Answers

Answer 1

Answer:

9514 1404 393

Answer:

108, 77

Step-by-step explanation:

Let x represent the larger part. Then ...

x + (x -31) = 185

2x = 216

x = 108

x -31 = 77

The two parts are 108 and 77.

What is the slope of the
points (4, -2) and (-4, -4)?

Answers

Answer:

= 1/4

Step-by-step explanation:

We can find the slope given two points by using the following formula

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

= (-4 - -2)/(-4 -4)

= (-4+2)/(-4-4)

= -2/-8

= 1/4

Answer:

I think the slope is 1/4

Step-by-step explanation:

if you use the slope equation y1-y2/x1-x2, then you get (-2 - -4)/(4 - -4), which is 2/8, which is 1/4

*We can to find the upper limit of the data by using the values given in the options.
If 2
the upper limit is 8 + 2*0.7 = 9.4

If 1
the upper limit is 8 + 1*0.7 = 8.7

If 0
the upper limits is 8+ 0*0.7 = 8

If 3
the upper limit is 8 + 3*0.7 = 10.1

Therefore, the answer is
3

Which property is illustrated by the equation (a+b)+c=c+(a+b)

Answers

Associative property of addition Which property is illustrated by the equation (a+b)+c=c+(a+b) is the associative property of addition. The associative property of addition groups addends together which still yields the same sum regardless of the clustering or grouping set.
For example:
1.           1 + (2 + 3) = 6 = (1 + 2) + 3
2.           1 + (2 + 7) = 10 = (1 + 2) + 7
3.           550 + (20 + 5) = 575 = (550 + 5) + 20
