Answer:
A.2
Step-by-step explanation:
X is equal to 2
If you plug in 2 for X both sides will equal each-other
2(2) + 4(2)-9 = (2) + 1
4 + 8 - 9 = 3
12-9 = 3
3 = 3
Therefore X is equal to 2

You read the first 20 pages of a book in 25 minutes. You read 36 pages in 45 minutes. Is the number of pages read
proportional to your time?
(i’ll give brainliest to best answer)
Answer:
proportional
Step-by-step explanation:
20 : 25 :: 36 : 45
Product of means = 25*36 = 900
Product of extremes = 20 * 45 = 900
Product of means = Product of extremes
So, the number of pages read is proportional to your time
how do I solve this
Answer:
Step-by-step explanation:
Rewrite this as -m divided by 4 - 2 = 3
Add the two to 3 to get 5
Multiply 5 by 4 to get 20
m = -20
Hi. I need help with these questions.
See image for question.
Step-by-step explanation:
Given
f(x) = 4x³ + 3x² - 2x - 1Divide it by the following:
(a) 2x + 1
4x³ + 3x² - 2x - 1 =(4x³ + 2x²) + (x² + 1/2x) - (5/2x + 5/4) + 1/4 =2x²(2x+1) + 1/2x(2x + 1) - 5/4(2x + 1) + 1/4 =(2x + 1)(2x² + 1/2x - 5/4) + 1/4Quotient = 2x² + 1/2x - 5/4
Remainder = 1/4
(b) 2x - 3
4x³ + 3x² - 2x - 1 = (4x³ - 6x²) + (9x² - 13.5x) + (11.5x - 17.25) + 16.25 = (2x -3)(2x² + 4.5x + 5.75) + 16.25Quotient = 2x² + 4.5x + 5.75
Remainder = 16.25
(c) 4x - 1
4x³ + 3x² - 2x - 1 = (4x³ - x²) + (4x² - x) - (2x - 1/2) - 3/2 =(4x - 1)(x² + x - 1/2) - 3/2Quotient = x² + x - 1/2
Remainder = - 3/2
(d) x + 2
4x³ + 3x² - 2x - 1 = (4x³ + 8x²) - (5x² + 10x) + (8x + 16) - 17 =(x + 2)(4x² - 5x + 8) - 17Quotient = 4x² - 5x + 8
Remainder = - 17
Step-by-step explanation:
Given
f(x) = 4x³ + 3x² - 2x - 1
Divide it by the following:
(a) 2x + 1
4x³ + 3x² - 2x - 1 =
(4x³ + 2x²) + (x² + 1/2x) - (5/2x + 5/4) + 1/4 =
2x²(2x+1) + 1/2x(2x + 1) - 5/4(2x + 1) + 1/4 =
(2x + 1)(2x² + 1/2x - 5/4) + 1/4
Quotient = 2x² + 1/2x - 5/4
Remainder = 1/4
(b) 2x - 3
4x³ + 3x² - 2x - 1 =
(4x³ - 6x²) + (9x² - 13.5x) + (11.5x - 17.25) + 16.25 =
(2x -3)(2x² + 4.5x + 5.75) + 16.25
Quotient = 2x² + 4.5x + 5.75
Remainder = 16.25
(c) 4x - 1
4x³ + 3x² - 2x - 1 =
(4x³ - x²) + (4x² - x) - (2x - 1/2) - 3/2 =
(4x - 1)(x² + x - 1/2) - 3/2
Quotient = x² + x - 1/2
Remainder = - 3/2
(d) x + 2
4x³ + 3x² - 2x - 1 =
(4x³ + 8x²) - (5x² + 10x) + (8x + 16) - 17 =
(x + 2)(4x² - 5x + 8) - 17
Quotient = 4x² - 5x + 8
Remainder = - 17

A 40 of foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4^4, where x is the number of 13-year period, models the population growth. How many foxes will there be after 26 years
Answer:
640 foxes
Step-by-step explanation:
The actual formula is [tex]y = 40 * 4^{x}[/tex]
Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.
26 / 13 = 2 periods
Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...
[tex]y = 40 * 4^{x}[/tex]
[tex]y = 40 * 4^{2}[/tex]
[tex]y = 40 * 16[/tex]
[tex]y = 640[/tex]
Finally, we can see that there should be 640 foxes after 26 years.

A square of side x is cut out of a larger square of side y. What is the area of the remaining
figure?
Answer:
The area of the remaining figure is [tex]y^2-x^2[/tex]
Step-by-step explanation:
Area of the Square Shape
Given a square of side length x, the area is calculated by the formula:
[tex]A_x=x^2[/tex]
It's given a square of side x is cut out of a larger square of side y. Please refer to the image below.
The area of the square of side length y is:
[tex]A_y=y^2[/tex]
The shaded area of the remaining figure is the difference between both areas:
[tex]A=A_y-A_x[/tex]
[tex]A=y^2-x^2[/tex]
The area of the remaining figure is [tex]\mathbf{y^2-x^2}[/tex]

what is 2p6−19=−9 I need help pls I don't understand this at all
Answer:
5/6. Is this what u are looking for?
Step-by-step explanation:
Step 1 Simplify:2x(6)-19=-9 to 12x+-19=-9
Step 2 Add 19 to both sides: 12x-19+19=-9+19. You should get 12x=20
Step 3 Divide 12 on both sides: 12x/12=10/12
x=10/12. Simplified= x=5/6
Which equation represents a line which is perpendicular to the line y = 4/3x -7
A)3x + 4y = 8
B)4x – 3y = 24
C)4x + 3y = -6
D)4y - 3x = 12
Answer:
A)3x + 4y = 8
Step-by-step explanation:
Given expression;
y = [tex]\frac{4}{3} x[/tex] - 7
A line perpendicular to this will have negative inverse slope;
the slope of the given line = [tex]\frac{4}{3}[/tex]
perpendicular line = [tex]-\frac{3}{4}[/tex]
Now;
the equation of the line is;
y = [tex]-\frac{3}{4}[/tex] x - 7
multiply through by 4
4y = -3x - 28
4y + 3x = -28

Answer:
C. x⁶y⁴/xy²
Step-by-step explanation:
Rearrange (x²y)(x⁴y³) to get
(x²x⁴)(yy³)
When multiplying numbers with exponents with the same base, you add the exponents.
So the equation above can be simplified even further to:
(x²⁺⁴)(y¹⁺³) --- (those are plus signs in between the exponents)
Simplify to
x⁶y⁴
Now you have the top of the equation simplified
so the answer is c

the bill came to $136.40 The patrons decided to leave a 15% tip what was the total bill including the tip
Answer:
$156.86Step-by-step explanation:
Total = bill + tip
136.40 + 0.15*136.40 =136.40 + 20.46 = 156.86Nolan says the relationship in the table is not proportional because the point (0, 0) does not appear in the table.
Which is the best way to explain to Nolan why he is incorrect?
A. A graph made from the table will be increasing, so it is proportional.
B. Not all proportional relationships contain (0, 0), so it could be proportional.
C. The points on the graph will have even y-coordinates, so it is proportional.
D. Even though (0, 0) is not in the table, the graph is a line through (0, 0), so it is proportional.
Answer: D. Even though (0, 0) is not in the table, the graph is a line through (0, 0), so it is proportional.
Step-by-step explanation:
The table is not included but this should be the correct answer.
Linear relationships which are proportional will have to pass through the origin which is (0,0). This does not mean that on the table, the points (0,0) have to be there.
Even if it does not explicitly appear in the table, so long as the line passes the origin, it is to be considered a proportional relationship. The (0,0) might not appear on the table because only a few points the line passed through were listed but if when the line is plotted, the line goes through (0,0), it is proportional.

The segment BC joining the midpoints of 2 sides of the triangle is
Half the length of the third side, that is
x + 31 = 2(x + 19)
x + 31 = 2x + 38 ( subtract x from both sides )
31 = x + 38 ( subtract 38 from both sides )
- 7 = x → A
The stopping distance (s) of a truck varies directly as the square of its speed (v). If a truck travelling at 50 mph requires 200 feet to stop, find the stopping distance for a truck travelling at 65 mph.
Answer:
The distance is 338ft
Step-by-step explanation:
Given
Represent distance with s and velocity with v:
When
[tex]s = 200\ ft[/tex]
[tex]v = 50mph[/tex]
Required
Determine the distance when velocity is 65mph
From the question, we understand that:
[tex]s\ \alpha\ v^2[/tex]
Convert to equation
[tex]s\ = kv^2[/tex]
Substitute 200 for s and 50 for v
[tex]200 = k * 50^2[/tex]
[tex]200 = k * 2500[/tex]
Make k the subject:
[tex]k = \frac{200}{2500}[/tex]
[tex]k = \frac{2}{25}[/tex]
To get s when v = 65.
Substitute 65 for v and 2/25 for k in [tex]s\ = kv^2[/tex]
[tex]s = \frac{2}{25} * 65^2[/tex]
[tex]s = \frac{2}{25} * 4225[/tex]
[tex]s = \frac{8450}{25}[/tex]
[tex]s = 338\\[/tex]
Hence, the distance is 338ft

Office Depot prints black and white or colored copies.Yesterday,they printed 9 black and white copies for every 2 colored copies if they print 200 color copies how many black and white copies were printed?
Answer:
900 black and white copies were printed.
Step-by-step explanation:
From the information provided, you know that they printed 9 black and white copies for every 2 colored copies and you can use a rule of three to find the amount of black and white copies that were printed if they printed 200 color copies:
9 black and white → 2 colored
x ← 200 colored
x=(9*200)/2=900
According to this, the answer is that 900 black and white copies were printed.
