The sum of two numbers is 59. the difference between 2 times the first number and 6 times the second is -34. find the two numbers.

x = 40 ; y = 19

Step-by-step explanation:

x + y = 59

2*x - 6*y = -34

x + y = 59

x = 59 - y

2*(59 - y) - 6*y = -34

118 - 2*y - 6*y = -34

- 8*y = -34 - 118

-8*y = -152

y = -152 / -8

y = 19

x = 59 - y

x = 59 - 19

x = 40

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
