1. tickets to a concert were $5 for children and $10 for adults. if attendance at one show was 800, and the total receipts for that show were $7000, how many adults attended?

The number of adults attended was 600

Step-by-step explanation:

Let

x ----> the number of children attended

y ----> the number of adults attended

we know that

-----> equation A

----> equation B

Solve the system by graphing

The solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (200,600)

see the attached figure

therefore

The number of children attended was 200 and the number of adults attended was 600

answer: a and b

step-by-step explanation:

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
