Hello!
$2.50Original price: $25
If sales tax is 10%, we can use multiplication to find the final price.
Convert 10% to a decimal:
10 / 100 = 0.1
Multiply 25 by 0.1 to solve:
25 × 0.1 = $2.5.

Answer:
4n+2 (B)
Step-by-step explanation:
Answer:
the answer is b
Step-by-step explanation:
because the value of terms are going up by 4 every time, so if you subtract 4 you get 2 and the position would be 0 making 2 the y-intercept and then slope is= rise/run and the equation is rising 4 units for every 1 unit moved, so the slope is 4/1 or 4. plug all of that into the equation and you get 4n + 2

What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
The triangles are congruent by SSS
JKL and MKL are the two triangles which sharing same segment KL.
A reflection is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points this set is called the axis or plane of reflection.
Rotation, then translation is also used in the given triangle.
Hence, reflection and rotation, then translation is the transformation(s) can be used to map one triangle onto the other.

Diego is attending UTEP and has completed some courses worth 3 credits and some course worth 4 credits. he has earned a total of 59 credits after completing 18 courses. How many courses worth 4 credits has Diego completed
Answer:
3 credit course = 13
4 credit course = 5
Step-by-step explanation:
Given that :
Total credits = 59
Total courses = 18
Let :
Number of 3 credit course = x ; number of 4 credit course = y
x + y = 18 - - (1)
3x + 4y = 59 - - - (2)
x = 18 - y
3(18 - y) + 4y = 59
54 - 3y + 4y = 59
54 + y = 59
y = 59 - 54
y = 5
x = 18 - 5
x = 13
3 credit course = 13
4 credit course = 5

(1) Today, the temperature in New York is -1 degree and is expected to rise 3 degrees per day. It's 6
degrees in Alaska and expected to fall 1 degree every 2 days.
Answer:
New York: m=3, b=-1, y=3x-1
Alaska: m=-1/2, b=6, y=-1/2x+6
2 days; 5 degrees
Step-by-step explanation:
In each case, m is the rate of change, the number of degrees per day that the temperature is changing. 1 degree per 2 days is 1/2 degree per day.
In each case, b is the given initial temperature.
The equation is y = mx + b, for the values of m and b that you fill in.
New York
m = 3, b = -1, equation: y = 3x -1
Alaska
m = -1/2, b = 6, equation: y = -1/2x +6
__
The graphs can be plotted by plotting the initial point on the y-axis, then finding another point based on the slope.
For New York, another point will be 1 unit right and 3 units up, at (1, 2).
For Alaska, another point will be 2 units right a 1 unit down, at (2, 5).
The lines intersect at the point (2, 5) corresponding to 2 days, 5 degrees.

In the table for the Thompsons, how much of their net worth is readily available for use?
A)$1,520
B)$10.770
C)$12.345
D)$14.320
lol the other guy was so confidently wrong it's actually A) 1,520
Thompson's net worth is US$ 37,742
What is addition?Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
Total Assets of the Thompson Family:
Total Assets = 1,520 + 9,250 + 112,340 + 12,800
Total Assets = 135,910
Total Liabilities of the Thompson Family:
Total Liabilities = 5,238 + 580 + 78,570 + 13,780
Total Liabilities = 98,168
Net worth of the Thompson Family
Net worth = Total Assets - Total Liabilities
Net worth = 135,910 - 98,168
Net worth = 37,742
Hence, Thompson's net worth is US$ 37,742

The graph represents the cost y (in dollars) to open an online gaming account and buy x games. Find the slope and the y-intercept of the line.
Answer:
Slope = 0.1 or 1/10
Y-int. = 15
Step-by-step explanation:
We have points (0,15), (3,45), (6,75), and (9,105).
slope is rise over run, or rise/run.
So, 9-3/105-45=6/60
now, simplify 6/60.
6/60=1/10 or 0.1
We already have the y-intercept, (0,15), because that's what intercepts the y-axis.
The slope of the line is 10.
The y-intercept of the line is 15.
Locate two points on the graph, choosing points whose coordinates are integers. We will use (3, 45) and (9, 105).
Starting with the point on the left, (3, 45) going from the first point to the second point, (9, 105).
The rise on the vertical leg of the triangle = (105 - 45) = 60
The run on the horizontal leg of the triangle = (9-3) = 6
Use the slope formula.
[tex]m = \frac{rise}{run}[/tex]
[tex]m=\frac{60}{6} =10[/tex]
The slope of the line is 10.
The y-intercept of a graph is the point where the graph crosses the y-axis. (Because a function must pass the vertical line test, a function can have at most one y-intercept.
the y-intercept of the line is 15.
Therefore, The slope of the line is 10 and the y-intercept is 15.

2. Given HS has endpoints H(5, -9) and S(-10, 11), find the coordinates of P so that P partitions HS in a ratio 2:3.
Point P?
Answer:
The coordinates of point P are (-1, -1)
Step-by-step explanation:
The coordinates of the partition point (x, y) of a line segment whose endpoints are (x1, y1) and (x2, y2) at ratio m: n are
x = [tex]\frac{mx2+nx1}{m+n}[/tex]y = [tex]\frac{my2+ny1}{m+n}[/tex]∵ P partitions segment HS in a ratio 2: 3
∴ P = (x, y)
∴ m = 2 and n = 3
∵ H = (5, -9) and S = (-10, 11)
∴ x1 = 5 and x2 = -10
∴ y1 = -9 and y2 = 11
→ Substitute them in the rule above to find x and y
∵ x = [tex]\frac{2(-10)+3(5)}{2+3}[/tex] = [tex]\frac{-20+15}{5}[/tex] = [tex]\frac{-5}{5}[/tex]
∴ x = -1
∵ y = [tex]\frac{2(11)+3(-9)}{2+3}[/tex] = [tex]\frac{22-27}{5}[/tex] = [tex]\frac{-5}{5}[/tex]
∴ y = -1
∴ The coordinates of point P are (-1, -1).
