Solve the system of equations.
2.5y + 3x = 27
5x – 2.5y = 5
What equation is the result of adding the two equations?
What is the solution to the system?
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
y = 6
Graph.
f(x)=2|x+2|+1
Use the Ray tool to graph the absolute value function.
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.

what does 30% mean in terms of money
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.

x^2+3xy=10
x=2y
9514 1404 393
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).

The Douglas family visits SeaLand and is charged $72.00 for 2 adult and 3 child tickets. The Williams family also visited SeaLand and was charged $78.00 for 1 adult and 5 child tickets. How much would it cost the Lopez family to go to SeaLand if they have 3 adults and 4 children?
Answer:
It would cost the Lopez family $102.00 to go to Sealand
Step-by-step explanation:
Assume that the cost of each adult ticket is $x and the cost of each child ticket is $y
∵ The adult's ticket costs $x
∵ The child's ticket costs $y
∵ The Douglas family is charged $72.00 for 2 adult and 3 child tickets
∴ 2x + 3y = 72 ⇒ (1)
∵ The Williams family was charged $78.00 for 1 adult and 5 child tickets
∴ x + 5y = 78 ⇒ (2)
Let us solve the system of equations to find x and y
→ Multiply equation (2) by -2 to make the coefficients of x equal in
values and different in signs
∵ -2(x) + -2(5y) = -2(78)
∴ -2x + -10y = -156 ⇒ (3)
→ Add equations (1) and (3) to eliminate x
∵ (2x + -2x) + (3y + -10y) = (72 + -156)
∴ -7y = -84
→ Divide both sides by -7 to find y
∴ y = 12
→ Substitute the value of y in equation (1) or (2) to find x
∵ x + 5(12) = 78
∴ x + 60 = 78
→ Subtract 60 from both sides
∴ x + 60 - 60 = 78 - 60
∴ x = 18
∴ The cost of each adult ticket is $18 and the cost of each child ticket
is $12
∵ Lopez family has 3 adults and 4 children
∴ The cost of the tickets = 3(18) + 4(12) = 54 + 48
∴ The cost of the tickets = 3(18) + 4(12) = 102
∴ It would cost the Lopez family $102.00 to go to Sealand

Results for kiona sells tickets to the school play. The ratio of student tickets to adult tickets sold is 4:3. Kiona sold 280 tickets altogether . How many student tickets did Kiona sell?
Answer:
160
Step-by-step explanation:
It is given that, the ratio of student tickets to adult tickets sold is 4:3. Let students tickets is 4x and adult tickets is 3x.
Total no of tickets = 280
ATQ,
4x+3x=280
7x = 280
x = 40
Students ticket = 4x
= 4(40)
= 160
So, 160 students ticket is sold by Kiona.

If m ∥ n and the slope of line m is 3, what is the slope of line n? A. 13 B. –13 C. –3 D. 3
Answer:
3
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.

Clare was solving an equation, but when she checked her answer she saw her solution was incorrect. She knows she made a mistake, but she can’t find it. Where is Clare's mistake?
Answer:
The Second Step.
Step-by-step explanation:
We are given the original equation:
[tex]12(5+2y)=4y-(5-9y)[/tex]
In her first step, Clare distributed both sides:
[tex]72+24y=4y-5-9y[/tex]
There are two errors:
First, the product of 5 and 12 is 60 and not 72.
Second, on the right-hand side of the equation, the negative must be distributed to all terms. Hence, the correct result should be:
[tex]\displaystyle 60 + 24y = 4y - 5 + 9y[/tex]
Instead of what she had obtained.
