Solve this system of equations: X=? Y=? ( JUST WRITE THE NUMBER ANSWERS WITH A COMMA BETWEEN THEM)
hjlf

Answer:

Therefore the Final Solution is

x = 2 and y = 4

( 2 , 4 )

Step-by-step explanation:

Given:

y=2x                ...............Equation ( 1 )

x=-y+6         ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Substitute Equation  ( 1 ) in Equation ( 2 ) we get

x=-2x+6\\\\3x=6\\\\3x=6\\\\x=\frac{6}{3} \\\\\therefore x =2

Now Substituting x = 2 in Equation ( 1 ) we get

y =2\times 2\\\\\therefore y=4

Therefore the Final Solution is

x = 2 and y = 4

( 2 , 4 )

The heat index I is a measure of how hot it feels when the relative humidity is H (as a percentage) and the actual air temperatu
PSYCHO15rus [73]

Answer:

a) I(95,50) = 73.19 degrees

b) I_{T}(95,50) = -7.73

Step-by-step explanation:

An approximate formula for the heat index that is valid for (T ,H) near (90, 40) is:

I(T,H) = 45.33 + 0.6845T + 5.758H - 0.00365T^{2} - 0.1565TH + 0.001HT^{2}

a) Calculate I at (T ,H) = (95, 50).

I(95,50) = 45.33 + 0.6845*(95) + 5.758*(50) - 0.00365*(95)^{2} - 0.1565*95*50 + 0.001*50*95^{2} = 73.19 degrees

(b) Which partial derivative tells us the increase in I per degree increase in T when (T ,H) = (95, 50)? Calculate this partial derivative.

This is the partial derivative of I in function of T, that is I_{T}(T,H). So

I(T,H) = 45.33 + 0.6845T + 5.758H - 0.00365T^{2} - 0.1565TH + 0.001HT^{2}

I_{T}(T,H) = 0.6845 - 2*0.00365T - 0.1565H + 2*0.001H

I_{T}(95,50) = 0.6845 - 2*0.00365*(95) - 0.1565*(50) + 2*0.001(50) = -7.73

Write a recursive rule for the sequence.

-2,0,2,4,6

STEP 1:

a1 = -2

a2 = 0

a3 = 2

STEP 2:

d = a2-(a1)=a3

= d = 0-(-2)=2

STEP 3:

An = a+(n-1)d

A function will not have ANY repeating x values....it can have repeating y values...just not the x ones

so ur function is : (2,3) ,(1,3), (3,3) ....u see how u have no repeating x values
