Answer: He is not correct. The resulting will be in a different quadrant.
Step-by-step explanation: This would be much easier to answer with a screen shot of the image.
For example, if the original image is in quadrant 1, the first reflection over the x-axis places the new image in quadrant 4, "upside-down" and the second reflection over the y=x line places the new image in quadrant 2 and "oblique" to the original.
Reflecting the original over the y=-x line places the new image in quadrant 3.

Answer:
position 1 5 8 12 19 25
term -8 8 20 36 64 88
Step-by-step explanation:
(n - 1) is position ( n ∈ N)
d is the distance between the numbers in the sequence
a1 is the first number in the sequence
we have the fuction: a(n) = a1 + (n - 1)d
see in the table, with position = 1, term = -8 => a1 + d = -8
position = 25, term = 88 => a1 + 25d = 88
=> we have: a1 + d = -8
a1 + 25d = 88
=> a1 = -12
d = 4
=> a(n) = -12 + 4(n - 1)
=> term = 8, position = (8 + 12)/4 = 5
position = 8, term = -12 + 4.8 = 20
term = 36, position = (36 + 12)/4 = 12
position = 19, term = -12 + 4.19 = 64
Answer:
The required table is:
Position 1 5 8 12 19 25
Term -8 8 20 36 64 88
Step-by-step explanation:
The general formula for arithmetic sequence is:
[tex]a_n=a_1+(n-1)d[/tex]
where n is the nth term, a₁ is the first term and d is the difference.
Looking at the table, we know that
a₁ = -8 and
a₂₅ = 88
We can find the common difference d:
[tex]a_n=a_1+(n-1)d\\n=25, a_1=-8, a_{25}=88\\a_{25}=a_1+(25-1)d\\88=-8+24(d)\\88+8=24\:d\\96=24\:d\\d=\frac{96}{24}\\d=4[/tex]
So, we have d = 4
Now we can fill the remaining table.
We have to find position n, when term (a_n) is 8
[tex]a_n=a_1+(n-1)d\\8=-8+(n-1)4\\8=-8+4n-4\\8=-12+4n\\8+12=4n\\20=4n\\n=\frac{20}{4}\\n=5[/tex]
So, when term is 8, position is 5
We have to find term a_n when position n is 8
[tex]a_n=a_1+(n-1)d\\a_8=-8+(8-1)4\\a_8=-8+7(4)\\a_8=-8+28\\a_8=20[/tex]
So, when position is 8 term is 20
We have to find position n, when term (a_n) is 36
[tex]a_n=a_1+(n-1)d\\36=-8+(n-1)4\\8=-8+4n-4\\8=-12+4n\\36+12=4n\\48=4n\\n=\frac{48}{4}\\n=12[/tex]
So, when term is 36, position is 12
We have to find term a_n when position n is 19
[tex]a_n=a_1+(n-1)d\\a_{19}=-8+(19-1)4\\a_{19}=-8+18(4)\\a_{19}=-8+72\\a_{19}=64[/tex]
when position is 19 term is 64
So, the required table is:
Position 1 5 8 12 19 25
Term -8 8 20 36 64 88

A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $10 million after 4 years, as shown in the graph:
There is a graph of a line with Years on the x axis and Profits in millions on the y axis that passes through 0, negative 20 and 4, 10.
Which equation most closely represents the line depicted in the graph?
f(x) = −10x + 4
f of x equals fifteen halves times x minus 20
f(x) = 10x − 4
f of x equals two fifteenths times x minus 20
Answers
Given:
The graph passes through the points (0,-20) and (4,10).
To find:
The equation of line that most closely represents the line depicted in the graph.
Solution:
If a line passing through two points, then the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The given line passes through the points (0,-20) and (4,10). So, the equation of line is
[tex]y-(-20)=\dfrac{10-(-20)}{4-0}(x-0)[/tex]
[tex]y+20=\dfrac{10+20}{4}(x)[/tex]
[tex]y+20=\dfrac{30}{4}x[/tex]
[tex]y+20=\dfrac{15}{2}x[/tex]
Subtracting 20 from both sides, we get
[tex]y=\dfrac{15}{2}x-20[/tex]
The function form is
[tex]f(x)=\dfrac{15}{2}x-20[/tex]
f of x equals fifteen halves times x minus 20.
Therefore, the correct option is B.
Answer:
Your answer is B
Step-by-step explanation:
f of x equals fifteen halves times x minus 20

The triangle is an acute triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of angles of the triangle are
The measure of ∠ABC = 50°
The measure of ∠BAC = 50°
The measure of ∠ACB = 80°
So , all the angles of the triangle are less than 90°
So , it is an acute triangle
Hence , the triangle is acute

For 4 weeks in June, Cameron biked 3 1/4 miles each week and swam 2 1/2 miles each week. For 3 weeks in July, he biked 4 3/4 miles each week and swam 3 1/2 miles each week
Answers
Step-by-step explanation:
Given that,
For 4 weeks in June, Cameron biked 3 1/4 miles each week and swam 2 1/2 miles each week.
For 3 weeks in July, he biked 4 3/4 miles each week and swam 3 1/2 miles each week.
We need to find how much greater was the total distance Cameron bike and swim in July compared to the total distance he bike in swim in June.
In July, total distance is ,
[tex]4\dfrac{3}{4}\times 3+3\dfrac{1}{2}\times 3\\\\= \dfrac{19}{4}\times 3+\dfrac{7}{2}\times 3\\\\=24.75\ \text{miles}[/tex]
In June, total distance is :
[tex]=4\times 3\dfrac{1}{4}+4\times 2\dfrac{1}{2}\\\\=\dfrac{13}{4}\times 4+\dfrac{5}{2}\times 4\\\\=23\ \text{miles}[/tex]
Hence, in June total distance is 23 miles and in July total distance is 24.75 miles.

There are oranges that are ¥90 and apples that are ¥150.
When you buy a total of 15 of them, your total cost is ¥1890.
How many oranges and apples did you buy?
Answers
Step-by-step explanation:
If 15 oranges were bought,
the total cost would be 15 * ¥90 = ¥1350.
¥1890 - ¥1350 = ¥540.
For every orange that switches to an apple,
the cost increases by ¥150 - ¥90 = ¥60.
Number of apples = ¥540 / ¥60 = 9.
Therefore there are 6 oranges and 9 apples.
Answer:
6 oranges and 9 apples.
Step-by-step explanation:
Let the number of oranges be x then the number of apples = 15 - x.
So 90x + 150(15 - x) = 1890
90x - 150x + 2250 = 1890
-60x = -360
x = 6
and number of apples = 15 - 6
So it's 6 oranges and 9 apples.

What is the rule used to reflect the triangle ABC to its image?
A. Reflect over y = -x
B. Reflect over y = x
C. Reflect over the x axis
D. Reflect over the y-axis
Answers
Answer:
The rule used to reflect Δ ABC to its image is Reflect over y = x ⇒ B
Step-by-step explanation:
If the point (x, y) reflected across the x-axis , then its image is (x, -y) If the point (x, y) reflected across the y-axis , then its image is (-x, y) If the point (x, y) reflected across the line y = x , then its image is (y, x) If the point (x, y) reflected across the line y = -x , then its image is (-y, -x)From the given figure
∵ The coordinates of point A are (-4.5, 6)
∵ The coordinates of point A' are (6, -4.5)
→ The coordinates are switched ⇒ 3rd rule
∴ Point A is reflected over the line y = x
∴ Δ ABC is reflected over the line y = x
∴ The rule used to reflect Δ ABC to its image is Reflect over y = x
Note: Point B' on the graph should be C' and point C' should be B' (correct it)

(1.6 ÷ 12 = 0.13 recurring (0.1333333333)
3.5 hours = (60 × 3) + 30 = 210 minutes
Multiply 0.13 recurring (0.1333333333) by 210 mins.
210 × 0.13 recurring (above number) = 27.999999993 (You can round this up to the nearest whole number), which is 28 if the question asks you to but as it uses 1.6 miles, you can leave it as 27.9 or even leave the long decimal if you're not entirely sure.
