To simplify this expression we collect like terms. The 'b' terms can be added together to get the final value:
21\cdot b + b = 21\cdot b + 1 \b = 22 \b

I need to find #1 and #2
Fittoniya [83]

Answer:

1. Angle f and s are supplementary angles, which is equal to 180, so we will: 180-35= 145

If you apply the changes below to the absolute value parent function, f(x) = 1x1,
inn [45]

If you apply "Shift 5 units to the right" and "Shift 4 units down." to the  absolute value parent function, f(x) = 1x1 you have  g(x)=|x+ 5| f(x) = |x|-4. Option A. This is further explained below.

<h3>What is a function?</h3>

Generally, a function is simply defined as an expression, rule, or law in arithmetic that establishes a link between two variables.

In conclusion, The value is added to x well before the operator with a horizontal shift left.

Hence, f(x) = |x+5|

Because this is a downshift, the vertical movement will be beyond the bars for this function, Hence f(x) = |x|-4
