The price of Deluxe=D
the price of standard- S

D=S+5
2D+3S=47,5
2*(S+5)+3S=47,5
2S+2*5+3S=47,5
5S+10=47,5
5S=47,5-10
5S=37,5
S=37,5:5
S=7,5 $ the price of standard Chocolates

D=7,5+5=12,5$
D=12,5$

What are the discontinuities of the function f(x) =x<2-36/4x-24 ?
kipiarov [429]
Well, 2-36/4x-24 is the same as (2-24)-(36/4)x which simplifies to -22-9x. This does not have a discontinuity anywhere. If you meant to divide 36 by 4x, then x=0 would be the discontinuity since you cannot divide by 0. If you meant to have 4x-24 all in the denominator, then x=6 is the discontinuity since that would make the bottom equal 0. So it seems you need some parenthesis here somewhere for your problem to make sense.

H(t)=t^2+4t+3 what are the zeroes of the function? Write the smaller t first, and then the larger t second
Anuta_ua [19.1K]

Answer:

t = - 3, t = - 1

Step-by-step explanation:

Given

h(t) = t² + 4t + 3

To find the zeros equate h(t) to zero, that is

t² + 4t + 3 = 0

Consider the factors of the constant term (+ 3) which sum to give the coefficient of the t- term

The factors are + 3 and + 1, since

3 × 1 = 3 and 3 + 1 = 4, thus

t² + 4t + 3 = (t + 3)(t + 1) = 0

Equate each factor to 0 and solve for t

t + 3 = 0 ⇒ t = - 3

t + 1 = 0 ⇒ t = - 1

smaller zero is t = - 3

larger zero is t = - 1
