Answer:

x = 0.5

y = -1/4 or -0.25

Step-by-step explanation:

x + 6y = 2

3x + 2y = 10

Multiply a number by any of the equations to get numbers of the same variable

3x + 18y = 6

3x + 2y = 10

3x - 3x = 0

NB: subtract evenly if u subtract down from top make sure u subtract down from top throughout

16y = -4

16y/16 = -4/16

y = -1/4 or -0.25

to find the x value, any where you see y u put in the y value(-0.25)

So u'll pick just one of the equations above

x + 6(0.25) = 2

x + 1.5 = 2

x = 1.5 + 2

x = 0.5

PLEASE HELP I've tried everything 30 points!

Luda [366]

Answer:

(x+2)1x-8)=0

x=-2 or x=8

Step-by-step explanation:

The given quadratic expression is

$2 {x}^{2} - 12x - 32$

We equate this expression to zero to get:

$2 {x}^{2} - 12x - 32 = 0$

Let us divide through by 2 to get:

${x}^{2} - 6x - 16 = 0$

Split the middle term to get:

${x}^{2} - 8x + 2x - 16 = 0$

Factor

${x}(x - 8) + 2(x - 8) = 0$

Factor further to get

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

The solution are

$x = - 2 \: and \: x = 8$

8a – 6+2=-7+ 7a solve the

Kisachek [45]

A = -3

8a-6+2=-7+7a

Add 2 to -6

8a-4=-7+7a

Subtract 7a from 8a

Add 4 to -7

Then you get

A= -3

Brooke has to set up 70 chairs in equal rows for the class talent show. But, there is not room for more then 20 rows. What are t

grin007 [14]

Answer:

The answer is 2, 5, 7, 10, and 14.

Step-by-step explanation:

Let x be the number of rows. There is not room for more than 20 rows:

x ≤ 20

Since all rows must be equal, when we divide 70 by x, we must get a whole number. So, we must find all divisors of 70 smaller or equal to 20 and they are: 2, 5, 7, 10, and 14.

So, the possibilities are:

2 rows with 35 chairs in each row

5 rows with 14 chairs in each row

7 rows with 10 chairs in each row

10 rows with 7 chairs in each row

14 rows with 5 chairs in each row

Hope this helps!!

Triangle STU has reflected over line m to form Triangle S'T'U'. What is the value of y?

Lera25 [3.4K]

Answer:

D. 5

Step-by-step explanation:

The congruence of S'T' with ST tells you ...

9 = x +7

2 = x

The congruence of S'U' and SU tells you ...

4x = y +3

4·2 -3 = y = 5 . . . . substitute the value of x; subtract 3
