adding and subtracting polynomials

Answer:

y= x/4 -9

Step-by-step explanation:

Parallel lines have the same slope, and if we know the line intercepts the y-axis at (0,-9) we can use this for our b-value in slope intercept form.

Answer:

240 cm², A = 300 cm², and 540 cm²

Step-by-step explanation:

1) The area of a parallelogram is A = bh, so:

A = (20)(12)

A = 240 cm²

2) Similarly, the area of a rectangle is A = bh, so:

A = (15)(20)

A = 300 cm²

3) The composite area is the sum of both the rectangle's area and the parallelogram's area, so:

240 cm² + A = 300 cm² = 540 cm²

Answer:

Distribute this and you get [tex]16s + 18 -4s + 6[/tex].

This simplifies to [tex]12s+24[/tex].

Answer:

P(P, then Y)=(1/11)(1/10)=1/110

Step-by-step explanation:

The number of letters in probability is 11.

There is 1 P.

The probability of drawing a P on draw 1 is the number of ways of drawing a P, which is 1, divided by the number of ways of drawing any letter, which is 11.  Thus:

Probability of drawing a P on the first draw is 1/11.

There are now 10 letters left. There is 1 Y. so

Probability of drawing a Y on the second draw given that you drew a P on the first draw is 1/10.

The probability of drawing a P on the first draw and a Y on the second draw is

(probability of a P on draw 1)(probability of drawing a Y on draw 2, given a P on draw 1)

P(P, then Y)=(1/11)(1/10)=1/110

Answer:

X=4

Step-by-step explanation:

90-58=32

32÷8=4

The diagonals are bisected perpendicular so it equals 90. subtract 58 and simplify

Answer:

vertex = (4, 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

y = (x - 4)² + 3 ← is in vertex form

with vertex = (4, 3 )

Answer:

5 meters

Step-by-step explanation:

Since, the 3m and 4m are NOT the hypotenuse (since the hypotenuse is diagonal) we can use the pythagorean thm.

Answer: 145.8

Step-by-step explanation:   you have to divide 45 and 25 to get 1.8, then you get 81 and you multiply 81 x 1.8 to get your answer.

Answer:

The formula to solve this would be:

X x Y = 13

There are at least two combinations of two numbers that you can multiply together to get 13.

Step-by-step explanation:

y = 2x + 4

(5) = 2(1) + 4

5 = 2 + 4

5 = 6 (false statement)

Answer:

Step-by-step explanation:

To figure this out, you just need to extend the graph. You can do this by extending the already existing line or find the equation of the line. I found the equation of the line which is y = 0.5x . Now once you have the extended graph, you need to graph the given points.

(25,10)

(10,25)

(20,10)

(15,3)

After graphing these points, check which one is on the line. You would see that the point (20,10) is on the line. Now that you know this, you figure out which answer had this point. The answer that has this point is answer C.

An extended graph can be seen below

Given:

Principal value = 40000

Rate of compounded interest = 20%

Time = 2 years

To find:

The interest.

Solution:

Formula for amount is

[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]

Where, P is principal, r is rate of interest and t is time in years.

Putting the given values, we get

[tex]A=40000\left(1+\dfrac{20}{100}\right)^2[/tex]

[tex]A=40000\left(1+\dfrac{1}{5}\right)^2[/tex]

[tex]A=40000\left(\dfrac{6}{5}\right)^2[/tex]

[tex]A=40000\left(\dfrac{36}{25}\right)[/tex]

[tex]A=57600[/tex]

Now, the formula for interest is

[tex]I=A-P[/tex]

[tex]I=57600-40000[/tex]

[tex]I=17600[/tex]

Therefore, the amount of compound interest is 17,600.

Answer:

Number of e-books Eli needs to read per month is Greater than 6

Step-by-step explanation:

Given - Over the next 17 months, Eli needs to read more  than 102 e-books.

             The inequality 17x > 102 represents the number of e-books he  

              needs to  read per month.

To find - Solve the inequality to find the  number of e-books Eli needs to  

               read per month.

Proof -

As given, Over the next 17 months Eli need to read more than 102 e-books

i.e 17x > 102

⇒x > [tex]\frac{102}{17}[/tex]

⇒x > 6

∴ we get

Per month Eli needs to read more than 6 e-books.
