Los primeros días de enero, el representante del mercado recibió cierta cantidad de di- nero, hizo una operación y se dio cuenta que habían pagado 15 personas. ¿Cómo puede

saber la cantidad recibida?

15

425

option: d is correct

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
