Question 4 (1 point) Determine whether the ordered pair (3,28) is a solution to the equation 2x- y/2 = -8 (3, 28) Is a solution
bulgar [2K]

Answer:

It is a solution

Step-by-step explanation:

Given

2x - \frac{y}{2} = -8

Required

Determine if (3,28) is a solution

(3,28) implies that:

x = 3

y = 28

To check if it is a solution, we simply substitute values for x and y in the given equation;

2x - \frac{y}{2} = -8

2(3) - \frac{28}{2} = -8

6 - 14= -8

-8= -8

Since both sides of the equation are equal; then, Yes, it is a solution

The area of a triangular block is 16 squre inches. If the base of the triangle is twice the height, how long are the base and th
klemol [59]
The area of a triangle can be calculated using the formula 

1/2 (base) (height)

Let's substitute our known values, letting x represent the value of the height of the triangle.

16  = 1/2* x* 2x

Let's Simplify!

16 = x^2

Finally, lets take the square root of both sides, to get rid of the exponent on the right side of the equation.

x= positive OR negative 4.

However, because x is equal to the height, we know that it can't be negative, so we know that it is positive 4.

The height of the triangle = 4 inches
The base of the triangle = 2h = 8 inches
