Step-by-step explanation:

Answer:

Step-by-step explanation:

-2x+9y=-9 (solve for x)

-2x= -9y-9

X = - 9y/-2 - - 9/2. X = 9y/2 + 9/2

9(9/2y+9/2)-2y=2

81y/2 + 81/2 - 2y = 2

81y/2 - 2y = 2 - 81/2. 81/2 - 2 = 77/2 and -81/2 +2 = -77/2

77/2 y = - 77/2

y = (-77/2)/(77/2)

y = - 1

Answer:

[tex]3x+41[/tex] or 38

Step-by-step explanation:

If Q is the midpoint of Line PR, then lines PQ and QR add up to equal Line PR. We then get

[tex]PQ=6x+25\\QR=16-3x\\PQ+QR=PR\\6x+25+16-3x=PR\\3x+41=PR\\[/tex]

If you want to know the exact number that PR is, we can do additional steps where PQ = QR.

[tex]PQ=6x+25\\QR=16-3x\\PQ=QR\\6x+25=16-3x\\9x+25=16\\9x=-9\\x=-1\\\\3x+41=PR\\3(-1)+41=PR\\-3+41=PR\\38=PR\\PR=38[/tex]

Answer:

1) s=15

2) 15, 21, 21, 15, 30 from left to right

Step-by-step explanation:

First you turn this into an equation: s+6+s+6+s+s+2s

Collect like terms: 4s+ 12 + 2s

Simplify: 6s+12

Bring back into a full equation: 6s+12=102

Simplify= 102-12=6s

90= 6s

90/6=s

s=15

Then bring back into sides: Left side and right sides are 15 as s= 15

15+6= 21 so both top sides are 21

2×15=30

So it goes in the order from left to bottom clockwise:

15, 21, 21, 15, 30

Answer:

Value of X is 18

Step-by-step explanation:

x/3 - x/6 = 2

multiply first fraction by 3 so u get X by its self then multiply the 2 by 3

x - x/6 = 6

then multiply the fraction by 6 to get X by itself then multiply the 6 by 6 because what u do to one side u have to do to the other

2x/2 = 36/2

x= 18

The answer is f(g(x))=x^2-30x+216

Answer:

40,960

Step-by-step explanation:

To find the multiplier, set up an equation like this:

[tex]5x=-10[/tex]

The above equation will allow us to find what number, when multiplied with 5 will result in -10. If we divide both sides of the equation by 5, we'll find that the number, x, is -2:

[tex]x=-2[/tex]

We need to find the 14th term. To do this, simply multiply the lattermost number in the sequence by our multiplier, -2.

[tex]20*(-2)=40[/tex]

Since 5 is the first term in the sequence, -10 is the second term in the sequence, and 20 is the third term in the sequence, 40 is the fourth term. Now we just need to find the next ten so that we can find the 14th term. To do that, repeat the process of multiplying the lattermost number by -2 ten more times:

[tex]40*-2=-80\\-80*-2=160\\160*-2=-320\\-320*-2=640\\640*-2=-1280\\-1280*-2=2560\\2560*-2=-5120\\-5120*-2=10240\\10240*-2=-20480\\-20480*-2=40960[/tex]

Therefore, the 14th term is 40,960.

The equation of the given circle is :

(x - 3) + (y - 5) = 8

where, r² = 8

therefore, value of radius (r) = [tex]2\sqrt{2}[/tex] units

Answer:

Below.

Step-by-step explanation:

I'll  write sin x as s and cos x as c so we have:

(1 + s +c)/(1 + s - c) = (1 + c)/s

Cross multiplying:

s + s^2 + cs  = 1 + s - c + c + cs - c^2

s  + s^2 + cs = 1 + s + cs - c^2

s^2 + c^2 + s - s + cs - cs = 1

s^2 + c^2 = 1.

- that is sin^2 x + cos^2 x = 1 which is a known identity.

Therefore the original identity is proved.

Answer:

Step-by-step explanation:

-124 = -7(5x+ 6)- 6x                     Remove the brackets

-124 = -35x - 42 - 6x                   Combine like terms

-124 = -41x - 42                          Add 42 to both sides

-124+42 = - 41x                          Combine

-82 = - 41x

-82/-41 = x

x = 2

Answer:

V = π × r² × h

Step-by-step explanation:

All you need to do is multiply the base times the height and since the base is a circle whose formula is π × r², we get π × r² × h.

Step-by-step explanation:

54 = 6*9

That means there are 3 threes and 1 two

54 = 2*3 * 3 * 3

There are a pair of 3s and a two and a 3 left over.

The two and the three remain under the root sigh.

One of the pair of threes comes out of the root sign.

The other one is thrown away.

sqrt(54) = 3*sqrt(6)

Answer: x=31

Step-by-step explanation:

-4 + 2x=58

2x-4=58

2x-4+4=58+4

2x=62

2x/2=62/2

x=31

Answer:

x = 31

Step-by-step explanation:

- Combine all like terms;

8+2x-12=58

2x -4 = 58

- Add 4 to both sides.

2x = 62

- Divide both sides by 2.

x = 31
