Step-by-step explanation:

The system of equations 6x+4y=14 and 9x+6y=c are linear equations

The value of c that makes the system have infinitely many solutions is 21

The system of equations are given as:

6x+4y=14

9x+6y=c

Divide through the second equation by 3

3x + 2y = c/3

Multiply through by 2

6x + 4y = 2c/3

Subtract the first equation from the above equation

6x - 6x + 4y - 4y = 2c/3 - 14

Evaluate the differences

2c/3 - 14 = 0

Add 14 to both sides

2c/3 = 14

Multiply by 3/2

c = 21

Hence, the value of c that makes the system have infinitely many solutions is 21

The volume of the prism is 2 cm³.

Option B is the correct answer.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The volume of the prism:

= Base area x height

Now,

Base area = 4 x 1 = 4 cm²

Height = 1/2 cm

Using the velocity formula, it is found that the acceleration is of a = 9.8 m/s².

It is given by the initial velocity plus acceleration multiplied by time, that is:

v(t) = v0 + at.

In this problem, we have that v(0) = 0, t = 2, v(2) = 19.6, hence:

v(t) = v0 + at.

19.6 = 0 + 2a.

2a = 19.6.

a = 19.6/2.

a = 9.8 m/s².

The acceleration is of a = 9.8 m/s².

Step-by-step explanation:

     We will subtract the apples used from the original pounds of apples to solve this question. First, I will turn all units into eighths to subtract.

8 1/2 -> 8 4/8

1/2 -> 4/8

3 1/8 -> 3 1/8

Step-by-step explanation:

bc ur an L. ur whole life is an L

Step-by-step explanation:

120° + 20° + x = 180° ( sum of interior angle. of triangle is 180°)

140° + x = 180°

x = 180° - 140°

x = 40°

Now

y + x = 180° ( supplementary angle)

y + 40° = 180°

y = 180° - 40°

y = 140°

The angle measure of y is 140°.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

The three angles of a triangle are 120°, 20° and x.

And we know,

the sum of the interior angle of the triangle is 180°.

120° + 20° + x = 180°

140° + x = 180°

x = 180° - 140°

angle measure of x = 40°

Now:

Here, x and y are supplementary angles.

Supplementary angles are two angles whose measures add up to 180°

y + x = 180°

y + 40° = 180°

y = 180° - 40°

y = 140°

Therefore, the value of y is 140°.

Answer:

Equation: y + 1 = -2(x - 0)        OR        y + 3 = -2(x - 1)

Slope: -2

Y-intercept: (0, -1)

Step-by-step explanation:

First, create an equation in point-slope form using ONE point. Using (0,-1):

y - y1 = m(x - x1)

y + 1 = m(x - 0)

Then, use both points to find slope:

[tex]\frac{y2-y1}{x2-x1} =m[/tex]

[tex]\frac{-1-(-3)}{0-1}[/tex]

[tex]\frac{2}{-1}=m=-2[/tex]

Then, plug the slope into the equation and rewrite in the form of y=mx+b:

y + 1 = (-2)(x - 0)

y + 1 = -2x

y = -2x - 1

-1 = b      OR      (0, -1)      

Final answers:

Equation: y + 1 = -2(x - 0)      OR       y + 3 = -2(x - 1)

Answer:

72 points

If you can get 8 each time that would be the same as doing 8+8+8...

The problem also states that if he hits it 8 times in a row you add 8 more points.

64+8=72

There are 72 points Brady receive if he hits the target 8 times in a row.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Alex is playing a game where he gets 8 points 8 every time his ball hits the target.

And, He gets an extra 8 points every time his ball hits the target 8 times in a row.

Hence, Number of points Brady receive if he hits the target 8 times in a row is,

⇒ 8 x 8 + 8

⇒ 64 + 8

⇒ 72

Thus, There are 72 points Brady receive if he hits the target 8 times in a row.

The value of the given function is as follows sin a = 3/5, cos a =4/5 and sec a = 5/4.

By right-angled triangle, we can find the trigonometric function from the sides of the triangle.

sin x = perpendicular/ hypotenuse

cos x = base/ hypotenuse

sec x = hypotenuse /base

From a triangle ABC of base 4, perpendicular 3, and hypotenuse 5, we get

sin a = perpendicular/ hypotenuse

        = 3/5

cos a = base/ hypotenuse

         = 4/5

sec a = hypotenuse /base

        = 5/4

Hence, the value of the given function is as follows sin a = 3/5, cos a =4/5 and sec a = 5/4.

Answer:

{x,y} = {7,-9/2}

Step-by-step explanation:

System of Linear Equations entered :

 [1]           25-x=-4y

 [2]           3x-2y=30

Equations Simplified or Rearranged :

  [1]    -x + 4y = -25

  [2]    3x - 2y = 30

Graphic Representation of the Equations :

   4y - x = -25        -2y + 3x = 30  

Solve by Substitution :

// Solve equation [1] for the variable  x

 [1]    x = 4y + 25

// Plug this in for variable  x  in equation [2]

  [2]    3•(4y+25) - 2y = 30

  [2]    10y = -45

// Solve equation [2] for the variable  y

  [2]    10y = - 45

  [2]    y = - 9/2

// By now we know this much :

   x = 4y+25

   y = -9/2

// Use the  y  value to solve for  x

   x = 4(-9/2)+25 = 7

Solution :

{x,y} = {7,-9/2}

Answer:

x=7, y=-4.5 or (7, -4.5)

Step-by-step explanation:

Hi there!

We are given the following system of equations:

25-x=-4y

3x-2y=30

Before we do anything, let's move our x and y values to one side, while keeping the numbers on the other side

So for 25-x=-4y, start by adding 4y to both sides

25-x=-4y

  +4y  +4y

_____________

25 + 4y - x = 0

Now subtract 25 from both sides

4y - x = -25

Now the system is this:

4y-x=-25

3x-2y=30

We can solve this equation by substitution, where we solve one of the equations for one of the variables, and then use the expression that the variable is equal to, in order to find the value of the other variable. Then, once the value of that variable is found, use that value to find the value of the first variable.

Start with 4y-x=-25

Subtract 4y from both sides

-x=-4y-25

Now multiply both sides by -1

x=4y+25

Substitute 4y+25 as x in 3x-2y=30

3(4y+25)-2y=30

Multiply

12y+75-2y=30

Simplify

10y+75=30

Subtract 75 from both sides

10y=-45

Divide both sides by 10

y = -4.5

Now substitute -4.5 as y in x=4y+25

x=4(-4.5)+25

Subtract

x= -18 +25

x= 7

The answer is x=7, y=-4.5. As a point, it's (7, -4.5)
