Marsha has budgeted no more than $3,000 on centerpieces for the tables at the reception, which inequality represents all possibl
Black_prince [1.1K]

Answer:

x+y\leq 3000

Step-by-step explanation:

Given : Marsha has budgeted no more than $3,000 on centerpieces for the tables

x denotes the number of Guest Tables Lily Arrangements

y denotes the number of Family Table Rose Arrangements

To Find: Which inequality represents all possible combinations of x,  and y,  that Marsha can buy for no more than $3,000?

Solution :

Since there are x number of Guest Tables Lily Arrangements.

And there are y  number of Family Table Rose Arrangements

Since she cannot spend more than 3000 on centerpieces .

So, the inequality becomes:

x+y\leq 3000

Hence inequality represents all possible combinations of x and y that Marsha can buy for no more than $3,000:

x+y\leq 3000

I keep getting (10,5) or (0,5) someone pls help
rodikova [14]

Answer:

(4,-3)

Step-by-step explanation:

Multiplying the bottom equation by -6, we get -6x+12y=-60.

Adding this to the first equation gives 15y=-45, and thus y=-3.

So, it follows that 6x+3(-3)=15, and thus x=4.

Find the ordered pairs that solve the equation y=12
Rufina [12.5K]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

y = 0.5x

when x = 12

y = 0.5 · (12)

y = 6

when x = 0

y = 0.5(0)

y = 0

when x = 8

y = 0.5(8)

y = 4

when x = 12

y = 0.5(12)

y = 6

Thus, the table is completed such as:

x             y

0             0

8             4

12           6

Therefore, the ordered pairs that complete the equation y = 0.5 x are:

  • (0, 0)
  • (8, 4)
  • (12, 6)

The graph of the equation is attached below.

Describe the transformation required to obtain the graph of the given function from the basic trigonometric graph.
mamaluj [8]

Answer:

Option c. Reflection across the x-axis and vertical stretch by a factor of 7

Step-by-step explanation:

If the graph of the function y = cf(x) represents the transformations made to the graph of y = f(x) then, by definition:

If 0 then the graph is compressed vertically by a factor a.

If |c| > 1 then the graph is stretched vertically by a factor a.

If c then the graph is reflected on the x axis.

In this problem we have the function y = -7secx and our paretn function is y = secx

therefore it is true that

c = -7\\\\|-7|> 1\\\\-7.

Therefore the graph of y = secx is stretched vertically by a factor of 7 and is reflected on the x-axis

Finally the answer is Option c
