Step-by-step explanation:

add like terms

30 + 7k = 100

100-30 = 70

70 divided by 7k = 10

k = 10

4. add the z's together

2z - 6 -2 = -10

+ 6 + 2

-10 will be -2 now since we dragged the -6 and -2 to the other side

2z = -2

z = -1

5. 3.2x - 1.7x = 1.5x

1.5x + 5.5 = 10

10 would be 4.5 since we dragged 5.5 to the other side so it would be 10 - 5.5

3.2x = 5.5

x = 1.71875

3/4x - 1/4x = 2/4x

14 - 3 = 11

2/4x = 11

x = 22

Use the sliders to change the values of a, b, and cin
the sine function. Which equation has a maximum at
(Pi/4, 3) and a minimum at (pi/4, -3)

Answers

y=-3 cos(2x) is the equation has a maximum at (4π , 3) and a minimum at (4π , -3)

What is Trigonometry?

The study of correlations between triangles' side lengths and angles is known as trigonometry.

The sine function's parameters, a, b, c, and d, must be adjusted using the sliders.

Now, Finding the equation with a maximum at (4π , 3) and a minimum at (4π , -3) is necessary.

Thus, Setting the values for the slider requires setting a to -3, b to 2, and c to 0.

Hence, The solution, y=-3 cos (2x), should match the equation obtained from the sliders.

In the morning, Marco sold 12 cups of lemonade for $3. By the end of the day, he had earned $9. How many cups of lemonade did he sell in all?

Kaycee wrote the proportion StartFraction 12 over 3 EndFraction = StartFraction 9 over c EndFraction for this situation. Identify the error and give two ways to write the proportion correctly.

Answers

Answer:

Marco earned $2.25.

Step-by-step explanation:

1. If Marco sold 12 cups of lemonade for 3$, we would divide 12 cups and how much he earned from the 12 cups (3$). 12/3 = 4

2. By the end of the day, Marco earned $9. So, 4 cups = 1$. To break it down, 1$ = 100 cents and 100 cents divided by 4 is 25 cents. Cups to Cost. ( 4 : 1 ) and/or ( 1 : 0.25 )

3. 8 cups = 2$ plus 1 cup (0.25) = 2.25.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Answer:

Kaycee did not keep lemonade and dollars in corresponding positions in the ratios of the proportion. The proportion should be 12/3=c/9 or it could be written 3/12=9/c. Dollars should be in the same position and cups should be in the same position across ratios.

Here is a system of equations:
-7x + 3y = -65
-7x + 10y = -135
Write an equation that results from subtracting the two equations.

Answers

Answer:

y = -10

Step-by-step explanation:

(-7x+3y) - (-7x +10y) =-65 -(-135)

-7x + 3y + 7x -10y = 70

-7y = 70

y = -10

The equation that results from subtracting - 7x + 3y = - 65 and

- 7x + 10y = - 135 is 7y = - 70.

What are simultaneous equations?

We know two simultaneous equations have a unique solution when they intersect at a point,

when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.

Given, a system of equations - 7x + 3y = - 65 and - 7x + 10y = - 135.

Subtracting the first equation from the second we get,

- 7x + 10y = - 135

(-) - 7x + 3y = - 65

_________________

Negative sign gets distributed

- 7x + 10y = - 135

+ 7x - 3y = + 65

_________________

7y = - 70

y = - 70/7

y = - 10.

So, the value of x is -7x +10×(-10) = - 135.

- 7x - 100 = - 135.

- 7x = - 135 + 100.

- 7x = - 35.

x = 7.
