Answer:

x=4,y=9

Step-by-step explanation:

We want to solve the equation:

2y - 5x =  - 2

3y + 2x = 35

simultaneously.

Multiply the top equation by 3 and the bottom equation by 2 to get:

6y-15x=-6

6y+4x=70

Subtract the top equation from the bottom equation.

4x -  - 15x =  70 -  - 6

19x = 76

x =  \frac{76}{19}

x = 4

We substitute x=4 into 2y-5x=-2 to get:

2y - 5(4) =  - 2

2y =  - 2 + 20 = 18

y =  \frac{18}{2}  = 9

Therefore the solution to the system is

(4,9)

Amber got a raise, and her hourly wage increased from $8 to $9.50 what is the percent increase
I am Lyosha [343]

Answer:

The percent increase is <u>18.75%</u>.

Step-by-step explanation:

Given:

Amber got a raise, and her hourly wage increased from $8 to $9.50.

Now, to find percent increase.

Previous wage = $8.

Wage raised = $9.50.

So, to get the increased wage we subtract the previous wage from the wage raised:

\$9.50-\$8=\$1.50.

Now, to get the percent increase:

\frac{1.50}{8} \times 100

=\frac{150}{8}

=18.75\%.

Therefore, the percent increase is 18.75%.

Simplify completely
Mandarinka [93]

Answer: x+2 / x+ 9, x = -2, x=-9   ( A )

Solution:

Breakdown the problem into two sets

Step 1:  simplify x^2 -10x - 24

Factorize the above equation,

Multiply the last term (24) with the first term coefficient i.e. 1

Step 2: Then, find the factors of 24 in a way that when you add or subtract it sums up to 10

x2 - 12x + 2x - 24  >>>>  (x2-12x) + (2x-24) >>> take common

>>>> x(x-12) + 2( x-12)

Step 3:   (x + 2)  (x - 12)

Step 4: Step 1:  simplify x^2 - 3x - 108 using the same steps

x2 - 12x + 9x - 108 >>>>  take common x(x-12) + 9 ( x -12) >>>

(x + 9)  (x - 12) final product

Now, Simplify the equation as a whole

 (x + 2)  (x - 12) /  (x + 9)  (x - 12)                         Note:  (x - 12) cancels out  

=  (x + 2) /  (x + 9)     with x= -2 and x= -9
