which of the following equations has the solution set {-3}

Question

4x+8=4

4x-8=-4

4x+8=-4

4x-8=-4

Answer 1

The equation that has the solution set {-3} is

4x+8=-4.

If we solve this for x:

4x = -4 - 8

4x = -12

x = -12 / 4

x = -3.

Answer 2

which correctly shows the area formula for a trapezoid, A= 1/2 h (b1 + b2)

Answer 3

The area formula for a trapezoid is correctly shown as:

A = 1/2 * h * (b1 + b2)

where:
A is the area of the trapezoid,
h is the height of the trapezoid,
b1 and b2 are the lengths of the two bases of the trapezoid.

Answer 4

what is the undefined value for the equation 14 = 7x/9+4x

Answer 5

To find the undefined value for the equation, set the denominator equal to zero and solve for x.

So, to find the undefined value, set 9+4x = 0.

Then we get 4x = -9, so x = -9/4 = -2.25.

So, the undefined value for the equation is x = -2.25 because it would make the denominator zero and division by zero is undefined in mathematics.
