Answer:

x = 3

y = 1

Step-by-step explanation:

(2x + 4y = 10) * 2 = (4x + 8y =20)

4x = 20 - 8y

Plug that into the other equation

(20 - 8y) - y = 11

-9y = -9

y = 1

Plug this value into one of the original equations

2x + 4(1) = 10

2x = 6

x = 3

One serving of granola provides 4% of the protein you need daily. You must get the remaining 48 grams from other resources. How
Fantom [35]
For this problem, let's assign a variable for the total amount of proteins needed daily/ Let that parameter be x. Now, the 48 grams is part of the total. The other portion is the one expressed in percentage. That accounts for 4% of x. Therefore, the equation would be:

x = 48 + 0.04x
Solving for x
x = 50

Thus, you will need 50 grams of protein daily.

Write the equation of the line with a slope of 2 that contains the point (3, 9) .
mr Goodwill [35]

Answer:

Step-by-step explanation:Here the slope of the line = m = 2

The line passes through the point ( x 1 ,  y 1 ) = (   ,  9 ).

The equation of the line with slope  m  and passing through the  point ( x 1 ,  y 1 ) is given by ( y -  y 1 ) = m ( x  -  x 1 )

( y  -  9 ) =  2  (  x  -  3 )y  -  9  =  2 x -  6

Collecting terms in one side

0  =  2 x  -  y  -  6  +  9

2 x  -  y  +  3  =  0

Hope this helps x
