Answer:

3. B.

1. 3551.

Step-by-step explanation:

3. For two equations to have infinite solutions, the equations must be the same.

y = -5x + 6

5x + y - 6 = 0

Multiply the whole thing by 2.

10x + 2y - 12 = 0

B.

1. Michelle rides roller coasters 3 times and plays the super swing 5 times, which means that A = 3 and B = 5.

Marty rides the roller coasters 5 times and plays the super swing 1 time. That means C = 5 and D = 1.

So, your answer will be 3551.

Hope this helps!

How to get answer by JKismyhusbandbae: To get the answer you would multiply

Pi(3.14) times Radius which is R otherwise 80 square times H which is height 1.3.

It will need around 26138.050... and more it is not a repeating decimal I just simplified it.

Which of the following is the equation for the graph shown?
serious [3.7K]

The Answer is A

Explanation:

The standard form equation for an ellipse is:

(x - h)² / a² + (y - k)² / b² = 1

So looking at the picture above you can see that the center of the ellipse is at the origin which is (0;0) making both h and k zero.

It is then observed that the x-intercepts are at 12 meaning a=12 and y- intercepts are at approximately square root of 95 which is 9.746... which are 'k'

So you can conclude by saying that:

x²/12² + y²/(sqrt of 95)² = 1

then giving you the answer of A which is:

x²/144 + y²/95 = 1

What is the value is of x?<br><br> A)0<br><br> B)25<br><br> C)4<br><br> D)7
iogann1982 [59]

We know that these two angles are equal to each other (There is the "congruent" sign) so we can set them equal to each other and solve for x

3x - 17 = 25 - 3x

(3x + 3x) - 17 = 25 + (-3x + 3x)

6x + (- 17 + 17) = 25 + 17

6x/6 = 42/6

x = 7

Hope this helped!

Find the solution to the system of equations. You can use the interactive graph below to find the solution. y=-4x-3 y=-2x+1 x= y
Mama L [17]

Answer:

(-2, 5)

Step-by-step explanation:

I will assume that your system is

y = -4x - 3

y = -2x + 1

Multiplying the second equation by -2 results in

 y = -4x - 3

-2y = 4x - 2

combining these two equations eliminates x temporarily:

-y = -5, so that y must be 5.

Substituting 5 for y in the second equation, we get:

5 = -2x + 1, or

4 = -2x, which results in x = -2

and so the solution is (-2, 5)

Find the area of the circle with the given radius or diameter. Use = 3.14. d=13
leva [86]
Area of a triangle = \pi r^{2}
r = diameter/2
so area = pi * (13/2)^2
= 3.14*6.5*6.5 = 132.665
