The expression will look like 9-(3+2) and will evaluate to 4

Step-by-step explanation:

We have to put the values of x, y and z in the given expression to find the result.

Given:

$x-(y+z)$

And

$x=9\\y=3\\z=2$

Putting the values

$9-(3+2)\\=9-5\\=4$

The expression will look like 9-(3+2) and will evaluate to 4

x equals 3 to the power of 4 times 5 cubed times 7 times 11 to the power of 4 y equals 3 squared times 5 to the power of 4 times

Vadim26 [7]

Answer:

$gcd(x, y) = 3^2\times 5^3\times 7$

Step-by-step explanation:

We are given the following in the question:

$x = 3^4\times 5^3\times 7\times 11^4\\y = 3^2\times 5^4\times 7\times 13^4$

We have to find prime factorization for gcd(x, y).

To find the greatest common factor for x and y ,we find the common factors in the prime factorization of x and y.

The common factors are:

$g.c.d(x,y) = 3^2\times 5^3\times 7 = 7875$

The prime factorization for gcd(x,y) is

$7875\\= 3\times 3\times 5\times 5\times 5\times 7\\ = 3^2\times 5^3\times 7$

Amy has $30 to spend on snacks and beverages for herself and her friends at the movie theater. The cost for nachos was $5. The cost for each beverage was half the cost of the nachos

Let x be the number of nachos and y be the number of beverages

The cost for nachos was $5. So the cost of 'x' nachos = 5x

The cost for each beverage was half the cost of the nachos.

The cost of each beverage = $\frac{5}{2}= 2.5$

so the cost of y beverage = 2.5 y

Cost of x nachos + cost of y beverage = total amount spend

5x + 2.5y = 30

Now we find x and y intercept

When Amy does not buy any beverages we put y=0

5x + 2.5(0) = 30

5x = 30

x= 6. The x intercept is (6,0)

When Amy does not buy any nachos we put x=0

5(0) + 2.5y = 30

2.5y = 30

y=12. The y intercept is (0,12)

The graph is attached below

(b) The graph is a straight line. From the graph we can see that when Amy does not buy any nachos then she can spend #30 to buy 12 beverages .

when Amy does not buy any beverages then she can spend #30 to buy 6 nachos.
