what number must you add to complete the square ?

X^2+22x=9

Answer:

-80

Step-by-step explanation:

We have: -6 = [tex]\frac{x}{8}[/tex] + 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.

The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.

Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:

-6 - 4 = [tex]\frac{x}{8}[/tex] + 4 - 4  ⇒  -10 = [tex]\frac{x}{8}[/tex]

Then, multiply by 8 on both sides:

-10 * 8 = [tex]\frac{x}{8}[/tex] * 8  ⇒  x = -80

Thus, x = -80.

Hope this helps!

Answer:

x = -80

Step-by-step explanation:

Alright let's get started!

Rewrite the equation as ,

x/8 + 4 = -6

Move all terms not containing x to the right side of the equation.

(Subtract 4 from both sides of the equation.)

x/8 = -10

Multiply both sides of the equation by 8 to get rid of the denominator,

8 * x/8 = -10 * 8

8 cancels out on the left side,

x = -80

Answer:

75 gallons of water

180 gallons of premium anti-freeze

Step-by-step explanation:

X + Y = 255

X = 255 - Y

0.85Y = 0.6(255)

0.85Y = 153

Y = 180

X = 255 - 180

X = 75

Answer:

Option C, x = 6

Step-by-step explanation:

Step 1:  Divide both sides by -8

[tex]-8x = -48[/tex]

[tex]-8x / -8 = -48/-8[/tex]

[tex]x=6[/tex]

Answer:  Option C, x = 6

Answer:

x = 6

Step-by-step explanation:

Let's solve your equation step-by-step.

−8x = −48

Step 1: Divide both sides by -8.

−8x /−8  =  −48 /−8

x = 6

Based on the calculations, the measure of arc LP is equal to 17°.

In Mathematics and Geometry, a perpendicular bisector is a segment, or ray that bisects a line segment exactly into two (2) equal halves and forms an angle that has a magnitude of 90 degrees at the point of intersection.

Based on the definition of a perpendicular bisector, we can logically deduce that the two larger arcs have the same measure;

mLM = mNP

8x - 56 = 5x + 22

8x - 5x = 22 + 56

3x = 78

x = 78/3

x = 26°

Since the sum of all the four (4) arcs form a full circle, we would set up an equation and equate it to 360 degrees;

mLM + mNP + mMN + mLP = 360°

8x - 56 + 5x + 22 + 39 + mLP = 360°

8(26) - 56 + 5(26) + 22 + 39 + mLP = 360°

152 + 152 + 39 + mLP = 360

mLP = 360 - 343

mLP = 17°

Answer:

Common ratio = -8

Step-by-step explanation:

The common ratio of the geometric sequence will be - 8.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The geometric sequence is,

⇒ 3/8, -3, 24, - 192,

Now,

Since, The geometric sequence is,

⇒ 3/8, -3, 24, - 192,

Hence, The common ratio = Second term ÷ First term

                                         = - 3 ÷ 3/8

                                         = - 3 × 8/3

                                         = - 8

Thus, The value of common ratio = - 8

Answer:

23 degrees

Step-by-step explanation:

We see that arc LM is 67 degrees. By definition, that means that the central angle <LPM also equals 67 degrees.

We also see that arc LMO is just a semicircle, which means that it is 180 degrees, by definition (because a whole circle is 360 degrees and a semicircle is just half a circle). In addition, angle MPN has that little square in its angle, which means that it is 90 degrees. By definition, its arc MN is also equal to 90 degrees. Then:

Arc LMO = arc LM + arc MN + arc ON

180 = 67 + 90 + arc ON

Solving, we get that arc ON = 180 - 67 - 90 = 23 degrees. By definition, that means the corresponding central angle <NPO is also equal to 23 degrees.

Notice that angles NPO and KPL are vertical angles, which means that by definition, they are equal in degree measure. So, since <NPO = 23, then <KPL = 23. Arc KL is the corresponding arc of <KPL, so by definition, arc KL is also 23 degrees.

Thus, the answer is 23 degrees.

Answer:

5 =  (x - 2)^2

Step-by-step explanation:

sqrt(5) = x - 2

Square each side

(sqrt(5))^2 = (x - 2)^2

5 =  (x - 2)^2

Okay this is easier than you think!

if (x - 2) equals [tex]\sqrt{5}[/tex]

then that means  [tex](x-2)^{2}[/tex] = [tex]\sqrt{5} ^ {2}[/tex]

Anything under a square root when sqared, is itself

[tex]\sqrt{5} ^{2} = 5[/tex]

so the value of [tex](x-2)^{2}[/tex] = 5

Answer:

Positive Slope-A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises. Another words, the line goes up.

Negative Slope-A line with a negative slope is a line that is trending downward from left to right. In other words, the line's rise to run ratio is a negative value. Or the line goes down

Undefined Slope- An undefined slope is the slope of a vertical line! The x-coordinate never changes no matter what the y-coordinate is.

Zero Slope-A zero slope is just the slope of a horizontal line. The y-coordinate never changes no matter what the x-coordinate is.

Final answer:

Given a sphere with a volume of 904.78 cm3, we find the radius to be approximately 6.13 cm, and the area of the largest cross-section, a circle, turns out to be approximately 118.08 cm2.

Explanation:

If the sphere has a volume of approximately 904.78 cm3, we can start by calculating the radius of the sphere using the volume formula for a sphere:

V = (4/3)πr3

Solving for r:

r = &Sqrt[3]{(3V)/(4π)} = &Sqrt[3]{(3×904.78 cm3)/(4π)} ≈ 6.13 cm

The largest cross-section of the sphere will be a circle with the diameter equal to the diameter of the sphere, hence the area A of this circle will be:

A = πr2 = π×(6.13 cm)2 ≈ 118.08 cm2

Therefore, the approximate area of the largest cross-section of the sphere is 118.08 cm2, which is not listed among the provided options, implying a possible typo or error in the options. Option closest to the calculated area is B) 113.1 cm2.

Since you know the value of x, you can substitute/plug it into the equation to find the value of y:

y = 2x + 5      Plug in 1 into "x" since x = 1

y = 2(1) + 5

y = 7

When x = 1, y = 7 -->  (x, y) = (1, 7)       Your answer is #4

Answer:

TS = 11.

Step-by-step explanation:

Consider triangles UTO and UCS.

m < C = m < UTO (Given)

< U is common to both triangles.

Therefore triangles UTO and OCS are similar.

So  corresponding sides are in the same ratio and:

5 / (TS + 4) = 4/ (7+5)

5 * (7 + 5) = 4(TS + 4)

TS + 4 =   5*12 / 4

TS + 4 = 15

TS = 11.

Answer: C

Step-by-step explanation:

The arc length, s, equals the radius, r, times the central angle, θ, given in radians. (In shorthand, s=r⋅θ.) If r=5 cm and θ=6 radians, the arc length is 5 cm⋅6=30 cm. If r=7 cm and θ=5 radians, the arc length is 7 cm⋅5=35 cm. If r=9 cm and θ=4 radians, the arc length is 9 cm⋅4=36 cm. An angle of 180∘ is π radians, or about 3.14. If r=10 cm, the arc length is 10 cm⋅3.14=31.4 cm. Of these choices, the longest arc is 36 cm.

Answer:

504 in³

Step-by-step explanation:

this is a rectangular prism and the volume formula is v = l * h * w

so now

v = l*w*h

v= 6*8*12

v = 576 inch³

that's not the answer, that's the volume for whole thing but there is a gap and we have to subtract it from the whole volume. you can look at the option and say it's 504 inch³ from common sense. here is the work:

the gap has 2 inch length, 6 inch width and 6 in height.

v = l*h*w

v = 6 * 2 * 6

v= 72 inch

now subtract the gap volume from total volume so

576 - 72 = 504 in³
