16:10, 24:15, 32:20. You can multiply, divide, as long as it simplifies to 8:5 it's equivalent.

A line passes through the point (9,6) and has a slope of
Semmy [17]

Answer:

y = 4/3x - 6

Step-by-step explanation:

y = mx + b

if m = 4/3 and passes through (9,6) then

6 = 4/3(9) + b

6 = 12 + b

b = -6

then y = 4/3x - 6

Here is some information about 26 houses.a,b and c are all different numbers.Number of bedrooms:1,2,3,4,5.Number of houses:7,a,b
kkurt [141]

Answer:

[a,b,c]=[4,2,5] or [a,b,c]=[2,4,5]

Step-by-step explanation:

Given

\begin{array}{cccccc}{Bedroom} & {1} & {2} & {3} & {4} & {5} \ \\ {Houses} & {7} & {a} & {b} & {c} & {8} \ \end{array}

n = 26

Median = 3.5

Required

Find a, b and c

Median is calculated as:

Median = \frac{n+1}{2}

Median = \frac{26+1}{2}

Median = \frac{27}{2}

Median = 13.5th

This means that the median is the average of the 13th and 14th item.

\begin{array}{cccccc}{Bedroom} & {1} & {2} & {3} & {4} & {5} \ \\ {Houses} & {7} & {a} & {b} & {c} & {8} \ \end{array}

Since the median is Median = 3.5 (average of 3 and 4),

and:

3 \to b \to 13

4 \to c \to 14

This implies that c begins at 14

So, the number of houses bedrooms 4 and 5 is:

c + 8 = 26 - 14 +1

c + 8 = 13

c = 5

Also

7 + a + b + c + 8 = 26 ---- sum of total frequency

a + b + c = 26 - 7 - 8

a + b + c = 11

Substitute c = 5

a + b + 5 = 11

a + b = 11 - 5

a + b = 6

Since a, b and c are different, then

a and b cannot be 5 because c = 5

a and b cannot be 3 because a = b =3

b \ne 0 because b ends at 13

a

So, possible sets are:

[a,b]=[2,4]

[a,b]=[4,2]

Include c, we have:

[a,b,c]=[4,2,5] or [a,b,c]=[2,4,5]

Select the correct answer.<br> What is the solution to the equation?
Ierofanga [76]

Answer:

B

Step-by-step explanation:

\sqrt{x} + 6 = x ( subtract 6 from both sides )

\sqrt{x} = x - 6 ( square both sides )

x = (x - 6)² ← expand using FOIL

x = x² - 12x + 36 ( subtract x from both sides )

0 = x² - 13x + 36 , that is

x² - 13x + 36 = 0 ← in standard form

(x - 4)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 9 = 0 ⇒ x = 9

As a check

Substitute these values into the equation and if both sides are equal then they are the solutions.

x = 4

left side = \sqrt{4} + 6 = 2 + 6 = 8

right side = x = 4

Since 8 ≠ 4 then x = 4 is an extraneous solution

x = 9

left side = \sqrt{9} + 6 = 3 + 6 = 9

right side = x = 9

Thus the solution is x = 9 → B

All of the following expressions simplify to -5x + 7, except ( x - 2) - (6 x - 9) (5 x + 1) - (-10 x + 6) -4 x + 2 x + 7 - 3 x (
storchak [24]

Answer:

(5 x + 1) - (-10 x + 6)

5x +1 + 10x - 6

25x - 5

Step-by-step explanation:

(x - 2) - (6x - 9)

x - 2 - 6x + 9 =

-5x +7

(5 x + 1) - (-10 x + 6)

5x +1 + 10x - 6

25x - 5

-4 x + 2 x + 7 - 3 x

-5x + 7

(4 x + 3) + (-9 x + 4)

4x +3 -9x + 4

-5x + 7
