What is the answer to this math question

Answer: x = 7

Step-by-step explanation:

Subtract both sides by 3

X+3-3 = -4 - 3

X+0 = -7

X=-7

Answer:

-7

Step-by-step explanation:

x+3=-4

x=-4-3 (subtract 3 from both sides)

x=-7 (combine like terms)

Answer:

C: 36 × 10^6 m²

Step-by-step explanation:

Given the side length of a square = 6 × 10³m,

To solve for the area of a square, use the following formula:

A = S² where:

S = side of the square

Substitute the given value for the side into the formula:

A = S²

A = (6 × 10³)²

A = 36000000 or 36 × 10^6 m²

NOTE:

6 × 10³ is also the same as 6 × 1000 = 6000,

(6 × 10³)² is essentially 6,000² = 36,000,000

Therefore, the correct answer is C) 36 × 10^6

Answer:

The identity sinA sin(A+2B) - sinB sin(B+2A) = (sinA)^2 - (sinB)^2 is proved below.

Step-by-step explanation:

sinA sin(A+2B) - sinB sin(B+2A) =

sinA ( sin(A) cos(2B) + sin(2B) cos(A) ) - sinB (sin(B)cos(2A) + sin(2A)cos(B) ) =

sinA( sinA [cos^2(B)- sin^2(B)] + 2 sin(B) cos(B) cosA ) - sinB( sinB(cos^2A-sin^2A)+2 sinA cosA cos(B) ) =

sin^2A(cos^2B-sin^2B) + 2 sinB cosB sin(A) cos(A) - sin^2B(cos^2A-sin^2A) - 2 sinA sinB cosA cosB =

sin^2A(cos^2B-sin^2B) - sin^2B(cos^2A-sin^2A) =

sin^2Acos^2B - sin^2Asin^2B - sin^2Bcos^2A + sin^2Bsin^2A =

sin^2Acos^2B - sin^2Bcos^2A =

(1 - cos^2A)(cos^2B) - (1 - cos^2B)(cos^2A) =

cos^2B - cos^2A cos^2B - cos^2A + cos^2B cos^2A =

cos^2B - cos^2A =

1 - sin^2B - (1 - sin^2A) =

sin^2 (A) - sin^2 (B)

Answer:

I got x = 20

Step-by-step explanation:

what i did was 8x - 25 = 7x -5, i then did  8x - 25 + 5 = 7x -5 +5 then you get 8x - 20 = 7x  I then did 8x - 20 -8 = 7x -8 you would get -20 = -1x or -x and -20/-1 = x = 20 I hope this works : )

if 9m away from deep point, m1 also away from 9m to radius line.

so if we draw 2 x 2y to 1 half side of circle, y is connected with 9m, x is connected to 6m.

2 x = 150 sec

if i say 1 x 6m 2x 12m

x =75 sec =12.5 sec

(2x +2y ).2 is whole circle round

Answer:

f(3) = 100

Step-by-step explanation:

Using the recursive formula and f(1) = 1 , then

f(2) = - 10 f(1) = - 10 × 1 = - 10

f(3) = - 10 f(2) = - 10 × - 10 = 100

Use the law of cosines:

Substitute the values:

Use law of cosines

[tex]growth\:=(\frac{present \: value}{past \: value})^{ \frac{1}{n} } \: - 1 [/tex]

past value = 1700 people

n = 2005 - 1983 = 22

growth rate = 190%

present value = ?

then,

[tex]190\% = ( \frac{?}{1700})^{ \frac{1}{22} } - 1[/tex]

1.9 = (x/1700) ^(1/22) - 1

1.9 + 1 = (x/1700) ^(1/22)

2.9 = (x/1700) ^(1/22)

log 2.9 = 1/22(logx - log 1700)

log2.9 = 1/22logx - 1/22log1700

log2.9 + 1/22log1700 = 1/22logx

log(2.9 * 1/22(1700)) = 1/22logx

log 224 = 1/22logx

log(224 - 1/22(x)) = 1

log(224 - 1/22(x)) = log 10

224 - 1/22(x) = 10

(234) * 22 = x

x = 5148.

Answer:

$6

Step-by-step explanation:

This is for one pencil to each student. Since each box is $3, and she has 25 students, you would figure out how many students are left out with one box, and since you only have one left, you only need one more box. That would mean two boxes, so $3x2= $6

Step-by-step explanation:

y - 3 = 2 ( (-1) +1 )

y - 3 = 2 ( 0 )

y - 3 = 0

y = 3

Answer:

{(0, -4), (1, -2), (2, 0), (3, 2), (4, 4)}

Input values (x) = {0, 1, 2, 3, 4}

Output values (y) = {-4, -2, 0, 2, 4}

Step-by-step explanation:

Given the linear equation, y = 2x - 4, you could practically choose any input value (for x), to have an output value (for y).

If x = 0:

y = 2(0) - 4

y = 0 - 4

y = -4

First ordered pair: y-intercept =  (0, -4)

If x = 1:

y = 2(1) - 4

y= 2 - 4

y = -2

Second ordered pair: (1, -2).

If x = 2:

y = 2(2) - 4

y= 4 - 4

y = 0

Third ordered pair: x-intercept =  (2, 0).

If x = 3:

y = 2(3) - 4

y = 6 - 4

y = 2

Fourth ordered pair: (3, 2).

If x = 4:

y = 2(4) - 4

y = 8 - 4

y = 4

Fifth ordered pair: (4, 4).

Your input values (x) = {0, 1, 2, 3, 4}

Your output values (y) = {-4, -2, 0, 2, 4}
