Given b(x) = |x+4| , what is b(-10)

6

Step-by-step explanation:

|-10+4| = |-6|= 6

inside the | | the equation is done normally. that's why it has a negative at first. then, once getting rid of the bars, you change the number to a positive

Step-by-step explanation:

We are given the function:

We want to find b(-10). Therefore, we must plug -10 in for each x.

Solve inside of the absolute value symbol. Add 4 to -10 ⇒ -10+4= -6

Absolute value represents how far away a number is from 0. It is always positive.

-6 is 6 away from 0. Therefore, the absolute value of -6 is 6.

b(-10) is equal to 6.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
