use round up method to present the number 45.056 to nearest integer. If the number is 45.56, would the answer be the same ?​

45.056 = 45

45.56 = 46

Step-by-step explanation:

Given :

45.056 to nearest integer. If the number is 45.56

To round 45.056 to the nearest integer, we evaluate the value after the decimal point, if the value after the decimal point is greater Than or equal to 5, we round to 1 and add to the value immediately before the decimal point, if otherwose, we round to 0 ;

Therefore,

45.056 = 45 (nearest integer) ; 0 is less than 5

45.56 = 46 (nearest integer) ; round 5 to 1 and add to 5, to give 6

y = -1

Step-by-step explanation:

The standard form of equation of a line is y = mx+b

m is the slope

b is the y intercept

Get the coordinate of the point of interception of the line 2x - y = 9 and 3x - 7y = 19

Make y the subject of the formula in both expressions

For 2x  - y = 9

- y = 9- 2x

y = 2x - 9

Similarly for 3x - 7y = 19

-7y = 19 - 3x

7y = 3x - 19

y = 3/7 x - 19/7

Equating both expressions

2x - 9 = 3/7 x - 19/7

Multiply through ny 7

14x - 63 = 3x - 19

14x - 3x = -19 + 63

11x = 44

x = 44/11

x = 4

Since y =2x - 9

y = 2(4) - 9

y = 8-9

y = -1

Hence the coordinate of intersection is at (4, -1)

Get the equation of the line passing through (-3, -1) and (4, -1)

Slope m = -1+1/4+3

m = 0/7

m = 0

Get the intercept

Substitute m = 0 and (-3, -1) into y = mx+b

-1 = 0(-3) + b

-1 = b

b = -1

Get the required equation

Recall that y = mx + b

y = 0x + (-1)

y = -1

Hence the required equation is y = -1
