Can someone help me! it would mean the world! and tysm! <3

Answer:

x=2, y=-1

Step-by-step explanation:

[tex](x+7)+(-y-2)i=9-i[/tex]

the (x+7) part corresponds to the 9 and the (-y-2) corresponds to the coefficien of i.

[tex]x+7=9[/tex]

[tex]x=2[/tex]

[tex]-y-2=-1[/tex]

[tex]y=-1[/tex]

Answer:

Step-by-step explanation:

It looks like every time the coefficient increases by 3 while the exponent increases by 1.

[tex]\\45\\\sum 3(n+1)x^{n}\\n = 0[/tex]

Notice it starts at zero so 3 is multiplied by (x+1) to make it start from 0

The exponent is simply n, because at the start is it zero [tex]x^0=1[/tex], then 1, then 2, so on.

The upper limit is 45 because 45 - 0 = 45 terms

Answer:

40 students in each bus.

Step-by-step explanation:

Subtract the 8 extra students from the total to get the total number of students who rode in buses. Then divide that total by 6.

248-8=240

240/6=40

40 students in each bus.

Answer:

Constant monomial

Step-by-step explanation:

Monomial means that there is only one term, so constant trinomial cannot be correct.

Quintic monomials have a degree of 5 and quadratic monomials have a degree of 4, but this has a degree of zero, so this must be a constant monomial.

I hope this helps you. Have a nice day.

Answer:

B 50

Step-by-step explanation:

Option 1) 2/5 = 20/x  |  20/2 = 10 so x = 10  |  5 times x 10 =50

Option 2) dogs 2 to cats 5  |  2/5 = 20/x  |  .40 = 20/x  |  .40x = 20  |  x = 50

Option 3) you can look and see that 20 is 10 times more than 2 and therefore infer that x is 10 times more than 5 which is 50

Answer:

351.9 m²

Step-by-step explanation:

[tex]SA=2\pi r^2+2\pi rh[/tex] where r is the radius of the base and h is the height of the cylinder

We're given the diameter of the base, which is 8 m. Therefore, the radius is 4 m (after dividing by 2).

Plug in 4 as r and 10 as h

[tex]SA=2\pi (4)^2+2\pi (4)(10)\\SA=2\pi (16)+2\pi (40)\\SA=32\pi +80\pi \\SA=112\pi[/tex]

Therefore, the surface area of the cylinder is approximately 351.9 m² after rounding to the nearest tenth.

I hope this helps!

Answer:

x = -7 and x = 4

Step-by-step explanation:

that's the answer

Given:

Slope of a line = 3

Line passes through the point = (2,7)

To find:

The equation of the line.

Solution:

The point slope form of a line is:

[tex]y-y_1=m(x-x_1)[/tex]

Where, m is the slope of the line.

The line passes through the point (2,7) and slope of the line 3. So, the equation of the line is:

[tex]y-7=3(x-2)[/tex]

[tex]y-7=3x-6[/tex]

[tex]y=3x-6+7[/tex]

[tex]y=3x+1[/tex]

Therefore, the correct option is 3.

Answer:

[tex]2x^2+ 8x -12[/tex]

Step-by-step explanation:

Given

[tex]P = 3x^2 + 8x - 16[/tex]

[tex]Result = x^2 - 4[/tex]

Required

The quantity subtracted

Let the subtracted quantity be Q. So, we have:

[tex]P - Q = Result[/tex]

[tex]3x^2 + 8x - 16 - Q = x^2 - 4[/tex]

Collect like terms

[tex]Q = 3x^2 - x^2+ 8x - 16 + 4[/tex]

[tex]Q = 2x^2+ 8x -12[/tex]

The quantity subtracted is: [tex]2x^2+ 8x -12[/tex]

Answer:

Step-by-step explanation:

Answer:

707,957

Step-by-step explanation:

x= 518*tan(42°) + 518*tan(25°) =518*(tan(42°)+tan(25°))≈518*1.367=707.957

Answer:

707,957

Step-by-step explanation:

Answer:

11.09units

Step-by-step explanation:

Find the diagram attached

The radius of the circle is line projecting from the center to the circumference. Hence AB is the radius of the circle.

To get AB, we will use the pythagoras theorem as shown;

Given

AC=22

BC=19

AC² = AB²+BC²

22² = AB²+19²

AB² = 22²-19²

AB² = 484-361

AB² = 123

AB = √123

AB = 11.09

Hence the radius of the circle is 11.09units

Answer:

-56 maybe

Step-by-step explanation:

-2*-7=14

8*-7= -56

Answer:

yes

Step-by-step explanation:

Answer:

7x -10 > 56

Step-by-step explanation:

For this you simply write what the sentence states. Ten less means you are subtracting 10 from 7 times a number, x. So, 7x -10. The statement also says this is greater than 56, so put >56, for 7x-10>56.

Answer:

0.60 more

Step-by-step explanation:

Sandwich: 1.25

Milkshake: 0.65

We need to find the difference between the 2

1.25 - 0.65 = 0.6

A sandwich costs 60 cents MORE than a milkshake

Answer:

120 times

Step-by-step explanation:

There are 5 people to fill the first place, 4 remaining to fill the second, 3 remaining to fill the third, 2 remaining to the fourth place and only 1 remaining to fill the fifth. That means there are 5 factorial (5!) ways. 5! = 5 x 4 x 3 x 2 x 1 = 120.

Answer:

$135.30

Why:

Take the 112.75 and multiply it by 1.2, or in other words 120%. You get 135.3, or in a money situation, $135.30. Good luck.

Answer:

  (x +8)^2 +(y +1)^2 = 16

Step-by-step explanation:

The standard form equation for a circle with center (h, k) and radius r is ...

  (x -h)^2 + (y -k)^2 = r^2

For your center and radius, the equation is ...

  (x -(-8))^2 +(y -(-1))^2 = 4^2

  (x +8)^2 +(y +1)^2 = 16
