2x - 2y = -12
- 2y = -2x - 12
y = x + 6

4x - 7 (x + 6) = -15
4x - 7x - 42 = -15
-3x - 42 = -15
-3x = 27
x = -9

y = -9 + 6
y = -3

(-9 , -3) is the solution

Can someone please help as I'm not sure how to tackle this step by step? Especially question b, d, g, j, k, l. Not how sure to d
Arisa [49]

Step-by-step explanation:

√a = 1√a so we can solve them easily:

b) 3√7 -√7= 3√7 - 1√7 =( 3-1)√7= 2√7

d) 5√6 - 2√6+√6= (5-2+1)√6 = 4√6

g) √2+2√2= 3√2

j) √5+5√5 - 3√5 = 3√5

k) 2√3 + √3 - 5√3= -2√3

I) 5√11 + 7√11 - √11 = 11√11

solmaris [256]

Answer:

3 games

Step-by-step explanation:

Here, the same amount of money was spent at different golf clubs. The amount spent at Man vista golfing is (3 + 7.5g). The amount spent at Pinz golfing is (12 + 4.5g)

We equate both to yield the following:

(3+7.5g) = (12+4.5g)

7.5g - 4.5g = 12 -3

3g = 9

g = 9/3

g = 3

When the outliers are removed how does the mean change? Dot plot with one on 18, 2 on 38, one on 40, 3 on 44, one on 46, one on
Vitek1552 [10]
18,38,38,40,44,44,44,46,48....
the mean with the outlier (18) included is : 360/9 = 40

38,38,40,44,44,44,46,48
the mean with the outlier (18) excluded is : (360 - 18) / 9 = 342/9 = 38

so when the outlier is removed, the mean is 2 points less
