PLEASE HELP....... Solve the system of equations using the Addition method. 2a + 3b = -1 3a + 5b = -2

1 answer:

4 0

2a+3b = -1 | *3
3a +5b = -2 |* -2

6a+ 9b = -3
-6a -10b = 4
------------------
/ -b =1
b= -1

2a + 3b= -1
2a + 3* -1 = -1
2a -3= -1
2a = 3-1
2a=2
a=2:2
a=1

Help me please,Thanks

Ugo [173]

The answer to this question would be the last choice (this data has no outliers)

Explanation: The reason for this is that an outlier is basically any number or value that kind of stands off or is very separated from a set of data.

For example, if I had the numbers 1,2,3,2,9,5,7,5,8,4 and 47, 47 would definitely be an outlier as it's significantly greater than the rest of the data.

The data shown in your question doesn't vary a lot though, (it's contained within a range of 65 and 80- no number seems to be radically different).

The equation 6x - 5y = 14 is written in standard form. Which point lies on

dimaraw [331]

Answer= H (-1, -4)

Explanation= 6(-1) - 5(-4) = 14
(-6) + (20) = 14
14=14 * it works !
GOODLUCK!

A six-sided number cube labeled 1 through 6 is rolled 500 times. An odd number is rolled 325 times. Compare the experimental pro

Komok [63]

The actual probability of having odd is 3/6=1/2
so no of odds theoretically is 250

but it is 325
so, experimental is higher than theoretical
so answer is B !
and you can go for that !
