eliminating y

x + y = 4 .......... x 2

3x - 2y = 7 ...... x 1

2x + 2y = 8

3x - 2y = 7

_________ +

5x = 15

x = 3

substitute

x + y = 4

3 + y = 4

y = 1

x = 3 and y = 1

Answer:

D 7x( x^2y) ^1/3

Step-by-step explanation:

5x (x^2y)^1/3 +2 (x^5y)^1/3

We can simplify the second term

2 (x^5y)^1/3 = 2 (x^3 * x^2y) ^1/3

We know that (a*b) ^c = a^c * b^c

2 (x^3 * x^2y) ^1/3 = 2 (x^3 )^1/3*( x^2y) ^1/3

2*x*( x^2y) ^1/3

Replacing this into the original equation

5x (x^2y)^1/3 +2x( x^2y) ^1/3

The term inside the cube root is the same, so we can add the terms on the outside

(5x+2x) 2x( x^2y) ^1/3

(7x)( x^2y) ^1/3

B2 is A= 1/2h(bl+b2), if A=16, h=4, and b1=3<br> b2=____

Yuliya22 [10]

Answer:

b₂ = 5

Step-by-step explanation:

Substitute the given values into the formula

16 = $\frac{1}{2}$ × 4 × (3 + b₂)

16 = 2(3 + b₂) ( divide both sides by 2 )

8 = 3 + b₂ ( subtract 3 from both sides )

5 = b₂

Answer:

The angle ZLK has a value of 75 degrees.

Step-by-step explanation:

We can calculate this as:

$m\angle MLZ+m\angle ZLK=m\angle MLK\\\\(x+66)+(x+86)=130\\\\2x+152=130\\\\2x=130-152\\\\x=-22/2=-11\\\\\\m\angle ZLK=x+86=-11+86=75$

We replace the angles values in the equation, as both angles that are formed with Z (MLZ and ZLK), when added, gives as the angle MLK. This allows us to calculate x. The value for x is -11.

Then, with the value for x we can calculate any of both angles.
