Line passes through (-5,3) and (-6,-1). Line B passes through (3,-2) and (2,-7). Are the lines parallel? Explain.
Answer:
No they are not parallel.
Step-by-step explanation:
You have to figure out the slopes of each set of points. For (-5,3) and (-6,-1) the slope is 4 and for (3,-2) and (2,-7) the slope is 5. You can only have parallel lines if the slope is same and the y- ints are different. Here the slopes aren't same.
Sorry If im wrong. Hope this helps!
The two given lines are not parallel.
What is the slope of a line which passes through points ( p,q) and (x,y)?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
Its slope would be:
[tex]m = \dfrac{y-q}{x-p}[/tex]
Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.
We are given that;
The points= (-5,3) and (-6,-1), (3,-2) and (2,-7)
Now,
For line A, let’s use (-5, 3) and (-6, -1) as the two points. Plugging these values into the formula, we get:
m = (-1 - 3) / (-6 - (-5)) = -4 / -1 = 4
So, the slope of line A is 4.
For line B, let’s use (3, -2) and (2, -7) as the two points. Plugging these values into the formula, we get:
m = (-7 - (-2)) / (2 - 3) = -5 / -1 = 5
Hence, the slope of line B is 5.
Since the slopes of line A and line B are not equal (4 ≠ 5),
Therefore, by the slope the answer will be they are not parallel.

Rick buys 18 apples for $13. How much would it cost to buy 24 apples?
Answer:
$33.23
Step-by-step explanation:
If 18 apples cost $13, this means that each apple costs 1.38461538. To find the cost of 24 apples, multiply that decimal number by 24. You will get 33.2307692308. You can round this to 33.23.

Answer: Choice A. f(x) = sqrt(x-1)
===========================================
Explanation:
The parent function is y = sqrt(x) and the left-most edge of this curve is at (0,0).
The graph shows the left-most point at (1,0) instead.
This means we've shifted everything 1 unit to the right, or you can think of the xy axis being shifted 1 unit to the left while the square root curve stays still (giving the illusion the curve moves).
If we shifted the xy axis 1 unit to the left, then each input x becomes one smaller, so each input is now x-1
That's why we go from y = sqrt(x) to y = sqrt(x-1)
You can use a graphing calculator to confirm this, or you can create a table of values to generate the points on this new blue curve.

Answer:
its $63.96
Step-by-step explanation:
Using the formula (b) and replacing the given values:
Sale Price = Original Price - Amount Saved. So,
Sale Price = 79.95 - 15.99
Sale Price = $63.96 (answer).
This means the cost of the item to you is $63.96.
You will pay $63.96 for a item with original price of $79.95 when discounted 20%.
In this example, if you buy an item at $79.95 with 20% discount, you will pay 79.95 - 15.99 = 63.96 dollars.
Answer:
$63.96
Step-by-step explanation:
$79.95 = 100%
The jacket is on sale for 20% off, therefore it is 100% - 20% = 80% or 0.8
0.8 x $79.95 = $63.96

The school sold 300 tickets to the theatre performance. They sold adult tickets for $9 each and student tickets for $6 each. They made a total of $2, 190. How many students were in attendance?
PLEASE HELP! I need to show work
Answer:
170 students were attending
Step-by-step explanation:
use a system of equations:
[tex]\left \{ {{x+y=300} \atop {9x+6y=2190}} \right.[/tex]
let x be the adults and y be the students
[tex]\left \{ {{-9(x+y=300)} \atop {9x+6y=2190}} \right.[/tex] multiply the top equation by -9 and add the two systems together to cancel out x. you are then left with:
[tex]-3y=-510[/tex]
divide both sides by -3 to leave y alone:
[tex]\frac{-3y}{-3}=\frac{-510}{-3}[/tex]
that would leave you with:
y=170

The circle below represents one whole.
What percent is represented by the shaded area?
%
Answer:
25%
Step-by-step explanation:
check
1/4 * 100% = 25%
The region represented by the shaded area has 25% and is 1/4th of the total circle.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
The formula to calculate the area of the circle is given as πr², where r is the radius of the circle.
In the given figure the total area of the circle is πr². The shaded region is one-fourth of the total area of the circle.
Total area = πr²
Shaded area = ( 1 / 4 )πr²
The percentage of the shaded area will be calculated as
Shaded area = ( 1 / 4 )πr²
Shaded area = ( 0.25 )πr²
To convert it into a percentage multiply by 100.
Shaded area = ( 0.25 x 100 )πr²
Shaded area =25% πr²
Put πr² as the total area.
Shaded area =25% of Total area.
Therefore, the region represented by the shaded area has 25% and is 1/4th of the total circle.
