B) exactly one solution
C) no solution
D) infinitely many solutions

Answer:

(9-9x) - (3-x)

Step-by-step explanation:

(4x2 -9x +1) - (5x2 -x -7)

4x2+1= 9. 5x2-7= 3

(9-9x) - ( 3-x)

Answer:

I am assuming you want the percentage increase in the price.

Step-by-step explanation:

The percentage increase is ( 15/50) * 100

= 15 * 2

= 30%.

Answer:

544 acres

Step-by-step explanation:

There is 100% in a whole.

1% is 1/100th of the whole, or 0.01 of it. We get this because 1/100 = 1/100 = 0.01

Similarly, 0.8/100 = 0.008. We then multiply the decimal by the total to get

(0.008) ( 68000) = 544 acres

Answer:

14

Step-by-step explanation:

5x-3+ x+9 + 90= 180

6x+ 96=180

6x=180-96

6x=84

x=84/6

x=14

Answer:

The first one is c, I’m pretty sure, the second one is a white block, and I don’t fully understand the last question but I’m pretty sure you’re correct

Step-by-step explanation:

Answer:

C. (0,-3)

Blank

D. (4,-5)

Step-by-step explanation:

(-1,-5)is point before translation (+1,+2)

(0,-3) after translation

Ok second one

90 degree counterclockwise rotation about the origin rule

A(x,y) becomes A'(-y,x)

n=(-5,-4) ok so -4 becomes positive 4

(4,-5)

Answer:

C.  [tex] \dfrac{1}{3x + 1} [/tex]

Step-by-step explanation:

[tex] \dfrac{x + 2}{x^3 + 2x^2 - 9x - 18} \div \dfrac{3x + 1}{x^2 - 9} = [/tex]

Factor all polynomials.

[tex] = \dfrac{x + 2}{x^2(x + 2) -9(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]

[tex] = \dfrac{x + 2}{(x^2 - 9)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]

[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]

To divide by a fraction, multiply by its reciprocal.

[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \times \dfrac{(x + 3)(x - 3)}{3x + 1} [/tex]

Cancel out common factors in the numerator and denominator.

[tex] = \dfrac{1}{3x + 1} [/tex]

Answer:

205 minutes

Step-by-step explanation:

Step one:

given data

We are told that Luca's goal is to practice violin for 300 minutes in a week

He has practiced 45 minutes and 50 minutes for Saturday and Sunday already

that is in all, 45+50= 95minutes

Required

The remaining minutes of practice

Step two:

the deficit in practice is

300-95= 205 minutes

Answer: (x, y) --> (x, -y)

Step-by-step explanation:

This is a reflection over the x-axis so its only the y-intercept that changes.

Answer:

its a reflection

Step-by-step explanation:

If it were a rotation, it wouldnt have overlapped.

If it were a translation, It would have been the wrong way up and not overlapping.

When reflected over line x, it will overlap because it stays rigid and does not change shape or size.

Answer:

Find square root

a 11×11

B 30×30

C 27×27

Answer:

I would think it is 8

Step-by-step explanation:

By assuming the triangles are equal to each other in a way that the larger triangle is the smaller triangle's length times 2. For example, one side of the smaller triangle is 11 so times 2 would be the larger triangle's side. So, by dividing 16 by two, you would get 8. Hope this helped and that I did it correctly!

Answer:

m∠ONB = 81°

Step-by-step explanation:

If angle MNJ and angle ONB are congruent and MNJ is 81 degrees and OJ is a straight line then ONB should also be 81 degrees in which the other side is 99 degrees.

Infinity solutions

Answer:

2.5x10^3= 2,500

5x10^6= 5,000,000

Step-by-step explanation:

Here is a great trick that I always keep in mind whenever you are squaring 10 you add that many zeros for example.

10^4= 10000 (there are 4 zeros).

Answer:

Answer:

8x squared

Step-by-step explanation:

all you do is multiply the 4 and 2 to get the 8 and the x's multiply together causing it to square it making it 8x squared

Answer:

m = -2

Step-by-step explanation:

Look at the attached image. First, we divide both sides by 7 to get m + 5 = 3. Now, we subtract 5 from both sides to get m = -2. Now, we substitute m for -2. As we can see, it checks out.

The solution of expression is,

m = - 2

We have to give that,

An expression to solve,

7 (m + 5) = 21

Now, simplify the expression as,

7 (m + 5) = 21

Divide both sides by 7,

m + 5 = 21 / 7

m + 5 = 3

Subtract 5 both side,

m = 3 - 5

m = - 2

So, The solution is, m = - 2
