Use midpoint theorem :- The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also 'half of the length of the third side'.
So,
2x = ½ (x + 9)
2x = ½(x) + ½(9)
2x - ½x = 9/2
3/2x = 9/2
x = 9/3
x = 3

Convert 39/4 into a mixed number.
Answer: The answer is 9 3/4.
Step-by-step explanation: When converting an improper fraction to a mixed number, the first step to take is figure out how many times the denominator goes into the numerator. The number 4 goes into 39
9 times(4 x 9 = 36). The remainder 3 becomes the numerator of the denominator 4, therefore 39/4 converted to a mixed number is 9 3/4.
Answer:
9 3/4
Step-by-step explanation:
Solve for y.
3y+5=4y−2
y=−7
y = 1
y = 3
y = 7
Answer:
y = 7
Step-by-step explanation:
3y + 5 = 4y − 2
=> 2 + 5 = 4y - 3y
=> y = 7
Therefore, y = 7.

In two or more complete sentences, compare the number of x-intercepts in the graph of f(x) = z2 to the
number of z-intercepts in the graph of g(x) = -22 – 5. Be sure to include the transformations that
occurred between the parent function f(x) and its image g(x).
Answer:
There is only one x-intercept for f(x) and g(x), f(x) having a minimum value of zero and g(x) having a maximum value of zero. f(x)=0 when x=0, g(x)=0 when x=4.
g(x) is f(x) reflected about the about the x-axis and shifted to the right by 4 units.

Answer:
zero
Step-by-step explanation:
Zero
Positive means that the slope moves upwards from the left to right
Negative means that the slope moves downwards from the left to right
Zero means the slope doesn't increase nor decrease
Undefined is considered the opposite in how the current slope is
2. Write an equation in slope-intercept form for the line with a slope of -9 and a
y-intercept of 18.
Answer:
y = -9x + 18.
Step-by-step explanation:
The general form is y = mx + c , where m = the slope and c = y-intercept.
[tex]\huge\boxed{Hi \: there! :)}[/tex]
We are given the slope of the line: -9.
We are also given its y-intercept: 18.
Slope-Intercept Form:
[tex]\huge\sf\{y=mx+b[/tex]
Where
m is the slope and b is the y-intercept.
Plug in the values:
y=-9x+18

A lamppost is 6 feet high and casts and 8 foot shadow. At the same time of day, a flagpole near the lamppost cast a 20 foot shadow. Using the properties of similar triangles, find the height, H, of the flagpole
Answer:
15 ft.
Step-by-step explanation:
I will assume that either both objects are standing straight. We can use similar triangles.
We can see that the side 8 is similar to the side 20, since they are both shadows. Therefore, we can set up an equation:
[tex]\frac{6}{8} =\frac{x}{20}[/tex]
we can cross multiply and get:
8x=120
solve for x:
x=15
Therefore, the lamppost must be 15 feet tall (unless it fell down but we won't talk about that)
The next number in the sequence shown below is 156.

The next number of the sequence 1, 15, 155, ...... will be 1555.
What are sequence and series?A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.
A sequence in arithmetic is an enumerated collection of items in which duplicates are permitted and order is important. It has members, just like a set. The distance of the order is defined as the number of items.
The sequence is given below.
1, 15, 155, ......
The next number of the sequence will be given by adding the digit 5 in the one's place. Then the sequence is given as,
1, 15, 155, 1,555, 15,555, 155,555,......
Then the number will be 1555.

1. The owner of a flower shop sells 18 roses for $90. What is the cost in dollars per rose? Show
or explain how you know.
Answer:
The roses are sold individualy for $5.00.
Step-by-step explanation:
To find the answer, you divide 90 (the total amount) by 18 (the number of roses). Because we are doing division, you forget about the dollar sign (for now) and do the division. 90➗18=5. Since it is money, it would be $5.00
