Answer:

B=fh

Step-by-step explanation:

I think?

Basically divided by b to get h over b and then times by h to get b=fh (you want to be get on its own)

Answer:

h÷f or h/f

Step-by-step explanation:

f × b = h so h ÷ f = b

Answer:

1.) If. y=mx+b.

2.) subtracting b from both sides. y−b=mx.

3.) dividing both sides by m. y−bm=x.

4.) flipping the sides (to make it look more normal) x=y−bm.

Answer:

7/3x  +  2/3 = 7/9x  -  5/6

7/3x  -  7/3x  +  2/3 = 7/9x - 7/3x  -  5/6     (7/9x-7/3x--->7/9x-21/9x---> -14/9x)

2/3= -14/9x - 5/6

2/3+5/6 = -14/9x - 5/6 + 5/6  -  (2/3 + 5/6---> 4/6 + 5/6---> 9/6 ----> 3/2)

3/2 = -14/9x

3/2   /    -14/9  =  -14/9x   /   -14/9 -   (3/2   /   -14/9 ------>  3/2  x  -9/14 ----->

Answer:

B

Step-by-step explanation:

plug in (-9, 3):

-9 is the x value and 3 is the y value, so plug it in like that.

6(-9)-3^2 = 14 ?

solve.

-54-9=14?

-63=14? NO!

Then try (2, -4)

2 is x-value, -4 is y-value.

6(2)-(-4)^2=14?

use order of operations (Perenthesis, Exponents, Multiplication/Division, Addition/Subtraction) (PEMDAS)

12-(16)=14?

-4=14? NO!

The answer is B, niether is a solution.

Answer:

Step-by-step explanation:

There are a lot of ifs in this problem. The generator has to be a fair one. Any one of the 11 numbers must be equally likely to happen. Second, the sequence must not be the same each time she turns it on. Assuming both are true, then the numbers she will get are

9 10 11  for one number

9 10 11 for the other number

P(x>8) = 3/11 * 3/11 = 9/121

Answer:

0.000007

Step-by-step explanation:

The millionth place is 6 spots to the right of the decimal.

Our number is 0.000007328

6 spots to the right is 0.000007 (328)

3 is less than 5, so we do not round up.

The answer is 0.000007

Answer:

First term = a = 125

Step-by-step explanation:

Question: find the number of shoppers on the first day

This is a geometric progression question

The sum of the terms = 671

Sum of a geometric sequence,Sn = (ar^n - 1) / (r - 1)

Where,

n = number of term in the sequence.

a = first term in the sequence.

r = common ratio

r = 1 + 20%

= 1 + 20/100

= 1 + 0.2

= 1.2

n = 4 (first 4 days)

Sn = (ar^n - 1) / (r - 1)

Sn = 671 where n = 4

671 = {a × 1.2^(4) - 1} / 1.2 - 1

671 = {a × 2.0736 - 1} / 0.2

671 = (2.0736a - a) / 0.2

671 = 1.0736a / 0.2

671 = 5.368a

Divide both sides by 5.368

a = 671 / 5.368

a = 125

Step-by-step explanation:

The solution is where the two lines cross each other:

(-1,3) and (2,6)

The answer is B.

Answer:

The slope is 2.

Step-by-step explanation:

To find the slope we can take two points from the graph (in this example I'll use (3, 2) and (4, 4)) and input them in this expression: [tex]\frac{y2-y1}{x2-x1}[/tex]

[tex]\frac{4-2}{4-3}[/tex]

Solve:

4 - 2 = 2

4 - 3  = 1

[tex]\frac{2}{1}[/tex] = 2

The slope of the line connecting Saturn and Earth is 2.

Answer:

(2, 1): Yes

Step-by-step explanation:

5x - 3y = 7

-2x + 7y = 3

(2, 1) = 5(2) - 3(1) = 7

10 - 3 = 7

7 = 7

-2(2) + 7(1) = 3

-4 + 7 = 3

3 = 3

Yes

Answer:

Answer:

(3, 1)

Step-by-step explanation:

The coordinates of point G is (c) (3,1)

The coordinate points are given as:

[tex]\mathbf{E = (0,4)}[/tex]

[tex]\mathbf{F = (1,3)}[/tex]

The ratio is given as:

[tex]\mathbf{m : n = 1 :2}[/tex]

Line ratio is given as:

[tex]\mathbf{(x,y) = \frac{mx_2 + nx_1}{m + n}, \frac{my_2 + ny_1}{m + n}}[/tex]

Point F is at the partitioned point.

So, we have:

[tex]\mathbf{(1,3) = \frac{1 \times x_2 + 2 \times 0}{1 + 2}, \frac{1 \times y_2 + 2 \times 4}{1 + 2}}[/tex]

[tex]\mathbf{(1,3) = \frac{x_2 }{3}, \frac{y_2 + 8}{3}}[/tex]

Multiply through by 3

[tex]\mathbf{(3,9) = (x_2, y_2 + 8)}[/tex]

By comparison, we have:

[tex]\mathbf{x_2 = 3}[/tex]

[tex]\mathbf{y_2 + 8= 9}[/tex]

Subtract 8 from both sides

[tex]\mathbf{y_2 = 1}[/tex]

Hence, the coordinates of point G is (c) (3,1)
