which expressions are equivalent to 2 to the 6th power choose all that apply. please help

The solution to the system of equation is (7, 2)

Using the simultaneous equation:

5x + 3y = 41

2x + 3y = 20

using elimination method

Subtract equation 1 from 2 to have:

5x - 2x = 41 - 20

3x = 21

x = 21/3

x = 7

Substitute x = 7 into equation 1 to get y

5x + 3y = 41

5(7) + 3y = 41

35 + 3y = 41

5y = 41 - 35

3y = 6

y = 6/3

y = 2

Hence the solution to the system of equation is (7, 2)

Answer:

30

Step-by-step explanation:

1/2 x (a+b) x h = area

1/2 x ( 40 + x ) x 50 =  1750

1/2 (40 + x )= 1750/50

20 + 1/2x = 35

1/2 x = 35 - 20

x = 15 x 2

= 30

Answer:

Answer: No it isn't an equation. Not yet at least.

Step-by-step explanation:

Yes it might well do, but if it does, it needs something on the other side of wherever you put the equal sign.

6x - 7 is all you have so far and you have no idea what comes next. As it is, what you wrote is an algebraic expression.

Answer:

(5a²+4b³)³= 64b^9+240a^2b^6+300a^4b^3+125a^6

(2xy-1)³= 8x^3y^3−12x^2y^2+6xy−1

(3m-2n)= 0

(f+5)³=​ f^3+15f^2+75f+125

Step-by-step explanation:

(5a²+4b³)³  =  [tex]64b^{9} + 240a^{2} b^{6} + 300a^{4} b^{3} + 125a^{6}[/tex]

(2xy-1)³  = [tex]8x^3y^3 - 12x^2y^2 + 6xy - 1[/tex]

(3m-2n)  =  3m - 2n

Answer:

15 ft

Step-by-step explanation:

At 15 feet below the surface, the scuba diver did his safety stop.

The surface is the common region between two different mediums. Here in the question surface is the common region between seawater and above seawater.

Let us denote the values of descending by negative sign and rising by positive sign and we sum up all the values together.

∴ [ - 80 + 25 + (-12) + 52 ] feet.

= (-80 + 25 - 12 + 52) feet.

= - 15 feet.

So, at 15 feet below the surface the scuba diver dis his safety stop.

Answer:

D I dont know if im right though

Step-by-step explanation:

The system of equations are same and graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has infinitely many solutions.

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

The first equation is -3x + 3y = 12  be equation (1)  

y = x + 4   be equation (2)

Adding 3x on both sides , we get

3y = 3x + 12

Divide by 3 on both sides , we get

y = x + 4   be equation (3)

So , the equation ( 2 ) is same as equation ( 3 )

Now , the slope of the equation is m = 1 and the y intercept is b = 4

Hence , the equations have infinite solutions

Answer:

ok

1st one x=245°

2nd one x= 250

Step-by-step explanation:

hope its correct

hope u find it helpful

Answer:

x = 245 and x = 20

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5 , then

sum = 180° × 3 = 540°

Sum the interior angles and equate to 540

25 + 112 + 100 + 58 + x = 540

295 + x = 540 ( subtract 295 from both sides )

x = 245

---------------------------------------------------------------

5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540

25x + 40 = 540 ( subtract 40 from both sides )

25x = 500 ( divide both sides by 25 )

x = 20

Answer:

4.734 * 10^-5 miles

Step-by-step explanation:

Given that:

Distance between House to movie theater = 3 inches

Expressing the distance in miles :

Converting inch to miles

1 inch = 1.578 * 10^-5 miles

3 inches = (3 * 1.578*10^-5)

3 inches = 4.734 * 10^-5 miles

The answer is

[tex]y = - 4.4x + 6.8[/tex]

Answer: r = 1.69 inches

              h = 2.15 inches

Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.

Volume of a cone is directly proportional to radius and height:

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

They want the cones to hold the same volume of 9 cubic inches.

If height is 3:

[tex]9=\frac{1}{3}\pi r^{2}3[/tex]

[tex]\pi r^{2}=9[/tex]

[tex]r^{2}=2.864[/tex]

r = 1.69 inches

When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.

If radius is 2:

[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]

[tex]h=\frac{9(3)}{4 \pi}[/tex]

h = 2.15 inches

If radius is 2 inches, height of the cone is 2.15 inches.
