I don’t understand how to find the median of the triangle.
Answer:
9
Step-by-step explanation:
You can assume the two triangles have the same side ratio since their angles are equal. So 16/18 = y-1/y
Simplify to get...
16y = 18(y-1)
16y = 18y - 18
-2y = 18
y = 9

Step-by-step explanation:
A paper clip is just over 4 cm long. How many paper clips like this can be made from a straight piece of wire 10 meters long?
Answer:
25 Paper Clips
Step-by-step explanation:
100cm is equal to 1 meter. So to find the answer you would need to take the whole of the centimeter (100) and divide that by the paper clips length (4).
100/4 = 25
So, to form a straight line 10 meters long you would need 25 paper clips each 4cm long.
The number of 2,500 paper clips like the given paper clip can be made from a straight piece of wire that is 10 meters long.
What is multiplication?Multiplication is a type of mathematical operation. The repetition of the same expression types is another aspect of the practice.
For instance, the expression 2 x 3 indicates that 3 has been multiplied by two.
We can start by converting the length of the wire to centimeters since the length of the paper clip is given in centimeters:
10 meters = 10,000 centimeters
To determine the number of paper clips that can be made from the wire, we need to divide the total length of the wire by the length of each paper clip.
Number of paper clips = Total length of wire / Length of each paper clip
Length of each paper clip = 4 cm
Number of paper clips = 10,000 cm / 4 cm
Number of paper clips = 2,500
Therefore, the required number is 2500.

write the equation in vertex form: Vertex is (1.-3) and passes through the point (-1,5)
Answer:
y = 2(x - 1)² - 3
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (1, - 3), thus
y = a(x - 1)² - 3
To find a substitute (- 1, 5) into the equation
5 = a(- 1 - 1)² - 3
5 = (- 2)²a - 3 ( add 3 to both sides )
8 = 4a ( divide both sides by 4 )
a = 2
Thus
y = 2(x - 1)² - 3 ← in vertex form

Answer: $J/3 + $5
Step-by-step explanation:
Here is the complete question:
Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the $j fare among the 3 of them. Angela also paid a $5 tip. How much did Angela pay in total?
Write your answer as an expression.
Answer:
From the question, we are told that Angela shared a cab with her friends and when they arrived at their destination, they shared equally the $j fare among the 3 of them while Angela also paid a $5 tip.
The total number of friends are =3
The amount of fare = $ J
The fare is equally divided among the friends, therefore each friend will pay: $J/3
Angela paid $5 additional as a tip, therefore, her share will be: J/3 + 5
Therefore, Angela will pay $J/3 + $5

9514 1404 393
Answer:
6 days210 pagesStep-by-step explanation:
1. The number of pages (y) Amir reads in x days is ...
y = 35x
__
2. Jessie has been reading 1 more day than Amir, so an expression for the number of days Jessie has been reading is ...
x +1
The number of pages Jessie has read is ...
y = 30(x +1)
__
3. The system of equations is the two of these equations written together:
y = 35xy = 30(x +1)__
4. Using substitution to solve this, we find it convenient to substitute for y. Either equation provides an expression for y that can be substituted into the other equation. After substitution, the equation looks like ...
35x = 30(x +1)
__
5. We can subtract 30x from both sides and divide by 5 to solve.
35x -30x = 30(x +1) -30x
5x = 30x +30 -30x
5x = 30 . . . . simplified form after subtracting 30
x = 6 . . . . . . .result of dividing both sides by 5
y = 35x = 35·6 = 210
(x, y) = (6, 210)
__
6. It takes Amir 6 days to catch Jessie. At that time, both will have read 210 pages.

Using the segment addition postulate, find the value of x.
HI = 6x + 8
IJ = 2x - 4
HJ = 124
A) 15
B) 16
C) 9
HINT THAT I WAS GIVEN: The segment addition postulate states that the lengths of the pieces of a segment will add up to the length of the entire segment.
Answer:
A. 15
Step-by-step explanation:
HI and IJ are both segments in the line HJ so HI and IJ combined equal the total length of HJ. This means we can write an equation using HI and IJ and setting them equal to HJ.
6x + 8 + 2x - 4 = 124
next step is to combine like terms:
8x + 4 = 124
then, subtract 4 from both sides.
8x + 4 = 124
-4 -4
8x = 120
finally, divide both sides by 8.
8x/8 = 120/8
x = 15
since it is equal to x, 15 is your solution!

Which point is in the solution set of the system of inequalities
shown in the accompanying graph?
A. (0,4)
B. (2,4)
C. (-4,1)
D. (4,-1)
Answer: Option c.
Step-by-step explanation:
The dotted line means that the points in the line do not belong to the system, while the other line has all the points on the line.
Now, the point we are looking for must be a solution for both inequalities, so it must be in the region of the graph that is double shaded. (this would be the area at the left)
You now can take each point and see where it is located in the graph, if it is inside the double shaded area, then it is the correct answer.
Now, you will see that the only point that lies inside the double shaded area is the point (-4,1), so the correct option is c.
The point (-4, 1) is in the solution set of the system of inequalities.
An inequality shows the non equal comparison between two numbers or variables.
Given the inequalities as shown in the graph, the solution set of the inequalities is the point that lies on the dark shaded portion.
The dark shaded portion is the solution of the inequality.
From the graph the point (-4, 1) lies on the dark shaded portion.
Therefore the point (-4, 1) is in the solution set of the system of inequalities.
