Answer:

Step-by-step explanation:

First remove the parentheses.

As the sign outside the second parentheses is  a + then the signs of the terms inside stay the same.

So the first one + (-3x +2) is just -3x + 2.

All the others on the left column are answered in the same way.

No. 4:

(-2x + 10 + (-8x - 1)     Just remove the parentheses, we get:

-2x + 10 - 8x - 1           (we leave out the + before the second parentheses).

= -2x - 8x + 10 - 1        

= -10x + 9

6. 8x + 8 + ( -6x - 1)

= 8x + 8 - 6x - 1

= 8x - 6x + 8 - 1

= 2x + 7.

- the other expressions on the right side column are solved in the same way.

Citrus2011 [14]

Answer:

157.6

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score,

μ is the population mean, and

σ is the population standard deviation.

From the question:

Mean = 140

Standard deviation = 40

Recidivism score = x score = ??

z = z score of 67th percentile = 0.44

Hence,

0.44 = x - 140/40

Cross Multiply

0.44 × 40 = x - 140

17.6 = x - 140

x = 140 + 17.6

x = 157.6

Therefore, his corresponding recidivism score is 157.6

Mariulka [41]
It would be estimated about 2,100 trouts I would say, since 7,500 divided by 50 is 150 so 150 x 14 = 2,100 trouts :)

Do same-side interior angles have to be on the same (in this case) horizontal line?
Romashka [77]

if the horizontal lines are all parallel, then yes, as long as the angles are on the same side. If the horizontal lines are parallel but the angles are on opposite sides, then no. If the horizontal lines are not parallel, then it would require more work to figure it out

The graph shows the relationship between time
musickatia [10]

Answer:

The machine can make 24 bottles of soda per minute

Step-by-step explanation:

Looking at the graph of the relationship, we can see that the number of bottles per minute simply represent the slope of the line

Thus, by calculating the slope using the given points, we can have the number of bottles per minute

We have the formula as;

m = (y2-y1)/(x2-x1)

(x1,y1) = (4,96)

(x2,y2) = (6,144)

m = (144-96)/(6-4) = 48/2 = 24
