Answer:

x = -5

y = -1

Step-by-step explanation:

here's the solution :-

  • subtracting equation 1 from equation 2 we get,

=》-8x - 4y + 8x - 6y = 44 - 34

=》-10y = 10

=》y = -1

plugging the value of y in equation 2 we get :-

=》-8x - 4y = 44

=》-8x - (4 × -1) = 44

=》-8x + 4 = 44

=》x = 40 ÷ -8

=》x = -5

Find the values of x and y, write your answer in simplest form.
tamaranim1 [39]

Answer:

Step-by-step explanation:

You have a 30-60-90 triangle. The sides of a 30-60-90 are in the ratio 1:√3:2.

The side opposite the 30° angle is 5, so the side opposite the 60° angle is 5√3, and the side opposite the 90° angle is 5×2 = 10.

x = 5√3

y = 10

The cost for a company to produce x t-shirts can be modeled by
lana [24]

Answer:

P(x)=-2x^2+34x+98

The cost function is given by c(x)=21x-98

And the revenue function is given by  r(x)=55x-2x^2

The profit function is the difference of revenue function and the cost function. Mathematically, we can write

p(x)=r(x)-c(x)

Substituting the values, we get

p(x)=55x-2x^2-(21x-98)

p(x)=-2x^2 + 34x = 98

Therefore, the profit function is

p(x) = -2x^2 + 34x + 98
