y = 11

Step-by-step explanation:

Step 1:

y = 2x - 3        Equation

Step 2:

x = 7        Given

Step 3:

y = 2 ( 7 ) - 3      Input x value

Step 4:

y = 14 - 3        Multiply

Answer:

y = 11          Subtract

Hope This Helps :)

slega [8]
 <span>Let r(x,y) = (x, y, 9 - x^2 - y^2) 

So, dr/dx x dr/dy = (2x, 2y, 1) 

So, integral(S) F * dS 
= integral(x in [0,1], y in [0,1]) (xy, y(9 - x^2 - y^2), x(9 - x^2 - y^2)) * (2x, 2y, 1) dy dx 
= integral(x in [0,1], y in [0,1]) (2x^2y + 18y^2 - 2x^2y^2 - 2y^4 + 9x - x^3 - xy^2) dy dx 
= integral(x in [0,1]) (x^2 + 6 - 2x^2/3 - 2/5 + 9x - x^3 - x/3) dx 
= integral(x in [0,1]) (28/5 + x^2/3 + 26x/3 - x^3) dx 
= 28/5 + 40/9 - 1/4 
= 1763/180 </span>

If C4=15 and C7=14, what is the result of the logical expression C4&gt;C7 true or false
kvasek [131]
The answer is True because just plug in the numbers

C4=15 and C7=14

logical expression

C4>C7

15>14

That reads to 15 is greater than 14, which is true

Given that y is directly proportional to x. If y = 30 and x= 5, write an equation that connects y with x.
Licemer1 [7]

Given:

y is directly proportional to x.

y=30 when x=5

To find:

The equation that connects y with x.

Solution:

It is given that, y is directly proportional to x. So,

y\propto x

y=kx                     ...(i)

Where, k is the constant of proportionality.

We have, y=30 when x=5. Substituting these values in (i), we get

30=k(5)

Divide both sides by 5.

\dfrac{30}{5}=k

6=k

Substituting k=6 in (i), we get

y=6x  

Therefore, the required equation is y=6x.
