We're told x=-5 and y=11 and asked to evaluate a few expressions. That just means substitute these values into the expressions and compute the exact numerical answer.

4y-10x = 4(11) - 10(-5) = 44 + 50 = 94

Answer: 94

x to the power of 3

x^3 = (-5)^3 = -5 \times -5 \times -5 = -125

Answer: -125

•6y to the power of 2

Probably means

6y^2 = 6(11)^2 = 6(121) = 726

Answer: 726

5(3x+2y) = 5(3(-5) + 2(11)) = 5(-15 + 22) = 5(7) = 35

Answer: 35

•(y-x) to the power of 2

(y - x)^2 = (11 - -5)^2 = 16^2 = 256

Answer: 256

Elan Coil [88]

Answer:

B) 4(x - 3)(3x - 2)

Step-by-step explanation:

12x² - 44x + 24

4[3x² - 11x + 6]

4[3x² - 9x - 2x + 6]

4[3x(x - 3) - 2(x - 3)]

4(x - 3)(3x - 2)

{ y = - 4x-23-4x-3y=13
sleet_krkn [62]

For this case we have the following system of equations:

y = -4x-23\\-4x-3y = 13

We solve by the substitution method:

We substitute the first equation in the second equation:

-4x-3 (-4x-23) = 13

We apply distributive property considering that - * - = +:

-4x + 12x + 69 = 13\\8x + 69 = 13

We subtract 69 from both sides of the equation:

8x = 13-69\\8x = -56

We divide by 8 on both sides of the equation:

x = \frac {-56} {8}\\x = -7

We look for the value of the variable y:

y = -4 (-7) -23\\y = 28-23\\y = 5

Thus, the solution of the system is (x, y): (-7,5)

Answer:

(x, y): (-7,5)
