Answer:

x=5, y=-2

Step-by-step explanation:

9x + 5y =35

-2x-5y=0

Add the equations together

9x + 5y =35

-2x-5y=0

----------------------

7x  = 35

Divide each side by 7

7x/7 = 35/7

x = 5

Now find y

9x+5y = 35

9(5) +5y = 35

45 +5y =35

Subtract 45 from each side

45-45 +5y = 35-45

5y = -10

Divide each side by 5

5y/5=-10/5

y = -2

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 4x + 3y = 12 ( add 4x to both sides )

3y = 4x + 12 ( divide the terms by 3 )

y = \frac{4}{3} x + 4 ← in slope- intercept form

with slope m = \frac{4}{3} and y- intercept c = 4

---------------------------------------------------

Given

- 5x + 3y = - 9 ( add 5x to both sides )

3y = 5x - 9 ( divide the terms by 3 )

y = \frac{5}{3} x - 3 ← in slope- intercept form

with slope m = \frac{5}{3} and y- intercept c = - 3

n+−3.66=1.04

n−3.66=1.04

Step 2: Add 3.66 to both sides.

n−3.66+3.66=1.04+3.66

A 16-ounce bottle of orange juice says that it contains 200 milligrams of vitamin C, which is 250% of the daily recommended dosa
Andrei [34K]

80 milligrams is the amount of vitamin C that is considered to be 100% of the daily recommended requirement for adults.

<h3>What is the daily recommended dosage of vitamin C for adults? </h3>

Parameter

  • The amount of liquid included in the bottle is 16 ounces.
  • The vitamin C content of the bottle comes to a total of 200 milligrams.

Since the orange juice container that has a capacity of 16 ounces states that it has 200 milligrams of vitamin C, this means that it fulfills 250% of an adult's recommended daily requirement for vitamin C. Then, for one hundred percent of the daily allotment,

As a result, we are able to draw the conclusion that the amount of vitamin C that is considered to be 100% of the daily recommended requirement for people is 80 milligrams.
