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:

This is because angles inscribed in a semicircles are 90 degrees (BCA)

The tanget of that circle is also a 90 degree angle to the diameter (ABD)

Therefore they're both 90 degrees

The measure of angle BCA must equal the measure of angle ABD should be that angle should be  inscribed in a semicircles that are 90 degrees,

In terms of geometry, an inscribed angle refer to the angle that should be created in the interior of a circle  at the time when two chords should be intersect on the circle. It can also be refer to the angle subtended at a point on the circle via two given points on the circle.

Also, angle should be  inscribed in a semicircles that are 90 degrees,

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.

Step-by-step explanation:

The measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees

The point where two lines meet or intersect is known as an angle.

If L is in the interior of ∠JKM, then:

∠JKL + ∠LKM = ∠JKM

Given the following parameters

m∠JKL=56.4° and m∠JKM=82.5°

Required angle

m∠LKM

From the expression above:

m∠LKM = ∠JKM - ∠JKL

m∠LKM = 82.5 - 56.4

m∠LKM  = 26.1 degrees

Hence the measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees

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:

slope: 7

y-intercept: 1/2

Step-by-step explanation:

Put it into the form y = mx + b where m is the slope and b will be the y-intercept. (For example, in the equation y = 3x + 2 the slope is 3 and the y-intercept is 2).

[tex]0=1-2y+14x\\2y=1+14x\\2y = 14x+ 1\\y = 7x + 1/2[/tex]

So you know that m = 7, so the slope is 7

and

b = 1/2, so the y-intercept is 1/2.
