Write the algebraic expressions.
The sum of x and y.
5 times a is added to b.
The sum of numbers x and yis multiplied by 3.
6 is added to the number b.
b and 4ab are the term. (like/unlike)

The sum of x and y: x+y

5 times a is added to b: 5a+b

The sum of x and y is multiplied by 3: 3(x+y)

6 is added to the number b: 6+b or b+6

b and 4ab are unlike terms.

Step-by-step explanation:

Hope this helps!

The sum of x and y means you have to add x+y. Also, sum is the answer to an  addition problem. So, if you add x+y, you would get the sum.

5 times a is added to b means 5 times a or 5a, and once you have the product, you add it to b, so 5a+b.

The sum of numbers x and y is multiplied by 3 You have  the sum of x and y which is x+y, then you multiply it by 3. So, you can write it as 3 times the sum of x+y, so 3(x+y).

When you are adding, you use the addition sign.

you are adding 6 to b, so b+6.

b and 4ab are unlike terms because they both don't the same two letters. Yes, they share the letter b, but they don't share the letter a, so ther are unlike terms.

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
