What is the first step in solving the equation 4.2y-5.2=18.5?

2 answers:

6 0

You would want to add 5.2 to both sides to get 4.2y by itself on one side. Then you would divide both sides by 4.2 to get y by itself. Whatever y equals is the answer. Hope this Helps!

If h(x) = 5x - 3 and j(x) = -2x, solve hlj(2)] and select the correct answer below. (1 point)

BARSIC [14]

Answer:

-23

Step-by-step explanation:

We are given the functions;

h(x) = 5x - 3 and j(x) = -2x

Now, we want to find h[j(2)]

j(2) = -2(2)

j(2) = -4

Thus;

h(-4) = 5(-4) - 3

h(-4) = -20 - 3

h(-4) = - 23

A marketing company is designing a new package for a box of cereal. They have determined that the function C(x) = 4.5 x2 models

Vlad1618 [11]

So the function is

$\\ \rm\rightarrowtail y=4.5x^2$

As we know

x²≥0
x≥0

hence domain is

$\\ \rm\rightarrowtail D_f\in R$

Least value of function is at x²=0 i.e 0

Hence range:-

$\\ \rm\rightarrowtail R_f\in [0,\infty)$
