Answer:

  (x, y) = (-2, -1) or (2, 1)

Step-by-step explanation:

Substitute for x in the first equation:

  (2y)^2 +3(2y)y = 10

  10y^2 = 10

  y^2 = 1

  y = ±1

  x = 2y = ±2

Solutions are (x, y) = (-2, -1) or (2, 1).

80*

75*

120*

Step-by-step explanation:

both angle 1 and 2 for the first image have the same value as  the other angle of 80* because it is a set of parallel lines and one line going through it.

1 on the next set of images is 75* because is is an alternate exterior angle.

2 of the last set of images is 120* because it is same side interior angles.

Step-by-step explanation:

We can use the Ray tool to graph the absolute value function f(x) = 2|x+2| + 1, which helps us visualize the function by plotting specific points on the coordinate plane.

1. Begin by understanding the structure of the absolute value function f(x) = |x|. The absolute value function takes any input x and returns the positive value of x, making it symmetric concerning the y-axis.

2. In the given function f(x) = 2|x+2| + 1, the "2" in front of the absolute value affects the vertical scale, while the "+2" inside the absolute value causes a horizontal shift of 2 units to the left.

3. Start plotting points on the coordinate plane. To determine the behavior of the graph, consider a few x-values.

  - When x = -4, we have f(-4) = 2|-4+2| + 1 = 2| -2| + 1 = 2(2) + 1 = 4 + 1 = 5. So, we have the point (-4, 5).

  - When x = -2, we have f(-2) = 2|-2+2| + 1 = 2| 0| + 1 = 2(0) + 1 = 1. So, we have the point (-2, 1).

  - When x = -1, we have f(-1) = 2|-1+2| + 1 = 2| 1| + 1 = 2(1) + 1 = 3. So, we have the point (-1, 3).

  - When x = 0, we have f(0) = 2|0+2| + 1 = 2| 2| + 1 = 2(2) + 1 = 5. So, we have the point (0, 5).

  - Continue this process for other values of x to obtain more points.

4. Plot all the points on the graph and connect them smoothly. Remember to maintain symmetry concerning the y-axis due to the absolute value function.

5. The resulting graph will have a "V" shape, with the vertex at the point (-2, 1). The line will extend upward on both sides, following a steep slope with a vertical stretch of 2.

6. Label the axes and any other relevant points to complete the graph.

By following these steps and utilizing the Ray tool, you can accurately graph the given absolute value function f(x) = 2|x+2| + 1.

Let me = the minutes we are searching for.

(-2.5)/11_1/4 = 1/m

Rewrite 11_1/4 as 45/4.

(-2 5)/(45/4) = 1/m

Cross-multiply to find m.

45/4 = -2.5m

Divide both sides by -2.5.

45/4 ÷ -2.5 = m

Answer :

Option A) 84°

Step-by-step explanation:

Its an equilateral triangle ( since DE and EF = 5)

So they have the same angles as well ..

which means angle D = 48° and angle F = 48°

angle D + angle F + angle E = 180° (angle sum property)

48° + 48° + angle F = 180°

96° + angle F = 180°

angle F = 180° - 96°

= 84°

Answer:

84°

Step-by-step explanation:

It's an equilateral triangle (since DE and EF = 5)

And they have the same angles as well.

Which means the angles D=48° and angle F=48° angle D+ angle F+ angle E=180° (angle sum property) 48°+48°+ angle F=180°, 96°+ angle F=180° angle F=180°-96°=84°.

Answer:

Step-by-step explanation:

When 2 lines are parallel, they have the same slope. Since m║n, the slope of m will be equal to the slope of n.

The required slope of line n which is parallel to line m is 3. Option D is correct.

Given that,
If m ∥ n and the slope of line m is 3, what is the slope of line n is to be determined.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The property of line state that, when lines are parallel to each the than the angle of inclination or slope of all the parallel lines are equal.
So, in given condition Line m is parallel to line n implies the slope of line m and n are equal.

Thus, the required slope of line n which is parallel to line m is 3.

Answer:

8x = 32

x = 4

y = 6

Step-by-step explanation:

2.5y + 3x = 27

5x – 2.5y = 5

_____________

8x = 32 (equation obtained after adding the two equations)

x = 32/8

x = 4

Plug x = 4 in 2.5y + 3x = 27

2.5y + 3*4 = 27

2.5y + 12 = 27

2.5y = 27 - 12

2.y5= 15

y = 15/2.5

Answer:

Explanation below.

Step-by-step explanation:

Let's say for example you have 100 dollar or euros, or whatever you work with in your country. 30% of 100 equals 30.

If they ask you for example 30% of 250 dollar/euro, it is 250/100 * 30, which equals 75.

If they say there are sales that go up to 30%, all you do is as follows;

1) You calculate how much money 30% is. [Look above]

2) You distract the 30% FROM the original price.

Example; A shirt costs 300 dollar/euro, but there's a sale of 30% on it.

30% of 300 = 100

300-100 = 200

The shirt costs 200 dollar/euro.

Answer:

11 ; 12°

Step-by-step explanation:

3x + 28 + 2x - 10 + 5x + 52 = 180

10x = 180 - 70

x = 11

m∠C = 2(11) - 10 = 12°

Answer:

Angle ACB = 12°

Step-by-step explanation:

All angles in a triangle always add up to 180°, which gives us an equation to solve for x:

3x + 28 + 5x + 52 + 2x -10 = 180

Combine like terms

10x + 70 = 180

Subtract 70 from both sides

10x = 110

Divide both sides by 10

x = 11

Now we know the value of x, we need to just plug it in to angle ACB's given value:

2(11) - 10 = Angle ACB

22 - 10 = Angle ACB

12 = Angle ACB
