When their reports cards came back, pete, chris, and dina realized that they shared an amount of a’s in the ratio 4: 2: 5. if pete got 14 more a’s than chris, how many a’s did dina get?

Could someone with number 1 and 2

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
