either side of the segment. you'll stop at 1 do that is the mid point of the graph.

find EF given E (-7, -2) and B (11, 3)
how do i solve this?

Answers

Answer:

EF ≈ 18.68

Step-by-step explanation:

Based on the info I am given I believe they are asking for the distance between E and F (i think you wrote B by mistake). (d = distance)

d =√ (x2 - x1)² + (y2 - y1)²   -->   (this is the distance formula)

d =√ (11 - (-7))² + (3 - (-2))²

d =√ (18)² + (5)²

d =√ 324 + 25

d =√ 349

d ≈ 18.68

what is the answer for this Evaluate 3|-3|.

Answers

Answer: 9

Concept:

Here, we need to know the idea of absolute value.

The absolute value of a number or integer is the actual distance of the integer from zero, in a number line.

There are no negatives in absolute value. So in practice "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive.

Solve:

Given

3 |-3|

Expand absolute value sign, which means making [-3] positive

= 3 × (3)

Simplify by multiplication

= [tex]\boxed{9}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

3|-3| = 9

Because absolute value sign |-3|
That mean 3
3*3 = 9
So answer is 9
