harkovskaia [24]

Answer

7,0

Step-by-step explanation:

Substitute -6y+7 into problem one where the x is

distribute the 2 and subtract the 9 y and you will get

-21y+14=14

subtract 14 from both sides and it will be -21y=0 so y will be 0

substitute the 0 into equation 2 and find x=7

An architectural drawing lists the scale as 1/4" = 1'. if a bedroom measures 312" by 514" on the drawing, how large is the bedro
marusya05 [52]

The length of the bedroom exists at x = 9 and y = 6.

<h3>How to estimate the length of the bedroom?</h3>

From the given information, we get

Then  $\frac{(1/4)}{(9/4)}  = \frac{1}{x}

Solve this for x.

simplifying the value of x we get

Equate (1/9) to 1/x.

x = 9 (feet).

Convert 1.5 inches to feet using a proportion:

$\frac{(1/4)}{(1.5)}  = \frac{1}{y}

Solve this for y.

simplifying the value of y we get

(1/4)y = 3/2

Multiply both sides of the equation by 4.

y = 6

Therefore, the length of the bedroom exists at x = 9 and y = 6.

To learn more the value of x refers to:

ivanzaharov [21]
Variable A is x. Variable B is y. (x,y)

2 , 2, 4, 5, 6, 7, 8, 9

Mean is computed by adding all the numbers in the data set and dividing it by its count.

2 + 2 + 4 + 5 + 6 + 7 + 8 + 9 = 43

43 / 8 = 5.375 rounded to 5.4

Which sequence follows the rule 2n + 6, where n represents the position of a term in a sequence? 6, 8, 12, 18, . . . 6, 12, 18,
melamori03 [73]

ANSWER

8, 10, 12, 14, . . .

EXPLANATION

The given rule for the sequence is :

f(n)=2n+6

The domain for a sequence is the set of natural numbers.

When n=1,

f(1)=2(1)+6=8

When n=2,

f(2)=2(2)+6=10

When n=3,

f(3)=2(3)+6=12

When n=4,

f(4)=2(4)+6=14

Therefore the sequence that follows the given rule is

8, 10, 12, 14, . . .
