Answer:

a=(c+2b)/5

Step-by-step explanation:

Like terms in one side to subject a.

When exchanging sides make sure u do inverse operations. Therefore;

9a - 4a = c + 2b

5a = c + 2b

a = (c+2b)/5

A line of best fit predicts that when x equals 28 y will equal 27.255 but y actually equals 26 what is the residual in this case

Kobotan [32]

Answer:

The answer is -1.255 for residual value.

Step-by-step explanation:

We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:

Residual value = Observed value - predicted value

Residual value = 26 - 27.255

Residual values = -1.255

Micheal solved this inequality as shown: step 1: -6(x + 3) + 10 < -2 step 2: -6x - 18 + 10 < -2 step 3: -6x - 8 < -2 st

<h3>Answer: addition property of inequality</h3>

================================================

Explanation:

These are the steps to focus on

step 3: -6x - 8 < -2

step 4: -6x < 6

The move from the third step to the fourth step has us adding 8 to both sides. Therefore, we use the addition property of inequality.

That property has four forms

If $a > b$ then $a + c > b+c$
If $a < b$ then $a+c < b+c$
If $a \ge b$ then $a + c \ge b+c$
If $a \le b$ then $a+c \le b+c$

It's similar to the idea of starting with a = b, then adding c to both sides to get a+c = b+c

We add the same thing to both sides to keep things balanced.

Match the sequence with the correct indicated term.

algol13

1) an = a1 + d*(n-1) => a20 = -4 + (-9)*19 = -4 - 171 = - 175
1) ---> C)

2) a81 = 20 + 4*80 = 340;
2) ---> A)

3) a12 = ?
3) ---> B) or D).
