Answer:
x = 1
, y = 1
Step-by-step explanation:
Solve the following system:
{2 x + y = 3 | (equation 1)
x = 2 y - 1 | (equation 2)
Express the system in standard form:
{2 x + y = 3 | (equation 1)
x - 2 y = -1 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x + y = 3 | (equation 1)
0 x - (5 y)/2 = (-5)/2 | (equation 2)
Multiply equation 2 by -2/5:
{2 x + y = 3 | (equation 1)
0 x+y = 1 | (equation 2)
Subtract equation 2 from equation 1:
{2 x+0 y = 2 | (equation 1)
0 x+y = 1 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 1 | (equation 1)
0 x+y = 1 | (equation 2)
Collect results:
Answer: {x = 1
, y = 1
Answer:
Option b ) 2.310
Step-by-step explanation:
Given that the function is

For finding when the tangent is parallel to x axis, we must find the least positive value of x for which y' i.e. derivative =0
Differentiate y with respect to x using chain rule.

Equate this to 0
Either one factor should be zero.

x=2.31 satisfies this
For the other root,

Since positive least value is asked we can say
x =2.310
Option b
Answer:
160 g of oats
0.4 l or 400 ml of milk
20 g sugar
Step-by-step explanation:
If the recipe originally serves 3 portions and we require the amount of each ingredient that is needed to make 2 portions, simply multiply each amount in the original recipe by 2/3.
Oats:

Milk:

Sugar:
