(A-y)^2 +2y^3
If a=3 and y=-2

Integers.

The integers are the whole numbers, their opposites, and 0 . From the given numbers, −7 and 8 are integers. Also, notice that 64 is the square of 8 so −√64=−8 . So the integers are −7,8,−√64 − 7 , 8 , − 64 .

Answer:

150 is write answer

Step-by-step explanation:

mark me a brainlist

Answer:

y = 150

Step-by-step explanation:

Given that y varies inversely as x² then the equation relating them is

y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of variation

To find k use the condition y = 6 when x = 30 , then

6 = [tex]\frac{k}{30^2}[/tex] = [tex]\frac{k}{900}[/tex] ( multiply both sides by 900 )

5400 = k

y = [tex]\frac{5400}{x^2}[/tex] ← equation of variation

When x = 6 , then

y = [tex]\frac{5400}{6^2}[/tex] = [tex]\frac{5400}{36}[/tex] = 150

Answer:

1350 ft²

Step-by-step explanation:

First off, I notice that the triangle at the bottom can fit the slant at the top to make a perfect rectangle.

This will leave us with a rectangle. We can add up 4 and 5 for the sum of 9, making one side 9 inches.

5 + 4 = 9 in

We multiply 9 by 3 to get the actual length of that side

9 x 3 = 27 ft.

We multiply 16 and two-thirds by 3 to get the actual length of the other side

[tex]16\frac{2}{3}[/tex] x 3 = 50 ft.

To find the area of this rectangle we multiply length and width

50 x 27 = 1350 ft²

Answer:

D) 8x - 1

Step-by-step explanation:

Let's say that x = 5.  That would mean Amelia put 15(5) - 4 gallons of gas in her car, which equals 71 gallons.  She used 7(5) - 3 gallons driving to work, which is 32 gallons used.  71 - 32 = 39 gallons left.  

What else equals 39, you might ask?

8(5) - 1

40 - 1

39.

Answer:

D is the answer

Answer:

3x - 13

Step-by-step explanation:

The perimeter is just the distance around the triangle. We have all three sides, so we can just add them together to get the total distance.

(x-6) + (x+2) + (x-9)

Group:

x + x + x - 6 + 2 - 9

3x - 13

Step-by-step explanation:

3p²-7p-6

Now, 9-2=7 and 9×2=18

3p²-9p+2p-6

By taking out common, we get

3p(p-3)+2(p-3)

(3p+2)(p-3)

Answer:

(3p + 2)(p - 3)

Step-by-step explanation:

Answer:1 and 2

Step-by-step explanation:right on edge

Answer:

6 cm

Step-by-step explanation:

Let each side of the equilateral triangle be a.

Given, area of an equilateral triangle = 9√3 cm2

Area of an equilateral triangle = (√3)/4 × (Side)²

=> (√3)/4 × a² = 9√3

[tex] {a}^{2} = \frac{9 \sqrt{3} }{ \frac{ \sqrt{3} }{4} } = \frac{9 \sqrt{3} }{ \sqrt{3} } \times 4 = 9 \times 4[/tex]

=> a² = 36

[tex] \sqrt{ {a}^{2} } = \sqrt{36} \\ a = (+ - )6[/tex]

∴ Side = 6 cm  [taking positive square root because side is always positive]

Answer:

I think the two digit number formed would be

xy

seeing that x is on the tens place which is the second last place and y is on the ones place meaning it has to be the last value.

Answer:

the mean is 7.6 how you find the mean is u add all the numbers together then divide it by how many numbers are there

the median is 7

and the mode is 5

Step-by-step explanation:

Answer:

m = 65

Step-by-step explanation:

Given

- 13 = [tex]\frac{m}{-5}[/tex] ( multiply both sides by - 5 )

65 = m

Answer:

x = 125

Step-by-step explanation:

All triangle interior angles add up to 180 so:

x + 25 + 30 = 180

x + 55 = 180

x = 180 - 55

x = 125

Answer:

58.5

Step-by-step explanation:

0.65 decimal form

then times that by 90

then you got the answer 58.5

Answer:

y = 3x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{3}[/tex] x - 4 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{3} }[/tex] = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (3, - 1 ) into the partial equation

- 1 = 9 + c ⇒ c = - 1 - 9 = - 10

y = 3x - 10 ← equation of perpendicular line

Hi! I'm happy to help.

A rational number is a number that repeats, or stops.

First of all, 8/5, in fraction and decimal form (1.6), stops, So it is Rational.

Next, we have pi. This number, doesn't ever stop, or repeat. ( 3.1415926535 897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679...) So, pi, is Irrational.

Next, we have 0. This number stops, so it is Rational.

Next, we have[tex]\sqrt{1}[/tex], the square root of 1, is 1, because 1 squared is one. 1 stops, so it is Rational.

Next, we have 4.46466... This number doesn't stop, and it doesn't seem to repeat, so it is Irrational.

Next, we have -6. -6 stops, so it is Rational.

Finally, we have [tex]\sqrt{2}[/tex]. The square root of 2 is 1.41421356237...

This number doesn't stop, and doesn't repeat, so it is Irrational.

To sum it up: Number 1, 3, 4, and 6 are Rational, and Number 2, 5, and 7 are Irrational.

Answer:

y= -6/5x +3

Step-by-step explanation:

y = mx + b is the formula for every linear equation. m is the slope (comment if you don't know how to find the slope), and b is the y-intercept. You just have to find those terms and plug them in.

Answer:

It is C

Step-by-step explanation:

PM = QM

[tex]6x - 8 = 2x + 4 \\ 6x - 2x = 4 + 8 \\ 4x = 12 \\ x = 3[/tex]

Answer:

C.) x = 3

Step-by-step explanation:

The diagonals of a rectangle are equal, and QM and PM are both half of the two diagonals. You can now say that 2 * (6x - 8) = 2 * (2x + 4), meaning that 12x - 16 = 4x + 8, where you can add 16 on both sides, then subtract by 4x on both sides to get that 8x = 24. Now divide by 8 on both sides to get that x = 3.

Work Shown:

x = 0.212121...

100x = 21.212121....

Subtract the equations straight down. This means we subtract the left hand sides together, and the right hand sides are handled separately.

After those sets of subtractions, we are left with 99x = 21.

This solves to x = 21/99 when dividing both sides by 99 to isolate x.

Therefore, 21/99 = 0.212121...
