Answer:

x= -8 x=2

Step-by-step explanation:

x^2 +6x - 6 = 10

Subtract 10 from each side

x^2 +6x -16 =0

Factor what 2 numbers multiply to -16 and add to 6

8*-2 = -16

8-2 = 6

(x+8) (x-2) =0

Using the zero product property

x+8 =0 x-2 =0

x= -8 x=2

What is 1 7/8 Times 2 1\3

slamgirl [31]

We need to convert the mixed fractions into improper fractions.

1*8 = 8
8+7 = 15

15/8

2*3 = 6
6+1 = 7

7/3

Now we can finish and multiply

$\frac{15*7}{8*3}$

15*7 = 105
8*3 = 24

Simplify 105/24

105/24

24*4 = 96

105 - 96 = 9

4 is the whole number, and 9 is the numerator.

4 9/24

Simplify that,

9/3 = 3
24/3 = 8

4 3/8

Answer: $4\frac{3}{8}$

Graph the line giving one point and the slope. 2x-6y=12

koban [17]

Y = mx + c

this is the equation of line and here m is the slope

so, 2x-6y =12 can be changed into standard format

y = 2x/6 - 12/6
y=x/3 +(-2)

so, m = 1/3 , so slope will be 1/3

hope it helped :)
